2022 Guide to Building a Crypto Mining Rig

Building a 6 GPU Crypto Mining Rig is a fun project and a great source of passive income. This guide will help you find and assemble the best crypto mining hardware currently available, to build your very own DIY crypto mining rig. Assembly time for your crypto mining hardware is about 3 hours and this mining rig is currently generating right around around $500/mo of digital currency (in February 2022). The exact amount varies depending on the current market price of the coin you are mining (Ethereum, Monero, Zcash, etc).

Sidenote: If mining isn’t your thing, and you are just interested in purchasing some cryptocurrency as part of your investment portfolio, I personally use and recommend Voyager. Download the app and trade $100 to get $25 of free Bitcoin. Use code JOSWDN to claim your free BTC.

6 GPU Ethereum Mining Rig Hardware Build List

Listed below are the components along with the amount you will need to assemble your GPU mining rig. Once your components arrive, you will want to come back to this guide for assembly and configuration instructions. I’ve included a YouTube video further with complete assembly instructions as well. If you find the guide helpful, give me a follow on my YouTube channel. I post frequently about crypto mining, trading crypto and other cryptocurrency related topics.

5 Minute 6 GPU Ethereum Mining Rig Assembly Video

1x Power Supply – 1200 Watt Gold Rated Power Supply The key here is to have an efficient power supply that will save you over the long run in electricity costs. Look for Gold or Platinum rated (as opposed to silver or bronze). This is the industry standard for rating the efficiency of a computer’s power supply unit (PSU).

1x Motherboard/CPU Combination – What is the best motherboard for mining Ethereum? I’ve listed below my favorite motherboard and processor combo that is compatible with 6 video cards.

MSI Z390-A PRO LGA1151 | Intel G530 CPU

If the motherboard listed above is out of stock or difficult to find, these motherboards will work equally well for a 6 GPU mining rig.  Just be sure to match the motherboard with the correct processor (under ‘frequently bought together’ in the Amazon listing).

6x Graphics Cards 

First Choice Nvidia GTX 1660–   The very efficient Nvidia GTX 1660 can produce a hash rate of 30Mh/s using only 80 watts of electricity and is the best GPU for mining in 2022. It is much more power efficient than most of the AMD cards available on the market. Get one with twin fan design as they seem to run cooler than some of the other models I’ve tested. I put this card in all the rigs I build currently. 

You can also check eBay or find other recommended mining GPU’s in my mining GPU comparison guide or the GPU Price / Performance Comparison Google Sheet (Updated Daily).

A close second choice for a mining GPU if the previously mentioned GPU is hard to find or out of stock, would be the Nvidia GTX 3060TI, capable of 60MH/s at only 160 watts of power. I’d recommend upgrading to a 1200 watt power supply as you will be doubling the mining capacity of your 6 GPU mining rig.

1x RAM (System Memory) –  16GB RAM – You need a fair amount of system memory to mine Ethereum effectively. 16GB should be enough to also mine other cryptocurrencies like Monero.

6x USB Riser Cables –  USB Riser Cables – These are to connect the 6 graphics cards to the motherboard and allow spacing between cards for heat dissipation and are necessary when building a rig with this many GPU’s. I like the MintCell 6-pack sold on Amazon.

1x Hard Drive (SSD)  –  120GB SSD  for installing the operating system and your mining software. Anything 120GB or larger is plenty of space and will also allow the system to use disk space if needed for swap files.

1x Custom Mining Case –  I’d recommend an Open Air 6 GPU Mining Case. I’ve built several of these 6 GPU rigs for family and friends and any of the popular models available for $80-150 work well.

1x Operating System –   I recommend mining on Windows 10, since it has great driver support for all the best mining graphics cards.

Alternatively, you can download NiceHash OS, HiveOS or RaveOS and flash it to a USB 3.0 thumb drive for a very simple mining set up.

Monitor, Mouse and Keyboard set to configure all the software settings, initially. Once your mining rig is configured and running, you can monitor it and the other dozen you build 😉 with remote monitoring software.

Assembling the Custom Ethereum Mining Hardware

  1. Scroll up to watch the assembly video that shows exactly how to assemble all the hardware components.
  2. Un-package everything
  3. Build / assemble the Open Air 6 GPU Mining Case
  4. Install processor and RAM on motherboard
  5. Plug in all riser cables
  6. Place motherboard in custom open air mining rig case and connect motherboard PSU connector (leaving PSU unplugged from the wall of course)
  7. Plug in SATA hard drive (or optional Linux on USB stick)
  8. Connect all GPUs to riser cables and fasten them to custom case. You might need to experiment for optimal spacing to keep the cards cool.
  9. Plug in all power supply connections.
  10. Connect mouse, monitor and keyboard and an internet connection (I use a USB WiFi adapter)
  11. Check all connections once more
  12. Fire it up and install the operating system and mining software (see additional instructions below).
  13. Make sure fans are fully functional. Start the mining software, tweak settings for maximum hash rates and let it run!

