Hello, having an issue with T-rex mining ETH on a rig with 6x 1080ti:

20210101 02:04:36 WARN: WATCHDOG: T-Rex has a problem with GPU, terminating...

From time to time it hangs and then nothing happen... it stays like this for hours until I have to manually restart the rig. Isn't there a watchdog who supposed to restart it automatically when an error occur? Thanks!
What version did you use cuda 10 or 11?
Switch to cuda 10 to fix this issue.

Hey... can you share your config/cc it seems that you get almost 90watts with 53MH/s what is your current driver for gtx 1080ti?

I only get around 41mh/s with 150watts.



Cuda 10 I'm using, as far as I know cuda 11 is only for newer NVidia cards.... and it's not working for 1080ti. However I have 10 rigs with 6x 1080ti, only one of them is making this kind of issues.

Config: -a ethash -o stratum2+tcp://daggerhashimoto.eu.nicehash.com:3353 -u [wallet]  -w $rigName --kernel 0 --mt 6

OC:  core +100 / +125 depends of the card;
        memory +600
        PL 210W
and the OhGodAnETHlargementPill activated.

It's not 90 Watts, this is the SW readings.... I get around 1400w at wall for the whole rig (6x1080ti) so I would say 220W for one 1080ti.
