Hey, I input new overclock settings

FAN55 55 55 55 55 55 55 55 55 55 55 55

CORE1200 1200 1200 1200 1200 1200 1200 1200 1200 1200 1200 1200

MEM2150 2150 2150 2150 2150 2150 2150 2150 2150 2150 2150 2150

after that half my gpus had hashrates of 30-60 while the other 6 stopped working. I restarted my miner and now none of the gpus are running. tried everything. nothing is working

I am experiencing the same issue. Did you find a fix for this? My 5700XT’s went from 53MH to 100+. I restarted the rig and now they do not hash at all.
