I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O

Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.**

A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it:

- Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have.

- My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's.

- I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose...

- I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS.
______________________
Q2) What is your maximum budget before rebates/shipping/taxes?**

* A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK).
______________________
Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.**

A3) IMMEDIATELY! :)
______________________
Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)**

A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\* 
______________________
Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?**

A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference?
______________________
Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.**

A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean).
______________________
Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?**

A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science).
______________________
Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)**

A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well.

- This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\*

- I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\*

- Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\*

- Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts.

- Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?)
______________________
Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?**

A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports.
______________________
Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?**

A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though.

______________________

______________________
Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc...

Naturally, I have GPU's. Specifically;

At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one.

I also have some GTX 1080 TI's but those are already spoken for, sorry.

It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP.


In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well...
Rig 1 = EPIC NAS SYSTEM
Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL

Oh, I almost forgot... The current routers I'm using are...
1X Netgear Nighthawk 6900P (Modem + Router)
1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one)
1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices.
---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :)


Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years.

TIA for assisting in any way possible. Gotta love the internets!


THE END.

EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here...

I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent.

One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind.

I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids.
Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).*
I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows:

EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else...
(Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT).
Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner:

*** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\*
Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. =
'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat.

I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale.

Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/.

THE END (Round#2)

I had like 3 friends ask me how to build a PC in the past week so I made this to help them.

(Reddit Edit: Help my improve the document with productive constructive comments on what I got wrong or messed up! Im only human lol

Beginners basic guide to building your own PC as of early 2018
(EDIT: Sorry for being a MSI/Corsair Fanboy)
Heres a collection of thoughts to consider when building your own personal PC
As always Id personally use PCPartPicker.com to configure your parts and for further thoughts on compatibility.
First off building a computer is 100% based around what you plan to use the computer for.
Here are a few uses and generic ideas of what to go for. Audio Editing: Lots of small tasks that need to be completed quickly without lag. - Fast Processor( >4GHZ) - Fast RAM (MHZ) -At least 16 gigs! - Fast Storage, SSD manditorily - M.2 or PCI for best performance. - Shitty Graphics card, graphics card there only to keep the cpu from doing other tasks when working. - Can be a few generations or years old. - Many screens for lots of plug in windows to be open Video Editing: Lots of large to render and files to read. - Multi core processor the more the merrier - SSD for fast read/write of large video files. - Insane graphics card, AMD graphics cards are debatibly better but the nvidia Quadro series are specific for video rendering. Gaming: No more than 4 cores intense graphics card - 92% of games are not coded for more than 4 cores so why spend the extra money for it. - SSD for quick load screens - Nvidia cards, 10 series, the higher the number the better. Titan cards for MAXIMUM OVERDRIVE! Coding: quick processor for lots of small tasks. Ergonomic peripherials? - Dear god please dont use a mechanical keyboard so that your coworkers dont kill you. Home office: Everything can be a few gens behind so you can get the best power per dollar spent. - Sorry that Gateway doesnt exist anymore. I guess try Dell...

Advice on Building a Mining rig on a Budget

I have most of a computer pre built, the nice thing about it is that it runs, I plan on fully upgrading it eventually but I was wondering what I would have to buy in order to maximize output of bitcoins.
I've heard that buying a nice video card will improve output.
Anything else I need to make it run faster? Ram? I'm sure a fast processor helps... Any other suggestions?

