AMD Wierd Temperatures

post #1 of 9
Thread Starter 
My friend has the following CPU CPU Type DualCore AMD Athlon 64 X2, 2500 MHz (12.5 x 200) 4800+. Everest,Core Temp show him Core1 temp 51 Cores 2 Temp 58 and Package 28. Even Bios shows 28. So why are the readings so offf ?
post #2 of 9
By package you mean the "CPU" (not core temp) temp in Everest/Aida64?

Mine does that as well. Running prime the cores get in the 50's, while Aida64 sees the "CPU" as 45c

yes. So wich temperature is corect ? the 28 one or the cores temp ?

I go by the core temp. Usually the BIos is the most accurate temp, but in this case 28c doesn't seem right. I'm guessing it's reading the IHS temp instead of the core temp, but I don't know for sure.

In any case tho, I would say the core temp is the most accurate temp reading in his system.

My friend said when package temp showed 60 degrees the pc would autoshutdown so he thinks that the core temp is wrong and that package temp is correct. Anyone else with this problem ?

Is the CPU a 65nm "Melborne" core CPU?? If so, i've had a similar experience a long time ago. The temperature sensors on die were screwed up and would list the CPU running at ridiculous temperatures, when it really wasn't. This caused random shutdowns and a TON of irritation.

I replaced the CPU and the problem immediately went away.

This is strange. I did it with my system (although 939 socket instead of AM2) but I got similar results.

480

Smart guardian shows CPU temp at 52c as does AIDA64 and the BIOS temp. Core temp and AIDA report the core temp way above "CPU" temp. I would only assume actual core temp would be the number to look at, but I'm not sure how AMD rates they're chips. Are the max temp numbers for actual core temp, or the "CPU" temp?

A lot of Athlon 64 CPUs (Brisbanes in particular, though not exclusively so) are known for whacky temp sensors.

My friend and I thank you a lot for your help. Yes it's a melborne cpu. My friend thinks his CPU is dying because we can now safe to conclude his cpu thermal sensor died or started malfunctioning. Since the cpu has 4 years i think it can still last at least 1 more year or so. I have had a Pentium 4 for 7years+ and it's still going strong.
