PCI-e to USB Card Passthrough Suggestions

My POS motherboard only has ONE usb controller, which means I'm unable to pass it through to my Windows gaming VM. I need to do this as my Xbox wireless adapter is really wonky with just USB passthrough, and the only way to get around this is to passthrough an entire USB controller. Pretty sure this is a KVM issue as I've never had any issues passing through USB devices on ESXi.
I have an mATX build with a huge graphics card, so my PCIe x2 slots are blocked off, but I managed to use one of those bitcoin mining rig extender cables to "breakout" the slot. My inelegant plan is to just get a PCIE to USB card and mount it externally.
Anyone have any suggestions for a good card that works with unRAID? I see a lot of cheap options on eBay/Amazon. Used server grade cards would be ideal.
I'm even open to alternate suggestions. Things I've thought about:

UpgradeMeAPC? Hoping to (re)build a "do-everything" PC; what devices might I need, and need to upgrade?

I already have a desktop PC, but I am planning a summer project with my roommates to upgrade some of it and have a wall-mounted, water-cooled, monster-of-a-machine that essentially "does everything," within relatively-sane reason. The wall mounting is completely up to us and still in the planning stages, but the advantage here is that it allows us to craft a case that can potentially fit all kinds of neat things in/on it, from the watercooling rig we're looking into to the buttload of additional drives (hard drives and otherwise) we may want to stick onto it.

"Does everything" essentially means that we'd be hoping to be able to do effectively anything from game, burn CD/DVD/Blu-Ray discs, read ZIP (yep, we still have some of those around) and 5.5"/3.25" disks, "professionally" (one of us is a graphic designer for a local magazine, so there's that) edit photos and video, record home-studio-quality sound (I record audiobooks for my students, for example), maybe even mine bitcoin (lol?) and more.

Some of the parts I have already include:
- GeForce GTX 1080 G1 ( https://www.amazon.com/gp/product/B01GJEE9BG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , probably need a better one or a second one if we do the bitcoin....erm...thing. This is probably the part I'm least willing to upgrade, as they tend to be the most expensive, but I'm still all ears)
- Intel Core i5 660K 3.5GHz CPU ( https://www.amazon.com/gp/product/B012M8M7TY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , could maybe upgrade)
- Corsair Vengeance LPX 16GB DDR4 D2666MHz C16 memory ( https://www.amazon.com/gp/product/B0123ZC44Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , definitely open to upgrading this)
- ASUS Z170-A Mainboard ( https://www.amazon.com/gp/product/B012NH05UW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1, likely need to update this based on our "needs" for the build we're hoping to accomplish )
- FocusRite Scarlett Solo USB Audio Interface ( https://www.amazon.com/gp/product/B01E6T56CM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 )
- Behringer B-1 Condenser Microphone ( https://www.amazon.com/gp/product/B0002KZAK8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , also have a pretty nice stand and filters for it but am open to further suggestions. Not looking to upgrade the microphone itself but if you want to recommend a nice desktop stand for it, or cables, or pop filters, or whatever, I'm all ears!)
- 5-port PCI USB ( https://www.amazon.com/gp/product/B01LZWC7TL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1, willing to upgrade if this one happens to be a piece of junk )
It also has two internal hard drives (I can upgrade these how/whenever, doesn't really matter right now but I'm looking for high-capacity recommendations), and a whole lot of USB interfacing (keyboard and mouse are separate, microphone is another, have an external blu-ray drive, a Bluetooth USB dongle, a Playstation DexDrive, and more).
Recommendations for layouts are absolutely welcome (like I said, we're still just planning right now) and for other components like fans and watercooling components are also welcome and appreciated. We're not flying blind, but we ARE flying with essentially just guidance from Google and what other subreddits turn up.

I'm not super sure where or how to start, since the PC I have now is the first PC I've built since 2000, so any help is appreciated!

Need some troubleshooting help! Riser 008s and R3c

This project isn't for gpu mining but I know these risers are mainly used for this purpose so I thought I might get some good feedback here. My project is that I have an itx board with a single x16 pcie slot. It also has 3 m.2 pcie gen3 x4 slots. I have one free m.2 slot and wanted to convert that to x16 via riser. I wanted a 2nd low power silent gpu added to the rig. I went with the fanless msi 1030. It has a max draw of ~30w so I figured sata power would be safe. I purchased this and this to test with. Neither work!! So it must be something on my end?? The first part is fairly standard, the difference being I'm going to a m.2 slot where most of you are coming from x1 or x4. "In theory" this should just work! I'll start with the 2nd part since it's very simple: m.2 connector -> x16 socket + sata power. I hooked this up, seated the gpu and booted up. Nothing. Not even bios. I pulled the gpu and booted. Bios worked and booted up (running a 1080ti direct on the board). Installed the gpu back and nothing. I bought the 1030 used so I pulled the 1080ti and installed the 1030 direct to the mb. Works! So then I thought maybe the riser is bad or that sata power is insufficient seeing that most gpus would also have 6+8pin direct whereas mine has no external power. So I swapped risers out. This time the 008s with additional power connectors. Exact same thing. First I powered via pci only. Then sata+pci. And finally sata+pci+molex. In all situations the red led lit up. In all situations if I do not have the gpu plugged in it boots up fine. The strange thing is I never get into bios. No speaker or post lcd on this board so my troubleshooting is limited. And to note I test both gpu hdmi ports just to make sure one vs the other was set to primary. I got lazy and just looked at my mouse to light up to see if it booted. The mouse stayed dark, implying it never posted. Any help would be greatly appreciated! solved I have two m.2. ports which are pcie only. I have 1 port that is pcie/sata. the suggestion by u/sqrtlurface was to use the pcie/sata port and now the 1030 is being recognized in both linux and windows.

How To Invest in Cryptocurrencies: The Ultimate Beginners Guide

All statements are based on the author’s experiences. I take pride in informing the public and helping as many as I can through sharing my experiences with my readers. That said, no one except you can take responsibility for your Cryptocurrency Investing decisions, so do think it through before investing.
If you would like to learn more about the techlogogy behind cryptocurrencies, please check out our blockchain courses on crypto.
When I first started taking an interest in cryptocurrency I thought I was so lost in this huge sea of unknowns. Where do I start? What are the useful keywords to look up and keep in mind? What are the available helpful resources? This cryptocurrency investing guide is written so that in just 20 minutes, you would have a sense of what to expect of your upcoming crypto journey, and how to best go about starting it. Enjoy it, it might just be the most exhilarating ride of your life.

