I know that even lowest cpus work well.
In my past years (at my beginning) i ran windows. 8GB Ram helped a lot starting the miner
and using Teamviewer to tune. When i switched to Simplemining 8GB might not be a must.
But i stay with it on all rigs. RAM is cheap and it might help in the future. Who knows....
Anybody out there running a few rigs, with the exact same GPUs (6 or more) and has one
rig build with the B250c motherboard and can compare the hashrate.
Would love to see a bit data.
So far, i only buy the intel B250c and 4 thread cpus like 6100T and up.
The hashrate of video cards will differ by 1-2%, and the result depends only on you. I never go into the settings for each video card separately, but use the same settings for all video cards in a mining farm.
