Rig used to work 247 but now doesn't. GPU 1: detected DEAD TRM

[oscaralfons]

My rig was really stable and used to be working well but now it doesn’t work. Rig starts and and after couple of seconds it gives me error ( GPU 1: detected DEAD) and goes offline. I haven’t done any modifications or changes to the rig. Tried with and without OC. I have 1x 860w platinum and 1x 760w platinum PSUs. I tried changing gpu and risers and that doesn’t help. Changing miner also does nothing. Sometimes after reboot, rig doesn’t detect all cards.

Rig:
1x 3080
2x 5700xt
1x 480
2x 1080ti
2x 1060

Asus PRIME Z390-P
8gb ram
240gb ssd
1x 860w psu
1x 760w psu

not enough voltage, or too much memory is usually the cause. adjust whenever you get the error

I tried setting default voltages and got same error.

Default is generally worse off than proper clocks.
