***The Official Q6600 Overclocking Thread ***

danza said:
I've decided to try to OC my Q6600 some more. I bought this thing about 2 years ago, and straight away had it running at 3GHz (333 x 9). It will run at that all day, every day on stock volts (about 1.25 according to CPU-Z), even though the VID is 1.325. I've tried upping it by just another couple of hundred MHz, but not had a lot of luck so far despite enabling LLC and upping the volts to 1.325. However, I'm starting to think it's worth trying to eke out a little more from this thing and trying higher voltages.

Currently seems quite stable at 350 x 9 on 1.33 ish volts, but time will tell. Temps are hitting 66 on one of the cores, is this a little high (bearing in mind that Prime95 will get higher temps than every day gaming and normal use)?

I'm only using an Arctic Cooling Freezer 7, which I think is a bit pap. Maybe i should consider investing in something a bit bigger/more efficient...

you should get higher fairly easily.
i take it this is a G0 revision? (cpu-z tells you this)
i have a hotter and more power hungry B3 revision Q6600 currently at 3.4ghz with 1.4v.
the Q6600 is fine upto 1.5v. and the top temp on mine is 80.c, as i found out when it shutdown at that temp ;)
you are right regarding prime, and Intel burn test is even hotter,
when stress testing, i dont mind letting it get in the 70's.C, as day to gaming it is usually in the mid 50's.C.

bump the voltage to 1.4v and then just keep raising the fsb in 20mhz steps and stress test between every jump.
have you 2 or 4 sticks of ram? if you have 2, then most mobo's you may not have to raise NB volts, if you have 4 sticks of ram, then raise the NB voltage a couple of levels.
also dont forget to either leave ram at 1:1 ratio, or unlink the ram, so it stays at its stock speed, this way it does not interfere with the cpu overclock.

also what mobo and ram have you?
i used to have tuniq tower 120 and my temps as i said above used to get high, now i have a Noctua NH-D14 and it did drop my temps, also when i do upgrade, i know it should fit the new cpu socket as well

Right, I'm running a G0. It's now at 366 x 9. VCore is at 1.375 iirc (away from PC atm) and it's stable in Prime95 and Intel Burn Test. I tried upping to 3.4GHz, and it wasn't having it. Voltage had to be increased to ~1.4 for that extra 100MHz, so not worth it. My mobo is an Asus P5Q SE Plus, so not the best in the world. RAM is OCZ Gold or Platinum PC8500 (again, can't remember which), 2 x 2gb sticks. It's running at a tad over 1100MHz.

I might try upping the NB volts a notch or two and give it a few more MHz and see what comes of it when I get home later. Also will try lowering the RAM to the next notch down.

its worth a try raising the NB a level or 2.
also change the pci-e frequency from 100 to 101,

My chip does not like it over 3.0ghz with a x9 multiplier,
but i changed it to x8 and got the fsb upto (425 x 8), so it may also be worth trying this as well. (try the link first)

here is an excellent guide, he is overclocking a Q6600 on a asus p5k mobo which is a P35 mobo, but most of the bios options will be the same on yours.
also as yours is a P45 mobo, it will be good for overclocking ;)

edit. also a similar thread in the overclock forum running now.

here are Setters' settings for 3.6ghz
"My old 1.2750 vid q6600 hit 3.6ghz on 1.400v on a p5q deluxe, 3.8 at 1.512v iirc, fsb - nb strap at 333mhz, 1.58 cpu pll, 1.34v on nb and fsb termination, (vtt). "

I don't seem to be able to get it stable at sensible volts (read sensible temps) at anything over 3.3 GHz atm. I quite happy with that for the time being until I get a better cooler. I lapped the CPU yesterday (heatspreader was nowhere near flat), and also lapped the Freezer 7. Took temps down a few degrees, but I'm hitting 77C+ with the side off my case gunning for 3.4GHz+. 3.3GHz just seems right at the mo. Buggering about with the NB voltages seems to do little apart from make it very much hotter than when it's on auto, easily 70C.

I also realised just how damn noisy my Freezer 7 is too - definitely want something quiter now!

My freezer 7 (rev. 2) is absolutely silent, even on full load.

At 3.4GHz I hit about 73c during IBT. With an up-time of 234 hours, real temp shows a max temp of 49c during that time.

I don't worry about stress test temps too much, as general use never sees it that high anyway.

For what it cost, I am very impressed with my Freezer 7 to be honest.
 
Guys, OC noob here, some advice please.

I'm trying to OC my Q6600, I guess, as far as I can for experience more than anything.

I've been using IBT and Real Temp to do a quick check of stablility and monitor temps when changing settings. Doing anywhere between 1 and 10 passes so far.

Am I right in thinking that IBT will raise temps to about as far as they will ever go?

Also, is 3DM06 a reasonable benchmark to use to test likely gaming temps?

Finally, I see references to "LLC" in respect of some Asus boards and how it can help with higher overclocks. Is this something I should looking to tinker with if trying to hit 3.6?

Thanks.

never tried that, or why not try a game benchmark like crysis ot metro2033

afaik yes,
check that link in my previous thread for a good explanation of all the bios names/settings.
but i dont see anything about LLC in that link.

there is also loads of excellent info and settings in this thread, but it is rather large ;)
