Disabled "SpeedStep" in BIOS but E8600 still slows down when idle

I disabled SpeedStep in the BIOS and the BIOS comment says the CPU
will be set to the default CPU speed but still, when idle, CPUZ still reports
a drop to 2GHZ with a 6x multiplier. Under load it bounces back up to a 10x
multiplier at 3.33GHZ. I am using Vista Premium SP1.

Either way I set "SpeedStep" in the bios the CPU still slows down at idle.
Anyone else have this problem? I want to peg the CPU at 3.33GHZ to
maximize the responsiveness feel of Vista.

Thanks
Tom

  1. 1. disable C1E support.

    2. CPU ratio setting should not be auto, should be 10.
  2. Yes, I agree with both of the above. But how do I do the
    above? Is there something I do through Vista or after it boots?

    My BIOS only seems to have an option to disable "SpeedStep"
    Either way I set "SpeedStep" does not seem to help. I don't see
    anything else to change under CPU control in my BIOS:

    SpeedStep is Disabled
    Virtualization Technology is Enabled
    Execute Disable Bit is Disabled


    Is there something I am missing?
  3. In Windows, check Control Panel/Power Options. Make sure it is set to "High Performance" and not "Power Saver" or "Balanced."
  4. Tell us what motherboard you have. Make/Model
  5. It's a Dell Studio Slim. E8600 & 2 GB DDR2 800.