Motherboard, Windows and Mining Software Configuration

  1. Update the motherboard to the latest BIOS using a USB thumb drive. You can find the latest BIOS for the Z170 SLI Plus motherboard here.
  2. Configure Motherboard BIOS with the following settings changes:
    • Settings > Advanced > PCI subsystem Setting: PEG 0 and PEG 1 set to Gen1
    • Above 4G Decoding (cryptocurrency mining) should be set to Enabled
    • OS settings: disable Windows 7, enable Windows 10
    • Save and reboot
  3. OS / DRIVERS / MINING Setup:
    1. Boot from Windows 10 USB install media (you can buy it pre-loaded or build your own on the Microsoft website).
    2. Install Windows 10 Pro x64
    3. Install Nvidia Drivers
    4. Install MSI Afterburner and set memory clock to 600, and power to 70. This will give you 30Mh/s per 1070 GPU
    5. Install any system drivers that didn’t auto-install (check device manager)
    6. Rename PC to mining worker name. Something like Minion001, Minion002, etc.
    7. Install Claymore Dual Miner, edit the config file with your Ethereum address and miner name. Drop a shortcut to the mining software .exe file in your system startup folder if you’d like to auto-start mining when Windows boots up. You can find the system startup folder in Windows 10 by going to: Start > Run  and entering ‘shell:startup’.
    8. Disable windows update using this guide.
    9. Set power profile to ‘always on’
    10. Install your favorite remote access software, especially if you plan to have more than one rig to manage.
    11. Fire up the mining rig and rake in those crypto coins!

I’ve received several questions about configuring drivers, adjusting overclocking/undervolting settings and configuring the mining software. Below, you’ll find a very brief 5 min video showing how to implement these 3 important steps in the mining rig configuration process.

Configure GPU Drivers, Overclocking & Claymore Mining Software

Something I’ve done when building out a GPU mining farm, is to do the OS/DRIVERS/MINING setup and then just clone the solid state drive using a 2 bay hard drive dock with offline clone feature built in.

Congratulations! You are now the proud operator of your very own custom built 6 GPU ethereum mining rig. Be sure to also check out our reviews of the best Litecoin mining hardware and Bitcoin mining hardware.

    Hi,
    Thank you for sharing your knowledge.
    May I know if mining consumes a lot of internet bandwidth ?
    And if my isp will know.
    And may I know which coin you think would be the best to mine ?

    Thank you

    Josh,

    Your link to Amazon for the

    1x Custom Mining Case – I’d recommend an Open Air 6 GPU Mining Case. I’ve built several of these 6 GPU rigs for family and friends using this particular mining case works quite well for airflow and ease of building.

    No longer works. Can you give me specifics on which one you use?

    Why only a celeron processor? I know the gpus are doing the work, but an upgraded processor wouldnt provide any added benefit?

      No additional performance is added by an upgraded processor. The GPU’s do all the heavy lifting. You can dual mine another coin with the processor, but I’ve discovered this affects overall stability and isn’t worth the effort IMHO.

    Superb guide, thanks. Given the price of 1070 GPU cards would 6 1060 6gb cards give a much quicker payback and starting point for a rig ?

      You can mine other cryptocurrencies like Monero, Zcash, etc. Ethereum is just the most popular and usually the most profitable crypto to mine. I use nanopool.

    Hey Josh,

    Very interested in this and going to get started. Thank you for such an amazing comprehensive review also!

    One question: The Claymore file I downloaded from that website – my Symantec software detected a Trojan virus and quarantined it immediately. Do you know of a safer source?

    Hey Josh, great tutorial. Probably the easiest I’ve seen across the few I’ve read so far.

    A quick question: So you’re saying that setting the MC to 600 Mhz gives you a hashrate of 30mh/s? I have a R9 390 8 GB (I’ve been testing it out for Ether mining before I invest in building a multi gpu system), and my MC/CC is set to 1500/1000 mhz and gives me around 30 mh/s. When I overclock it to 1675/1185, it gives me around 34 Mh/s… (Claymore, Win 7 64 bit OS).. temp stays between 60-70 degrees C.

    How are you getting 30 mh/s off 600 mhz on a single gpu? Do you think it is because you’re using a newer gpu?

    Reply ↓
    1. Josh Post author

      Yes, the newer GPU’s are far more efficient at mining. When I first started in 2013, the R9 390 was the latest GPU and I was running the 7950 myself. The power use on newer GPU’s is also much lower.

    Very good guide and an interesting read. I was wondering, lets say you can only lay hands on 3 gpu’s initially. Is it worth bringing up the rig with half gpu’s and then adding the rest as you can find them?

    Reply ↓
    1. Josh Post author

      Certainly! You can buy the supporting hardware and an initial 3 GPU’s and add the rest later when they get in stock.

    Hello!

    You suggested the usage of the GIGABYTE 1070 with the model number #GV-N1070WF2OC-8GD, however, on Amazon (at least on the German Amazon), the power usage of it is noted as 500w and I don’t really understand how six of those are supposed to work together with a PSU with 1000w. Is that information simply wrong or am I missing something?

    Reply ↓
    1. Josh Post author

      That is the maximum that GPU is capable of drawing, but during the mining process this GPU should only use 100-125w. Hope this helps.

    Hello

    I stumble on to this article through google searching for help in building a mining rig.
    And very nice article and is helping me a lot.

    Have a question in regards to the CPU, since some coins can be mined via CPU, what would be the consequences to have a good CPU and also mine something with it while the GPU´s also do some mining, then i would get some extra mining power? or am i thinking wrong here?

    Thanks
