We got a great response from the 6 GPU Mining Rig build series we did and decided we’ll do another. This time, we’re gunning for a 19 GPU Ethereum Mining Rig, pushing AMD’s B250 Mining Expert motherboard to it’s limit. We’re calling it an Ethereum mining rig because we’re bullish on Ethereum. But, of course, the rig will be able to mine the usual suspects that regularly top the profitability sheet including:

  • Ethereum (ETH)
  • Ethereum Classic (ETC)
  • Feathercoin (FTC)
  • MONAcoin (MONA)
  • Zcash (ZEC)
  • Zencash (ZEN)

As usual, we mine what is most profitable and convert it into what we want. As things stand today, however, it’s more profitable to just straight-up mine Ethereum as opposed to converting something else. Like most things, that too, will change in time.

Mining-capable GPUs are hard to come by once again. While price-wise GTX 1070 cards are usually the better buy (they pay off faster and mine at a very similar rate) we tripped across some EVGA GTX 1070 Ti cards that were priced right.

Missing Mining Rig Parts

What’s missing? We are only specifying 13 1070 Tis. Why? Everything we’ve read says that you can only get 13 to run and then you round out the board with 6 other cards. We’ll keep you posted when we’ve selected them. We’re also still deciding what we want to do for the PSUs (or should I say, we’re shopping around for good deals on PSUs). We may go with server PSUs with breakout boards or may stay off-the-shelf. And, there are some parts we have kicking around so we didn’t mention anything beyond the core components (Y-splitters, etc.).

We’ll do a complete writeup and include the final build list then. This one isn’t going to be as straightforward. There’s fussiness getting all 19 cards up, and we might try a new OS this round. We’ve been running Windows 10 historically, but certainly aren’t tied to it.

Stay tuned. Almost all of the components have arrived or are en route. It looks like a couple of pieces may hold us up a bit.