Rise of the Cryptocurrencies
As the tech literacy of the population increases, acceptance of crypto as a legitimate store of value follows, and it boomed. Titles along the lines of ‘Bitcoin price hits new all-time high’ and ‘Ethereum price surges’ are starting to perforate the general public’s news feed. What we know for sure is that people who were once skeptical of Bitcoin and the technology behind it are slowly understanding and getting increasingly involved with crypto. As at the time of writing, the market cap of the entire crypto space is at 30.9 billion USD. It was 20 billion just four months ago. What would it be four months from now?
Current Makeup of the Cryptocurrency Space
You would have heard of Bitcoin and the ‘altcoins.’ How this naming convention started was because back in the days of 2011, forks of Bitcoin appeared in the markets. The forks, or clones, each aspire to serve a niche area, aiming to be ‘better’ than Bitcoin. Since then countless new crypto has emerged, eroding away Bitcoin’s crypto market cap dominance. These altcoins are gaining market share at an alarming speed. Ten times or more growth has been observed in a time span as short as six weeks (see PIVX, an altcoin).
Cryptocurrency, Stocks, and Fiat
The currencies we know are referred to as ‘fiat’ by the cryptocurrency community. Although having ‘currency’ in its name, cryptocurrencies share more similarities with stocks than currencies. When you purchase some cryptocurrency, you are in fact buying some tech stock, a part of the blockchain and a piece of the network.
Cryptocurrency Exchanges
The most common place where people buy and trade cryptocurrency is on the exchanges. Exchanges are places where you may buy and sell your crypto, using fiat. There are multiple measures to judge the reliability and quality of an exchange, such as liquidity, spread, fees, purchase and withdrawal limits, trading volume, security, insurance, user-friendliness. Out of all these, I find Coinbase as the best exchange hands down. It has a beginner-friendly user interface, and an unbeatable 100% crypto insurance.
After setting up an intermediary bank account and verifying your details with Coinbase, you are only five simple steps away from a Bitcoin purchase:
  1. Access the ‘Buy/Sell Bitcoin’ tab
  2. Select the payment method using the drop-down menu
  3. Enter the desired amount
  4. Click ‘Buy Bitcoin Instantly.’
  5. View your credited Bitcoins on your dashboard
When you get acquainted with buying crypto and start to itch for some crypto trading (e.g. BTC/ETH), simply perform an instant transfer from Coinbase to GDAX free of charge and start trading. Think of Coinbase as the place to conveniently buy and store your crypto and GDAX as your margin trading platform. Transfers between the two are instant and free.
As you slowly get familiar with other currencies, you might want to have the option of investing in them. Bittrex and Polo are two exchanges that offer a wide selection range.
When signing up on these exchanges for the first time, do make it a point to verify your account with the required documents early, as you do not want to be caught in the middle of some tedious and slow admin work when the trading opportunity comes. Verification on these exchanges may take days, and purchase/withdraw limits may only increase gradually as you trade.
An additional point to note: if you are using a currency other than USD, do check out the exchange’s ease of funding and withdrawal. You do not want your exchange to come into fiat withdrawal problems like Bitfinex did recently.
Cryptocurrency Wallets
Exchanges have inbuilt online wallets to keep the cryptocurrency you purchased. However, for those who heard of the Mt. Gox hack, you might feel uneasy to put on an exchange. If you do not wish to keep your crypto holdings on the exchange, you have the option to either use a paper wallet service like myetherwallet.com or spend 99 USD on a hardware wallet like KeepKey. Both serve the purpose of removing platform risk, at the cost of taking up the responsibility of keeping your cryptocurrency safe.
To transfer your crypto from exchanges to your hardware wallet for long term storage, simply follow these steps, using Coinbase and KeepKey as an example:
  1. Plug in your KeepKey USB cable
  2. Open your KeepKey Client (on Google Chrome under Apps)
  3. Find your wallet address on the KeepKey Client UI
  4. Access Coinbase ‘Send/Request’ tab and input your KeepKey wallet address
  5. Confirm amount and click ‘Send Funds’
Take note to first send a tiny amount (e.g. 0.0001 BTC) for testing before sending the bulk, lest an error occurred and the transfer amount is lost. A small network transfer fee might be charged.
Personally, I own a hardware wallet, as I love the feeling of a having around a tangible reminder of my crypto holdings. Also, the hardware wallet’s user interface makes it easy to keep multiple coins, which is especially handy when you participate in ICOs (Initial Coin Offering) in the future.

Cryptocurrency as a Percentage of Your Investment Portfolio

This part will be wildly subjective. Crypto has the potential to realize many ‘rags to riches’ stories, but its volatility makes it unpredictable. As a precaution, the money you put in crypto should be money that you are fine with losing. I cannot emphasize the importance of this as we often underestimate how the volatility affects our emotional capacities. The upside is huge, but it comes with lots of risks and, if I may put it, emotional torment.
A conservative portfolio I would suggest is as follows:
< 30 years old (max) 30% Crypto, 50% Traditional Investments
30 – 40 years old (max) 20% Crypto, 60% Traditional Investments
> 40 years old (max) 10% Crypto, 70% Traditional Investments
This is not meant to be age discriminatory but considers the fact that one takes up more financial responsibilities (mortgage, family) as he grows older.
Within the designated crypto share of your portfolio, you may diversify your coins based on your risk appetite.

Show Me the Money! Cryptocurrency Investing

Now, this is where it gets exciting.
How do we pick the winner? How do we avoid picking the loser?
Note that crypto is now in a huge bull market and anything could rise over time. Also, do not dismiss the possibility that we may be in a bubble like the-dot-com boom back in 2000. Still, ask yourself these questions before you decide to invest in a coin:
Short Term Trading with Margin
Once you get familiarized with crypto, you may want to trade on your ‘stash’ in hopes of increasing it. For the experienced forex traders, this is nothing new. But for the new crypto investor, you may want to brief up on how to make a leveraged trade.
Short-term trading takes advantages of incoming news to make a quick buck. If you foresee good news from an upcoming release of a coin, you may want to open a long and see how it goes. Remember, buy the rumor, sell the news; act fast and be daring if you wish to make a profit with short term trading.
Mining
For those who are more comfortable with a predictable form of reward, mining is the way. Mining involves setting up of a rig, consisting of GPUs or CPUs and an investment in the electricity. Mining is only possible on cryptocurrencies that follow the Proof of Work protocol. It takes some effort to setup and gets things running, but it is attractive as a long-term passive income as long as you frontload the work.
Staking
Staking is the Proof of Stake version of ‘mining.’ Think of this as making dividends on your stock. The reward rate and staking method differ greatly among Proof of Stake coins, but in general, it takes less effort as compared to mining.
Arbitraging
As you get a hand in multiple exchanges, you may wish to buy from one exchange and sell on another to make ‘arbitrage’ gains when you spot an arbitraging opportunity. Take note of two things if you wish to do so: remember to factor in fees, and remember that the price could change when you are transferring your coin between exchanges, especially during volatile times. USD tends to be liquid so this happens less for it, but for other currencies such as CAD (Canadian dollar) and SGD (Singapore dollar), there may exist more arbitraging opportunities to exploit.
That’s about all I have, for now, invest smart and most importantly, don’t forget to have fun!

