    Hi everyone,
    I am having trouble getting my Athlon 64 3400+ CPU to actually run at normal
    speed under Vista Ulitmate. I have read to other posts on this topic and so
    far have established that Cool'n Quiet will not work for me because my
    motherboard does not provide the correct APCI information.

    In principle I have no problem with this as I don't really care if Cool'n
    Quiet is disabled. The problem is no matter what Power Settings I use Vista
    only every runs the CPU at 800MHz and not 2200MHz. I have verified this using
    many CPU tools and while running CPU intensive tasks like half life 2 etc...
    Does anyone know how to make Vista run the CPU as the native speed?


    ps. my system is a FS Amilo A1630 laptop, AMD Athlon 64 3400+, Uniwill
    258KA0 motherboard, 1GB RAM.

    Note: I have moved this question to the Vista Hardware and Devices group as I
    realise that is a more approprite location.

    Uninstall The AMD drivers
    Reboot and enter the BIOS...Turn Cool'n Quiet off
    While there check to make sure the CPU setting is correct.
    Save and Exit

    thanks for the quick info. i have a clean install of Vista and have not
    installed the AMD drivers. my machine is a laptop and the bios has no
    settings for cool'n quiet or for changing the CPU settings. there never
    seemed to be a problem with XP x64 so I don't understand why Vista has a
    problem. do you have any other ideas?

    I had the same problem with my Amilo A1630, and unfortunately
    Fujitsu-Siemens aren't being very helpful by not supporting Windows
    Vista. The solution is to upgrade to a BIOS that supports CPU power
    management under Vista, which the latest one from FS doesn't...

    Fortunately you can get an updated BIOS from Uniwell at this link:

    I flashed my BIOS with version 1.05 from that site, and now my A1630
    runs Vista Ultimate at full speed. Also the CPU controls in Power
    Options have magically appeared and my CPU performance score in Vista
    has doubled, which is a nice bonus!

    I hope this helps... I'd be interested to know if it works for you too.
