I managed to get a secondhand Q6600 G0 stepping for under 80 quid so I have decided to retire my old E4500(2.95ghz).
What voltages have you guys and girls used when overclocking your Q6600? I am only looking to get mine to 3ghz. I am currently using 1.312/1.328v (according to CPU-Z) for the Q6600 to get to 3ghz. Is this too high??
It has passed 7 iterations of IntelBurnTest and a hour of OCCT so far.
Just mucked around with the settings some more. I got the voltage down to 1.280v/1.296v according to CPU-Z under load . It passed 20 iterations of Intel Burn Test and another hour of OCCT.
According to Core Temp the VID is 1.325v. However it seems that the CPU-Z reading is lower. Does this mean that the processor is actually running at lower core voltage than stock even though it is overclocked!!??:confused:
This may be helpful, in the guide clunk is using a Q6600 G0.

By the way, where did you get a Q6600 for £80? Just wondering as I'm considering going quad core.
I got it on Ebay. You need to keep a constant check but it is possible to get a Q6600 or Q8200 for £100 and under still. It took me a while to get one at that price. The best thing would be to ask a seller what price they are looking for. Some sellers may add a buy it now or end the auction early for a specific price.
The reason why it might show lower in CPUZ is because you have intel speedstep on, so its probably taking the clock speed and voltage down. Coretemp usually shows the fixed vid for the cpu. You should be able to hit 3ghx at stock volts, i run mine around 1.22/23v and it seems fine, but then again I never ran any stability testing software.
I looked at the voltage reading in CPU-Z under load. I was running either Intel Burn Test or Orthos and the CPU cores were all at 100% utilisation.
At 3GHZ, you shouldnt have to touch the voltages.Quote:

Unfortunatly my 3Ghz Q6600 voltages are a tad high but if I try to set them lower I get BSOD or drop a core with prime!
My core temp are good though.
3ghz on a high vid like that seems to be a good overclock, ecspecially if its one of the most recent batches
a low vid like mine 1.250 will do higher clocks simply due to it requiring lower voltage to run at. decent second hand q6600 sell for like £100 give or take a tenner.
Why not crank the vcore up to 1.4 ive managed to get a 400mhz fsb stable at that

I tried decreasing the voltages but under Intel Burn Test the system will BSOD after 15+ iterations.
With the current settings it is stable with 25 iterations of Intel Burn Test,1 hour of OCCT blend,3 iterations of 3DMark06 and 9 iterations of a Crysis benchmark. I will also try Orthos for 12 hours to see if it is stable when I have the time.
I am using a 975X motherboard in my Shuttle SD37P2. The BIOS has limited voltage options as you increase the voltage by 25mV increments but you cannot decrease more it than the rated value for the processor.
defo motherboard limitation there, i wouldnt down the voltage at those settings sounds like you need to take vdroop into account
Is the vdroop very high then for my motherboard?? So if I drop the voltage any further the CPU under load will have too little voltage to function and hence the BSOD after a while??
no your vdroop seems quite normal, should get better the higher the voltage goes.
yes vdroop is causing the voltage under load to drop below what is needed for the cpu to be stable :)
I have uber bad vdroop and vdrop with my 680i even after the mods
I got my (2-3 year old) B3 Q6600 to 3.2ghz at a voltage of 1.45625, sits under load at 57c, so im chuffed with that! FSB of 355. First time o/c'r, so was happy with that.
edit; looking around 1.45v seems very high, couldnt get it stable at anything less though. At the end of the day though, a year later no problems.
Typical B3steeping there, heat i reckon is your problemQuote:

Mine is a GO see my system for volts and clock. the heat issue is a lot less prominent on these SLACR GO steppings
I have a G0 stepping Q6600. I am using it in a Shuttle SFF pc so I do not want to overclock it too much due to heat. At 100% load with OCCT the cores are at around 70C. I may try some better thermal compound as I am currently using Zalman thermal paste(the one with the brush).
you'd be safe letting them go all the way up to 80, even 90 if you feel comfortable, before i stepped into water cooling the max i went is 95, but you will never get real time temps like you do with stress testing.
GO, should still be a good clocker despite high vid, it is most certainly your mobo holding you back buddy
I suspected that my motherboard was the issue. I do already have a backup PC with a better P35 based motherboard and an HX520w psu. I currently have an E4300(3ghz) in that machine. It was easier to overclock the E4300 with the P35 motherboard than the 975X in the Shuttle!! :( I thought of perhaps using the backup PC instead for the q6600 but I only have XP on that machine. The SFF has both Vista and XP. Since Farcry 2 runs better under Vista and both this and Alan Wake(which is supposed to be a Vista exclusive) are supposed to make good use of quad cores I decided to use the processor in the SFF.Quote:

The P35 is what the Q6600 is gagging for! Isnt there any way to get your vista license renewed fro the motherboard change, just like xp, i mean microsoft have to understand that people change hardware all the time!
Give em a ring, theyl more than likely oblige
One of the many reasons i haven't switched to vista
I got mine from MSDNAA(basially for free) so I do not know whether I can transfer it or not?! Anyway I am going to try out the Windows 7 Beta on the backup machine. I got the license key but the blasted direct links for the download gave a corrupted file. Tried a few times on different computers but it did the same thing!!:censored: Hopefully MS will get around to solving this!!
Good luck with it, oh and please tell me what windows seven is like gaming wise if you manage to get it sorted
i was overclocking my second hand G0 Q6600 today and i managed to get to 3.15 without touching any voltages. Im currently on 3.4Ghz at 1.37 Vcore (bios) hitting 67c max. My northbridge is at 1.33 and i bumped up the termination a notch. Only thing holding me back atm is that my northbridge is hitting 73c (well i think Aux my NB... bloody speedfan gives random names to stuff) when under orthos mix stress. Should i be worried about this or it is quite normal?
Under stress testing the this is normal but under everday use, even under what you may consider intensive work your temps will never reach the height of under stress testing, so nothing to worry about.Quote:

And there is the reason.Quote:

I had an AW9D-MAX (975X aswell), and although the board was FANTASTIC, it didnt like the Q6600 at all.
Even though the bios revision allowed me to use it, it simply didnt read all the settings correctly and ran the processor extremely hot.
Sounds like you are doing OK though :)