How to get $100 million in VC funding to build an industry that makes $300 million profit without spending a dime

Yesterday I received an unexpected gift: a link to a copy of the slides of the presentation that 21inc gave to investors, apparently between October and December 2014, when they were still calling themselves "21E6".
(The sender asked to remain anonymous, and I am not sure about the copyright status of the file; so I would rather not repost it here yet. But it seems that several other people, including some of the 21inc competitors, have got a copy too; so anyone who is really interested can probably get it too.)
The slides don't have much new factual information, and basically confirm what we already guessed about the 21inc business plans. But they show that we severely underestimated their chutzpah and hype. Here are some random highlights (as far as I can decipher from the slides):
They had three relevant mining rig designs in the plans, that would require funding:
Codename Qty TH/s kW Cost Deploy Turnoff Profit($) --------------- ---- ---- --- ---- ------------ ----------- ----------- CyrusOne(v2), 7904 2.0 1.3 --- (already on) Apr 2015 ~23,000,000 IO(v1v3) 3250 5.2 1.3 2000 Jan 2015 Aug 2016 ~24,000,000 Brownfield(v3) 1900 5.5 1.3 2450 Mar 2015 > Nov 2017 ~20,000,000 
The "TH/s", "Cost", and "kW" columns are per "system", i.e. a mining unit containing many chips. The last column is the expected profit to be made from each set of mining hardware over its expected lifetime. (The slides have some other details that do not seem to be important.)
The first line is the hardware that they were mining with at the time of the presentation; that must be why the "Cost" (as far as investors are concerned) is given as zero.
The second line seems to be an upgrade of their previous mining hardware from v1 chips (which gave 2.7 PH/s total at the time) to v3 chips (which would give 17 PH/s) .
In reality, we have seen that their share of hashpower dwindled through all of 2015, and (AFAIK) they haven't mined a single block in the last six months. Were they still mining with CyrusOne on extra-life, or were they using the upgraded IO which was turned off prematurely? What happened to Brownfield?
However, their mining operations were secondary; the meat of their plan was the embedded chip, called BitSplit at the time.
The BitSPlit chip (as we suspected) was hard-wired to send 75% of the block reward to the 21inc wallet, whose address was burned in the silicon, and 25% to the user's wallet.
By my calculations, assuming 50 GH/s and no increase in the difficulty, the BitSplit would mine one block in 570 years, on average, and collect less than 2 BTC of reward in that time. So, of course, the chip was hard-wired to mine into a pool run by 21inc, that would spread the user's 25% of those 2 BTC (expected) into a daily regular trickle of a couple thousand satoshis. Their own mining operations would provide the BTC needed for the pool payouts of all the millions of chips that they expected to be running out there.
They projected to release 3 versions:
Model Qty GH/s W Cost Deploy Profit($) --------------- ---------- ---- -- ---- ------------ ------------ USB hub-charger 250,000 38 15 $35 Mar 2015 ~8,000,000 Embedded chip 1,000,000 63 15 $8 Aug 2015 ~103,000,000 BitSplit Inside 10,000,000 20 5 $0 Oct 2015 ~292,000,000 
The "Qty" is the expected number of units sold. The last column, IIUC, is the profit that 21inc expected to make from the 75% cut of the BTC produced by all the chips, over their expected lifetime.
In the above "USB hub-charger" model was a USB charging unit, roughly 3 x 2 x 1 inches, with 2 USB outputs and a mining chip inside, produced by 21inc themselves "to seed the market".
The second line, which I called "Embedded chip", seems to refer to discrete BitSplit chips provided by 21inc and included in consumer devices (like routers etc.) by OEM manufacturers.
The "BitSplit Inside" model would be the BitSplit integrated into the chipsets of other manufacturers, and manufactured by them. Its cost is listed as "$0" (for 21inc) because they expected those manufacturers to shoulder the cost of manufacturing and integrating the mining chip.
Apparently the market-seeding "USB hub-charger" was later replaced by the "Bitcoin Computer" (aka the PiTato). In one slide it is called "multifunctional BitSplit device", and depicted as a sleek shiny black box, the size of a cigarette pack, with a power cable and 2-3 USB or similar outputs. If that is supposed to be the PiTato, presumably they had not yet realized that a 15 w computer would need a cooling fan with a miniature wind tunnel on top.
In the last two entries, the manufacturers (not the device owners!) would be rewarded with the 25% slice of the BTC mined by those embedded chips. As an example, the slides say that a manufacturer who produced one quarter of the embedded BitSplits would get the 25% cut on the BTC yield of those chips, that was estimated to be between 2 and 4 million dollars per year of revenue in 2015--2018. Those numbers are based on the following predicted mean BTC prices: $350 for 2015, $1000 for 2016, $2200 for 2017, and $5500 for 2018.
So, their main business plan was fantastic: the OEM and chipset makers would pay the costs of producing and integrating the chips, the consumers would pay the cost of operating them, and 21inc would get 75% of all BTC mined by them, expected to be worth 400 million dollars.
It makes sense to invest 100 million in that plan, right?

Repost - I hate my Fucking Mining rig! (Not really)(Long)

