Really weird temps with 4850

[John Venture]

Hi, I was using GPU-Z with a stock 4850 and it was fine (70° idle, 96° load).

Then I mounted an accelero s1 rev 2, with 2 120mm fans blowing full force on both sides (1 in front, 1 beneath)

And then GPU-Z gave temperatures of -4° for gpu, 508° (yes 508) for dispio and shadercore and 0° for memio.

In hwmonitor, the program gives me a 128° (and it stays there).

I've touche the back of the card with my finger and it wasn't hot, nor were the VRM or the ram chips.

Now I realize I might have screwed up something while mounting the aftermarket cooler (although I was very careful not to screw too hard), but do you have any idea why I get such weird temperatures, and so different between the 2 softwares?


I've logged it if that's any help (second batch comes from another 4850 and it works fine):

Are you running the latest version?

Otherwise try reinstalling GPU-Z.

 

[John Venture]

Yes, running 0.3.0.

And when it was working (before mounting the aftermarket cooler) it was the same version.

 

[King Wookie]

Hmm, sounds like a corrupted file or such.
Don't know if anyone else has any insight.
