Weird effect of BIOS settings on P4C800deluxe

[Bernd Stoeckl]

Specs: P4C800deluxe P4-3GHZ GeIL Memory Bios1016
If I set the Power Management to disable (which I red was advised to get max
performance) I get the effect that the processor constantly runs in idle
mode up to 20% CPU usage. If then I perform any benchmark with several progs
the results are very poor.
If I switch the power management on, the idle usage goes to zero and
consequently the benchmarks are up to expectations.
Does anybody have an explanation for that?

Thank you!
