Ethereum mining @ 1GH/s: 40 x GPUs = $5000+ per month

One Week Later...




After enjoying what I had already completed with the 600MH/s milestone, I needed more power efficiency. At this time, all of the systems were sprawled out across the house. From where I started in my main living area (which is used as a large office), I shifted into:


  • Entire living area
  • Main dining area
  • Laundry
  • Spare room 1
  • Spare room 2


On top of all of this, there was mess EVERYWHERE. Networking and power cables down the hallways, grabbing every single PCIe power connector for every single PSU as they were all tapped out, and balancing the power between blackouts and killing 6/8 connector power boards.





I went out and spent just over $10,000 on a bunch of motherboards, CPUs, SSDs, PSUs, and 22 graphics cards. I've just ordered another $3500 worth of gear half way through writing this (and it's only day 14) - with three more CPU/motherboard combos, and six EVGA GeForce GTX 1060 6GB graphics cards. Oh, and I have 20 x new PCIe x1 to x16 risers on the way.





I'm using the resourceful ASUS PRIME H270-PLUS motherboard, as it has six PCIe slots - and with six risers, you can get a heap of power efficient graphics cards into a single system. I've got two of these set up with six GTX 1060s, each sipping around 500W of power total. I chose the Core i3-6100 as I couldn't get my hand on the Celeron G3930 processor at the time, but with the order of three new CPU/motherboard combos, I managed to scoop up the Celeron processor which saves $80+ per CPU ($240 savings total or so).




Here we have the two motherboards that helped me get past 700MH/s... and below, some of the new GTX 1060s that helped me get under the power limit of the entire house.
