Greetings ladies and gentleman,

I just finished building my Ethereum Mining Rig and boy is my middle finger tired. Seriously, I’ve never built a mining rig before and let me say, its a lot different in my opinion than just building a regular ole gaming computer. The process took me a bit of time but I’ll break down what I’ve done, parts I used and steps to take as well as things you might want to do differently.

My rig as it sits is only running 3 GPU’s with space for 3 more and I’m getting 97.5 MH/s.

#1. Ethereum Mining Rig Hardware

CASE: $119  6 GPU Custom Mining Rig Frame

MOTHERBOARD: $140 MSI Pro Solution Intel Z170A LGA 1151 DDR4 USB 3.1 ATX Motherboard (Z170A SLI Plus)

CPU: $40  Intel Celeron G3900 Dual-core (2 Core) 2.80 GHz Processor – Socket H4 LGA-1151Retail Pack

RAM: $60 Crucial 4GB Single DDR4 2133 MT/s (PC4-17000) CL15 SR x8 Unbuffered DIMM 288-Pin Desktop Memory CT4G4DFS8213

SSD HD: $40  DREVO X1 Series 60GB SSD 2.5-inch Solid State Drive MLC SATA3 Read 500MB/S Write 90MB/S

USB Adapters: $7.99 ea/3 packs  Cable Matters 2-Pack, Right Angle SuperSpeed USB 3.0 Male to Female Adapter

Video Card Risers: $50  MintCell 6-Pack PCIe VER 006 PCI-E 16x to 1x Powered Riser Adapter Card

6 Video Card GPU’s: $550 ea plus NVIDIA Founders Edition GeForce GTX 1070 8GB GDDR5 PCI Express 3.0 Graphics Card (You can get 1080 FE’s for same price but they dont mine ETH as well)

Power Supply 1 (for the 6 GPU’s): $175 (Amazon) CORSAIR HX1000 Series CP-9020139-NA 1000W ATX12V v2.4 / EPS12V 2.92 80 PLUS PLATINUM Certified Full Modular Power Supply

Power Supply 2 (For the board and everything else) $110 (Amazon) CORSAIR TX Series TX850M 850W 80 PLUS Gold Modular Power Supply

*Note: The GTX 1070 FE GPUs need about 150 W each to run properly so trying to run this entire rig off the 1,000 W PSU alone will result in damage to the PSU. Melting cables, connectors or worse. I know, hence the update on 9/24/17.

$665 Total Before GPU’s

Cost as Built: $3,965 with Shipping

The case wasn’t too bad to put together and if you buy from the link above, they also have a how to video on their site that I followed. The only thing about this case it is it couldn’t have cost more than $5 for materials. The holes are cut perfectly and its sturdy, but honestly, next time I will likely spend the $250 and get a nicer case that comes with Fans.

Once I got the case built, I started on the Motherboard and CPU.

I was extremely delicate with my motherboard and CPU and I either STILL managed to bend or break a CPU pin in the bay or it came that way. First thing you will want to do is add your little Foot screws with bolts to the board so it doesn’t make contact with anything underneath. Where the CPU goes, you’ll see a black plastic cover and a metal mouse trap looking latch. Push the lever down and around to clear the casing and slowly move it back. This will release the metal frame that keeps the CPU chip in place and enable you to take out the black cover.  You dont have to unscrew anything but you’ll be tempted!

Next, take your CPU and look at it. You will see two little indentations on the sides and if you look at the CPU bay, you will find the two teeth that should fit into those indentations. Make 100% sure you are putting the chip in where it belongs. GENTLY place the CPU into the bay. It should drop right into place. If it doesn’t, then make sure you’re putting it in properly. Now, you can take the CPU heat sink and fan and line it up to the holes in the motherboard. Once set, push down on the legs from the top and “click”. Go ahead and set the board into the case.

I should note that if you plan on Dual Mining with this rig using Claymore Miner or something, you may want to get a more powerful CPU as the d-mining things like LBRY mine using CPU power instead of GPU power.

Now, unless you read the book that came with the Motherboard, you may not know that the RAM should start in the DIM 2 Slot. Just push down the sides on the board so your RAM fits and push down gently until you hear the clicks of both sides locking into place.