Wanted to write a short write up on my journey of Crypto mining for some of the newer people and people who want to get into it. Not trying to discourage anyone from starting, but want to show the progression of a newbie.
So I am a good with computers and learned of Bitcoin when it was about $7 a coin. Laughed at the idea of some computer doing some math and getting some BS currency. Million dollar mistake on my part, but hindsight is always 20/20.
Anyways, Learned about ethereum in May. Bought some at around $180 and bought all the way up to $330. Now to the mining rig. Ran all of the calculations and with a 180 hashrate and 900 watts I was gonna get 6-7 Eth per month. Shit was gonna be profitable in under 3 months. I was gonna be a fucking crypto allstar and be rich as fuck!
Bought all of my parts literally the day before they were nonexistent. Literally bought the last RX480's from Amazon. Here is a list of my parts.
Asrock board Pentium dual core processor 4 Gb of ram 128 gb SSD 1200 watt Rosewill PSU 6 Sata to Molex PCI Risers (Junk) 6 RX480's - 2 Asus Strix, 4 Gigabyte Total cost - Roughly $2,500 (Pennies compared to my future ROI)
Please keep in mind that I am not posting every single miner issue that I ran into such as fucking with Wattman for a few weeks before learning about Trixx and Afterburner.
I've built computers before, so that part wasn't hard. Set everything up and get windows 10 running.
Problem 1 - Computer doesn't see all of the cards. Had to run the drivers a few times and tweak some shit, but got all 6 cards seen.
Miner hurdle (See what I did there) but off to the races. Let's get this bitch running so I can begin planning my retirement.
Get Claymore running, Got Trixx to overclock. Ran my cards at -96, 1200, 2200 fans at 85% (Cause I'm cool like that.) Major stability issues from the start. 1 card (Asus) would crash all the time. Didn't know about the watch dog feature in claymore that would restart my rig when a card crashed. Great feature but my computer would go into this state of having power, but not loading the operating system. Even if it did restart, most of the time claymore would get stuck right before setting the dag's and would just lock up. (Claymore program is awesome by the way, this was my rigs fault)
Could not get this fucking Asus card to stop crashing, even on stock settings. Sent the bitch back RMA style. Asus said something was wrong and sent me a new one.
Awesome, lets get this bitch running. I need to start looking at sick houses in Costa Rica to move to once I am rich as Fuck!
New card makes things better for a few days. Not 100% stable but better. Go to vegas for a driving thing (Race cars - Future rich guy stuff) and this mechanical demon starts crashing every few hours. Luckily I had Google remote desktop installed so I could log on and restart it or change settings in Trixx. Had to have my GF unplug it and plug it in a few times.
Get back home, fuck with this thing but still random crashes on random cards. Decide it is the PCI risers. Contact seller who will send me some more for free. Slow boat from china took two weeks to get them. They arrive but still some of them are bad. Can't seem to piece together 6 good ones.
Did some research online (Ethereum Forum and Reddit) and decided to get some new style of risers V007 6 Pin to Sata ($70) and they take a month to get here. Plug them all in and they seem to be working much better. Decent stability, But I ain't got time for fucking stock bios. Let's ramp these bitches up and get 32 MHs per card at 600 watts from the wall!
Actually flashing the bios was pretty easy. Thank you 6 pound 9 ounce baby jesus! Long story short had some major stability issues and bounced around with some different timing straps before finding the right ones. (Uber 3.1 for Samsung memory)
So now that we've got some good hash speeds and decent stability let's ramp this private ATM up a little bit by dual mining some Decred. Get dual mining up and running. go to sleep. Wake up the next morning expecting to see myself on the top 100 forbes list. look at my mining rig stats on my phone and see that it died roughly and hour after I went to sleep. Walked toward my rig on the red carpet I had just installed and saw that it was off. Flicked on the light to check it out. No light, WTF? Well I'll be god damned, no power in this whole fucking room. Checked my breakers and sure enough this metal motherfucker tripped my breaker.
No worries though. I'm smart as fuck. I'll just undervolt the shit out of it to get the power down. No way in hell I am just mining ether. I'm going balls to the wall!
As you can expect I had many days of stability issues and tripped breakers. But fuck it, I have homeowners insurance. Burning it to the ground will be covered. (Didn't happen)
My surge protector must be maxed out. Let's buy a bigger one ($25). Same issues.
Fuck Decred, I'll mine SIA, less power. Damn I'm smart.
Rig is more stable with Sia and no tripped breakers. Family medical emergency, have to fly north for a few days. But my rig has been fairly stable and I've got remote desktop if anything goes wrong.
Arrive at airport, check mining stats, rig is down. No worries remote desktop. FUCK, not responsive, no way to remote into the rig and no way to remotely power it off and on.
Lost 4 days of mining. But no worries the difficulty is only, Holy shit that's high! But the price of Ether will make up for it. Ether crashed to the $200's. Oh well, maybe a 10 room house in Costa instead of a 12. No sweat.
Get back to my house and this whore of a machine is just sitting there in a computer coma. It's on but it's not. LED lights glaring at me like "Fuck you human, I ain't doing your stupid math problems!" Fuck you machine, I'm your master. You will do my math problems and you will fucking like it.
My AMD Drivers seem to disappear and the computer goes into a coma like state. Someone on Reddit suggested using the 16.9.2 drivers. Installed and they worked better.
Still random crashing. This shitty PSU must be maxed out. Fuck you PSU, I'm getting you a little brother (EVGA 750 gold $120.)
What do you mean you have to jerry rig a second PSU so it starts without being connected to a motherboard? 2 more hours of my life wasted.
But finally some stability. On my way to being fucking rich. I start looking at people in bentley's and can only laugh. You dumb fuck, I'm gonna be way richer then you. Gonna get a Bugatti for each day of the week.
Damn this difficulty is a bitch. Fuck you Genesis Mining and your pallets of GPU's. You're killing me smalls!
But anyway, on my way to rolling around in my fuck you money!
Fuck you dag file 135, you're killing my future millions. Fuck you dag 138, you dropped me to 167 mhs.
Thank god AMD was there to save my ass with their dope ass blockchain drivers.
download, run DDU, Restart, install drivers, restart, run pixel patch, restart. Perfect, I'm in the money now! I can taste the caviar and champagne already.
Now my cards only run 4 Mhs each. WTF? Try a bunch of the other new drivers. Same shit. Roll back to 16.9.2 and they run fine, just at 167 instead of 180.
Someone on a forum said he had the same issue and did a fresh install of windows 10 and it worked.
So I'll just reformat my SSD (Windows wouldn't do a fresh install within the operating system. Fuck you Bill Gates! Gonna buy you once I get this thing running at 180.)
Format SSD, plug back in, throw in my gangster ass boot USB drive. Ramdisk error. Fuck you Bill Gates! Reformat SSD multiple times, lots of forum reading. Install windows from another computer through command prompt (I'm a coder now as well.) This shit has got to work, I did it in command prompt bitches!
Same fucking error. Now down to an 8 bedroom house in Costa and only 6 Bugattis.
Let's try unplugging my 6 cards and see if that works. Thank you 6 pound 9 ounce baby jesus. Windows installed.
New drivers work and I'm back at 180! Raking in the cash now.
With those speeds my Asus cards crashed. Had to dial down the hashrate to 177.5 for them to be stable. So now going to use some commands in claymore to run the Asus cards at lower speeds while letting my other cards mine harder.
I wrote this to let people know that mining isn't all Bugatti's and caviar. These machines are fickle little cunts that do what they want. No system is the same. So when you post on a forum, people will give you advice on what may work. But what works for them, may not work on your rig. In the end it's up to you to figure it out.
I have spent countless hours after work and on weekends working on this bitch. Hell I've probably spent a few hours just staring at it and thinking about all of the ways I could destroy it slowly.
While I love Etheruem and do value the knowledge gained, I would have made more money just buying Eth and holding.
The guys you see on youtube building sick rigs with crazy specs have been at it for a while. They have worked through the process and know how to solve all of the problems. You have not and will have to work them out on your own.
My whore of a rig will pay for itself soon. But I would suggest that if you want to start building a new mining rig. Check the difficulty chart and make sure you have tons of free time to fuck with it.
I'd post my wallet address for donations since I just saved you $2,600. But I am afraid hackers will steal my monies :)
Hope you enjoyed my mining life story from the past few months.
Edit - Had an Asus card die on me and replaced it with a 1070ti. Nvidia is so much easier!
My rosewill 1200 watt PSU melted the 8 pin port and cable. Had to drop $300 on Amazons last 1300 EVGA.
But my rig has well surpassed it's cost and is still mining away like a champ. Eth for life!

I've started working on modifying the Vive wireless adapter for better passive cooling.

First and foremost: I voided my warranty, this is not a how to, this is an attempt to see if anyone else is working on a similar solution and to get as much input from as many people as possible. Please chime in if you have any thoughts on the subject. I have the Pro version, which means the adapter is under more strain, it's constantly at the bandwidth limit in most games.

