*Official Retail G0 Q6600 Overclocking Thread*

[NBF]

i wouldnt say they are "rare" so to speak... i would say about 8-10% of q6600's can do it

you just gotta test the processors before you settle down with one.

Maybe they send the worst ones down here in South America

Or I'm just too unlucky to find the golden ones

this is relatively recent. i've since changed my timings & clocks slightly, but the voltages haven't changed. here's what in the ss

418x9=3762MHz
1.4550 in bios
1.4200 idle in windows
1.3500 load in windows

seems like my idle windows vcore is about 1.37v? and 1.32-ish under load? can't remember. i'll post a screenie after i get home from work, but my results are basically the same as zucker2k's here. i bought his chip. his board doesn't have near the drop and droop that mine does. oh, and my temps are about 5C higher I think. more later...



edit: his screen shot is an attachment and didn't copy into the reply. here's his post with screenshot

I wish my P5E would let me run anything other then 1:1 over 395mhz

It's probably your ram. What VNB are you running at that speed?

P5E doesn't have a sensor, so I couldn't tell you the VNB. Right now it's on auto, but I have tried bumping it in the tweaking process. I had no trouble with the RAM divider when I was running the E6750, this is only on the Q6600.

Really?! It's not in the bios? Under "Power," "Hardware Monitor"?

Nope.

I just ran another 24hr p95 torture test on the cpu, this time with the ram overclocked:



This is the most stable cpu I've ever had....it almost makes me want to go for 3.6ghz

That seems like way too much Vcore for 3400mhz. Have you tried priming with a bit less Vcore? What are your temps like?

[aussie-revhead]

My current q6600 needs more volts than that to be stable at 3.2GHz !!!! So that one isnt too bad .

[Prodigys]

Got my old QX6700 ES plugged in, it is fully stable on 340 x 10 with only 1.33V...
And remember this is a B3 .

It does 4Ghz on only 1.51V .

Hello, this is my first post here and I would like to share some results and get some help. I have tried the vdroop mod in my p5e and now I got some confusing results with the vcore of the quad. Before the mod, at 9*333 the q6600 needed 1,264v and 1,224v in idle-load to get stable with prime95, and now needs only 1,200v that is the same in idle and load after the vdroop mod, so I thought the same should happens at higher speed and the quad should need less vcore but don´t.. At 8x400 before was 1,288-1,248v and now is stable with 1,264v, and at 8*425 before was 1,376-1,328v and now needs 1,352v, so the temps under load are a bit higher. Mayby someone here have a similar issue and know why this happens. Thanks in advance

[Celcius]

Under load the vcore goes down to 1.360v. My max load temps are in the 60's (hot ambient temps I guess).

[blazin-asian]

man, my load temps at 3.6 are in the 70s. the highest is 73 on core 0 and 1.

my vcore is around 1.45v. i need to throw some more fans in the case or something

[lowtcell]

So far for me 4GHZ = FAIL. I got up to 3960 last night at 1.5 Bios Vcore, but no go above that. Idle temps at 3960 were in high 40's. Didn't try to load yet, might have another go at it tonight.

Have you tried bios 0402? I use it and with g-skill 1006 2*2gb I was able to use 1:1, 5/6, 5/8 and ¾ with 9*333 and 8*400, 413 and 425, but I tried with 8gb and wasn´t stable for gaming so I returned them and put again my old kingston that with the q6600 and that bios is rock stable with this board instead bad temps readings sometimes and 4/5 don´t work. I use 1:1 because this ram don´t overclock much from 800mhz but got nice results for a 6400 5-5-5-15 with the Go at 8*425 using the 333strap. Here is a picture of everest (trial) that I took with the phone, I don´t know yet how to make and load here a screenshot.

I'll have to look for that bios and give it a try

[Loser777]

Anybody got a better Q6600 G0 then me ?

He does 4Ghz Prime95/Orthos stable on 1.384Vcore, max suicide on that Vcore is 4185Mhz ... Batch is L737B242 with a VID of 1.22500 ....
Wafer number is in the 60-70's ...

I'm just curiuos becuase this thing almost overclocks like a 45nm cpu ... .

Except 45nm CPUs can degrade at that voltage, while yours won't.

[Prodigys]

You hit the spot.
This is why the Q9450 stinks so much, for 45nm cpu's you can do 1.42V max for 24/7 i think, otherwise they degrade fast. Besides that, with the 45nm quads FSB wall of 440-450 in my mind, it can reach only a bare 450 x 8 or 3.6Ghz.

My Q6600 rocks , only 1.384V on 4Ghz and max suicide on that voltage is 4185Mhz, i want to see a Q9450 or Q9550 do that .

Anybody intrested to buy ?

Of course, here are my 50 bucks, do you prefer PayPal or VISA?

Just joking, kick-ass chip you have there.

Mine (unlucky one) in signature (and I don't believe much in degradation stories, as you can easily argue).

There's a huge thread about E8400s degrading @ 1.3v...
What is usually safe for a Q6600 24/7?
1.5v?

[lefy]

1.5v?

that's seems to be the consensus from random posts around this and other forums. i'm no expert, but my 24/7 OC stays under 1.4550v

You mean 1.4v for the E8400 dont you. Here a link to a temp quide for Core duo/Quad etc. which gives all the safe limits http://www.tomshardware.co.uk/forum/...perature-guide - doesnt mean you have to follow them of course - overclocking always carries a risk -pushing the limits is all part of the fun just might cost you though

What upscale intel processor does a q6600 g0 at 3.0 (333x9) benchmark closest too??

[loonym]

None because the 'upscale processors' are all at 3800++

Seriously though, it's comparable to a QX6850 at stock.
