Cool 'n' Quiet or stuck at 800Mhz

    There are several threads here about AMD machines stuck at the lowest or
    highest frequency, not powering up or down on demand.

    I have the 2nd issue, always at full 2200 Mhz, never throttling down to 1000
    as happens under Windows XP.

    Others have machines always running at 1/2 speed, always at 800 Mhz.

    I haven't solved it, but I did find something interesting at <a
    href="">Silent PC

    They have an article on using AMD Turions for desktops (compared to Athlons)
    and they remarked on, "...the default power state of the processors: The
    Turion defaults to the lowest clock frequency and voltage, and with
    PowerNow!, the clock jumps up when needed. The Athlon 64 defaults to the
    highest clock frequency with Cool'n'Quiet dropping down the speed and voltage
    when the processor is idling."

    Again, I haven't solved the problem, but maybe it's a clue
