Amd 7990 temperature

[Stalker_PY]

Hello guys im having some really strange temperatures with my amd 7990

 

Like 2 days ago y change the thermal compound from the card and I can swear that yesterday the temperature of both gpu was kinda the same (Like 45 to 50 degrees in idle and like 80-85 degrees gaming)

 

But today i see that the first gpu is about something like 63 degrees Celsius and the second one is at 48 degrees

 

Here you can see it the difference in GPU-Z

 

 

I dont know if it is because of the core clock difference or what, but like i said i swear that yesterday both of them where the same temperature

It is because of the voltage difference. The left has .95V and the right has .85v.

It might be the zero core or whatever, where one core turns off under light load and idle

or that

agreed,

 

also noticing that the core clock and memory clocks are noticeably lower on the cooler silicon.

today I realized that my BIOS was reset, I do not know if it could be because of that ??? because i didnt change the voltage of any of the gpus, I don't even think about doing that, knowing that this is a very hot video card

 

so i should change the voltage to .85v???

[bgibbz]

Voltage should be set automatically, unless you change them yourself. I wouldn't worry about it. Either card is over heating. Just leave it alone.

i just restore my system from an yesterday point ,and now both gpus are at .85v, and both have the same temperature 

 

Thanks for the answers
