    So I have one of the new 13in MBPs and was wondering if I could use CoolBook or some other program to undervolt it. I wasn't sure as it is a new model but so little has changed I figured it might be possible.

    Thanks

    Why? That would mean lost functionality or lesser RAM/FSB/CPU speed?

    No, underVOLT not underCLOCK. You get the exact same speed with just less power running to the processor, so it runs cooler and you get a slight bump in battery life. Only thing you risk is becoming unstable if you undervolt it to far and then you would get a kernel panic.

    Yes, I am undervolting with Coolbook.

    Have both the 2261 and 2128mhz frequencies set to 1.0 volts, with the ones below each one voltage step lower.

    I haven't had much time to test and go lower, but I have yet to have any sort of crash/freeze for the past 3 days at these settings. I haven't done a thorough stress test, but I have been extracting and zipping a lot of files, doing lots of ichat video conferences, and watching a few 720p movies.
