so eva do you just draw a couple of lines from one end to the other and that's it or?

yup exactly took about 7-9 line/strokes to get to 14.5k ohm but best to measure it using DMM after 3-4 strokes

Alpha the 1KW OCZ ProXStream has very steady rails but not the 5v and 3v might not be reporting correctly as speedfan 4.31 doesn't report +5v and +3.3v rails on P5B Deluxe so not sure how OCCT managed to read them ?

how does one measure ohms

switch the DMM dial to the symbol shown one notch above this photo and black and red probes at each end of resistor. (PC is TURNED OFF when measuring resistance)

same symbol is 2 notches above the setting dialed on this photo below

I did the Vdroop mod tonight. Forgot to take a before screenie but I remember the voltages.

Measured resistance was 51.5-52k Ohms. Does not sound right but thats what the DMM said. Yet to measure it post pencil mod. Voltages were taken in Windows via AI Suite.

BIOS = 1.3375v

Before

Vcore Idle = 1.296v
Vcore Load = 1.28v (sometimes dipping to 1.272)

After

Vcore Idle = 1.304v

Vcore Load = 1.304v

NO DROOP!

I was not able to lift my idle volts much from 1.296 but it eliminated the vdroop entirely at these settings. Will try higher FSB/MHz/Vcore on the weekend. I used a 2B pencil and basically coloured it in, I figured it could'nt hurt right?

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

FARRRK me 0.127Vdroop

, thats disgraceful

It pretty much confirms that the Anus P5B Dlx is NOT Quad Core ready

seems nothing a 2B pencil can't help with

vdroop pencil mod on P5B Deluxe really boosted my Q6600 benching max speeds from 3600mhz to now 3829mhz max screenie at only 1.464v vcore load !
