    I've been hearing much discussion about undervolting the CPU. What is the advantage of this. It sounds to me like that would only decrease performance. Also, I've heard rumblings that this can help correct the high heat problems of "TZS0", which i occasionally get ridiculously high temps for. Is there truth in that? can i hear some specifics on that? i was reading through another thread on it, but it was long and convoluted with no clear answer....

    It does not descrease performance.

    1. Lower temps, (CPU)
    2. Longer batterylife (if you care for that)
    3. Cheaper electricity bill... :D
    4. Increased overall life of the laptop

    GO for it! I decreased my CPU temps with 15-16 celcius. MAX temp for me is 49 atm. instead of 64-5

    Undervolting is great. My x9000 now runs about 3 degrees cooler than the t5750 did in my laptop. Not bad for a CPU that runs at 45w and 1.2gHz faster.

    The only time you will see a preformance hit is if your CPU uses 1/2 multipliers. RMClock doesnt support x.5 multipiers. But at most you are running 100mHz slower than normal (and thats on a rare CPU) Plus if you just HAVE to have the extra 100mHz then you can simply turn off RMClock and once your done turn it back on.

    If you have X9100 rmclock does not use the 11x5 multiplier so i usually just deal with it.

    for the previous generation Penryn processors, there was a work-around for the half multiplier issue. if your processor supports Intel Dynamic Acceleration ( IDA ) then you could enable the IDA multiplier in the profile page of RM clock, then go to the Advanced Cpu Settings page and uncheck the box that says "Engage Intel Dynamic Acceleration" and that will disable IDA but trick RMclock into thinking that a 13x multiplier (IDA) is used when really its just enabling the 12.5x multiplier.
