I see it but I don't have a solution.

Maybe some strange limitation within the BIOS of the motherboard?
Ah, you wrote that Win does fine ... so ...

Do you have the correct CPU chosen in your kernel-config?

Maybe someone with a core i7 could help out here better than me ...

google finds me this one pointing at apic:

Here are some powertop results I see when compiling = world:

So it seems like all the CPU Power state is fine internally to th= e CPU but, it's just that it cannot go to the higher speeds for some re= ason.
