***The Official Q6600 Overclocking Thread ***

Phunky said:
Yeah - you guys have just confirm what i thought.

I seem to have gotten my hands on a decent Q6600 (i think) its VID is 1.285 and it runs fine at 333x9 without touching any volts at all on all three of my boards listed above.

Temp's also seem good im using the Noctua NH-U12P which seems to keep things around 32c idle and under 49c under load - although i've not really kept my eyes on temps that much as i've not been able to push the CPU as i thought.

I'm look at going with the MSI P35 Neo2-FR and will be sticking with my OCZ PC6400 - think this will manage 3.4ghz +?!

Good G0 Q6600's commonly get to 3.8Ghz on that MSI board with very very good air or water, its a stinkingly good board for the price.
If your Q6600 does 3Ghz on pretty much stock vcore it will fly on a decent P35 board :)

My Q6600 goes to 3.8Ghz with room to spare but needs 1.5v to get there and also remain stable. I can't recommend this board enough.

@ Hethers sorry to hear about your dad. :(
 
How do I tell what the VID is on my new q6600? With the Vcore set to auto, it reads about 1.16v in cpu-z at idle. I'm stuck on the stock cooler untill my Ultra 120 Extreme arrives tomorrow, but i've got it running at 3.0ghz with a bios set vcore of 1.2 (showing about 1.16 idle/1.13 load in cpu-z). I tested it for over two hours on prime small ffts and temps maxed at 65. I obviously don't want to push it any further until my REAL heatsink arrives, but do you think that I may have a good chip by the fact that it will do 3.0 on 1.2v? Here's hoping anyway :D
 
I OC'd my new Q6600 for the first time a few days ago. Upped FSB to 333,putting RAM at 1:1 @ 667mhz. An easy 3GHz. NO change in temperature or stability whatsoever, ran both OCCT, then Prime95 for about 5 hours, all passed, and i don't think i saw my highest core temp (the temperatures on my cores vary by ~8C) get past 52C. Sits idle at just over 30C (Edit: that's after i've been playing Crysis and i'm browsing actually heh)

Dunno what the crack is changing all the vcore, i shouldn't need to touch it, though i think it's actually at around 1.3v on auto, so may be why.

yup, if set to auto your board will up the vcore from stock voltage when you go over 300ish fsb.
 
From what i read, with my spec, i should hit 3.6 Ghz without breaking a sweat with the vcore at around 1.38v.

Imo, 3.6 is the golden standard for me, runs the PC6400 ram at optimum with ratio 1:1.
 
As i've stated in previous threads, my Zalman is the boy, it'll walk it :D

Yet to see this break 50C under 98% load (don't ask why it won't go 100%, i don't know heh, though that is OCCT)

Infact, i'm quietly confident it'll push past that...oh crap that would mean i'd need faster RAM, as i don't think you can have it where FSB is higher than the RAM divider, like 6:5 can you and be that stable? I assume it would require my FSB frequency to be like 450mhz, which is kinda hot.

Lets see what your Zalman cooler has to say about that :)

...He didn't say anything but I just saw him driving off at high speed.

(not a chance)

I've found from talking to a few people and I'm sure its been said already, that these Q6600 chipcs almost don't seem to have a "wall". That is to say, you pump enough vcore through them and they will go to ANY speed your cooling can handle.

The only difference from chip to chip is where the base vcore required starts at.

For example, my chip is a rubbish one and has a VID of 1.325v and somone else might have one with a VID of 1.225v. So if I want 3.6Ghz I'll prolly need around 1.5v and they will need around 1.4v...

Now if you've got the cooling you should still be able to get the crappier chip to 3.6Ghz.

Would that be roughly a correct assumption to make? I noticed back in the old days overclocking a 4000+ Sandiegao AMD chip that there was a "wall" at 3.2Ghz-3.3Ghz (all of them were like this pretty much). I had a Vapochill LS at the time and still only got mine to 3.2Ghz....

I got rid of that a while back and went back to air, was still getting 3.15Ghz....
 
Dammit, i'm going to pull up a comparison table in a bit and show you that lil' Zally is cool! :p.

Of course Heatsinks like the Thermaltake 120 Ultra will be a bit cooler, as it's the size of a filing cabinet lol.

Also it didn't need lapping as it comes pre-finished, it's like a mirror. I didn't clean the surfaces properly though and put maybe a little bit more grease on that i should have (thin layer on both surfaces rather than one), so could probably get more from it.

Dunno what my base vcore was, but on auto, after upping FSb to 333, i think it sits at 1.38v, will check when i finish "work" lol.

The old amd san diego and toledo cores were quite odd, some loved high vcore and scaled well and some didnt. I found them to be very temp sensitive, the dual cores more so.

But with regards to these intel quads I think on the whole even if you have a good chip you will get to a point where to get an extra 100Mhz you will have to crank up the vcore regardless of how good temps are. I think they do have a wall so to speak.
 
Dam right. Just got home, my vcore is at 1.41v, dammit!

It's set on auto,so now to painstakingly move it down a notch at a time.

Though that's not as annoying as this:

Asus Prode CPU temp: 22C

Core Temp:
Core#0: 31C
Core#1: 27C
Core#2: 21C
Core#3: 25C

Researched this a lot, seems it's the luck of the draw, like the vid. Most get a variation between cores of a few degrees, a few get a huge variation like me, and it has nothing to do with the seating of the heatsink or the thermal paste either.

poo. :(