My Experience: From FX-8350 to R7-1700

Upgrading from an FX-8350 to a R7-1700.
Just a bit about me – I have been building computers since the mid 80’s. I missed the 8-inch floppy disk era, but came on board when dual 5.25” was considered mainstream and a 10-megabyte full-height HDD was the mark of a power user. The first computer I built for my own enjoyment was an AMD X5-133 (a factory overclocked 486 faster than the Pentium-75), and I’ve used a wide variety of systems since then, including a Pentium Pro-200 which served me well in college and a K6-2 which I took to quite a few LAN parties. While I’ve always had Intel notebooks, my PC’s have been AMD for quite some time now. I decided to upgrade my current main machine, which is an FX-8350 with a mild 4.4Ghz overclock. I was using 2x8GB Crucial Ballistix DDR3-1600 and a Sapphire Radeon Fury Nitro. While I know the R5-1600x would be a better bet for a pure gaming build, I have a soft spot for 8-core machines. I had been tempted to pull the trigger on an i7-7700k for a while, but the timing never worked out. But when I found the R7-1700 at a deep discount and an X370 motherboard on the shelf next to it – I couldn’t resist the siren call of a new build.
Here are my thoughts about the process:
AM4 is physically the same as AM3 from a build perspective, except for the mounting holes. I don’t know what was so important about making the holes have different offsets, but this makes it much more difficult to get quality cooling. Not all manufacturers have brackets yet, and I’m still waiting on Cooler Master to release the brackets for my Siedon 240.
The new motherboard feels very different from my AM3 board. My FX-8350 sat on an ASUS M5A99FX Pro R2.0. It was, for lack of a better word, a very workstation-ish board. 4 PCIx16 slots, 10x USB ports (2 of the USB 3.0), triple USB 2.0 front panel headers (and a USB 3.0 front panel header as well), eSATA on the rear panel, beefy VRM and Northbridge cooling, Toslink output for audio, and so on. The board itself is full of tiny components, support chips, and ports. Granted, many of these connectors are outdated (eSATA and USB2.0), and the PCIe is only 2.0 instead of current-gen 3.0, but there is a LOT of connectivity. Few people paired an FX chip with triple of quad-GPU for gaming, but I know a fair number of people used these for bitcoin mining back before there was widespread ASIC support and back then GPU mining was the most cost-effective way to mint cryptocurrency. Extra PCIe slots could be used for dedicated video capture, PCI-based storage, a RAID card, etc... Having 4 full-size slots allows this kind of flexibility. The new motherboard is an Asrock Fatal1ty x370 Gaming K4. It does not feel very workstation-ish at all. It has only two 16x PCIe slots (and when they are both in use they are only 8x), 8 USB ports on the rear panel, and a much less “busy” motherboard. Very few support chips litter its surface. Instead of a workstation component, it feels much more like a luxury consumer product. This is not a bad thing – just something I noticed while building the system. The rear IO shield is red and black to match its gaming aesthetic, it includes things like premium audio (including a very nice headphone amplifier for the front panel connectors), and while it only has 8x USB ports on the back, 6 of them are USB 3.0 and two of them (including a type-C connector) are USB 3.1 gen2. It includes RGB LED’s under the chipset heatsink and three separate RGB LED controller ports (one of which is used for the boxed cooler), Intel gigabit Ethernet, and dual M.2 slots (one of which connected directly to the CPU). It is very different in “feel” from the older ASUS board, even down to things like a shroud for the external connectors and metal-reinforced PCI slots. I must say, its more aggressive appearance and near-empty areas appeal to me. It does, however, funnel the builder into a particular configuration: limited fast storage through the M.2 slots, slow(er) storage through the 6x SATA ports, all external devices should be USB 3. Personally, these limitations didn’t restrict me for this build, since that was how I was going to set it up anyway, but the fewer connectivity choices might cause some pause for others. The only thing I don’t like about this board is the 20 second POST times. 20 seconds every time. Resuming from sleep is very fast, just reboots are slow. That’s really it. I have no substantive complaints other than that – well, and the memory speed limitations – more on that below.
The Wraith Spire cooler is without doubt the best looking box cooler I’ve ever seen. The symmetrical cylinder look, combined with the LED logo and RGB ring are very striking. I can see why many people have asked to order one, though I think for the 1700X and 1800X they are better off without it. I’ll explain why further down.
Initial hardware setup was very easy. I was able to flash to the newest 2.0 BIOS without any hassle using a DOS USB flash boot drive. The 2.0 BIOS has the newest AGESA code from AMD, as well as support for the R5 processors and better DDR4 compatibility. I didn’t want to cheap out on RAM since apparently Ryzen is sensitive to DDR4 speeds for the latency between cores. I bought the cheapest 16GB DDR4-3200 kit I could find (the EVGA SuperSC 2x8GB), for which I paid $115. While I was not able to get it to boot at 3200, I could get 2933 simply by activating XMP, then manually changing the speed from 3200 to 3000. I then tested it with MemTest86 for two complete cycles, which it passed without errors. I have encountered zero memory issues with these RAM sticks running at 2933. Since this motherboard does not officially support DDR4-3200 at all, I figure this is a good outcome. I am curious to know whether anyone has gotten 3200 on this board – that is, whether the lack of 3200 memory on Asrock’s QVL is a marketing issue or an actual hardware limitation – but I didn’t want to spend nearly double that amount in order to get AM4 verified memory (G.Skill’s FlareX), and 2966 seemed fast enough from the benchmark results I had read.
My old setup had a Samsung 850 EVO 256gb SATA6 drive as the primary boot/gaming drive. It seemed plenty fast but it had become too small for my needs, so this seemed like a good opportunity to buy a new SSD. I originally thought the NVMe drives would be out of my price range, but I bought the Intel 600p 512GB drive for only $10 more than I would have paid for a premium SATA6 drive. Though the 600p is without doubt the SLOWEST NVMe drive out there, it has 3x the read speed as the SATA6 drives, and most of what I am doing with it is trying to get quicker load times. If I was using it for professional workloads (as a video editing scratch drive, for example), I would need much higher sustained write speeds and then Samsung would be the obvious answer. I just didn’t want to spend an extra $80 on write performance that I’d never notice, and the 600p has been an excellent boot/gaming drive.
Ok, back to the Wraith Spire. I tend to have bad luck with the silicon lottery. My FX-8350 was not able to be stable above 4.4Ghz with reasonable temperatures. I was hoping I would be able to get better results from the R7-1700, since general reports indicated that it overclocked well. Unfortunately, it is difficult to tell how good of an overclock I am getting since I can find no good information about maximum recommended temperatures for this chip. Some people say 75c is the maximum safe temp. Others say 75c is a fine everyday 24/7 temp. Others say they are running it at 80c all the time without any issues at all. Steve at Techspot was getting 88c and 90c when overclocking the 1600X and 1500X using the stock coolers and without any instability – were those dangerous temps or totally fine? Nobody seems to know. I like my overclocks to be set-and-forget. I want to get it dialed in and then leave it for years without worrying that it will burn up or degrade or that in this or that application I have to turn back to stock speeds because of the thermals. Since I don’t know what max safe thermals are, I just have to guess based on stock thermals.
For stock speeds, the Wraith Spire does a good job. It is very quiet, and after a few BIOS fan-curve tweaks, it keeps the chip around 35-38 at idle, and around 68-70 on Prime95 (Small FFT, for maximum temperature generation). Incidentally, it also hits 70 if I run Cinebench a bunch of times in a row as well, so I don’t consider the Small FFT test to be totally unrealistic for the load this chip might encounter. From what I can tell, these are good normal temps. I can get 3.5Ghz by simply changing the multiplier and leaving the voltage at stock. This gives Cinebench numbers around the 1550 mark (roughly 6900k levels). Prime95 shows a modest boost in temperatures of 3-4 degrees C, and was stable even for several hours. If I push it to 3.6Ghz at stock voltage the system is unstable. At 3.7Ghz (the 1700’s boost speed for single-threaded loads) it is stable only if I give it 1.3v. While that is a totally fine voltage (AMD recommends up to 1.35v for 24/7), the Wraith Spire cannot handle a Prime95 Small FFT load anymore. I shut down the test and reverted the OC when the CPU read 89c. Given the fact that the Spire was meant to cool a 65w chip (and so probably is rated at no more than 85-95w), this is not a terribly surprising temperature – I wish I knew if it was dangerous. I have no doubt that a 240mm radiator or even a decent tower cooler will be more than enough to cool down my 3.7Ghz R7-1700. I am a little jealous of the people who just set the multiplier to 3700 and are good to go – lower voltages probably mean the Spire would be enough. But for me, it was not to be. I was halfway tempted to see at what temperature the chip would reduce its clock speed, but I didn’t want to burn up a chip I had just bought – might as well wait until I get bigger and better cooling to OC it to the 3.8-3.9 I hope it will reach.
Other than the OC temps it has been smooth sailing. Gaming feels more fluid than with the FX, even in games that I always thought were GPU-limited and/or running at 60fps with VSYNC on. Especially games that are sensitive to single-core performance (Heroes of the Storm is my latest addiction) there is a definite boost in 1% low and 0.1% low FPS. I have been using the Ryzen Balanced power plan from AMD and it seems to do a fantastic job keeping temps low when idle and letting the cores ramp up really fast when needed. I need to test whether the lack of core parking prevents it from hitting the 3.7Ghz boost as much as the regular Balanced plan allows. I think a simple CineBench single-thread comparison will do the trick.
I also tried streaming a bit – and it was able to generate 1080p60fps at x264-medium settings without being noticeable while in game. Later I edited some video of my kids – the final render speed was SOOOO fast. I am, on the whole, very happy with my upgrade. I get better single-core performance, much much better multi-core performance, along with faster disk speeds, and a more modern platform (with RGB lighting, M.2, USB 3.1, etc…).
Now if only I could find out appropriate temperatures…..

