Interesting, i updated the bios to version 0708 this morning, with the same settings used previously in the bios, and it now stays at a constant 100% Core Speed with 'High Performance ' enabled in Windows 7.
Only 0708 :O I though we were 13+ by now.. EDIT: Yep 1502 now: http://www.asus.com/Motherboards/Intel_Socket_1155/P8P67_PRO/#download EDIT2: Sorry you're using a different board to the OP
