AW M11x R2 Overclocking Bios A04

Hello,

Just purchased the M11x R2 which is my first Alienware. I have a quick question on the overclocking in BIOS A04. If I remember correctly with A03, you could actually choose the clock speed of the CPU, up to 2.66GHz. Now when I upgraded to A04, the options under Overclocking are Disabled and then 130Mhz-166MHz. Did something change, or is my BIOS corrupt? I flashed twice, to no avail.

Thanks,