I have no background in engineering nor am I in any way qualified to do this, but I did mine bitcoin back in the day and learned a lot about heat accumulation and dissipation. My proudest achievement was running a 6 GPU rig on my balcony for a year consecutively in Finland with the ambient temperature of -30c to +40c. Almost nothing ever caught fire :) This experience leads me to think that it's a bad idea to draw more power trough the headset, from the same battery for a fan. Also I have long hair and am downright afraid of adding a fan to my head.

I have begun to cut off some, not all of the, "plastic strips" covering the openings in the adapter. I intend to remove about half of them, every other to be exact, removing all seems like it could weaken the "chassis" too much. If that is not sufficient then I'll open the entire thing out and try to figure out if there are spots where small aluminum heat sinks could be added without interfering with the reception. What material would be the least interfering with the reception whilst having the greatest possible thermal conductivity? The answer is probably not metal at all?
Here's where I began, I intend to go back and smooth the edges, possibly with a soldering iron: https://imgur.com/a/smMdT7n

I'll try to post updates in comments as the chopping progresses, hopefylly we see some input before entirely "gut the sucker" :)

Anyone considering adding a fan might want to cut off the "plastic strips" covering the openings in the adapter from beneath the spot you intend to add the fan to, especially if you intend to glue the fan on to the adapter. Actually I can guarantee this will improve the (unknown to me) efficiency of your fan mod by a double digit %.

[edit1]
I have removed roughly half of the strips and done some testing, not enough to say anything conclusive, but the adapter seems slightly cooler after and during intense use. I did play a full battery's worth of Skyrim without seeing a grey screen, this has happened before, but not that often. I discovered the back "plastic strip" has a clip that's holding the enclosure together. Had I known this I would of not cut it, looks like it missing wont be a problem tough. I have clearly created openings that will gather dust, so from here on I'll make a routine of blasting the adapter with air duster from time to time. It's obviously also more vulnerable to liquids now, but I don't see any sweat getting in from the top and sides where the modifications are.

Has anyone opened the adapter up, does a teardown guide exist?

[edit2]
It just occurred to me that anyone using a fan mod would achieve greater efficiency by running a split usb cable, so the fan does not draw power trough the headset. If my current tinkering proves inefficient I will probably go this way myself. Having the fan pull air trough the top of the headset, rather than pushing it in.

[edit3]
10 hours of gaming in and I haven't seen a grey/blue screen yet. Apart from one IRQ error, those usually bsod my whole computer. Unfortunately I seem to be stuck on that front because my mobo's bios dosen't seem to include any IRQ settings at all.

[edit4]
Haven't seen a grey screen since the modifications, but my holodeck is in a room that gets no heating, so the ambient temperature has been 5-10c less than usual. So I'm pretty sure I have no valid findings to report atm. I will, only, continue working on the adapter as the problems re-emerge. Doing anything now seems like fumbling in the dark.
[edit5] Been slightly warmer so yesterday when I fired up Moss and turned the graphics options all the way up I experienced the first grayscreen that lasted longer than a second and did not recover on it's own after beginning modifying the adapter. This was after ~20 minutes of playing. So I proceeded on with the chopping, I promise pictures soon but atm there is no light, I have now cut all the strips on all the sides, 6 out of the 18 strips on the top mid part remain and 1/3 on the horn's remain. Please note that I've concluded that cutting the strips on the horns does absolutely nothing heat wise, so knowing what I know now I'd leave them be.

I'm about to attempt to overheat the thing with Moss next and if I succeed, I'll start looking at usb fans.

[edit5]
Did not overheat this time around, regardless I'm looking at fans. Optimal sizes seem like 5cm or 7.5cm diameter. As explained earlier I'll go for a "split cable" or "passthrough" to avoid running any extra current trough the adapter. I'm pretty sure no ones reading this, but I'll keep updating it and will re-publish if I feel like I've gotten the issue sorted. Not covering the button seems harder than anticipated, I should move it... but I don't feel comfortable doing that. I guess I'll order a bunch of fans and see what works out once I have them in hand.
Note to self: the added usb cable/'s should run under, not over the adapter. So that we don't introduce copper wires to block or hinder the signal. This means the minimum cable length is ~13cm. Arctic cooling can move 15.1 CFM / 25.7 m³/h @ 0.08 Sone (@ 1,200 RPM) with a 8cm fan. Settling for less than half of this would be madness. USB to 2 x 3/4-Pin PWM 5V USB Sleeved Dual Fan Power Adapter Cable exists, were not settling for less :) I orderedhttps://www.amazon.com/gp/product/B077PXJRTT/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 mainly because they did not attempt to screw me over with shipping costing more than the 800% markup product.
and https://www.arctic.ac/eu_en/f8-silent.html because they make the best products in the field. at 5v this runs at 400 rpm, completely silent and still shifting 5 CFM or 8.5 m³/h. If this proves inefficient I can try running it with a separate 9V battery, no speed is indicated for 9V, but that'd reach 700-800 RPM and increase the airflow at the same rate.
Still looking for usb male to male type a splitter (all male) these don't seem to exist : /
[edit6]
Gave a try using a soldering iron to smooth the openings and cut edges, not a huge success, but gets the job done.

Did some log digging, things are bad:
The latest log is three days old, it shows the adapter consistently hitting 80c and during one session, I suspect it's Moss, but can't be sure, it gets really bad:

87c that's not a safe amount of heat to attach to the top of your head. That's also a temperature that would kill a GPU if constantly reached.
And here's a snippet for the inevitable nay-sayer claiming I've made it worse it's from a day before the original post and before I made any modifications to the adapter:

Fan arrived, I got the size right, but can't proceed to test before the cable arrives. I did think of a lazy but promising way of testing ways to mount the fan: I'mma just ziptie it to the horns and experiment at different angles with wedges of cardboard to hold it. The fan weighs 71g and the plastic strips that I've removed total about 6g. I'm pretty sure I can shave off up to 10g from the fans plastic components once I decide on a mounting style/method. There'd probably be an another 2g to shave off by shortening the power cable, but in my case I'll need a friend to do it for me and I was thinking of shortening the power adapter cable to the bare minimum too so might as well stack the jobs. I'm also scrounging for a net of some sort to keep my hair out of the fan, that'll obstruct the airflow like a mf especially as I'm adding one to both sides... but I'm hopeful that the fan is overkill enough to still do the job and keep me cooler during Beat Sabre.

