What's a good OC for a q6600?

I hit 3.6ghz without a fuss and I'm going for 4ghz.
If I recall most q6600 would have problems past 3.4ish. Is 3.6 out of the ordinary for a q6600? What about 4ghz?


Thanks.

A G0 Q6600 could hit 3.6+ easily on a good motherboard with a good PSU. The first stepping was the one that gave out sooner. Which one are you running?

The one I have at work was working at 3.6 for about a year but later was crashing at anything above 3.2GHz. Average was about 3.6GHz on these chips but a lot depends from motherboard as some simply don't like high FSB.

I thought so, I think it's a g0 I'll have to double check.

I traded a q6600 for a i7 965xe here. That q6600 did 3.4 at stock volts and 4ghz at or just under 1.4v. I had a couple of others that easily did 3.6 and with a little work 3.8.

Intel Core 2 Quad Q6600 G0 #1 overclock settings
VID: 1.325v, (date code: L804)
(actual voltage) (voltage set in bios)
3GHz (333x9): 1.25-1.31V (1.35625V)
3.1GHz (345x9): 1.296-1.38V (1.41250V)
3.2GHz (356x9): 1.38-1.44V (1.48750V)-G33M-DS2R 1.368-1.424V (1.46250V)-EVGA nForce 780i SLI
3.3GHz (367x9): 1.432-1.480V (1.51250V)-EVGA nForce 780i SLI

This Q6600 didn't overclock very well, needed a large voltage boost for anything above 3GHz. I had to set it at 3GHz to keep it 24/7 stable with reasonable temps.

This one was a great overclocker, and was able to run at stock frequency at a very low voltage (below 1v). Able to reach 3.4GHz for a 1GHz overclock at stock voltage. I ran it at 3.5GHz daily for a while, but ended up having to lower it to 3.3GHz for 24/7 usage because it ran too hot and would occasionally crash on hot days during the summer months if the A/C wasn't actively cooing the room it was in.

I'd say 3.2-3.4GHz is more common. And 3.5GHz+ is achievable for better CPU's, though if mine is any indication they will run quite warm, even if stable. I was cooling the chip with a Cooler Master Nepton 280L, which is no slouch when it comes to cooling, but it couldn't really achieve temps below 60°C when I went above 3.4GHz. I would have preferred temps of 55°C or lower, but that wasn't really possible.

4GHz doesn't seem likely for a Q6600, assuming you're running air cooling. 3.8GHz would be amazing to me, because I have an amazingly good Q6600 and never hit 3.8GHz.

Mine's like the first one. :( At only 367 Mhz FSB, it likes to chuck bus error machine check exceptions with blend Prime95.

Mine is being held back by the nb in my system. It's a ddr3 board and it can't handle the ram with the oc and the gx2 gpu.
I bought some lowend simple ram and I'm waiting on some low end gpus. Hopefully that will let me hit 4ghz. I think a pci gpu would help too. But I can't bench at 4ghz. It's hot as it is right now at 3.8. I hit 3.9 too but I could not get it stable, heat is getting to it I bet.

My first 2 Q6600's were run in a P5K Deluxe wifi, and the rare gem that was my third Q6600 was run on my Rampage Formula. Both of them are great boards imo.. :cool:
