which bios are you using?
Maybe they have done something to the BIOS or maybe the manual is wrong but I am happy with C1E reducing the multiplier & voltage.

I am using official 11 BIOS.

C1E enhanced halt state — Introduced in the Pentium 4 500J-series processors, the C1E halt state replaces the old C1 halt state used on the Pentium 4 and most other x86 CPUs. The C1 halt state is invoked when the operating system's idle process issues a HLT command. (Windows does this constantly when not under a full load.) Entering halt state, which is a lower-power state, will cut a CPU's power consumption and heat production. Intel's new C1E halt state is also invoked by the HLT command, but it turns down the entire CPU's clock frequency (via multiplier control) and voltage in order to work its mojo. This more robust halt state requires significantly less power than the old C1 implementation.
