I have a mild OC, running my G0 Q6600 at 3GHz (333 X 9), CPU-Z reports VCore at 1.232V. Cooling is with a ThermalRight Ultra 120. I have been running this setup now for several weeks, and am wondering what the next logical and reasonable step would be to OC it further? I am new at this, but have so far enjoyed the better performance with this mild OC so far. What clock and voltage would be a logical next step?Thanks, Bruce.

Q6600's aren't that good in OC when compared to the E6600. The E6600 I got to 3,6GHz without any problems. Hoewever...the Q600 I could only bring to 3,1Ghz. Has something to do with the position of the cores or something like that.Anyway..I changed to an E8400 (3GHz) and have it running at 4,1Ghz at the moment. Ideal for FSX :(

Thanks- actually last night, after several weeks of running my "mild" overclock, I had a CTD, and rebooted- only to find that my BIOS is now resetting to auto if I try even this mild overclock of 333 X 9 (3 GHz). I'm not sure if I have "broken" something or not, I can boot up with everything on "auto" but the boardv resets everything to 'auto" again if I try to push it harder. RAM is back at running at 1066. I haven;t had time to check stuff out yet, although I ran several concurrent instances of memtest last night and they all seemd to be still testing this morning. Bruce.

Define a mild OC? A Q6600 @ 2,4ghz running at 3Ghz is only 600Mhz. I'm running a 3ghz @ 4,1Ghz = 1,1Ghz OC. Tat's what I consider "mild" :( Like I said..the Q6600 ain't that great. And if you wanna try if your CPU is stable, run OrthosPrime / SuperPI Mod / Prime95for a couple of hours. If your system keeps running during these stresstests for 8 hours, you can bet you @ss that it's stable.Hoewever...I'd personally won't exepct much from a Q6600. If you're able and really do want more power in FS(9 or X), get a new motherboard, cpu, etc...As for still trying to get even more out of your CPU...I guess that there are enough sites that might be of better help to you than Avsim :)http://www.google.nl/search?hl=us&ei=l...600&spell=1

you should be able to easily get 3.6 out of that combo if you have the right stepping model. IIRC it's the G0 or B0 that clocks the easiest.The best stress test to use on todays cpu's is OCCT, especially for FS. Orthos, SuperPrime, etc are old hat and don't necessarily give the best results, especially relating to memory and cpu interaction.You also might look at upgrading your BIOS assuming you have the correct stepping version of the q6600 AND you still get a reset to auto.

Thanks for the replies.My initial problem was that I could not understand why when it worked fine before, that it wasn't now. However, last night I tried raising vCore on the Q6600 to 3.5 volts (in BIOS), and can now OC easily (as of last night) to 3 GHz. What made me think about raising vCore was that CPU-Z was reporting 2.3 volts for 3.0 volts in BIOS- I assume that this is some form of resistance in the board and connections to the CPU that causes that drop? I still can't explain though why it worked OK before with 3.0 volts in BIOS and not now.Thanks, Bruce.

Errrr. Uhhh. 2.3/3.0 Volts???!!! I'm suprised it's not on fire...

Woops- is now 1.35 volts and works, was 1.30 volts and worked previoulsy until several days ago, when I noted that in CPU-Z voltage was 1.23 volts.Bruce.

IIRC when I clocked my 6600 to 3.6 I was just over 1.4v. Voltage = temp increase so if you're still cool and under 1.5, you should be ok.

Those things are pigs, huh?
