i got 12 gtx 1070 EVGA SC2, all my cards have ETH 31MHs but the last one has 26MHs... what could it be ? I used same setting for all. This card did 30 on windows...
What brand of 1070? Also what's the powerlimit for that card?
EVGA is the brand
I set power 151 , mem 1400 and clock 100
I had that issue but that's because I was running the PL too low for one of my 1070s. After bumping up the PL to 120, it hashed at 30 mh/s no problem. What type of PSU do you have running these cards? Make sure there is enough juice going to it.
I got all different sorts of 1070 running at 100W, with memclock at 1200 and coreclock at 150. Only a few had to have slightly higher power limits, but the majority worked great. 30.6 MH/s average rate and very power efficient.
