Pushing for higher OC Q66 B3 on a P5K Premium..

post #1 of 4
Thread Starter 
I've been running my P5K Premium (0612 BIOS) matched up with a lapped Q6600 B3 and 2GB Tracers RAM. For the last 5 months or so the system has been running stable at 3.2GHz. I didn't change many settings in the BIOS...

set the FSB and multi: 457*7
vCore: 1.34 (1.36 BIOS)
DRAM frequency: 1146MHz
DRAM voltage: 2.2v
disabled the CPU and PCIE Spread Spectrum options
enabled Load Line Calibration
no changes were made to NB or SB voltages

Now, with a new custom water cooling loop, I want to push the CPU a bit more, I always knew it was capable of more than 3.2GHz but I never needed to push it. K, so right now its looking pretty good at 3.33GHz with the following settings:

476*7
vCore: 1.39v
DRAM frequency: 1142MHz
DRAM voltage: 2.2v
disabled the CPU and PCIE Spread Spectrum options
enabled Load Line Calibration
no changes were made to NB or SB voltages

Rig has Prime 95'd 3 hours stably at 3.33GHz. The CPU gets really hot... too hot. Temps are: 66 66 62 62. I know the recommended temp for the B3 is 62 but I'm not terribly concerned about the longevity of this chip. I think I may try a remount in the near future to see if temps improve. I'm trying to reduce the voltage needed for the chip at this speed... I have Primed the system at 1.38v, but one core failed within an hour. I'm thinking maybe if I drop the vCore a bit, I can stabilize the system by uping the NB or SB voltages a bit... I'm "trail-and-error"ing it right now, lol.

Can anyone give any tip on what to tweak on this board? Thanks
At long last...

Why don't you use an 8x multi?
450*8, 1.45v on the NB.
It's alot harder to get stable with a lower multi.

voltage required for 3.6 would be too high... temps would be waaay above where they are now which is already like 5 degrees too hot.

It'll be alright for stress testing.
Anyway, still try a higher multi.
