What average speed is the Q6600 hitting when overclocked?

[Mithan]

I was hoping somebody could tell me what the average stable speed that overclocked Q6600's appear to hitting, with the following:
Quality Air Cooling?
Water Cooling?


Basically, what can I expect? I am aware that some chips OC better or worse, hence the average.


Thanks guys.

Between 3.3 and 3.4 on air.

Q6600 oc's seem to be slightly better with P35 motherboards. I was able to go from 3.0Ghz to 3.3Ghz simply by upgrading from a Gigabyte GA-965P-DQ6 to an Asus P5K-Premium. Everything else was the same, but the P35 chipset allowed me to gain an extra 300Mhz. This is with a B3 stepping quad. The G0's are probably averaging a couple hundred Mhz more on air.

I would guess air cooled (with a good hsf) averages were something like 3.2Ghz for a B3 and 3.4Ghz for a G0. 3.0Ghz on a B3 and 3.2Ghz on a G0 seem to be almost guaranteed, especially with a P35 mobo.

Water cooled averages are probably another 200Mhz higher.

I have anti-overclocking case (Silverstone LaScala13) and I got 3.04GHz easily. Haven't tried to go higher yet...

It depends on a lot of factors (obviously). One main thing, though, is the quad core temperatures. While you may be able to pull 3.4GHz easily with a Tuniq on your E6700, the Q6600 may run into temperature issues before then.

Overall, from what I've read, I'd estimate the average overclock on air is 3.0-3.2GHz, with closer to 3.4-3.8 on a good water system. Most of these (I believe) are the new G0 stepping. The older B3 stepping may be a bit harder to coax up that high.

Any chance this is Mithan from VN?

generally for 24/7 operation and with a good motherboard you should obtain:

B3
3.2 to 3.4 ghz on air
3.4 to 3.6 ghz on water

G0
3.4 to 3.6 ghz on air
3.6 to 3.8 ghz on water

Out of curiosity, and not to hijack the thread, what about the E6750? I'm at 3.2ghz right now at 1.30v. Think I could muster a stable 3.4 without issues? Air cooled. Specs in sig.

I think you could muster 3.6 ghz if you had a better heatsink. If you cant fit the godly ultra-120 extreme, grab yourself an ultima-90 with a good 92mm fan. you should be able to run 450x8 no problem.

The quad overclock thread disagrees with your B3 results.

Theres a lot of average joes in that thread and average joes are not great overclockers. But hey, look at your cpu. 3.3Ghz @ 1.42v. Yes, you are watercooling but you can run a Q6600 @ 1.42v on good air cooling as well, lets say a TR U-120 EX. TBH with you, I am surprised your at 3.3Ghz with water. Are you afraid to throw more voltage at it, or do you have a slacking chip?

Or maybe the requirements for the Quad OC thread is more stringent that the XS standard of SuperPi? A few hours of Small FFTs toast CPUs and reveals even minor instability.

What is even more amazing to me is the TAT can push the temperatures even higher over Small FFTs.

I can take ANY B3 Q6600 on a good motherboard with a Tuniq 120 or Thermalright Ultima90 or Ultra120 and get 3.2Ghz.

It's a matter of knowing how to get it there. The most common mistake is neglecting to check your memory voltage and timings. Then people are afraid to try more voltage. Then they might try like 425Mhz FSB and forget to drop the multi.

It will be stable 24/7 when I'm done with it. Again it is knowing what you are doing.

Uhh excuse me ? My Q6600 on a P5K is at 3150(7x450), and still reboots every 3 days for some reason.I have PC-8000 memory, and am running it UNDER-clocked, and OVER-times (4-4-4-12 rated, running 5-5-5-15) I have a 700 watt Fortron PSU, and Antec 900 case, and a Ninja-sythe cooler. Temps nver go over 68c, 100% full load 4 cores. I defy you to get it better at the stability that I require.

To the OP: Please read the Q6600 overclock thread, no need for this question.

Saying any B3 will do 3.2 is just too much of a stretch for me.

OS has a fit maybe? It is not necesaarily your CPU. Also what voltage you running? Maybe you just need a tad more. Sure temps will be higher but stability can be obtained.

Do note that I listed 3 specific cooling solutions too.

Also a poorly or inadequately cooled PWM area (mosfet) that heats up after constant load will cause instability. It's over at XS, people were saying that no amount of voltage will help. They just crash after more than a few hours of 100% load with a quad. Someone noticed the MOSFET area was really hot right before the error/crash occured.

becides that most people aren't going to build a PC to sit it doing DC all day.

 

[ChronoReverse]

If the OS indeed made a difference to whether it rebooted, then it's not stable by definition.

That said, in his case, he should indeed check the PWM and northbridge temperatures as well as increasing voltages. Nonetheless, there are most certainly Q6600's that won't make even 3.2GHz if using the hard cap of 1.55V.

If using the cooling methods I specified, and a good motherboard I doubt there's a B3 that won't do 3.2 orthos stable.

 

[Amaroque]

I have the B3 at 3 GHz stock Vcore. It can clock higher, but I don't overvolt my CPU's anymore.

I also run my CPU's at 100% load 24/7 (DC).

 

[Markfw]

The Antec 900 case has 2 120 mm fans flowing over the motherboard, and one 200MM exhausting up ! I have the same temps, as my other quad with and open case that IS stable at 3.2. And if I go higher than I am on the vcore, then temps go out of sight. And are you trying to tell me that a Thermalright ultra90 is better than a Ninja scythe ? Or for that matter than any of those is substancially better than a ninja sythe ? (5c cooler)

And if it won;t run 24/7 @ 100% like I do, then it's not stable.... period.

And Win XP SP2 with all the patches, and Mcaffee enterprise 8 is not a stable platform ?

All it takes is one thing to go out of wack and the OS can just decide to restart. It's not even always your settings. And yes the new Thermalright Ultima 90 probably is better than your Ninja.

And you aren't stable, you said so yourself so what is your argument?

QFT. if you cant get 3.2 ghz with a B3 prime95 stable, you either have a very bad chip, or you are just bad at overclocking. If you choose not to, because of voltage requirements or heat output, then thats a different story. but like i said before:


B3
3.2 to 3.4 ghz on air
3.4 to 3.6 ghz on water

G0
3.4 to 3.6 ghz on air
3.6 to 3.8 ghz on water


assuming you have top of the line heatsink (tuniq, TR U120, and so on), and top of the line water. my guideline does not reflect overclocks achieved with stock intel heatsinks or thermalcrap watercooling.

 

[cmdrdredd]

Also something to consider. 12hours of Prime95 is alot more stress than ANY program will do. It produces more heat. So if you can run 12 hours then it's stable regardless if you "crash and restart after days of running DC apps" Windows XP is not a server OS or an OS based on Unix which is crash free. If you were running some other OS and this happened (either a server OS or Linux) then I'd be worried.

Personally I think 2 or 3 days of 100% uptime running 100% loads on 4 cores is pretty damn good.

If you leave windows idling long enough it will eventually run out of memory and crash it self.

Except Vista...I've yet to have any issues in this regard. I dunno if x64 differs from x32 at all this way.

1.42v is the actual, its set at 1.51v.

It will no go beyond that point prime stable, and i know what im doing.

If youre talking about lame ass XS suicide runs, sure i can run 3.6 or 3.7 for 15 minutes and get a screenshot of doing Pi if i try 3-4 times. However, i dont waste my time suicide benching and use my machine to do things other than artificial benchmarks.

Call us "average joes" if you feel better about your magic unstable OC, but dont lie to us about the averages when we are talking about different standards of stability.

There are people running these prime stable at 3.6Ghz you know...