These are pretty simple to install. Just line em up to the bottom of your GPU card and push in until you hear the “click”. Now you can go ahead and connect one end of your USB cable and the power cable.

Now you can go ahead and plug in the power cables to the motherboard. Make sure the cable that says CPU on it goes into the CPU. Everything is labeled and or fits where they belong so this shouldn’t be too difficult. Go ahead and place the Power Supply in the case and make sure it sites flush against the front frame. Here you can take the two metal L shaped fasteners and screw them down to hold the PSU in place in the case. One on the right side, frame on the left and one on the rear.

The cards should set right in the case pretty easily. Look at this picture for an example. Just screw them in at the pre drilled holes.

Pretty easy here too. Just connect your SSD Drive using the SATA cable. Now is a good time to plug your PCIE USB Adapters and USB Male to Female Connectors into the board. Then connect those to each video cards USB cable. Just to stay organized you should plug GPU 1 into Slot 1, GPU 2 into Slot 2, etc.

 

 

At this point you should have everything plugged in, mounted and ready to go. You’re probably thinking, “How do I turn this on?!” you have to either install a button or just use a flathead driver to connect the two pins on the board. You can see which two in your motherboard manual.

Now, some things you need to know from here.

BIOS FLASH

A. Your BIOS will need to be flashed before your GPU memory will be counted. You can follow this video. Sounds scary but it was very easy.

You’ll need BIOS version: 7998v1B

You’ll also need a Bootable Thumb Drive to put the Bios file onto. I used https://rufus.akeo.ie/ to create mine and it was super simple. Then I just pulled the BIOs file into it and I was ready to go.

DOWNLOAD YOUR VIDEO DRIVERS

B. You’re going to want to download the latest Video Card Drives for your card.

Download Claymore Dual Miner

C. You’ll need a copy of the Claymore Dual Miner software.

JOIN A MINING POOL

D. When all is said and done, you’re going to need to join a mining pool! After some digging and reading I found the Dwarf mining pool to be the easiest. When you open the Claymore folder you’ll see a file called Start. Right click and edit that,wipe the line in there now and replace it with ethminer.exe -G -F http://exp-us.dwarfpool.com:81/YOUR_WALLET/YOUR_WORKER

Replace YOUR_WALLET with your ETH Wallet and YOUR_WORKER with whatever you wanna name your computer on the system. This is mostly for people running multiple rigs in the pool so they can identify which rig is producing what.

When you get everything running, you’ll want to do one last thing and that is run Afterburner

Once AB is open you’ll want to use these settings (or experiment if you wanna try and dial things in more) Power Limit + 90%, Core Clock + 210 MHs, Memory Clock + 830 MHs.

At this point you should be getting around 197 MH/s with your 6 GPU’s.

I hope you enjoy this How-To guide and I hope it saves you all of the time I spent digging for all of these little details.

If you’re loaded with ETH already and care to tip for a great write up, I can get my other 3 GPU’s. 🙂

UPDATE 8/12/2017

I got my 6 1070 FE’s installed. Only 5 are currently being recognized so I’m sorting that out.

I also found myself running into a DAG error which I resolved by changing my virtual memory settings. The video below resolved that for me.

Then, I realized I needed to go back and overclock in After burner again since I added GPUs. Now that there are more GPU’s in the rig, things are running hotter and I would get a bunch of GPU failed errors in Claymore. To remedy this I increased my Fan speed to 80% and locked that in.

With the five GPU’s currently I’m running at around 161 MH/s total.

Will update when I’ve resolved the 6th GPU which from what I’m reading is a common issue not explained anywhere.

Update: I have all 6 GPU’s purring away at 197.5 MH/s. The problem with the 6th GPU was that I just needed to download the latest NVIDIA driver and install it. Once complete, the 6th card popped up and joined the rest. Everything has been going very smooth thus far.

I will say that this setup using the Claymore miner really shut down my wifi network causing everything else to lose connection or crawl to the point of not being useful. I couldn’t even watch Netflix. I ended up buying a $150 router and that didn’t help. What ultimately helped was switching to Ethermine.
