i am about to smash one of my mining rigs to bits. it's perfectly stable all day, but freezes or shuts down during the night. so i'm losing hours of mining time each 24 hours. stupid problem. i tried different risers. setting higher virtual memory. temps are fine as i've installed much higher rmp fans on all the 6 cards. they never go above 75. during the day i have the garage door open and the ystay around 55/60. 75 is not high enough to cause freezing. as i said they mine all da yever yday fine. it's jus tat nioght when i'm asleep. it's like it knows i'm not watching
Had similar problem. It's just randomly shut off. Could go for days, sometimes hours.
Switched out risers and all that, no luck. Started disconnecting cards until it was stable. The "bad" card, I just tried by changing the port on the motherboard and after that it was all good. So it ended up being the mobo port that was the culprit.
