The vdroop mod, you pencil across the resistor removing or reducing the resistance to very little and you will maintain much more consistent voltage. The p5k introduced voltage damper which works very well.
Pencil mod FTW!!! I've done it on my board, but after reading this article
I wonder if screwing with Vdroop may do more harm than good...
