Anyone know how to do it? I used the search toolbar and only got 2 hits from it, both didn't seem to have a pencil mod, just solder one.

Id like to know all the voltage mods lol pencil and not
I belive that you can only pencil the Vdroop mod. the rest you have to solder

just pencil the Vdroop smd capacitor instead of using a 50K VR - worked for me

how do u get 2,7? and how to use other vdimms..Originally Posted by over@locker886
i need to have this answered and also if i need the warranty in the future can i just erase the pencil mark?Originally Posted by |SiLA|
how will they know that i have modded my motherboard?
thank you
so instead of the wire, i just pencil the across the two silver parts of the vdroop thingy?

you will need at least a 4B, preferably an 8B as anything less does not drop resistance very much. I tried with a 3B and nothing but with a 6B vdroop(loaded) went from .03V to .02V. better soldering a pot which I wouldve done today if I could find my multimeter!
Is this mod for more mem volt? or?

Slowly finding the balls to be a bit more adventurous and decided to do the Asus P5B Deluxe vdroop pencil mod I used a 2B pencil and about 4 strokes across resistor pictured with yellow line through it below:
------------------------------------------------------------------------------------
Before vdroop pencil mod
- resistance was DMM measured at 80 ohm
- 1.325v bios set vcore = 1.280-1.288v bios monitored, 1.29v idle/1.27v load Asus PC Probe2 reported.
------------------------------------------------------------------------------------
After vdroop pencil mod
- resistance was DMM measured at 37.4 ohm
- 1.325v bios set vcore = 1.296v steady bios monitored, 1.30v idle/1.30v load Asus PC Probe2 reported.
I'm happy with that for now a reduction in vdroop by ~0.03v Asus PC Probe2 reported under load. Not going to be too greedy
------------------------------------------------------------------------------------
Before vdroop pencil mod @1.325v bios set
CPU Prime95 v25.1v small ffts load:
CPU Prime95 v25.1v small ffts post load idle:
------------------------------------------------------------------------------------
After vdroop pencil mod @1.325v bios set
CPU Prime95 v25.1v small ffts load:
CPU Prime95 v25.1v small ffts post load idle:
------------------------------------------------------------------------------------
3600Mhz use to take 1.45v (1.38v Asus PC Probe2 loaded), now with vdroop pencil mod 1.4125v (1.38v Asus PC Probe2 loaded)

wait hold on, pumbertot says 8B, but eva used 2B????? im confuzzled!
btw, i think less strokes = less resistance.
plz, im begging you to correct me if im wrong.
i must be carefull, as i love my p5b deluxe wifi very very dearly

more strokes = lowered resistance
really only diff between pencils is one will require more strokes to reach same lower resistance than the other pencil
At higher vcore above 1.6125v the initial pencil modded of drooping resistor from 80ohm to 37ohm resistance wasn't enough to prevent further vdroop. So whipped out the 2B pencil and dropped resistance down to 14.5 ohm. And now it's all good at least from bios perspective
Final outcome
Improvements after vdroop pencil mod are amazing! Before the mod, 10x 400FSB = 4000Mhz would need 1.7v max vcore set in bios for 1.62v idle and 1.59v load. I could pass single Super Pi 32M but Systool dual 32M Pi would reboot at 50-80% mark - Systool dual 32M Pi is a good indicator of whether a setting is capable of dual Super Pi 32M.. Now with vdroop pencil mod, with vcore set to 1.65v in bios I get 1.616-1.624v idle and 1.624v load and now capable of Systool dual 32M Pi
Idle
Systool dual 32M Pi load

Ok i done the Mod
When under Load it goes from 1.47v to 1.49v. This normal or have i gone a bit iver the top with the pencil.
Bios Voltage is set to 1.45v
Idle
Load
Sweet, thanks eva2k! I think I might do this next weekend!
EDIT: Wheres the best, easiest to access vCore measure point on this board?
EDIT2: Can a pencil vCore mod be done by penciling where hicookie soldered a 50k VR?

not sure if it's okay.. but it happens to me
Swapped in my Q6600 B3 on P5B Deluxe with same vdroop pencil mod at 14.5k ohm.
Before vdroop pencil mod = 3600Mhz at 1.575v bios = 1.4480v load
After vdroop pencil mod = 3600Mhz at 1.45v bios = 1.432v idle and 1.440v load!
Using 1KW OCZ ProXStream psu.
I'm happy for now