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

On Sep 18 Poloniex announced delisting of 8 more assets. That day they took a 12-80% dive showing their dependence on this one exchange.
Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.".
Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred)
The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights.
A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

New people please read this. [upvote for visibility please]

I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can.
Preface
Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here.
If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier.
Mining. What is it?
Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section.
Mining Hardware
While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much.
Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it.
So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy.
Should I mine?
Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats

Hardware Fundamentals
CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with.
RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory.
HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats)
GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like.
PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption.
MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less.
PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied.
When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info.
Mining Software
Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head)
Mining Pools
Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself.
How do I connect to a pool?
Most pools will give you a tutorial on how to but the basics are as follows:
  • Signup for a pool
  • Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
  • Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
  • Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability
This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine:
Hardware cost: The cost of your physical hardware to run this whole operation.
Power: Measured in $/KwH is also known as the operating cost.
Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon.
Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously.
Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones.
coinwarz
I like this one cause it is simple. The fields are self explanatory. Try it.
bitcoinwisdom
I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account.
Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it!

USB Hub for mining

Hey guys,
I am currently trying to get into the bitcoin mining with the hopes of having a steady output of some satoshis. I am quite aware of the current state of the mining business and have run the calculations. So: I am not looking for a quit break even, I just want a steady flow of like 2000 satoshis a day.
To achieve that I have purchased two GekkoScience 2-Pac and I intend to get more over time.
What is missing is the USB hub. I am quite unsure what would be the best pick. What I intend to have is a hub that enables me to have like 5 of these asics pointing upwards and still having at least one, better two, ports free to also run USB fans. And all ports should deliver maximum power (14W) so that I can run the miners on full speed.
Does anyone have any suggestion for such a hub?
Short summary for the hub I want:
I somehow guess that there is not the perfect hub I want. But I hope that at least with the help of you guys I get to the next best fit ;)
Thanks in advance!

Zeus/Gaw ASIC Setup Guide for Linux/Raspberry Pi

So I recently I became quite interested in mining and cyptocurrencies in general. So interested in fact that I bit the bullet and decided to buy myself a GAW Fury.
I then spent some time doing research on how to set up a GAW or Zeus ASIC on Linux, in particular on a Raspberry Pi, and have found most guides to be awful. The reason they are so bad IMHO is that they assume quite a bit of prior knowledge, either with Linux or mining, and give very little instructions. So I have tried to put together a guide that requires very little prior knowledge.
It is my aim that anyone could get their shiny new asic up and mining in no time using this guide. Anyway, I present...

The Complete Noobs Guide to Setting Up a Zeus or Gaw ASIC on Debian/Ubuntu/Raspberry Pi

Resources

About Cyrptocurrencies and Their Jargon

If you are new to cryptocurrencies and how they work I suggest taking a look at this series of KhanAcademy videos. They are for Bitcoin but the theory is the same. I found them very helpful when it came to understanding what mining actually does and the mechanics of cyrptocurrencies.
Also take a look at sircamm22 his info found here, is great and breaks down a large number of concepts. I slightly disagree with no. 21 regarding preordering. Just exercise common sense.

