temps between cores?

Post by pont »

hi and thats for reading this

i am showing a temp of 10c difference between cores at idle. but under load they seem to both reach about 47c and stay there while running prime or orthos .. is this temp difference normal ? and if not how would i go about fixing it??
heres idle Image

heres load Image

thanks for any help you guys can give........pont

Please Try the newest coretemp. 95.4 But this most likely has to do A poor calibration between the cores

Could be poor calibration or it could indicate that you have uneven contact between your IHS (internal heat spreader) on your chip and the base of your heatsink.

Have a look at my results after I lapped my Q6600 and the base of my U-120 Extreme.

Lapping Q6600 IHS
Lapping the Ultra-120 Extreme

Before I lapped the chip and HS, I had a pretty big difference in core temps when loading with prime95 or 2x orthos: up to 6 degrees C (sorry I don't have a screenshot of this). Lapping the chip REALLY evened-them-out as you can see from the coretemp numbers after the IHS and base of the heatsink were lapped (stressed using prime95 v25.3):

hey guys thanks for the reply

im really sure my waterblock (dd tdx)is setted properly and ive been having this temps since day one with this cpu and the one before it(4800+). im really not sure what i can do. i think it may be my dfi board causing these temp deliverances between cores and i dont really think that my chip is running hot at all but i just worry about it.

all other programs ive used to check the temps always reports the lower of the two temps on core temp,.so i think im fine but would really like your input on this ..thanks for your time

It is not uncommon phenomena on these chips, it could be just bad calibration of the thermal sensor.
