    Hi,

    I got a serious problem with my Macbook in WinXp: It underclockes to 1ghz constantly. Even if I let my Macbook calculate prime numbers, the core freq remains at 1ghz.
    This sucks, because I need that performance. The strangest thing: If I uninstall the bundled drivers, the core freq jumps to 1,83ghz. If I install them again, it again goes down.

    Its my first install of winxp, I installed it from a SP2CD.
    Does anybody of you guys have an idea what to do?

    Cheers,
    Johannes

    I installed notebook hardware control on my macbook to monitor it's temp and cpu speed. It underclocked at what you are getting. But changing the setting to max performance will allow the cpu to work at its max speed. Just a thought.

    Good idea, I was looking for something like that.

    I've tried hard, but I am not able to bring my macbook to 1,83ghz constantly. If I enable Max Performance etc it stays at 1,83 for some time - but it keeps switching from 1 to 1,83 ghz for all the time (and so does the performance).

    any suggestions? anyway thank you, xprohx!

    i also have notebook hardware control and mine also (even at maximum performance settings) goes from 2.0 to 1.0 constantly... It's really annoying.. but if im running anything that requires cpu power it goes to 2.0.. and its damn fast

    just an update...
    mine was locked on 1ghz on the NHC.. BUT, if you check on windows (right click on the "my computer"), it says that its at 2.0ghz.. (i was running multiple applications and batch processing at the time, so i was sure it was suposed to be at 2.0ghz, and on NHC it was at "max performance" settings).
    so, maybe its just a little bug on NHC.
