e8400 temp 8-10 degree's difference between cores..why?

i have an e8500 and i have a difference of 10C between the cores. it seems that some of the 45nm intel processors have really bad temperature sensors.

i've seen some people who only have 2-3C difference between cores and others like me who have 10-11C. i was planning on returning my e8500 to intel for an exchange but i think they'll probably just send me a refurbished unit, so i think i'll stick with the one i have.

Until Intel explains how the Tjuction works, perhaps then you might have a better understanding why the cores are reporting different temp, since those are based Tjmax temp.

Its better to use the programs that read cores for load temps rather idle.

I've noticed that my E4400 on load will be the same or off by 1 degree.

On my Q6600 2 of my cores are 2C cooler then the other 2 when under load.

Again those are based on a Tjmax. And since I've switched MB, my DFI is acting different the my P6N in reporting core temps. The difference is the same on the cores (2C cooler), but the Tcase temps are different. One difference though, is my old P6N didn't have Thermal Management Control option.

Err.. read that PDF file again.

Noticed that CoreTemp tjmax is 105C. That is wrong since the article says the E8500 should be 100C, which RealTemp was set.

For the Quad, CoreTemp again reads 105C for tjmax. When it says 95C tjmax is correct.

So for as Core Temp being right at default is incorrect. Although you can change the tjmax in the ini file for CoreTemp.

The only advice I can give you, is just go by the Tcase sensor (which is the IHS reading), and don't exceed what Intel's thermal spec is on your CPU.

Again.. the tjmax are different for all those temp apps, and that is why you get different readings. The Tjmax is not sensed by any of those apps, or anything that displays core temps. Look at where you have the program CoreTemp. It should have an ini file. You can manually change it.

Edit:

Try putting -5 where it says tjmax offset. It should read the same as RealTemp, for 95C tjmax.
