***The Official Q6600 Overclocking Thread ***

My Q6600 was a retail CPU with a VID of 1.2125. I run it at 1.3volts in the bios to get 1.264 idle and down to 1.242 or even lower under full load shown in CPUZ, (has been down to 1.216 briefly), but runs very cool, idle in the low 30's, and under full load around 50c. I use the 120 Thermalright 120A in an Antec 900 gamer case, (lots of fans), and I used the Artic MX2 thermal paste which is supposed to require no curing, but I have gained about 2C in the last few days since I installed it. The E6600 I had prior ran in the low 20's and seldom went over 35C in the same case. I think the giant 200mm fan just above the CPU helps a lot, and I have a 120mm on the heatsink with a 120mm in the rear of the case drawing air straight into the 120mm fitted to the heatsink. These Q6600 are great chips.

That is one hell of a nice chip you have there :D


Mine is prime stable at 3.6, I know it will do 3.8 but temps are warmer than I'd like with my 8800gtx in the same loop.
Will have an update later in the week when I've got my new gear :)
 
I'm still wondering if I should OC more or not, hehe, I just have this thing inside my head saying "no! 3.2 is enough!" but then another thing saying "but you might get 200mhz more!!!"

Here's the current stress test results:

Idle:


Loaded (10mins/600secs):


1minute after stress test end:


What say you guys?

Thought I'd post in this thread rather than make another q6600 thread :P

I have just got a 1.3250VID B G0 Q6600 2.4 and have clocked it in the Bios @:

300 FSB
9x Multi
2.5x SPD Ram multiplier = 750mhz (using ddr800 4-4-4-12 ram and those are the timings)
changed vcore to 1.30v in Bios; reads 1.248v in CPUz and 1.20v Vdrop under load.

I dont wanna go any higher than this (2.7ghz) because I am in a MATX case. I LOAD temp in Prime95-4cores at max 70-68-68-70

I have a question regarding the RAM. Should I use 1:1 Ratio instead of 4:5 or whatever? My ram is currently at 375, but should I set it to the same as FSB? I.e. 2x SPD Multi = 600mhz ram....?

Thanks!
P.s. temps are using legacy PWM 2.2k fan speed when at 70c
G33M-DSR2 MATX Gigabyte Board and for some reason the Ram Ratio SPD Selectors are only 2x 2.5x 3x 4x :<

Regards!
 
In fact I would try the next ratio up since you are only running your memory at 750 which is well under spec.

Alternatively you could leave your memory at 750 are try tightening your timings from the stock of 4-4-4-12.
 
For some reason with my mem/mobo combo (asus p5kc and gskill ddr8000) I get totally random bsods when the memory is clocked 900mhz or above regardless of timings/ram voltage used.

It is perfectly fine below 900mhz though which is a bit bizarre but I have heard the P5KC doesn't like high frequency RAM but I've not noticed a significant drop in performance oing from 1ghz ram to 800mhz in games although of course everest memory benchmarks have gone down a small amount whilst CPU results have gone up (fsb 333)
 
Bought a brand new 2008 G0 Q6600 (which came in a dark blue box), FPO L 806A692 with a VID of 1.325V :( It wasn't a very good clocker and needed 1.45V to get 3.2Ghz OCCT stable.
But I found a second hand G0 with FPO L730B292 and 1.2625V VID (which came in a LIGHT blue box). This one does 3.4GHz at default volts, perfectly stable:)
Needs 1.34V to do 3.6 Gz but maybe able to reduce that by tinkering with VTT and GTL reference voltages.

Cool thanks guys I'll just leave it as it is. At least I know the memory is fine with it being 750mhz (50mhz mower than stock) :P

I cba with the hassle of clocking more in an matx box so i'll just leave it :D
 
An L 809A953 q6600 I have tried is a rubbish overclocker. With a default voltage of 1.325v (in bios) I can get it to 3.0ghz fine, but to get to 3.3ghz requires 1.45v which is ridiculous. A lot worse than a q6600 I tried in the past which did 3.6ghz with 1.35v (in bios).

Mines also a lousy clocker which i bought back in January L 802A680 OEM i managed 3.4ghz stable @ 1.45 in Bios I have not seen many **0 chips about,Luck of the draw i guess:( I wish i had gone for a retail chip not because they clock better .. but due to curcumstances which i have already mentioned I wont be buying OEM again :)

I wouldn't let OEM put you off.


Some of my best clockers have been OEM chips :)
