    Dell Customer Services in India tell me that the 2.66GHz processor is
    intended only to work at 1.594GHz even though it is used as a desktop
    replacement and is always connected to the line supply.

    Does any member of this excellent NG know how I can make system changes to
    force the CPU to work at 2.66GHz?

  2. Are you using Windows XP? If so check under power management in the
    Control Panel, you could also disable SpeedStep in the BIOS.

    Not really sure if that information is really correct except
    when running under battery. Even then, under Power Management,
    there are options that allow the user to select the type of
    operation when under battery. And AFAIK, it would appear that
    my Inspiron 5100 runs at full speed when connected to line.

    disabling speedstep will ensure that the CPU runs at its slowest compatable

    with the C640 i just gave back, there was a little system driver install
    that was required, and i had to have my system connected to a 90W line
    supply to get fulll power. 70W would degrade the CPU to 750 from 1.8Ghz