ASUS Prime H270-Plus & multiple GPU's

Hi all, In the process of building a mining rig. Before now I've never had more than 4 cards hooked up to a single motherboard. I'm trying to up the number to 8, and I read/found videos of people using 8 cards (with 8x powered "usb cable" risers and 2x m.2 to pciex4 boards) with this motherboard.
So I install windows and the thing boots fine with any 2 of my GPU's (they are various NVIDIA 10 series.. some 1070s and some 1080 Ti's, mixed evga and MSI) plugged in, but as soon as I plug in 3 or more, the BIOS boot screen doesn't show properly and I just get a blinking underscore cursor on an otherwise blank screen. Also, the m.2 pcie adapters don't seem to function at all, no matter which or how many cards are plugged into the board.
My BIOS settings are kosher, I think - made sure to enable the "above 4G remapping", set the m.2 slots to PCIE mode. Not sure if turning on VT-x & VT-d would have any effect, my hunch is no, but I tried it both ways. Most people seem to make their builds with AMD cards, but I have gone with NVIDIA - is there some reason that more than 4 NVIDIA cards would not work on a single motherboard when AMD would?
Anyway, 1 ETH bounty to the person who solves my problem - 2 if it turns out to be anything seriously complicated or require real effort to help me - as I'm losing money on my investment right now. I'm pretty good with both software and hardware, so helping me troubleshoot shouldn't be a total pain.
Or if there are known issues with this board and y'all think I should cut my losses and order a different motherboard, let me know. Hopefully one I can use with the DDR4 & LGA 1151 Celerons I already have - i.e. an ASUS Prime Z270-P? Or am I doomed trying to set up an a build with more than 5 NVIDIA per motherboard?
Please help me /EtherMining!
UPDATE: Based on the feedback I have received, and some more tinkering I have taken the following steps:
CLOSED: Y'all are going to kill me - looks like it was a BIOS version issue. I swear I updated the BIOS when I plugged in the boards, but looks like I was still a version out of date. I updated the BIOS to version "0808" and I've gotten up to 7 cards running successfully. I have a reason to believe the 8th card may be nonfunctional and so I think I have solved my motherboard issue. Also, for the record, all my ports are running in Gen2 not Gen1 and it seems to be working. When I verify that all 8 GPU's are running correctly, I'll fully document my build. Thanks to all who helped, I will be privately messaging the comments that finally spurred me to check the BIOS version and offering an ETH donation. Thanks again /EthMining and have a happy bitcoin-fork-day!

My story behind my mine.

Hello,
I want to show you my mining rig and make a step-by-step tutorial on how to make the rig itself and choosing components, building them into the rig etc. My mining rig design is made out of wood but you can choose any material of your choice if you can work with it. I made my design different then others did so i have alot of space to place my sdd fans etc,. This is a very cheap but very powerful mine, lets get started!
The wooden plate on the bottom is 40 x 60cm and the thickness is 4mm. In the front of the rig the of the beams on the side are 2 x 4.5 x 21.5cm and on top the same kind of wood as on the bottom but now it is 4.5 x 60cm. On the back side there are 5 beams with the height of 12.5cm, the width is 2cm and the length is 4.5cm place them where ever you want but make sure it is stable and place the same wood as the bottom plate in the size of 15 x 0.4 x 60cm
It should all fit and what i want to do is place some pieces of foam on the bottom, the back and the front. The foam will absorb vibration and it makes the mine look nicer. (I ordered them in black, you can order any corlour you like!)(gewijzigd) Now that the rig is done you can start looking for hardware. I had a motherboard lying around of a pc i used in the past, now that i did not use it anymore i could use it for the mine, great way to save some money!
The motherboard i have is DH55HC (I don't recommend buying this motherboard. Use one you have lying around and is capable of mining) Motherboard that i recommend to buy:

(You can buy more then 4gb but i use 4gb and it works fine for me.)
As harddrive you can choose between three options, a USB Drive, SSD or a HDD. I don't recommend going with a HDD because they take more power then a SSD or a USB Drive and they break earlier, etc. I went with a SSD because i wanted it to boot as fast as possible and i could not be slowed down by the hard drive. A USB Drive is also a great option because they are cheap and plug in without any external power. You can take any hard drive you want but you need atleast 32gb or more so you have enough space for everything you need. (I got a 120gb Samsung SSD)
I recommend this SSD, it is fast, durable and cheaper then Samsung SSD's:

Now the important step: Choosing a graphics card. I had a realy hard time finding a nice graphics card for the right price, the prices for graphics cards are rising and i was on a budget. Finaly i came out to the Sapphire Nitro+ RX570 4gb Nitro+ for the price of around ~320$ I only bought one card because as i said i was on a budget and i have my gaming graphics card which is a MSI 1060 6gb that i plug in the pc when i go sleep and when i get home from school i plug it into my game pc again. Because the RX570 is changing prices really fast now, here is the link to search suggestions on ebay for the RX570:
https://rover.ebay.com/rove1/711-53200-19255-0/1?icep_id=114&ipn=icep&toolid=20004&campid=5338243794&mpre=https%3A%2F%2Fwww.ebay.com%2Fsch%2Fi.html%3F_from%3DR40%26_sacat%3D0%26LH_BIN%3D1%26LH_ItemCondition%3D3%26_nkw%3Dsapphire%2Brx%2B570%2Bnitro%26_sop%3D15
And this is my MSI 1060:
https://rover.ebay.com/rove1/711-53200-19255-0/1?icep_id=114&ipn=icep&toolid=20004&campid=5338243794&mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2FMSI-GeForce-GTX-1060-Gaming-X-6GB-DDR5%2F232045691151%3Fepid%3D19003305110%26hash%3Ditem360700410f%3Ag%3AG2AAAOSw1aVZ18ag
Even though the price of the RX570 went up alot i still think this is the best card to buy for mining.(gewijzigd) eBay MSI GeForce GTX 1060 Gaming X 6GB DDR5 MSI GeForce GTX 1060 GAMING X 6G Twin frozr VI thermal design raises the bar of graphics card Air cooling. Torx fan 2.0 is the enhanced version of the Patented torx fan technology which generates 22% more Air pressure for better cooling performance while further reducing noise levels. | eBay!
Next up is software, i run the PC on Windows 10 with the mining software Claymore's Miner. I mine Ethereum with the pool ethermine.org, I think that is the best pool to mine on because it has low fees +-1% and Claymore's miner mines takes around 1-2%. I know there are better miners out there but i will stick to Claymore's because i like their miner and i support them. Of course you can choose to mine a different coin with a different pool and using a different miner! It is all up to you! With my Ethereum miner i mine with a total of 29MH all day and in the night i have another 24MH added.
I also overclocked both of the cards. My RX570 has Elpida memory (You can find what memory type you have using GPU-Z) If you have the same memory you can use the attached bios flash, to flash a card you need atiflash. I hope you liked this thread and i hope i helped some of you out, have fun mining! If some of you want to donate any ETH, BTC or LTC you can send that to these wallet codes:(gewijzigd) rx570_1150-2100_rev2.rom 256.00 KB ETH: 0x7F660f909dd5FbC045e82A34F6575cf3B595d7E6 LTC: LRom47cow8wsc2Py3WSMw7DXezXXvXojLg BTC: 1BV1QqS9k8Yyq9oVUKozQE6h1ebzngMdDL

[US-WA][H] 11-GPUs, My 2-in-1 Mobile Mining Rig [W] BTC/BCC/USD/PayPal

I have this posted on Craigslist at the moment, though I would be willing to ship as long as you're willing to piece it all back together once it all arrives, and pay for shipping lol.
I'll add the link so anybody can see photos, but I'll just copy/paste the entire listing below as well.
https://seattle.craigslist.org/see/sys/d/selling-11-gpu-mining-rig/6370381005.html
I'm selling my pride and joy of the last 4-6 months of my life, sadly I can't keep it in my apartment another day and have to hear my girlfriend nag about how much time I'm spending mining any longer.
This is really two separate rigs that I have combined into a single entity (see pictures for details).

