Asus Vdroop help

I have a P5B-E and I set my VCORE to 1.3875 on a E6400 @ 3.2ghz

on idle cpu-z says 1.303V and on Orthos Large FFT load it reports 1.248V!!!

from the BIOS that is a .14V drop.. I didn't realize it till now.

Anyway it seems to be stable and my orthos load temps are mid-upper 50C depending on ambient temp.

is this vdroop only a problem if it causes instability? or should i up it a little more to be closer to stock voltage?
 
My theory is that the Intel Conroe CPUs are designed to run at 1.325 volts when at full load so set the bios to whatever it takes to achieve this number in CPUz while running Orthos.

If you're Orthos stable at 3.2 GHz and you have no desire to go any higher then there's no need to raise the CPU voltage any higher. More voltage equals more heat so don't add any more than what you need.

Asus seems to be getting the reputation for largest Vdroop on the 965 boards.
 
thanks for the info.

I don't think i'll go any higher.. i like how it runs right now, it's so damn fast!

my RAM is only rated for 667mhz anyway, i am running it at cas4 @ 800mhz.. i think to go higher i would have to loosen the timings as my board can only do 2.1v vdimm max.
 
Sorry I read that but didn't understand. But basically the voltage is supposed to drop on load?

Yes, that's the Intel specified behavior. However, if your voltages are correct, the vdroop seems to be a lot higher than normal. By comparison, my E6600@3.24GHz goes from 1.35v set at the bios to 1.32v at idle to 1.296v at dual P95 (running on a P5B-deluxe). What do the Asus utilities (Probe, AI suite) report for the voltages?
