I just did the mod and the droop has got a lot less.
Prior to the mod, i saw CPU-Z reporting Vcore going down as low as 1.392V while i had set it to 1.4375V in bios.
This was when running Orthos small fft's.
After i did the mod, i set Vcore to 1.425V (so, a tad lower) and now the lowest CPU-Z reports is 1.408V.
So prior to the mod i needed 1.4375V in bios to get Orthos stable at 3.6GHz due to Vdroop, now i can do the same with 1.425V.
It's just not that the Vcore doesn't fluctuate anymore, it still does but it does not get as low as it used to.
I see there's some misconception about the Vdroop pencil mod, let me explane how to do it:
Locate the resistor in the picture, it's somewhere at the northside of the board.
Take a Digital multimeter and measure resistance of this resistor, mine was 50Kohms.
Just take a soft pencil and stroke the resistor a number of times, now measure again.
Repeat untill it reads 25Kohms.
Make sure there's no graphite particles elsewhere on the board before firing up.
This mod is done at your own risk.
Sit back and enjoy.
