Its why i got my q6600

Do the Quads still have a heat problem-because unused cores don't throttle down properly?

[keithwalton]

I wouldn't know as my Quad is never idle but it is the original B3 stepping so i would assume the issues remain, however with 4 cores folding at 3GHz (25% overclock) core temp reports my cpu's to be between 64 and 66C and my gpu to be 39c (all cooled by the same water).

I believe that an idle pair of cores can go into a C1 state which will throttle back its heat load, however speedstep i believe only works on all 4 cores at once or none at all.

66C on water....YIKES.

[keithwalton]

Thats core temp, which reads the on die temp sensor (same as intel's TAT program) and so temperatures are much higher than normal.
Asus probe reckons my cpu is only 44C or so.

Intels thermal throttling only kicks in at 100C by this measurement.

The TDP of my cpu (105w) is similar to that of the 3.6GHz + single core prescott cpu's (115w) but i have 4 cpu cores and each one of them will give the old P4 a run for its money

100C? Ooh, dat's scary! Also dead processor, methinks.

[keithwalton]

This is actual on die temperature measurements from quite simply the hottest point. It does read alot hotter than what most people are used to thinking as hot. Generally as most measurements are either made from behind the cpu package, or some where on the chip package but not the actual die.
Its a feature intel have had with there mobile chips for a few years and have brought onto the desktop 'core' cpu's

Those temps seem very much inline for Quad cores that are working.
Hey Keith which bios are you running with your Q-core.

WZ

2103 i think, i know there is a newer 2205 out or somthing but that only adds 1333 fsb support i believe so i havent really bothered.
The default vcore for my chip is 1.325v, 1.3625 (i thought it was 1.35v stock) is enough for folding to throw up a fit.

At present im running it at stock voltage just 333fsb the same as the Q6850! (3GHz as well)