Linux

If you are new to Linux you could follow along by simply typing in the commands. However I highly recommend taking the time to learn what you are doing. This course is a great place to start.

Computer Setup

By the end of this section you will have your device turned on, fully setup and connected to the internet with.
Note: Commands to be typed into the command line will be displayed like this:
echo Hello World

Desktop/Laptop

For laptops and desktops already running Ubuntu or Debian I will assume you have setup your internet setup as part of the installation.
If not: There are plenty of guides out there and the installation/setup process is very easy. A good place to start for Ubuntu is here.
Now open up a terminal window. Ctrl + alt + t on a standard Ubuntu installation.
If you plan on using this PC without a monitor I would suggest installing an SSH Server.
These commands will be discussed later on in the guide.
sudo apt-get -y install openssh-server
sudo service openssh-server start

Raspberry Pi

The Raspberry Pi Foundation has put together a great guide in PDF format.
Use NOOBS it will save you a lot of trouble. NB: Some SD cards don't support NOOBs but will work fine if the image is put on using a different method.
Here is a great guide for setting up the Raspberry Pi SD card from Elinux.org. In fact it's a great place to start for anything RPi related. Raspberry Pi hub at Elinux.
Once the SD card is setup you will need to insert it into the Raspberry Pi and boot. Install Raspbian from the NOOBs menu and wait.
Follow this guide by Adafruit for first time setup. You will need to enable SSH Server.
I suggest not starting the desktop on boot. It can be easily run from the command line by typing startx.
Follow this guide by Adafruit to setup your network. Found here. No need to do this if you set up previously in the first time config.
We will also at this point want to setup ssh. Again I will point you to an Adafruit guide.
Once done exit back to a standard command line interface. This can be done in LXDE by using the power off menu located in the bottom right corner.

Miner Setup

Installing BFGMiner

If you want to the Raspberry Pi or PC without a monitor go ahead and SSH into your device.
So now you should be staring at a command line interface whether on the device with a monitor or via SSH.
First things first lets make sure we are all up to date. This will update our package list from the repositories and upgrade them to the newest version. "-y" Will simply say yes to any prompts.
sudo apt-get update && sudo apt-get -y upgrade
We are going to need to install some useful tools. Git-core is how we will clone and download BFGMiner from GitHub and Screen allows multiple command line instances and means if we exit out of ssh session or quit Terminal on Ubuntu, BFGMiner will continue to run.
sudo apt-get install git-core screen
We also need to download some other tools/dependencies to ensure that BFGMiner will compile successfully.
sudo apt-get -y install build-essential autoconf automake libtool pkg-config libcurl4-gnutls-dev libjansson-dev uthash-dev libncursesw5-dev libudev-dev libusb-1.0-0-dev libevent-dev libmicrohttpd-dev libc-bin
Ok now change into your home directory.
cd ~
And clone BFGMiner by Darkwinde.
git clone https://github.com/Darkwinde/bfgminer.git
Once the download has completed move into the bfgminer directory.
cd bfgminer
The following steps may take a while.
Now run autogen.sh
sudo ./autogen.sh
You will need to make the configure script execuitable.
sudo chmod +x ./configure
Now configure bfgminer
sudo ./configure CFLAGS="-O3" --enable-scrypt
Now lets make!
sudo make
Install BFGMiner
sudo make install
One more thing...
sudo ldconfig

Running BFGMiner

If you haven't already plug in your ASIC.
Just confirm your system is recognising the ASIC.
lsusb
Its output should look similar to this (no need to type this in):
Bus 001 Device 005: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Yep there it is our ASIC listed as device 005. There is no need to install any drivers, unlike in windows, as they come in the kernel.
Now lets actually start BFGMiner.
You will want to start a screen session to ensure BFGMiner doesn't quite when you exit.
"-S" is the option for starting a new screen session. You can replace "miner" with anything you like.
screen -S miner
Now you can run the commands below.
Here is a sample of what you should type. You will need to replace somethings with your own values.
sudo bfgminer --scrypt -o stratum+tcp://URL:PORT -u USERNAME -p PASSWORD --zeus-cc CHIPCOUNT --zeus-clk 328 -S zeus:/dev/ttyUSB0
Where:
URL:PORT is the address and port of the pool you wih to use. Now I won't suggest a pool. I will leave that decision up to you. If you do wish to mine DOGE take a look at this site for a list of pools and comparisons.
USERNAME this is the username you use on the pool. Every pool is different. Check your pool's website for details. PASSWORD same as above. Specific to your pool, not every pool requires one.
CHIPCOUNT this is specific to which ASIC you are using.
For GAWMiner ASIC's:
  • War Machine: 256
  • Falcon: 128
  • Black Widow: 64
  • Fury: 6
For ZeusMiner ASIC's:
  • Blizzard: 6
  • Cyclone: 96
  • Hurricane X2: 48
  • Hurricane X3: 64
  • Thunder X2: 96
  • Thunder X3: 128
Now to make sure you don't stop mining when you exit ssh or terminal. Press:
ctrl + a + d
To come back to the BFGMiner screen simply run:
screen -r miner
You're done!!

