What's a good OC for a q6600?

[saturn]

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?

X48 motherboard did great with those CPU's. Those CPU's were FSB chipset limited.

Mine topped out at 3.8 for 24/7 reliability and would bench at 4.0 GHz

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.

 

[Witchdoctor]

yea, when mine was on ambient cooling I was using a Asus P5Q Pro , it was running the P45 chip set

I got better results on my x38 Rampage Formula , 4.3 and change on single phase, good memory was a must have at 480

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

 

[wagex]

what board and stuff are you running? is this the rig from your other thread?

edit: i just seen you edited the other thread and got it working yay!

 

[saturn]

Yes it from my x48 lanparty system.

Good stuff Saturn. Glad you got 'er up and running.

I am too, that was until I was reminded of the headaches caused by 775 motherboards with award bios.

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.

HAHA, I had too.


Award Bios are nice and all, but you sure can get lost in there.

Great, now I'm nostalgic for my old P5Q-EM and Q6600 (which was at 3.6 IIRC)

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.

I been benching at 3.8ghz at 1.45v on air. But it's worm and tosty.

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..
