im really annoyed at this.

[cyrusm]

ive been tweaking my quad for some time now, trying to reduce to voltage.
im at 1.375v on the bios with 8x412.5

when i use RMClock (or anyhting else that shows temperatures), there is an unmistakeable 3-4 degrees difference between the first 2 and the last 2 cores.
under load, RMC shows the first 2 squarely at 61 degrees, and the next 2 at 57.
speedfan shows the first 2 at 48, the next 2 at 44
tat shows the first 2 at 62, the next 2 at 57!


what is this?? is there any quick way of fixing it? ideally to bring all 4 cores down to the smaller value?


and another question:
i read on another thread that the fsb of these babies is 1066, and you can easily set it to 1333 for a quick performance increase. when i look in cpu-z, my rated fsb is 1648...
am i confusing something here or am ialready pretty set in terms of fsb?

412.5 is your FSB. Times 4 is 1648. Normally a Q6600 has a FSB of 266.

A temperature difference like this may be the result of unevenly applied thermal paste; you may try removing your heatsink and re-applying thermal paste, and lapping the heatsink if you haven't already.

The rated 1066 FSB is due to the quad-pumped Intel architecture; the native FSB = 266, times 4 gives you 1066. The 1333 reference is from an FSB of 333... 333*4 gives you 1333, which yes, isn't too hard to achieve on the quads. Your 1648 would be the result of a 412 FSB, so yes, I'd say you've gone above and beyond the "easy" point for FSB.

My friend's X3210 quad-core has a difference of 6-7C between both sets of cores. I question how carefully Intel sets the heatspreader on both die, it seems like they don't make as good a contact with one of the die than the other.

A difference between cores is completely normal. Idle I see about 2-3 degrees and about four load with my Q6700.

 

[cyrusm]

many thanks, i understand now.
im just gonna ply away reducing my voltages to as minimum as possible at this point..

 

[RussianSensation]

I am getting a whooping 5*C higher temps on Cores 0 and 2 at idle and 7-8*C difference at load for same cores compared to 1 and 3 :brokenheart::shocked:

...wow
i dont feel so bad anymore lol