Start on Boot

First off you will want to make sure you have BFGMiner running correctly. Ensure you have the miners set up properly and your pool correctly configured.
Start a BFGMiner instance, detailed above.
Once the instance has started and you are happy with how everything is working press "s" on your keyboard to enter the settings menu.
Now press the "w" key. Don't press enter. We want to specify where our config will go. Type:
/home/USERNAME/bfgminer.conf
Substitute USERNAME for your user. On a standard RPI install its pi. On ubuntu it's what you set during the instillation.
Now press the enter key to return back to the main BFGMiner screen. Press "q" on your keyboard to exit BFGMiner. You should now be back in the command line.
Now we want to edit a file called rc.local. Any commands in this file will be executed on boot.
sudo nano /etc/rc.local
Depending on your system this file may already contain some commands. Be careful not to delete them.
After the last command and before "exit 0" type the following on one line:
sudo -u USERNAME screen -d -m sudo bfgminer --config /home/USERNAME/bfgminer.conf
Where USERNAME = your username
Hit ctrl + x then y to save and exit nano.
The above command will create a new screen session and run bfgminer using the config we created earlier. All while as our username so that we can easily reattach.
Lets reboot to ensure it is working correctly:
sudo reboot
Once rebooted and logged in, show all running screen sessions:
screen -ls
Reattach to the session. You only need to use the numbers before the first dot.
e.g Mine looks like: 2480..hostname (13/07/14 12:02:09) (Detached). So I type:
screen -r 2480
Verify everything worked as expected. Then ctrl + a + d to exit.
You have now setup BFGMiner to restart on reboot.

Power Failure

If you are using a Raspberry Pi and it loses power it will automatically reboot on receiving power again.
For standard desktop PCs there is an option in some BIOS/UEFI to turn the computer on when it receives power. Consult your motherboard's manual and manufacturer's website.

Here is where I got my info from.
And of course /dogemining

Wrap Up

Congrats you've done it. You have managed to successfully get your shiny new asic mining away.
I do plan to make another guide detailing how to setup and use StarMiner a ready to go RPi mining distro.
So I hope this is helpful for you guys. I have seen lots of posts asking the exact same questions again and again and I have tried to answer these as best I can. I am still learning about this stuff so if there is something I have missed or a mistake I have made please tell me.
Anyway good luck. And I'll see you at the moon.
Cheers Frogsiedoodle
Edit 1: Layout and formatting.
Edit 2: Added instructions for screen which I initially forgot.
Edit 3: Removed 1 unneeded dependency

Trying to set up RPi to mine bitcoin using Block Erupters, but nothing seems to be working correctly

Hey guys, so I'm trying to use my RPi (B+ model) to set up a rudimentary bitcoin mining rig, but nothing seems to work correctly. I've tried using cgminer on Raspbian Jessie, but cgminer seems to refuse to use the miner. Nothing shows up when I check my hash rate on Slushpool's website, the current pool I'm using. I have another microSD that I set up with minepeon, but every time I try to plug in my Block erupter (which is a dualminer Litecoin/Bitcoin miner), it keeps telling me that I don't have permissions to access the USB port that they are plugged into. I've googled various things and I keep getting closer to it actually working, but it still isn't showing any hash rate. Anyone tried something similar and had problems?
tl;dr: Using RPi B+ to mine via ASIC block erupters, both with Raspbian Jessie and cgminer, and with minepeon, neither work correctly. Help?

mining with ATI Radeon HD 5700 series

I have been getting into the bitcoin frenzy finally and started looking into ways in which I can start out. I'm not the usual n00b since I have everything up and working. Only thing that I am having problems with are the performance issues. I have my Catalyst drivers installed and running and the Radeon is working like it should but at a lower speed than I expected from what I have read about others using this same card series. When I use guiminer with the slush pool, I get at least 80 kH/s, when mining litecoin with guiminer scrypt, I get more performance at 200 kH/s. both less than what I had expected. This is all in windows. When I give it a go in Linux with cgminer, the program doesn't even see the card, apparently it seems to be checking the usb hub instead of rhe PCI and PCI express ports. Is there a way to make cgminer look into the pci slots instead of only checking the usb ports. I can always use a USB asic miner from a company like butterfly labs but I have heard not only negative feedback about not only the performance but also the price in which they are sold for and how it's time consuming to get it to pay you back the extremely large amount of money that you spent on them in the first place. Can I get my Radeon card to mine faster in windows, and how can I get it recognized in Linux by cgminer. This is getting really frustrating, and bitcoin jobs are more competitive than actual jobs. If it's relavent, I only get internet bandwith at 2Mb/s which i think is a major contributing factor but I've been told it isn't.