RIG #1

Motherboard: Gigabyte GA-X99-Phoenix SLI CPU: 6th Gen. Intel Core i7-6800K (6-Core/12-Thread) (15M L3 Cache | 3.60 GHz) RAM: Corsair Vengeance 8GB DDR4 2400 MHz (x2 for a total of 16GB) Heatsink: Cooler Master Hyper 212 EVO (w/2 Fans) PSU: Corsair HX1000 1000W 80 Plus Platinum Grade Fully Modular GPU #1: MSI GTX 1060 Armor 6gb GDDR5 GPU #2: MSI GTX 1060 Armor 6gb GDDR5 GPU #3: MSI GTX 1060 Gaming X 6gb GDDR5 GPU #4: MSI GTX 1060 Gaming X 6gb GDDR5 GPU #5: EVGA GTX 1060 6gb FTW (Tri-Fan) Risers: Explomos Multi-Powered USB 3.0 (VER 008S) <----Newest Model

HDD: 2.5" Laptop SATA 7200rpm 1.0 TB HDD w/Windows 10 Pro

RIG #2

Motherboard: Asrock H110 Pro BTC+ (x13 PCIe Slots) CPU: 7th Gen. Intel Celeron Dual Core @ 2.60 GHz RAM: Corsair Vengeance 8GB DDR4 2400 MHz (x1 for a total of 8GB) PSU: Corsair HX1000 1000W 80 Plus Platinum Grade Fully Modular GPU #1: MSI GTX 1060 OCV1 Mining Optimized 6GB GDDR5 GPU #2: MSI GTX 1060 OCV1 Mining Optimized 6GB GDDR5 GPU #3: MSI GTX 1060 OCV1 Mining Optimized 6GB GDDR5 GPU #4: EVGA GTX 1060 SC Gaming 6GB GDDR5 GPU #5: XFX RX 480 8GB RS Hard Swap Edition (Custom BIOS Mod for 29-31 MH/s + Undervolted for Lower Power Draw) GPU #6: Red Devil RX 480 8GB (Tri-Fan) (Custom BIOS Mod for 29-31 MH/s + Undervolted for Lower Power Draw) Risers: Explomos Multi-Powered USB 3.0 (VER 008S) <----Newest Model

HDD: Western Digital 7200rpm 500gb 2.5" Laptop SATA HDD w/Windows 10 Pro

The features that set this rig apart from most others is the fact that it is 100% portable and easy to move. Its compact design makes for an easy-to-manage mining experience, doubly so with the fact that the entire rig is on wheels! From RIG #1 to RIG #2 I have connected an Ethernet cable; doing this I am able to create a Bridged Network Adapter and effectively enable a constant internet connection to RIG #2 from RIG #1 without ever having to do anything more than simply power each device on. Of course, you'll have to have some way to give internet access to RIG #1 for this to work properly, though this should come as no problem considering RIG #1 has built-in Wi-Fi access, as well as a second Ethernet port on the motherboard.
If you're wondering how much effort you'll have to put in from the time you buy it and get home, I'll say that this rig takes absolutely ZERO effort to install. The entire rig is ran headless, with Teamviewer installed onto both rigs, so you don't have to have anything plug into it except for the x2 power cords from each PSU, and an Ethernet cord from your router into RIG #1. That's literally it. 3 plugs, then connect to each rig with Teamviewer from a separate device (there's an app for that).
This rig can literally mine anything you want, I have a multitude of mining software already available on the device, and custom made batch files in each folder so literally all it takes is for you to decide which coin you want to mine, then double click a single file and start raking in the coins!
Here are a few hashrates that you can expect to get if you choose to utilize all 11 GPUs to a single coin:
ETHEREUM (Ethash Algorithm) - 240 MH/s ZCASH (Equihash Algorithm) - 3300 sol/s NICEHASH (Auto Profit Switcher Software) - $20+/day in Bitcoin (which is over $7000 if you didn't know!)
I'd be happy to help you get everything squared away, and would honestly just like to see this thing go to somebody that will appreciate its glory. I spent a LOT of time building this rig, and I'm sad to have to see it go, but my girlfriend is constantly bitching about it and I'm beginning to procrastinate homework these days because of it, so sadly it is time to see it go...
I have about 90% of the original boxes that the hardware came in when I purchased it, and I've only had it up and running for about a month total, so there is massive life left to be enjoyed with this guy. With the way the crypto is going (or at least Bitcoin), it is a wise investment to get into it now while you still can ;)
SERIOUS BUYERS ONLY!!!!!
You may contact me either by email via this Craigslist listing, or by phone @ show contact info .
I will accept cash, PayPal (in-person ONLY), or Bitcoin/Ethereum and other Cryptocurrencies as form of payment.

Up to $120 bounties for answering altcoin mining questions

I'm thinking about sinking some major money into mining. Probably $15,000 to $20,000. Not all up front but sliding into it pretty quickly.
I've got about three rigs up and running with ethereum but I have several issues I want input on. I am setting aside a $40 bounty for the three top answers ($20 for the top, two $10 for the runner ups) paid in bitcoins. I will be posting this in several places.
If there is a REALLY good answer I will offer an additional $80 (total of $100) for the top answer. This is my research that may save me from making a big mistake.
I live in the Midwest with temperature that hits 100f / 38c for 3 to 4 consecutive months a year. I want to run this operation in my garage.
Cooling. This is by far my biggest concern. I live in the Midwest with three months of 100f / 38c per year. I've dealt with this before with litecoin. I don't want to have to air condition. In my previous experience fans aren't adequate.
Will this gpu be able to stay cool at the temps I've mentioned without air conditioning?
http://www.newegg.com/Product/Product.aspx?Item=N82E16814131676
If not … does anyone have experience using dialetric fluid / oil to submersible the cards in? I'm going to have to cool the oil somehow right? Is there a book way to do this? (Drop sealed containers of ice in the vat, pump it thru an oil radiator?
Hardware. As linked above I'm leaning towards the 390X to try to retain value a year from now. I'm thinking of using this motherboard
http://www.amazon.com/ASRock-Motherboard-H81-PRO-BTC/dp/B00HEUIS2G
USB risers. http://www.ebay.com/itm/Powered-PCI-E-Express-1X-To-16X-Extender-Riser-Card-With-60CM-USB-3-0-Cable-/301105921855?hash=item461b4fbf3f:g:oGMAAMXQuTNTMSBV
Mining. Has anyone developed a proprietary ether miner they are selling? Has vertcoin or monero mining stayed profitable with a .09 kw electric rate between the litecoin dropout and today if you are able to get a good cooling (non ac) system in place?
Power. I'm leaning towards this as my PSU. http://holybitcoin.com/product/dps-2000bb-breakout-adapter-board/ (I know I'll have to install a fan for the PSU). I'm fairly comfortable with the electric side of things until it gets to the PSU (I understand amps, volts, watts, and required wire gauges. Any warnings on running server PSUs?

