Best OC for a Q6600

Ninja Please! · 21 Jul 2009 at 21:40

Hey mates,
A buddy of mine recently got a Q6600 G0 stepping and I was wondering what's the best OC for air on a Q6600? Is 3.6 pretty much it without wc?

It will depend on quite a few factors, such as, batch the cpu came from, vid, voltage required, mobo, cooler and fans used etc, i had one at 3.8ghz on air, but a member here had one at over 4ghz using delta fans. Most of the last production run chips seemed to be topping out at 3.4/5 ghz on relatively high volts.

Mine needed close to 1.5V to be stable at 3.4 on air.

3.8 is a sweet spot imho.

Mine needed 1.512 vcore for 3.8ghz, air cooled by a TRUE black, normally ran it at 3.6ghz on 1.4 vcore, 3.8 or above seems to be pretty rare though on the later models.

Highest I've seen is 4.2 with water.

Mine is at 3.8 with 1.55v.

The average chip will do somewhere between 3-4Ghz, but most tend to be below 3.6Ghz from my observations (on air cooling, with non ridiculous voltages). Mine stayed cool until it hit 3.2, then temperatures started climbing quickly, and I didn't really want to push it up beyond 3.4, as IBT 64bit seems to get hotter than anything else...and it was getting hot

I got it to 3.6Ghz on a vcore of 1.48v or similar. Make sure you have a good northbridge cooler like a Thermalright TR-05 as my northbridge.

Mine can hit 3.4Ghz on 1.275v but after that a lot more volts are needed, 3.6Ghz needs 1.41v, 3.75Ghz needs 1.5v anything higher than 3.75Ghz I can't get stable. Max I've managed to reach was 4.2Ghz, it boots into Windows but that's about all I could do at that speed.
3.4Ghz is a reasonable speed to achieve, it doesn't bottleneck my 4870x2 at that speed.
