Also if you need vcore higher than 1.5 you can adjust it in AOD by setting the bios vcore higher than 1.5. Then AOD will typically show 1.4x. Then you can adjust from there and use cpu-z to see the actual vcore. That is what I do anyway.

Thanks for the tips Ben!

Seems like I've reached a point of deminishing returns on the voltage though. Anything over 1.5vcore doesn't seem to offer very much (~3.7).

What's wierd is the other night I had it running Prime for almost an hour at ~3.9 (I was a buzzed ) on a cheapo Biostar board which has the CPU/IMC Vids locked together with an offset for the CPU. The board eventually shut down (with no damage), I'm pretty sure the PWM section overheated. I was sober enough to take a SS and the only real difference I see is that I had the CPU/IMC @ 1.4v.. With a +.125 offset for the CPU..

Does anyone know what a safe vid is for the IMC on PhII?
For that matter does anyone know what AMD's stock vid is for the IMC?
If I leave it on auto in bios it boots around 1.125 which seems kinda low...

stock (optimised defaults) vid set on dfi lp dk 790fxb-m2rs/h for PII 940 is 1E (1.1750) for NB (1.8GHZ) and 1.31v (Auto) for CPU.

Thanks man, sounds like it defaults to about the same on your board. I'll try bringing the IMCv's up a little more (1.375 max) and see if it helps my OC any..

I'm actually a pretty wimpy overclocker. If I get to a point where more V's only offer a few more Hz I quit with the volts...

in one test case when i was bringing the NB volts up to ~1.28v to try to get 2600MHZ, things started acting wierd. occt would only see 3 cores when first launching, and things were unstable (even when i brought the voltage/speed back down). i needed to do a full clear (used killcmos and then reflashed) to get it back. not sure if it was related to me bringing the volts close to 1.3 or it was the attempt at 2.6ghz that messed it up. i may try again in the near future to see if it was the volts or the speed, but just wanted to throw that out there...