The Anatomy of Genesis Mining Rig

Crypto mania is taking the world by storm! From reaching a combined $600 billion market cap, to Bitcoin trading at $20k on some exchanges, there seems to be no stopping the rise of digital currencies.
There are many ways to cash in on the potential that crypto has to offer, one of them being mining. This is the process where each transaction or record on the blockchain network is verified. As a reward for their contribution to the network, the miners receive freshly generated cryptocoins.
The cryptocurrency mining process is extremely processor as well as power intensive, and can get expensive if tried individually at home. Not to mention, the mining process requires specialized hardware, which has to be set up by oneself along with the power supply to feed the hardware. Genesis Mining steps in here to make the whole process easier, allowing interested cryptocurrency community members to be part of the mining community without going through any of these hassles. On a mission to “democratize mining”, the company is providing accessible and affordable cryptocurrency mining solution to the masses.
Genesis Mining provides cloud-based mining services to small- and large-scale investors. Their mining farms already have all of the equipment set up. In fact, the platform has the best Bitcoin and Altcoin-mining hardware and software available and running already.
The representatives of Genesis Mining have recently taken an initiative through their “EvolveWithUs” campaign to explain cryptocurrency mining and their services in the sector to the general public to increase awareness about the process and the company’s offering.
What is a Mining Rig?
Stefan Schindler, CTO representing Genesis Mining offers a simple definition for the most crucial hardware in the mining operation by saying,
“A mining rig is basically a computer, but is stripped down to the minimum in terms of computing, and up to the maximum in terms of mining.”
The Evolution of Mining
Mining had previously been done on a computer’s processor. However, as the industry grew, so did its mining requirements. Processor mining took an enormous amount of power, and an alternative was eventually adopted — Graphic cards. Graphics Cards or GPUs, proved to be more efficient at processing transactions, and didn’t use nearly as much power, resulting in a classic ‘work smarter, not harder’ approach. Since then the industry has advanced, creating specialized hardware called ASIC miners. However, GPUs still play a vital role in mining some of the popular alternative cryptocurrencies (Altcoins) in the market.
The Structure of a Mining Rig
In appearance, it looks like your average computer mainboard. The key difference is that is filled with lots of GPUs. The USB port contains USBs holding the actual mining software, which is not stored on the processor. It also has plenty of connecting cables to make everything run.
GPU processing
In the case of Genesis Mining, their specialized mining rigs can hold about six GPUs each. The mainboards available on the market do not have the internal space or slots for all of these GPUs that goes into Genesis Mining’s version of mining hardware. This is where PCI risers come in, which are extension cables that allow the mainboard to be fitted with many GPUs. These risers also help with even heat distribution so that the rig doesn’t overheat.
The power supply unit is also fitted with a strong cable, and powers all of the GPUs and the mainboard.
The company manufactures, stores and operates the mining rings at their mining farms in Iceland and other locations. These equipment can be quickly and efficiently assembled and are completely mobile for added convenience.

Raspberry Pi + ASIC defcoin mining guide

Want to get started mining defcoin with an ASIC and a Raspberry Pi? Does 360 KH/s of mining power sound appealing? Here’s how to do it.
https://pbs.twimg.com/media/Blpj8IvCcAEIStY.jpg
1) Hardware List
-Raspberry Pi Model B
--SD Card
--Micro USB power supply
--Ethernet cable
-Gridseed ASIC
--12V power supply (5.5mm/2.5mm barrel connector)
--USB to Mini USB data cable
The main component is the Gridseed ASIC, which will be doing the Scrypt calculations. The Raspberry Pi will be used as the controller for the ASIC, and will be doing the communication with the mining pool. If you’re not familiar with the term, an ASIC is an Application-Specific Integrated Circuit - basically a chip with a single purpose, like mining crypto currency. Using an ASIC will allow us to mine more efficiently than we would be able to with general purpose hardware.
The ASIC that I’m using is a “300+ KH/s Single Gridseed ASIC Miner”. It looks like a CPU heatsink with a fan attached. There is actually a circuit board with 5 ASIC chips sandwiched between two halves of this heatsink, and has a mini USB connector and a power connector sticking out the side. There are a few places where you can buy these. I bought mine at GAWMiners.com for $130. That was the lowest price that I could find, and I had a good experience buying from them. Use this link, and you can get $20 off of a $200 order (and give me some referral points :-)) GAWMiners. You can also find other vendors by searching for “Gridseed ASIC”. You’ll need a 12V power supply to power the ASIC, and a USB A to USB Mini B cable to connect the ASIC to the Raspberry Pi. I’m using a 60W power supply, which seems to be working fine for defcoin (Scrypt) mining. These ASICs can also mine Bitcoin at the same time, but you may need a beefier power supply if you want to do that.
The Raspberry Pi can be purchased at any number of places- Amazon, SparkFun, AdaFruit, etc. I’m using the Model B because I had one already, and also because it has a built in ethernet port that will make connecting to the internet easy. Make sure to get an SD Card and a micro USB power adapter to get the Pi up and running too.
2) Software
If you haven’t already, download the defcoin wallet from defcoin.org. If you want to do pooled mining, create an account for one of the defcoin pools, such as redbaron.us or whichever other pool you want to mine. Once you’ve created a pool account, make sure to create a worker too (for MPOS pools, that will be under My Account > My Workers). The password for your worker does not have to be the same as the password for your pool account (and it probably shouldn’t be).
Next, download the latest Raspbian image from raspberrypi.org/downloads/ and install the image to your SD card. Instructions for installing the image can be found here. If you are using the dd method on a Mac, make sure to use /dev/rdiskX instead of /dev/diskX - both will work, but rdiskX is much faster. Once you have the image installed, put the SD card in the Raspberry Pi, connect the Pi to your network, and connect the Pi to your micro USB power adapter to power it on. Next, SSH in to your Raspberry Pi with the default username and password pi/raspberry. I use nMap to find the IP address that has been assigned to my Pi. You can also use an HDMI display and a USB keyboard to log in instead of using SSH. After logging in for the first time, run through the wizard that comes up to configure your Raspberry Pi. The defaults are fine for most things, just make sure that you don’t skip the step to expand the filesystem to use the rest of your SD card. If you don’t expand the filesystem, there won’t be enough space for other software.
Once you have Raspbian installed, and have gotten through all of the first login setup stuff (which will likely end with a reboot), log back in to the Raspberry Pi with the pi user. From the command line, run sudo apt-get update sudo apt-get dist-upgrade
There are some stability issues with USB communication between the Raspberry Pi and the Gridseed ASIC. Enabling SLUB debugging seems to resolve this, at least well enough to prevent the Raspberry Pi from freezing every so often. Open the /boot/cmdline.txt file, and add the following text to the end of the line. Don’t add a new line, just add this to the end. You can use vi, nano, or whatever your favorite text editor is to do this.
slub_debug=FP 
Reboot the Raspberry Pi once you’ve added that flag to your /boot/cmdline.txt file.
sudo shutdown -r now 
Log back in with the pi user once the Raspberry Pi is finished rebooting.
The mining software that we’re going to use is a customized version of cgminer that has support for the Gridseed GC3355 chips that are used in our ASIC. There are a number of different mining programs out there, this is just what has been working the best for me so far. First, install git and dependencies needed to compile cgminer.
sudo apt-get install git build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake 
Next, clone the git repository for cgminer-gc3355
git clone https://github.com/dtbartle/cgminer-gc3355.git 
Next, we’ll build cgminer.
cd cgminer-gc3355 autoreconf -i ./configure --enable-scrypt --enable-gridseed make 
Once the make command finishes, we’re ready to run the mining software. You can also run make install if you want to install the software, but running it out of the build directory works just fine. Plug in the power supply for your ASIC, and connect the ASIC to it. Connect the USB cable to the ASIC and to your Raspberry Pi. Run the mining software by running the following command. The -o option specifies your pool URL, the -u option specifies your username and the workername that you set up for the pool, and the -p option is the password for your worker. There are a couple of options available that are specific to the gridseed ASICs, and those will be placed after --gridseed-options. The freq=850 option sets the clock frequency of the ASIC to 850 MHz. There are other clock options available, but 850 seems to be working best for me. I was getting hardware errors at 900, and a lower average hash rate. I am getting about 360 KH/s with the clock frequency set to 850.
sudo ./cgminer -o stratum+tcp://www.redbaron.us:3333 -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 
This command needs to be run with sudo in order to access the USB hardware. You can also create another user specifically for mining, or grant the pi user the appropriate permissions if you don’t want to run cgminer as root. When you run this command, you should see output from cgminer showing that it is communicating with the mining pool, and something showing your hash rate. If you’ve gotten this far, and you’re seeing output from cgminer showing a hash rate, congratulations, you’re mining defcoins with your ASIC! There are just a couple more steps to do if you want to let your Raspberry Pi and ASIC continue mining without needing you to be logged in.
To keep cgminer running after I log out, I am using nohup. You could also use screen instead of nohup. Create a script (startMiner.sh) by running the following commands.
echo “nohup /home/pi/cgminer-gc3355/cgminer --real-quiet -o stratum+tcp://www.redbaron.us:3333 -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 &” > /home/pi/startMiner.sh chmod a+x /home/pi/startMiner.sh 
If you run this command with sudo startMiner.sh, cgminer will run in the background, and will continue running after you log out. If you want to have this run when your Raspberry Pi boots, modify your /etc/rc.local script so that it executes this startMiner.sh script. Your /etc/rc.local file will end up looking like this:
# Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi /home/pi/startMiner.sh exit 0 
That’s it! You should now have a Raspberry Pi controlling a defcoin mining ASIC, that starts mining as soon as it boots up. For more reading, check out some of the links below.

