hello everyone..
I have a problem (It's a strange problem wtf...) my rig working since 1 month and now i see,
2 of my GPU (I have 8 GPU) the hashrate has loss 5 mh/s (30mh/s to 25mh/s)
i check why. And i see its the coreclock fluctuating everytime. (Coreclock : 1150)
Fluctuating exemple ( 800-850-790-1100-1000-900-1060 etc..)
6 GPU working perfect, without fluctuating and "THIS" GPU change everytime... and the mh/s follow him..
