Overclocking a Q6600

Silenced · 19 May 2009 at 17:37

Hey OcUK,

I'm thinking of overclocking my Q6600 2.4GHz, currently it runs at a max temp of 45c. How much GHz could I get it to before reaching a temp that wouldn't be good?

You can't give a definitive answer to that. You have to try yourself. Increase the fsb untill it becomes unstable or the temps get too high.

check the VID of your chip and report back ?
mine was a 1.3250v VID, only went to 3.4Ghz stable and 3.6GHz on bencies but wasnt stable over long periods.

Got my Q6600 running at 3.0Ghz at stock volts with minimal impact to temperatures. Max temperatures about 60-65 when running prime to check if your overclock is stable.

Mine's at 3.2 on 1.224v and it only gets to 70 degrees peak on intel burn test. Rarely see it above 55 in normal use/games

what cooler please?

we need your system specs to tell you the answer

the motherboard your using would be a great help, that way as rjkoneill suggests we can give more specific help

There really is a huge variation with the Q6600s
Mine is 1.325 VID, and to pass 24 hrs Prime95 blend I need a BIOS setting of 1.38v. With vdrop+vdroop about 1.30v according to CPU-Z under Prime
With the Freezer 7 Pro, it was hitting max 62C core temp with very small FFTs but with the larger ones around 58C or so. I'm not sure if 1.38v is safe long term, I guess so as some people put a lot more through than that, but always a risk with overclocking

1.38v is fine

you are pretty much safe up to 1.6v as long as you can control the temps, I have not seen a Q6600 die at these volts yet

Yeah, there is a huge variation. Mine needs ~1.5V to be stable at 3.4GHz

When i was running mine. at 3.8ghz i needed 1.50625 in bios (1.512 @load), could probably have clocked it a bit more with more powerful fans or water as temps may have been the limiting factor.

ye i needed 1.488v on my Q6600 @3.4ghz to be stable
and wasnt stable past 3.6Ghz

Pneumonic · 20 May 2009 at 23:45

For 8 hours prime-stable mine needed the following vcore (all load):

3.6ghz = 1.344v
3.75ghz = 1.424v
3.825ghz = 1.496v
3.9ghz = 1.496v
4.02ghz = 1.536v

I could superpi @ 4.25ghz @ 1.6v

To get an idea of vcore you want to look at this thread: http://forums.overclockers.co.uk/showthread.php?t=17779323

specifically this post: http://forums.overclockers.co.uk/showpost.php?p=12164840 you need to keep in mind current Q6600 don't clock as well as some of the early batches

You get rid of the q6600 pneumonic?

Pneumonic · 20 May 2009 at 23:49

yeah I sold it on MM a few months back (got a good price to!

)

Am just messing around with an E5200 at the mo until I have enough time to start my new project

setter · 20 May 2009 at 23:52

Yep, got shot of mine as well on MM, bought a q9550 to have a play around with, bit of a crazy upgrade but i fancied a new toy.
