Thank you for your reply.
First i moded the 570 cards like rkulov said. After trying the settings from verbl-kint, that didn’t worked, i just tried yours. Sadly now none of the cards get a hashrate anymore. Maybe got an idea whats the problem?
Also one of the 580 cards went offline over night, “autofan: gpu temperatur 511 is unreal, driver error” does someone has an idea, what the problem is?
