Hi, I'm considering upgrading my rig from socket 939 :(  to a LGA 775 system and I'm really looking forward to get the Intel's Q6600 for gaming and multitasking along with a kick ass motherboard suck as eVGA's 680i SLI mobo or ASUS's P5E (Intel X38) mobo . I've read many articles and seen a few videos of users overclocking their Q6600 from 2.4GHZ stock speed to well over or at least 3.0GHZ on motherboards suck as the ones I've mentioned before. Does anyone have any first-hand experience with overclocking the Q6600 or any other suggesetions? Thanks for your time.

More about : q6600 overclockable

Mine is at 3.0/1333 at 1.3750 nonload 28 and 45C at full load %100 on 4 core's. i use a asus p5k-v g33 chipset and my cosair xms2 2x2gb ddr2 800 and it runs fine. i can get it to boot-in to windows at 3.6 but i know it takes some what alot teaking so i just put it back at 3/1333 all you need to do to hit 3.0/1333 is leave stock voltage and change the front side bus from 266 to 333 and you are done.

Woah 1.3750 is a bit high for 3ghz, are you running a B3 stepping? You should be able to run it on 1.2750.

Anyway to the OP, yes the Q6600 G0 stepping is very overclockable. Nearly all Q6600 can hit 3.6ghz with the right voltages and cooling. The new quads from Intel that are suppose to come out can hit 4Ghz. On air I think.

The QX9650 can. It has unlocked multiplier. Q9xxx we haven't seen yet.

Considering FSB Walls I think the Q9450 will as well. It'll be close... 471 MHz FSB.

It's all luck of the draw!

I originally had a Q6600 GO stepping. With stock voltage, i could only get to 2.7Ghz. The max I was able to get within comfortable voltage was 2.925Ghz with 1.41v (Real, 1.4685 set in BIOS).

I then switched my the CPU with my buddies Q6600 GO stepping that he had in his HP computer. With it I was able to hit 3.2Ghz on stock voltage, and 3.6Ghz at 1.408v (Real, 1.4625 set in BIOS).

Moral of the story:

There are no guarantees that you will be able to get high overclock.

Damn, you had a dud of a Q6600 there with the first one!
November 22, 2007 11:41:49 PM

If you want to buy a Q6600, go to Fry's tomorrow - it is on sale for $200 with a crappy mobo included.

Yes. I actually named him "Dudley" and keep him as a pet. I take him everyday to the dog park, but he just sits there hiding behind his IHS.
November 23, 2007 2:10:56 AM

i have the old q6600 and run it at 2.6x and idles at 40DegC
it goes 3.2 easily but the temp jumps a lot

for gaming, i'd recommend going for a fast oc'able dual core, you'll get better results

no matter how much quad core support a game has, its never gonna be anywhere near optimal

I built three with:
Q6600
P35-DQ6
Ballistix DDR2 800
Ultra120 extreme HS w/ scythe 120mm fan

Two currently OC to 3G/1333 4:5 divider RAM @ 833
One currently OC to 3G/1333 5:6 divider RAM @ 800 or 4:5 divider RAM @ 833 ( I can't remember)

Two with Vcore @ 1.275V set in BIOS.
One with a higher VID of 1.325 needed 1.325 to be stable under Prime95.

Mid 50s load with Prime95.

no i have a G0. but that is very sable for my pc. i tired all the other vcore settings as well i have a whole paper of what was tired and how long i did the test before errors
November 23, 2007 7:22:53 AM

My Q6600 G0 runs 3.0GHz @ 1.24375V BIOS 10 hours of Prime95 on all cores
(1.20000V CPU-z v1.41 and Speedfan v4.33 Prime95 load).
Maximum temeprature at 22°C ambient are 52°C, 54°C, 49°C, 47°C (by core).

If you use (ASUS) Transaction Booster, (Gigabyte) RAM Performance Enhance at EXTREME or something similar to this the voltage is alot higher.
At STANDARD : Q6600 @ 3.0GHz/333MHz on a 1.23750V voltage.
At TURBO : Q6600 @ 3.0GHz/333MHz on a 1.24375V voltage.
At EXTREME : Q6600 @ 3.0GHz/333MHz on a 1.30V roundoff error after 5 hours and 12 minutes of Prime95 on all cores. I did not test further as the temperatures were too high for my taste.

A correction from above:
A divider of 4:5 at 333MHz FSB does not give you 800MHz RAM.
(4:5) 333/4 = 83.25, 83.25*5 = 416.25, 416.25*2 = 833MHz
(5:6) 333/5 = 66.67, 66.67*5 = 400.00, 400.00*2 = 800MHz
So you need a divider of 5:6 or 2.4 on a Gigabyte board for 333/800.

Alright, two questions after reading this thread.

One: Is the $200 Q6600 only on sale in store?

