After long time one of my AMD cards crashed.
I had -tt 55 -fanmin 55 -fanmax 85
And log crashed shows me that fan was 0
I suspect that temperature was too high (though was night) like 58-60 degrees and having fanmax 85 coupled with undervot made the miner crash. Is it possible ?
well, it can be anything, not just temperature
The best way to find the cause is to go through the logs, just before the crash and see what caused GPU crash.
