I've got the Q6600 GO stepping SLACR.

With my Asus P5K board I have managed to get mine to 3.6 GHz

with an Arctic Freezer Pro. If its a GO stepping model then yeah I think

3.6 is doable.

I have my Vcore at 1.43 and it runs at 38c Tcase and about 44/45c on the hottest core (Tjunction).

At load (Prime95) the hottest core gets to about 65/70c but I also have a Antec 900 case with 5 fans.

Even at 3 GHz you will see an amazing performance boost and you shouldn't have to raise your vcore much if any depending on what

your stepping is. I encoded I Am Legend for my PSP and it only took ten minutes so if you do alot of video encoding

you will be very surprised at you performance :D

My Q6600 is overclocked @ 3.27 GHz with watercooling.

 

Those are the figures I used in the BIOS :

 

CPU Clock Rate : 9x (cannot be higher)

CPU Host Frequency (MHz) : 365

PCI Express Frequency (MHz) : 100

System Memory Multiplier (SPD) : 2.50

Memory Frequency (MHz) 800 : 913

 

Normal Overvoltage for all : DDR2, PCI-E, MCH, FSB; CPU Voltage

and Normal CPU Vcore : 1.3000V

If it's a G0 stepping then probally around 3.6Ghz easily on a good air cooler such as a Ultra 120, Tuniq Tower, etc. My buddy has a old B3 stepping and he can only hit 3.2Ghz stable and that is pretty much the limit.

 

The Xeon X3210 I have is essentially the Xeon version of the never released Q6400, and the G0 steppings are known to hit 3.8Ghz. I have seen G0 Q6600s as high as 3.8Ghz on air with a IFX-14 cooler (a beastly air cooler...it's :thumbsup_anim: huge.

my q6600 G0 SLACR in a P5K Premium will only do 3.3ghz stable. at 3.4ghz it will boot but apps will segfault/crash or even run slower during bench tests. CPUTest will also fail pretty fast at 3.4Ghz.

 

I've brought my vcore all the way up to 1.4 and it wont make any difference, i know the board is good because i can run it at over 450+ fsb if i use a lower multiplier for 3.2ghz.

 

at 3.2 my temps are at 36-39C, under full load (all cores) each go up to 65-69C after hours of CPUTest.
