Default eVGA 650i Ultra Vdroop Pencil Mod

Two strokes with a 2B pencil on the right hand marking (closest to the CPU) on the attached picture fixed my vdroop problem. The area is between the CPU and RAM slots, about an inch from the edge of the board. Apparantly this works on other 650i Ultra chipsets, but I haven't tested this myself.


Before:
Vcore Set: 1.4V
Vcore Read: 1.368V
Vcore Load: 1.352V

After
Vcore Set: 1.4V
Vcore Read: 1.384V
Vcore Load: 1.384V

In fact, at higher voltages I sometimes find that I'm getting the opposite of vdroop; I feel like I should call it v-viagra! Where the voltage increases slightly under load.

As I understand it, any physical modification will void your warranty.

I can't take full credit for this as it was mostly due to discussion on the eVGA forums and elsewhere.

It will drop it because the graphite on the pencil is conductive, so more electricity is able to run throught that chip thus fixing the droop.
