Negative temp!

[cherno666]

I just tried to use core temp (version 0.95.4) and i get a temperature of -49 degrees....

My cpu is a Mobile Sempron 2800+ (a HP nx6125 Notebook)

Any ideas?

Interesting.
What windows version are you running? XP\Vista? 32\64bit?
Can you please post a screenshot?

There goes the screenshot:




I'm running Windows XP Sp2 32 bit

That's weird.
I guess that this CPU may not have a DTS.
It'd be very helpful if you could send me a "Register dump file" that CPU-z (http://www.cpuid.com) produces. I'd be able to see what the exact problem is.

That's strange. From the dump I can tell you the temp was 52C when you made it. Could you run Core Temp and while it was running make another dump file and post this part here?

Things are getting really weird.....

I started core temp and.. as usual -49º, but when i started cpu-z.... core temp begins to show me temperatures of 50º (+- 3º)

And when i close cpu-z, core temp is back at -49º

Maybe my computer is possessed!!! (That would explain a lot of things....)

Just kidding, but i recently had an mayor overheating: The cpu fan, for some unidentified reason, didn't start when the temp was raising, so my cpu reached the 80º. I feared that the sensor was burned, but it seems that is another problem...

PS: Sorry for my english.... my grammar is a disaster...

Ok, thanks for the info. I'll talk to Franck (CPU-z author) and see what is it that he does to this register that magically causes it to stop working.

I will also edit your post with the txt dump as its huge and makes reading the thread hard.

[cherno666]

Thanks for the fix!!!!

[The Coolest]

So is it working now?

[BadBoyNDSU]

I'm seeing this same issue with the negative temp on a Sempron.



WinXP SP2 32-Bit

[imposter]

Strange how amd's only work from -49C to 206 lol.

[cherno666]

Maybe my answer is a little late... but is working ok now. Thanks again for the fix

[The Coolest]

If anyone still expiriences this problem, please try the new beta version.
