I have a 3.0E on a MSI Pt880 mobo, running about 40c un-oced average. I have tried to OC, but can't seem to get the voltage to a stable point

anyone have that particular setup or one close to it and have advice? Thanks

Also, I am running 1gb (2x 512) of Corsair Value RAM, and a eVGA 6800 with artic silencer 5

Oh, and a Enermax 120 and 90 to boot
 
You can't stabalize the voltage. Prescott Cores have Dynamic Voltage ranges. They change based on the chips needs to keep the heat down. The Corsair Value Ram isn't the best for OC'ing either.

Don't know about the PT880 though. I've never used any Pentium 4 board without an Intel chipset.
 
but surely there is a certain voltage that should still correspond to the clock of the chip, just like with anything else, or I would theoretically be able to just bump it to 3.7 and it would adjust the voltage? Which, so far, hasn't happened.

Yea the corsair is cheap, but I'm on a pretty small budget, and its worked well so far.

The Zalman 700al-cu does its job well so far too
 
Well the voltage isn't just a matter of clock speed. It's also draw based on CPU load and thermal conditions of the processor at this time. The dynamic voltage was something Intel had to put in there to keep the heat down. For no other reason do they do it. Not that I know of anyway.

So your voltages are perfectly normal by the sound of things.
 
for what it's worth i played with one a few days ago but i didnt have the system for long, a few hours, but it was 2xprime95 stable for that long at 3.53ghz

edit: didn't even touch voltages.. just dropped the ram to 333 and bumped the bus to 235
 
I can OC mine with my P4C800E mobo up to 15% (havent tried higher yet) which I think takes it to 3250 mhz and it ran stable, the fan controller just upped the RPM and the temps stayed 40 idle like they were not OC.
