I have 8x 3080 DDR6X and get between 96 and 99.8. I can’t get them any higher without it crashing at some point.
anyway point i am going to make is that each card performs differently with the exact same settings. this could be heating from the exhaust of one fan onto another card but i don’t think so. more likely degradation of the paste or just something inherent in the silicon somewhere.
I set min fan to 55% and the auto fan to take those that need it up to 90-100%… I’ve tried autofan with a lower setting and it doesn’t work for me. High auto fan usage then gives me some indication which cards are struggling.
my 3x best cards clock stable to MEM2400 and CORE1050. @99.8
all the rest i have on MEM1800 and CORE1030 and they are all stable at about 96.9
ambient room temp is about 23 celsius and i have 8x extra fans across one side of the rig and the 2x PSU venting to the underside of the outer GPUs
I want it all to go higher but have given up. what i have is stable and i think that is more important. at least until the warm weather in 2022 !!