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.

Building a Dual Rig (gaming and mining)

What is your intended use for this build? The more details the better.
I’d like to build a gaming/mining rig. I would like to run 6 graphics cards at one point, might not buy them all outright. So the goal. A gaming computer running the 1070 separately so I can still game and do stuff while the other 5 cards are mining. When im not using the computer, I have the option to put the 1070 to work as well. Is it a stupid idea to combine the two purposes into one super computer? Also, I’m having trouble finding a compatible motherboard and would love suggestions. Finally, I have tried reading on the riser connection info and I’m still not sure. Hopefully those are the correct risers?
If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)
Nothing too crazy. I have done the research on that side of things and the things selected should make me happy.
What is your budget (ballpark is okay)?
$2000-3000 (depending on how many gpu’s I buy at onece)
In what country are you purchasing your parts?
U.S.A (amazon, here is the link my current list. https://www.amazon.com/gp/registry/wishlist/2NAC9YOHISTRI/ref=nav_wishlist_lists_4)
Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).

I took the plunge - 2x 7970's on their way for potential rig - I have no idea what I'm doing - Help appreciated!

So since this past Spring break, my brother in his all powerful insider knowledge on this strange thing named BitCoins introduced me to this bandwagon. I've since joined in and bought all I could muster with the funds in my bank without ruining myself and have thus far reaped a beautiful profit that my wife deems pleasant. This is, of course, something EXTRAORDINARY. Ahem. So I decided to wager my trust I've earned with her with said investment, and have decided to use a few more funds to build a mini miner. Obviously this won't be the mega tank that you see all over Youtube, Just a simple machine that may have the potential of 1.6GH/s is my hope.
So this is what I've bought so far:
Total thus far after Rebates & Selling Games: ~$1300 USD
Estimated 1.6GH/s with profits beginning in ~85 days (Before crash, of course XD - Now who knows!)
Great thing is if all this goes kaput, I'll at least be able to resell it all! :D
I have a monitor around for initial setup, and all the other obvious peripherals. What I am in need of are some tips or links in setting these 2 guys up. I'm somewhat new to Building a PCI-E Rig, but I'm sure its just as simple as plugging it all in, which I've done countless times before. I know that if I'm on Linux I won't need any dummy plugs for the DVI outputs on the other cards for it to be recognized by the OS. Can it be run purely all on a USB drive? That's one thing I'm a little unsure of.
Mostly my questions consist of:
I don't care much for people bantering about how difficult it is now to mine, or how ineffective this might be, I've read my share about that. I plan on just having this run in the corner of my little apartment for a few months while I go to school/work/walk the dog/etc... I would like tips or any insider info on other fellow 7970'ers on how to maximize my performance with these two cards at my disposal. And of course those who do help me in my time of need and once it's all beautiful and vampiric-sparkly like will get Brownie Points in the afterlife.
Last computer I built was back in 2004 so that I could play Half Life 2. And I was on a budget back then too. So I'm not too savvy with all this new cooling hardware and techniques as I've never had to deal with things that exceeded 4x AGP.
I'll post pictures and videos of all the fun I have with this adventure :D
Update
Thus far I have only received my two 7970's and boy do they look beastly. I've never held a card that manly before.
2nd Update
Everything came in! Goodness it's difficult to do a headless Linux Box! for sake of time, I think I'm just going to buy a cheap sata harddrive.
3rd Update
So here's the final photo of it running with 2xx7970's
I'm still waiting for the riser cables to come in to mount the other 3 cards.
I haven't uploaded the videos of me building it all just yet (btw I sucked at putting it all together XD)

Try this with a potatobox...one gaming PC, three rooms.

I'm sure I'm not the only person who games in more than one room, but there's no way I could afford a high end rig at every spot. So I figured why not put all my cash into one mega rig and have it serve double duty....scratch that, triple duty! I'm also into AV/Home theater and hate input lag, so steam streaming isn't gonna cut it.
http://i.imgur.com/bhZQT6z.jpg
The PC lives in the office...this is where the mouse/kb gaming happens. PC speakers aren't going to cut it, so I've got a receiver feeding two pioneer bookshelves and a sub under the desk. From here, I run a 75ft HDMI cable, ethernet cable, and USB cable down to the basement.
http://i.imgur.com/m6BmG7c.jpg
In the basement I've got a full dedicated theater...96" screen, 1080p projector, 5.1 paradigm studio speakers powered by an anthem mrx300, and a completely ridiculous 2000W 18" velodyne sub right behind the leather couch. No need to worry about a loud PC making a lot of noise, because it's on the other side of the house! The USB cable feeds into a hub, where I attach all the wireless receivers for controllers, bluetooth, etc. I usually use a dual shock 4 for gaming down here. Before I feed the HDMI into the receiver, I use a splitter to send another 30ft HDMI upstairs. The ethernet plugs into a switch to feed all the consoles and other gear, and I run another cat6 up to the living room as well...everything is hardwired.
http://i.imgur.com/Ta3T0ZJ.jpg
Up in the living room I've got a 60" panasonic ST30 plasma and a pioneer soundbar for some "casual" gaming. I ended up not needing to run another USB hub for the controller because the dual shock 4 runs perfectly fine wirelessly through the floor. The best part? It barely works with the PS4 sitting in the same rack as the BT adapter...ain't that a B.
You'd think all of this would be a PITA to manage, but all you literally have to do is turn the receiver or the TV to the PC's HDMI input, and it automatically switches everything. Otherwise, it's outputting to the monitospeakers in the office by default.
There's absolutely no way you could do this with a console - for one, you'd never be able to extend the range of the controller. God forbid you needed to put in a disc, you'd need to run around the house. And although you can probably make it work with enough HDMI splitters, the dual video output makes things super easy. Why spend $1200 on three PS4s when you can spend it on a few GTX 780's that you can actually use wherever you are? It's not nearly as hard as it sounds, and it saves a TON of money to consolidate everything into one system instead of spreading your gear thin across a few. Even if you don't want to get as crazy as me with the wiring, steam home streaming does work pretty well on super cheap PCs.
And to top it all off, when the PC is idle, it mines bitcoin...because why not?
Console cheaper than PC....pfft.

How much power do I need for this?

I keep seeing all these rigs and I really want to make my own as it looks like a lot of fun.
I'm planning to get 3x GIGABYTE GV-R927OC-2GD and these USB risers.
I've got an i5-750, an old ASUS P7P55D-E LX, and 8gb RAM leftover from an old system.
Any help is appreciated!
Edit: Going with the Corsair AX860! Thanks EvilToasterOven!
