I have a reocurring issue with my mining rig. Every time I restart the system the mining rig runs at full capacity at 145 MH/s. [6x GTX 1060] After a while (usually few hours) GPU no 1 drops in hashrate by 25% and the rig's hashing power drops to 140 MH/s. [see picture attached ]
I am using MSI Afterburner and I can see one of my GPUs returning to default setting randomly and I have to set it manually to my overclock setting. Once its back to my overclock settings it will stay there for a few hours and reset itself again. If I leave it running the whole rig becomes unstable within 24 hours and I have to restart the system again.
What could be causing it? Bug in bios/afterburner? I tried different overclocking software.
Is there a way to program restart every time the hashrate drops without having to do it manually?
Many thanks. K
