Hello all!
Im glad to announce that i developed a fix for the Vdroop on P5K-SE motherboard. I´m an electrical engineer and i work with electronic design. In the past few days i have analysed the VRM of P5K-SE, and i understood how the PWM controler works and how we can adjust the Vdroop. The image attached shows everything. There is another image attached, where you can see how i did the mod on my motherboard.
With the pencil trick, people are getting just average results (max 50% Vdroop reducement), because the original Rfb resistor is "low" (3,6K). If you want more (like me

) you will need to solder a fixed or a variable resistor.
Thank you all, and enjoy this fix!
Felipe.
