q6600 Prime32bit Stable, Prime64bit crash

wuyanxu · 18 Jan 2008 at 10:36

i've managed to get my unlucky q6600 very stable at 3.2Ghz, 400*8. it is able to complete Prime 32bit for more than 10 hours.

but when i run Prime 64bit, it fails after 3 or 4 hours. do i need to add more Vcore??

also, i've booted into Windows with Vcore of crazy 1.72v. and ran SuperPi. my Vcore seems very high compared to other q6600 overclockers. is it because of the unlucky q6600 with 1.325VID??

64bit vista? or windows xp?

if vista try with----> open cmd as admin-- type net stop audiosrv and try after that. when done net start audiosrv

Keep an eye on those PWM temps, 70C wont help at all. Looks like you have C1E enabled as well, turn it off for now.

Take a look through my bios settings.

superb overclock. you've got active cooling on chipsets? im scared to increase those voltages any more.

so to solve PWM temperature problem, i need to up GTLREF to 70%, and then i can decrease VTT from 1.31v to 1.27v??
i thought maximum temperature for PWM's are 100c. and the high temp for that screenshot because i was burning 8800GTX at the same time, i didn't have a exhaust fan for GTX (you know, one of those PCI slot exhaust fans) so when burning the GTX, general system system temperature raises 5c.

also, sometimes it restarts (i guessing blue screen) does that mean my RAM is set too high? but Memtest86 was fine with exact same settings.

what's audiosrv?? why does disabling it make overclock more stable? im running 64bit Vista.

I have a couple small 40mm fans on the NB and a 120mm blowing over the PWM area from the side, all temp controller from the bios. Ive also replaced the stock TIM with decent ceramique and bolted the Heatsinks on instead of those push pins. Once the PWM goes over the 60C it will effect the overclock I've found. Forget what they can survive. They'll take the temps, just makes things unstable. The GTLref I found made my Q6600 stable around the 4GHz range. Try from 67% - 70% see what it does for you, 67% on mine caused instant restarts.
