buy all my 7970s are doing no more than 15 per card, maybe my -i is too high for them? (use default -i 20)
or driver is too old? updating the driver now
does ram plays a role in hashing speed? coz my desktop has 32G or ram and only 1 GPU hashing.
what processors do you have in both?
desktop I have a fx8320 which is also hashing @ 6 core for 14.5S/s
4 cards rig has a E2160 that doing no hashing
it's CPU related? I tried to swap a 7950 out with my desktop card and the on in my desktop is still doing 22-28
but the one back to the rig is doing 16-19.....
or does OS matters?
My desktop is running windows 10 while my mining rig is running win 7 both are 64bit