Frequently Asked Question: What's an ASIC, FPGA?

So you're sick of just mining on your GPU, and not a fan of the electric bill after a month of mining? There has to be a better option out there than your loud GPU in your gaming computer. There is!
Shortly after GPUs became popular for bitcoin mining, enterprising folks started looking at other things they can re-purpose to mine bitcoins more efficiently. Around mid-year 2011, the first devices sprang up that are called FPGAs or Field Programmable Gate Arrays. These are nothing new to the hobbyist community, they've been around for a while for crackers and other security-conscious folks looking at ways to defeat cryptographic locks. Hey! I know something that uses cryptographic calculations to secure its network! BITCOINS! Yep, so some miners developed their own boards and slapped some FPGA chips on them (most commonly the Spartan-6), and wrote specific firmware and "bitstreams" to more efficiently calculate bitcoin hashes. The first generations were sort of slow, but still they had better efficiency than a GPU. Some of the latest generation included the Icarus boards, Cairnsmore, x6500, and ModMiner Quad.
In early 2012(i think my timeline is right), Butterfly Labs(BFL) was selling their own FPGA miner that hashed at 800 Mhash/s using 80 watts and only cost US$600 amazing! These grew very popular, but people could see that FPGAs still weren't the most efficient way to hash their shares. BFL then announced that they would be designing their own chips that would be orders of magnitude faster than anything ever seen. These would be the ASICs (or Application Specific Integrated Circuit)everyone is raving about. ASICs are--as the name implies--specifically designed for one thing, and one thing only. Bitcoins. This is all it can do, and can't really be repurposed like an FPGA to other applications. Who wouldn't want a US$150 "Jalapeno" that hashes at 3.5 GIGAhashes/s using only power from a USB port?? Crazy! So summer 2012, BFL says they will ship before Christmas. Various things happen and we now still don't have any confirmed ship dates from BFL.
A few other companies have sprouted up, ASICminer which I believe is developing their own chips to mine themselves, but in a responsible way as to not threaten the network with a sudden influx of hashing. bASIC was a fiasco that was developed by the creator of the ModMiner Quad(which is actually a fantastic miner, I own one, and love it.) where he took many preorders, promised lots of people amazing ASIC performance, but in early 2013 the stress of the whole endeavour got to him and he gave up, refunded money(I think it's still being refunded now, or maybe it's been cleared up already.)
Avalon is the only company we know has ASIC mining hardware in the wild. It is not certain exactly how many are out there, but they have been confirmed by independent sources. The Avalon units are expensive(75 BTC) and have been in limited production runs (or batches) of a few hundred units that were pre-sold out very quickly.
All of this info is gleaned from the Custom Hardware forum over at bitcointalk.org over the past year or so I've been involved in bitcoin. I may have some facts wrong, but this is the gist of the situation and hopefully gives you an insight on the state of the hardware war against bitcoin
Thanks for reading!

