    Well, I was stumbling around earlier looking at replacing my cooler with a Xig S1283 and stumbled upon something. It was this thread:

    http://www.ocforums.com/showthread.php?t=558347

    It made me think about my own board because it seemed I've had the same problems. It seems I always have to up my voltage so much more compared to other Q6600 users. I know my chip can do 3.6ghz on air, and I'm dissapointed I have to go to extreme voltages to get it, and have to settle at 3.51ghz for daily. I used to think vdroop was between the BIOS and the actual in windows v, and never knew it could affect an OC. Here's the results of my vdroop test which confirm in fact I have a huge vdroop problem.

    BIOS: 1.5375v
    Idle: 1.472v
    Load: 1.408v

    Now, in my research I can't find a whole lot on the DS3R version of the board, I've found a lot of problems with it but not necessarily any fixes (could be that its 4:30am and I have been looking 3 hours.). I haven't taken a close look to my own board to check for the solder points, but it seems like a good bit is different between the DS3L and the DS3R just from looking at pictures. Does anyone know of a guide for the vdroop on my DS3R, can I use the same one, or am I looking at something much more complicated than I want to fix my vdroop? I don't want to do any soldering, preferrably pencil mods only. Any help is greatly appreciated.

    Well this is incredible. I finally got up the nerve to just go ahead and try penciling the circled area in the pic below and I have gotten some awesome results.

    Before:
    BIOS: 1.5375v
    Idle: 1.472v
    Load: 1.408v

    After:
    BIOS: 1.5375v
    Idle: 1.488v
    Load: 1.456v

    Obviously it's still horrific how horrible it is, but it seems that is the max this little penciling trick can do on this mb. I'm still way happy with the results and hopefully I'll be able to knock down the voltage at this overclock later this evening. Good luck to anyone else that may want to do the same thing. :rockout:

    I vdroop modded my P35 DS3R r1.0 with conductive paint, idle vs load was 0-8mv depending on what vcore I set (E8400). Test putting more graphite !?
    1.38xv BIOS was 1.360v idle and load, could RAISE to 1.368v in Small FFT 8K
