Yeah...I did this on a IC7-MAX3 but ended up removing it. It would raised Vcore while lowering the droop. Even with the lowest setting in the BIOS for Vcore I was not able to set the droop to a small value AND keep Vcore low. The correct answer is probably a set of VR's as this resistor is most likely part of a gain circuit and changing to the change the droop is also adjusting the Vcore gain.