Block erupter issue

I have looked over google for some help but im obviously not looking in the correct places because I did not see what i need. Hopefully someone here can point me in the right direction. Here is whats going on. I started off with 1 asic block erupter (ASICMiner Block Erupter USB 330MH/s Sapphire Miner) and everything was going fine. i added another one to the setup and everything was still going fine. (this is all being done on USB ports that are on the back of my PC, no USB hub, yet) I then aquired an antminer (BITMAIN ANTMINER U2 2Gh/s USB Bitcoin ASIC Miner. Overclockable) and plugged it into my PC as well. I am using BFGminer 3.10.0 currently and everything was running fine. all 3 miners were mining. I went ahead and ordered a usb hub because i figured if i was going to keep adding miners that my computer would not be a good place to put them all. well a day before the hub got here, i noticed that one of the miners (the saphire one) was not mining. i looked at my device manager and only saw 2 of them. so i rebooted, messed around with some different ports but nothing made that one work. i figured it was broken for whatever reason and assumed it was because it wasnt suppose to be on my mother board. thing is, it works on another PC. so i waited for the hub to come in to see if it would work on there but it still does not. Im thinking its a driver issue since its not showing up on this computer but it will on another. Any idea or suggestion on how to get my current PC (windows 8.0) to run it? Should i try a different version of bfgminer, or maybe cgminer? im fairly new to all this so i dont really know where to go with it.

Help with getting things to start mining scrypt currencies (using raspberry pi 2 , gridseed asic miner , & cgminer) . . .

Here's what I have & will be using (I already have the cables & power) :
raspberry pi 2 Gridseed ASIC Miner for Litecoin and Bitcoin Mining --- 4 of these cgminer
[ I followed this example for setting things up : https://www.reddit.com/defcoin/comments/23nvs1/raspberry_pi_asic_defcoin_mining_guide/ it is my understanding that any altcoin you wish to setup mining for , is done in this similar fashion ]
I want to do scrypt cryptocurrency mining , I just want to understand how this is done ....
( I know there's a lot of tutorials out there & great vids , and I've done a lot of reading on all this matter , but I can't seem to get things working right , please help / advise )
Questions:
  1. if I solo mine , what is the correct port # to use here (and is the below command formatted correctly more-or-less) :
sudo ./cgminer -o stratum+tcp:localhost:#### -u Username.Workername -p yourworkerpassword --gridseed-options freq=850
( I understand I need to create my own pool , a pool of 1 , is considered to be solo-mining , correct ? How do I do this ? )
  1. also , before I can solo-mine , I need to have downloaded & install the wallet for the cryptocurrency I am going to mine , correct ? And I understand there is some kind of Config files relevant that I should modify accordingly to set things up with my mining solo , right ? How is it done & where do I find this config files ??
  2. I tried connecting my 4 gridseed(s) to my raspberry pi 2 , via the 4 usb ports it has , but it seems like it can't handle the 4 of them , so I have to deal with only using 2 of the gridseed(s) connected to my raspberry pi 2 at a time .... does this seem right to you ? And so , what work around do I have for this poroblem , I want to use all 4 of these gridseeds connected to my raspberry pi 2 ,,, I'm guess a usb hub is needed for this right ?
THANKS IN ADVANCE FOR YOUR HELP AND GUIDANCE !!!

Block Erupter Sapphire not working with CGMiner

Hi,
I'm having trouble getting my Block Erupter to mine for me. I'm running Vista 32 bit (ugh) with CGMiner 3.3.0. I think I have the drivers installed and I can see my device on COM3. I'm pretty much using a shortcut with the script below:
C:\cgminer\cgminer-nogpu.exe -o [pool]:[port] -u [username].[worker] -p [password] --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3
It just opens and crashes, though. When I try to run it in a command prompt it tells me
USB init, open device failed, err -12, you need to install a WinUSB driver for - AMU device 1:1 Icarus detect (1:1) failed to initialise (incorrect device?) No devices detected! Waiting for USB hotplug devices or press q to quit
I'm using this driver.
Where am I going wrong?
/edit: Basically I'm following this guide because it's the only one I can find that offers help.
/edit edit: installed zadig and replaced the driver, and removed the -S //./COM3, and now I just get "No devices detected!" It's progress, but still not working. :(
/update 3: Switched to bfgminer and that seems to be working. Oddly enough, I'm showing 3 sets of hashes. it shows up something like 520/436/600Mh/s. I'm a little noobish yet with mining, so I'm not sure what this means. I only have one GPU and one Erupter. Why would I show 3 sets that high?
/update 4: Thanks so much for your help! I now have my Block Erupter up and running alongside my GPU. Vista administrator mode is what finally got it working for me.
