Mixed rig rebooting after 5 minutes

Hello Everyone!

I have two mixed rigs, one with 8 cards and one with 6 cards, the one with 8 cards runs smoothly, but the 6 cards one reboots after 5 minutes or so, I don’t know what the reason is. It mines normally in the beginning, like you can see in the picture, but as you can see in the messages, it reboots a lot, just to be sure I turned watchdog on, so it won’t mine 0 after a while (which also happens).

Things I have tried:

  • Removing the OC’s → won’t turn on at all
  • Change from beta to stable version → I did this too, and it wen’t from mining 1 minute and then rebooting to 5-10 minutes mining and then rebooting.
  • Try different miners → TRM worked best

I know I haven’t tried a lot of stuff, but I am quite new to mining (2 months) so, if anyone could help, that would be great!
