Yep, I am another
crypto currencies miner. But in all truth, I find the hardware challenge more fun then the bitcoin stuff.
Power is not the issue (any more). I have 2Kw worth of PSU. 2X HP Common slot 750W PSU + Thermaltake 500W PSU. Currently, with all 8 cards running full tilt, across two motherboards, and I am drawing 960~1000W. Those numbers are according to a Kill-A-Watt meter.
Hardware wise, this is all x86_64.
Arthur: Thanks for the details. I have a board that with give me a "missing memory" beep code with more then 6 GPUs. Now I understand why!
How can I track down how much system DRAM a GPU is using? These are all the newest Nvidia Pascal based cards. Mostly GTX 1070's.
On an interesting note, one of my oldest motherboards, a Gigabyte GA-970A-UD3 will boot with all 8 cards, but gives me the no VGA beep code. Serial console for the win!
Is this just a BIOS level issue? Or is there some hardware component I should be aware of?
Thanks for the help.
