I bought my first Bitcoins in 2016, observed its ups and downs and got interested in other cryptocurrencies. An interesting alternative to Bitcoin is Ethereum which works, like Bitcoin, on the Blockchain but offers more functionality like smart contracting and EVM – Ethereum Virtual Machine. More about differences might be found here.
Ethereum may be mined using GPUs on graphic cards. As of 2017, no specialized ASIC miners like the ones used for Bitcoin mining exist. This leaves room for truly decentralized cryptocurrency system when anyone with appropriate hardware may support the network and earn some Ethers. And this is exactly what I decided to do. Yay! 😀
After a week of comparisons and calculations, I came up with the following list of components for my mining rig:
|5x GPU||Asus ROG Strix GeForce GTX1070-8G|
|1x GPU||ZOTAC GeForce GTX 1060 6GB GDDR5 AMP+|
|CPU||Intel Celeron G1840 Dual Core CPU (2.80GHz, 2MB Cache, 53W, Graphics, Virtualization Technology, Socket 1150)|
|Mainboard||Asrock H81 Pro BTC R2.0 Black/Grey/Brown/Red|
|Memory||HyperX FURY Series 8GB (2x 4GB) DDR3 1600MHz CL10 DIMM Memory Module Kit – Blue|
|SSD||SANDISK SanDisk SSD Plus 120GB SATA III 2.5 inch Internal SSD, black|
|Buttons||InLine – Mohterboard Test Kit – Mainboard TestSet|
|Riser 3x||Elegiant USB 3.0 PCI-E Express 1X To 16X Extender Riser Card Adapter Power Cable Mining|
|Riser 2x||PCI-E PCI Express 16X to 1X Riser Card Adapter Extender Flex Flexible Extension Cable|
|Dual PSU adapter||Dkey Add2Psu Adapter zum Anschließen Zwei Netzteile und einschmuggeln zusammen|
|PSU||Corsair RM750x – power supply units (100 – 240 V, 24-pin ATX, 47 – 63 Hz, ATX, 80 PLUS Gold, PC)|
|PSU||Corsair VS650 Power Supply Unit|
|Case||Stay tuned for Part II 🙂|
When I shopped the components, I kept comparing prices on Amazon with local shops and other eshops. The cheaper, the better ROI.
Radeon 580 cards were hopelessly unavailable by June 2017 so I went for nvidia cards which’s supplies started being short as well. I was able to grab last five GTX 1070s and one GTX 1060 in a Czech eshop.
As the mining occurs on the GPUs, CPU and memory is irrelevant. It’s Important to choose a mainboard which supports 6 graphic cards. The cheapest SSD or a flash-drive will do. If one doesn’t want to be turning the rig on by a screw driver 🙂 a set of buttons comes quite cheap. At the moment, I’m using a combination of riser-extender and powered-riser. I couldn’t find a 1000W PSU with a reasonable delivery so I went for a 2 PSU setup interconnected by a dual-PSU adapter.
