Well, there is a thread about modding this mobo around here somewhere. I think Kyosen was the author.
What i CAN tell you is that this mobo droops - mine droops solid .04 - .06 when under 1.5V or more and overclocked. I had a close look at the resistor to be modified - it's to small for me, dont have the equipment nor the skills to solder on so small parts. Should be pretty easy to pencil it though. If it works I dont know, but I've seen som reports that the mod has stabilized the droop for some. Based on my experience on droopmodding other Asus mobos, I would expect the mod to be helpful in achiveing higher stable clocks.
Personally I don't like thees pencil-mods - they are far to unpreditable for my likes.
Look around - the Kyosen thread should be in the 'Intel' section.
