+.1v offset/vdroop

[Kaiju]

I know this is covered in a few areas, but I want a general view on all mobo's that have vdroop.

Am I right in saying that when the offset is applied in the BIOS ( i have a P5N-E here), then your vcore is increased by .1volts (1.4v to 1.5v for example), however on full load vdroop, the vcore can take a significant hit.

For example:

1.35v (+.1v offset) = 1.45v idle, 1.39v load. That's a .6v droop.

I'm running more tests to determine the droop at different voltages with the .1v offset. Would be nice to know what everyone else is droopin?

*noticed slight variance in voltages at idle up to +/- .25v

From the look of things, vdroop isn't necessarily a bad thing, you just need to determine the amount of droop and compensate for the voltage loss with a higher vcore setting in the BIOS.

I was wondering if the offset is simply a voltage increase, or will it affect the vdroop with it either on or off?

A few rough notes I made while testing:

testbed: e4300, p5n-e, ocz 2gb xtc rev2, si-120 cooler, 92mm amber on NB, seasonic s12 600w
voltages were measured with the onboard IT8712F chip using Speedfan 4.32 beta 17
idle temps measured five minutes after startup
load temps measured using Core Temp beta after 10mins using Small FFT
temps were averaged of the two cores, but i waited till both cores were the same
after 3GHz, every 10FSB more needed a 0.75v bump in vcore
at 360FSB, memory wasn't stable at 450(900DDR) (further tests to be done)
at 370FSB, memory was slackened as i have yet to test RAM higher (further tests to be done)
good thing i installed the SI-120 over Intel stock cooler
