did u set "performance enhance" to standard? That setting gives me instability with overclocks sometimes if I have it on Turbo or Extreme (especially).

Yes, I've always set that to standard. The flashing red warning was enough for me...

Yeah, it is possible you have a relatively poor Q6600. What kind of Vdroop do you see when all cores are loaded with Prime95? At 1.425 BIOS, I see 1.31-1.33v loaded, for example.

(Did you mean 1.325 BIOS, per your signature?)

The bios setting is 1.40V. At idle, "sensors" (the linux utility for reporting on hardware state) reports the cpu at 1.36V, I believe, although that's a bit of a guess (Its labeled "in0"). Under load it drops to 1.31V. A curious thing vdroop. Although having tested this now, idle is now 1.34V, and 1.31V under load. Perhaps I do have a bit of leeway to tweek the core voltage up a bit.

I would guess that RAM voltage, set to 2.0 in BIOS (+0.2V) is being reported as 1.95V. (labeled as "in1")

I'm never quite sure if things are being reported correctly, though...

I forgot to mention that I have a version 2.0 GA-P35-DS3R MB.

Added later: I've just tried 1.425 V and 9X366=3.3 GHz. That locked up under mprime in a few seconds. Too bad. I wonder if the OEM versions of the Q6600 overclock less than the boxed versions. The former perhaps being intended for computer makers who would not overclock, the latter intended for afficionados.
