If I boot to bt4 r1 with from the harddrive it does not detect my cpu overclock, but when I run it in a virtual machine in windows it detect it.

The boot up says 2793 MHz, the vm says 3810MHz. So far the boot up is only detecting the turbo boost no overclock but the vm detects the overclock without the turbo boost.

Anyone got an idea, I got an i7 920 running at 4GHz.
