Hi

I am not sure whether this is normal behavior for a Quad Core CPU or if something is wrong, so please pardom my ignorance on this subject as I have just upgraded from a S478 Northwood!

Anyway here is the story, basically I have a QX9650 running on an ASUS P5E3 (non deluxe and no bells or whistles) running (at the moment) @ Stock speed and voltage.

Both Coretemp 0.95.4 and Everest build 4.2.1233 report a huge difference in temperature between cores 1+2 and 3+4

Basically during stresstesting and/or wPrime 1.58 Core temps are as follows (after 20mins of 100% load).

1 = 49C
2 = 50C
3 = 60C
4= 61C

Any ideas as to why there is a huge temperature difference between the cores?

Idle temps are also different

1 = 31C
2 = 30C
3 = 49C
4 = 51C

My motherboard is flashed to the only BIOS which supports the QX9650 (0703) as the shipping BIOS (403) says "Unkown CPU detected" Please update BIOS from ASUS (although system POSTS, it is unstable)

So, is this normal?
If not any suggestsions?

Thanks

John
