Apoligies for the simplicity of this post, but I'm a first time mobo modder - I have read the thread and various others. I'm just looking for confirmation that I'm going to do the right thing. I've hooked my multimeter up to the Vcore measure mosfet shown at VR-Zone, with ground on one of the mobo mounting holes. That's registering around 50-55mV of droop between Idle(1.475) and Load(1.415-1.420). Do I simply apply pencil to the resistor shown until the voltage at load is closer to my idle voltage? And if so, after I'm done - how do I seal the mod? I've seen sellotape mentioned, but would I just cover all the resistors in the area, or do you have to be just extremely precise with a tiny piece? Thanks in advance everyone.
Can no-one help me?
Yes, you just lower the resistance with a pencil in 5-10k ohm steps. People are getting results all over the place so you just have to do it this way...there's no magic number.
To seal the mod just put a peice of tape over the resistor and verify that you didn't accidently rub any pencil off when putting the tape on by checking vdroop.

can anyone post pics (high res preferably) of their completed vdroop mod using a pot / VR?

Just did the vmod with a St. Patrick's Day pencil I found laying around and voila it works~!
Went over the area several times then blew off the pencil dust.
My mod gave me an overvolt. if I set 1.42xx in the bios it shows 1.45 in the bios and in speedfan it shows 1.46 and shows 1.456 in cpuz.
It does not fluctuate at all.
For some reason my CPU fan's speed went up from 1300-1350ish rpms to over 1400, which I like, but I'm wondering what else I have done with this mod.
Ooooh the mystery...
Haha, still happy with the mod.
SO SIMPLISTIC~!
When performing the VDroop mod you influence the amount of possible current flow. Now, there are some PSUs that actually increase their output voltage, up to a certain point, when there's more load. You seem to have one of these PSUs, because the fan speed most likely increased due to an increased 12V-rail.

Now after a full day and turning my computer on again, my voltage went from 1.46 to 1.44 upon full load.
That's straight from speedfan, not a multimeter.
I have an OCZ GameXStream 700w.
I also figured out my ram wasn't stable at 1066.
Running 1:1 with fsb at 431MHz.
Noone ever claimed that pencil-mods are stable (I hope noone did). At least not if you don't seal them.

This mod works wondersI have a P5N-E SLI that has been giving me issues, and now I have one less to worry about. How I long for the days of my trouble-free 939's and socket A's
My HW is a E6600 cooled by a TTBT and 2x1GB Patriot PDC22G6400LLK running @ 3-3-3-10-1T and everything else auto.

Idle------1.30----------1.318------------------1.30-1.31------------1.327
Load----1.25-----------1.288------------------1.28 (once 1.26)--1.310
Vdroop before: .03 after: .017

Load------1.30------------1.353---------------1.33-1.36----------1.378-1.380
Vdroop before: .04 after: .022
It appears to have increased my actual idle volts by approx .01 across the board (.25 higher than set in bios) and has cut my Vdroop in half
Many thanks to couppi, sbinh, Kobalt, and all other posters
And thumbs down to ASUS for letting such an easy to fix issue pass QC

That was a good joke my friend....

Try to find out what VDroop is and then you'll understand that Asus is not really responsible for this "problem". It's no problem, but a function, introduced mainly to cut costs.

Just did the vdroop mod - idle is not 1.54V and load 1.57V.. (measured with Fluke) Bios is selected to be 1.500V
Think it got a tad too much..
(MBM reports 1.54 100% stable..)
So is the vdroop pencil mod definitely safe to do? No risk of burning out the mobo, cpu or other parts?
