so celeron g3900 seems to be fine with up to 3 1080TI or 4 1080/1070 on a windows miner. After that is starts to throttle at 100% CPU load. If you’re running just one GPU any CPU will work.
Linux miner has a config to reduce CPU usage even further
I have 12 x 1080ti.
So to run all and not have 100% cpu usage have to buy a cpu with more cores, right? The maximum for Intel 1151 socket is 8core,so a 6 or 8 will do for 12 gpus? Thank you very much for the response everybody
my 6 1080TI and corei3-8100 get 65% CPU usage. I am not sure if it scales to 12 linearly. So you’re probably fine with just higher clock 4-core like core i5-7500 or core i7 7700 if youre paranoid enough
The things is soon some professional cuda coder will figure out how to offload the CPU task to the GPU efficiently and then higher end CPU will be redundant.
