This project is intended to be fun and not any sort of insurance/promise/guarantee. If you’re looking to start somewhere smaller, please keep your eyes out for my other guides as I intend to do a few and will update the site accordingly. As the title indicates, we’re going to be building an Ethereum mining rig, specifically a 6 GPU mining rig. The longest part is planning, build time should only be a couple of hours depending on your planning and experience.

I suggest keeping your coins safe stored using the Ledger Nano S Cryptocurrency Hardware Wallet, it’s a hardware wallet that supports all major crypto currencies!

The following is a list of build components needed for our project:

Custom Mining Case – There are a couple different options here, consider the space you have available, cooling, and build fit when making your decision. I personally prefer rack mount but that’s what best fits my need and preference, open air is good too especially in keeping your rig cool. The following are a few ideas for your convenience.

Motherboard and Processor (CPU) Budget conscious – Here’s a combo for mining ETH, uses up to 6 GPU’s, compatible with everything in this guide including faster processors, and won’t break the bank (all cpu’s and motherboards listed in this guide are interchangeable):

MSI Pro Series Intel Z270 SLI PLUS & Intel Pentium G4600 Processor 7th Gen

Motherboard – The following are a few more motherboards compatible with the Intel G4600 processor, all of which are also compatible with the additional processors listed below this section:

Processor – If for whatever reason you’re looking for a beefier cpu, I’ve listed the following Intel processors which are compatible with everything else in this build guide.

Power Supply (PSU) – Your going to need a 1000w Platinum Rated PSU, power efficiency is essential for maximum gains when mining. Platinum or gold rather than silver or bronze, this being the industry standard rating efficiency of a computers PSU.

Graphics Cards (GPU) – Remember, you’re going to need a total of 6 for this build. You’ll need to pay close attention to power consumption and cooling capability.  Nvidia has the GTX 1070 which produces a 30Mh/s hash rate while consuming only 100 watts of power and the 1080 with slightly better specs. Another choice would be AMD, either the RX 580 or RX 570. The Rx 580 does roughly 29Mh/s and the Rx 570 does roughly 27Mh/s, no guarantees. All mining rig build requirements are the same for either the 1070 or the Rx 580/570, or any other hardware variances of items listed. Keep in mind the GTX 1070 power usage (100w vs 135w per GPU) when mining. They’re listed below along with an alternative but you’re not limited to these choices:

RAM 8 GB – You really don’t need a lot of system memory and 8 GB might be a little overkill but the price difference between 4 and 8 is so miniscule that I figured, might as well. The following are some compatible 8 GB DDR4 desktop ram sticks.

USB Riser Cables – You need riser cables to connect all the GPU’s to the motherboard whilst allowing adequate spacing between each for sufficient heat disbursement making them a necessity in a build this size. I’ve listed a couple of choices below, not much difference but some people like choices:

Hard Drive (SSD)  – You’ll need a hard drive large enough for your OS and for your mining software. You don’t want it to be full as to not slow performance, aim for twice the needed space. The following are a few possible suggestions:

Operating System (OS) – Windows 10 Pro seems to have the most user friendly driver support so it’ll be the OS I recommend and use in this build reference:

Peripherals – Your going to need to hook up a monitor, mouse, and keyboard for initial setup and configuration. If you don’t have them available, I’ve listed some below:

Hardware Assembly and Software Configuration

  1. Un-box hardware.
  2. Assemble Mining Case.
  3. Install processor and RAM onto motherboard, be sure to use thermal paste as/if required, more than likely it is.
  4. Plug in risers.
  5. Mount motherboard in case connecting motherboard PSU (leaving unplugged from power source).
  6. Mount and connect HDD.
  7. 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.
  8. Plug in PSU connections.
  9. Connect peripherals (mouse, monitor, keyboard) and internet.
  10. Verify ALL connections.
  11. Power on to install the OS and mining software.
    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. A quick search on Google will reveal your specific motherboard BIOS update if using a different motherboard.
    2. Configure Motherboard BIOS with the following settings changes:
      1. Settings > Advanced > PCI subsystem Setting: PEG 0 and PEG 1 set to Gen1
      2. Above 4G Decoding (cryptocurrency mining) should be set to Enabled
      3. OS settings: disable Windows 7, enable Windows 10
      4. Save and reboot
    3. OS / DRIVERS / MINING Setup:
      1. Either having built your own on Microsoft website or bought it pre-loaded, boot from Microsoft Windows 10 Pro | USB Flash Drive.
      2. Clean install Windows 10 Pro x64 (64-bit).
      3. Download and install Nvidia Drivers, or your specific GPU drivers if different.
      4. Install MSI Afterburner, overclocking software. Set memory clock to 600 and power to 70. This will give you approximately 30Mh/s per 1070 GPU.
      5. Ensure all system drivers are installed by accessing device manager.
      6. Rename PC, go to Settings > System > About and select the Rename PC button in the right column under PC.
      7. Install Claymore Dual Miner editing the config file inputting your Ethereum address and miner name. You can put a shortcut of the mining software .exe (executable) file in the system startup folder enabling auto-start when Windows boots.
      8. Disable windows update.
      9. Set power profile to ‘always on’.
      10. Enable remote access eliminating dedicated peripherals.
  12. Start the mining software.
  13. Make sure fans are fully functional.
  14. Adjust settings to achieve maximum hash.
  15. Sit back and collect your profit!
