This period I am testing my first 6x1080 Ti mining rig. Everything was working fine (4300 sols) for 4-5 days until today. From the 6 GPUs it seems that only 3 work. All connections from 2 PSUs are fine, risers are OK, PSUs "test" (fan test) is OK etc. From the 6 GPUs none has lights on the brand (ASUS) as they used to have. Also only 3 of them have working fans and only 3 "blow" air (but not hot as they used to be). Lastly I can not connect my monitor using an HDMI cable as I used to do my monitor erros says "no video input"
I had in mind a PSU error but as i mentioned before, "test" (working fan) is OK.
