I have a somewhat strange issue with hashrate on the rig falling on all cards after 4-5 days to the point that rig would freeze. For days it would hash rock solid but then all of a sudden it would freeze itself. I came up with a workaround - set up watchdog to monitor hashrate and if it drops by more than 5mhs whole rig would restart and continue normally. I suspect an issue with a driver but what is the root cause I have no idea. I have tried to lower the clocks and push more power to the cards, changed HiveOS versions but nothing helped. Restarting every 4-5 days is not bad and rig mines fine for months like that but I would like not to hear reboot beep at all.
Here is my rig