And the second is in response to bazza's comment. I do a lot of work with SPSS lately. But mostly play video games. What would you guys recommend? The Core 2 Duo 6750 or the Q6600?
November 23, 2007 8:30:24 AM

P35 mobo is the best choice to overclock it. X38 is too much, and not needed for pricey stuff since you are using old procie.
November 23, 2007 10:27:16 AM

Mine is a G0 runs 48hours Prime95 without errors at 9x400 at 1.3625 BIOS (1.34 real under 100%load-1.35idle) on a pen-moded ASUS Commando. With Thermalright Ultra 120 Extreme and 1 SFlex Fan coretemp shows 62,64,63,63 Celsius. Have tried till 441x9 = 3.97GHz at 1.45V Real
Coretemp was 72,72,74,74

I have mine running at 3.6Ghz, with 1.408v real voltage. After running prime torture (Max Heat) for a hour, I get a average of ~65 Celsius. I have the same Heatsink and fan (Fan running at 1200RPM).

I'm lapping both the Heatsink and CPU as we speak to try and get the temps below/at 60 Celsius. I'll post my results.


Just finished lapping and testing. My Thermalright 120 was extremely uneven and unsmooth. My Q6600 was also a bit concave.

After lapping both my temps dropped ~10 celsius under load (10.15 Celsius to be exact). Went from 65 Celcius to 55 Celsius running Prime95 torture test (maxheat/max power)

I think my results were on the extreme side due to my TR120 Extreme being so uneven to begin with.

Here was my review:

On the 18th of October, I ordered a Q6600 and was hoping for a G0, but got the B3.

All I wanted was 3.0Ghz to run 333x9 with my mem 1:1 (PC-5400).

So, I tried the B3 in my new Asus Maximus Formula SE mobo, and I have not been disappointed - 3.27 prime stable, and it booted into bios at 3.74 (but windows crashes - all on stock heatsink). So, I will continue testing, and can't wait to get my H2O setup working to see if I can get the 3.74 stable, or higher.

I know that the default voltage for the B3 is 1.35v, but the board only gave it 1.22v and it was prime and orthos stable at 3.0GHz (again, with intel stock heatsink). But it took 1.35v to get to 3.27 stable.

Summary - B3 made me a happy man!

Addendum: After a little tweaking, I got my B3 to 3.6 (450x8) prime stable with PC-5400 XMS2 at 5,5,5,15 DDR2-900. Superpi was 14.555s.

Q6600 is extremely over-clockable, unfortunately the water cooling needed to unleash its full potential is quite expensive.

High end air is good up to about 3 - 3.4ghz though.

babybudha people who cannot get their Q6600 chips over 3ghz most likely have a duff motherboard, or dont know how to over-clock properly, Intel need to have so much headroom to be able to put their chips up on the market I have yet to see any believable proof of a Q6600 that cannot clock above 3ghz.

Hi guys,
the secret to success is to buy from clubit.com they guarantee a go step at 275$.

The overwhelming majority of Q6600s will get to 3GHz with ease, even B3 steppings. All you need is a good motherboard and decent RAM. I would recommend a P35 based mobo such as the Gigabyte DS3 (R or L) and DDR2-800 memory.

For the overclock I would use an FSB of 400MHz and drop the multiplier on the CPU down to 8x. That would give you 3.2GHz and allow you to run your RAM at its native speed with a 1:1 ratio.

Your right I had two of them at 4:5 833, but I change one of them to 5:6 at 800. I think it's still set that way, I might have moved it back to 833. I fixed the post. Good catch.

As you can see the q6600 is indeed great.

But delta, stay away from the 680I chipset. The Nvidia intel chipsets are not really that great. Their AMD solutions are another story though, they aren't bad at all. But the Nvidia Intel chipsets have heat issues and other problems that stack up. Honestly, A p35 mobo is the best way to go IMO.

Why?...If you plan to pay up the nose for a x38/x48 board, it's your choice. But keep in mind you will not be able to upgrade in the future. To penryn yes, but the performance increase is very small 3-6%. When Nehalem is released at years end 2008. It will require a new socket and chipset due to it's IMC and QuickPath connect interface. So why pay so much for a x38? Performance wise, X38/P35 are pretty much identical. Also, dumping cash into a newly released x48 will be expensive. Better to just save nab something like a Asus P5K or Gigabyte P35-DS3R, save the rest of the money for a mobo/cpu upgrade around Nehalem's mid range quads. After all, a native quad with 2 threads per core?, and a MASSIVE increase in performance compared to core?...Heck, I'm there.

I agree Kamrooz. Just go with a P35 for now and when Nehalem come out get a new mobo(which will havePCIe2.0) and a Nehalem Quad. I imagine that DDR3 will have matured even further by then and have drop in price as it will become more of a standard.

But me I am waiting until 2009 for the 32nm versions of Nehalem as those will be even more efficient and I imagine could OC even further on air. And the IMC will probably boost DDR3's performance as well.

So for now a P5K(or other nice P35 mobo) and Q6600 G0. Then go Nehalem. I just can't wait until we get to see the performance of it.

Prices of DDR3 kill Nehalem for me more than anything.

So does their idea to use 3 seperate sockets. No more buying a nice computer with a budget CPU with the intentions of upgrading later. It's all or nothing. I almost feel like the design is going to limit overclocking.
December 8, 2007 4:57:22 PM

I got my hands on GO stepping :-)

Q6600 W/TEC cooling
3.6GHz @ 1.4v core

So, yes it is that OC'able. Thats a 1.2GHz OC!!!!!!!
