I have a rig running with Ubuntu and 10 GTX 1060. I had properly configured the whole thing and everything was fine until recently I discovered that the last GPU was not overclocked. Forcing it through nvidia-smi doesn't work, it ends up with an error message.
I have configured all cards to use Coolbits 12, I have used the same xorg.conf file since the start but now when I look at my Nvidia xServer, I see that there is one screen missing and the last GPU is using the default clock speed.
Do you have any idea of what may be wrong?
