It’s finally time for an update to my popular 2013 Litecoin mining guide! It’s fastest bitcoin mining rig how to years later, and Ethereum mining is where it’s at for GPU miners, so that’s what I’ve focused on. I’ve kept the same format and detail level as my old guide, so if you were around back then, you’ll know what to expect.
This guide will be broken into several parts, each focusing on a different aspect of building your first mining rig. First, let’s take a look at what you’ll need in terms of hardware to put a respectable Ethereum miner together. Build your own Ethereum Mining Rig, part 1: Hardware Here is the list of hardware that I recommend. Don’t worry if you’re not able to get exactly what’s on this list, I provide some excellent alternatives below the table. Motherboard Generally, any motherboard with PCIe slots on it is suitable for mining—typically one GPU per PCIe slot. The PCIe slots don’t need to be full-length, as we can attach GPUs to 1x slots with the help of risers.
GPUs onto one motherboard, even if that board has enough PCIe slots to physically accommodate them. My top choice is currently the Asus B250 Mining Expert board. GPUs and 3 power supplies right out of the box. However, it currently costs about the same as Asus’s mining board, and for the money I’d rather stick with Asus. Finally, the Biostar TB250-BTC is also aimed at miners, and costs considerably less than the Asus and ASRock offerings.
6 GPUs, but that’s likely all that the majority of us need. If you only want to use 3-4 GPUs in your rig, then you’ll have a much easier time. Most boards with up to four PCIe slots should accommodate a GPU in each. Keep in mind that you can use old hardware that you have sitting around—the board doesn’t have to be recent.
Processor This one is easy: buy the cheapest CPU that works with whatever motherboard you pick. When it comes to mining, the GPUs do all the work. Your CPU will essentially sit idle, so there is no reason to waste money on anything other than the bare minimum. All of the motherboards that I recommended based on Intel’s LGA 1151 socket, so that means the Celeron G3900 is probably the best choice.
