Have you checked your BIOS.
Check multiplier, base clock and finally thermal status

is it at 2 under load? or 3 under load? look up speed step on wiki to understand more.

which specific p4 3.0 GHz. Depending on the model you may or may not have speed step. if it's P4 631, then it could be speed step. If it is P4 531/530, then it will not have speed step.

Download and Install IPDT(Intel Processor Diagnostic Tool) and post back the results. IPDT result will clearly tell us if it is speed step or if it is thermal throttling or something else.

good luck

The processor frequency could be affected by over-clocking or power management

features. Intel(R) does not support over-clocking of its processors.
Over-clocking is not compatible with the Intel(R) Processor Diagnostic Tool.

In order to ensure the processor frequency is not affected by these, please
enter BIOS and load defaults and disable any 'Over-Clocking' or power
management features that may be affecting processor frequency. Also please set
any software applications which control power management features to default.
