My rig show only GPU0 and GPU1 temp and fan, i have 2x 7990, under win 10, already tried all from catalyst 15.12 to 17.1(used ddu), tried all sort of config command(-asm 0, -tt 75,75,75,75 -wd 0).
I'm worried because i used the command -ttli and -tstop to protect the rig, but that seems to affect only gpu0 and gpu1, already see gpu2 and gpu3 get to 100 celsius....
Already tried miner 10.0,11.0 and 11.1
Any tips?
7990 auto shutdown @ 104°C anyway but if your card is getting that hot you need to rise it out of the case.
If you are already using risers then you should apply new thermal paste because I have MSI 7990 mining stable @ 69°C
Much simpler to solve the cooling issue than your question.
