Got my Q6600 stable at 1.1625 in the BIOS, reporting at 1.008 idle and 1.096v load in CPU-Z on my P5Q PRO

When I say stable it's P95 64-bit stable for an hour, haven't tried longer yet.

Only played around with various vcores for an half-an hour or so before the last prime, so with a bit more effort I could probably go lower for load if I disabled the EPU-6 thing, or prevented it from automatically reducing CPU voltage at idle, and disabled Speedstep (as I was getting crashes at lower vcore at idle (.9 or so) not load), but I suspect that would be rather self-defeating, since it spends most of its time in the base Speedstep/EPU 6 setting anyway.

But the load temps have dropped from 51'C to about 44'C for the hottest core, using the stock hsf in ~16'C ambient inside an antec sonata III with a front and rear 120mm...

Win ;)

EDIT:

Primed for 45 mins at at 1.1625 in the BIOS, reporting at 1.008 idle and 1.096v load in CPU-Z, so I think I'll leave it at this for tonight, and maybe try ratcheting it down another step tomorrow evening.

Is the running below stock voltage thing hit or miss just like overclocking? I can't get my e8400 to boot at anything lower than stock voltage.

Am I missing something?

Not sure, although it makes sense I guess :eek:

I'm off to see how much lower I can go ;)
