Asus P7F-M WS - i7-875k CPU Ratio Settings support

Hi,

is there a chance to edit de Bios to support greater CPU Ratio Settings than the defaults? The i7-875k has an free Multiplikator but the Bios highest value is 22 (default turbo ratio).

Bios: AMI
Mainboard: Asus P7F-M WS
CPU: Intel Core i7-875k
Download: http://dlcdnet.asus.com/pub/ASUS/mb/LGA1...S-0705.zip

I tryed AMIBCP 3.46 but i can only change the Value from user to extend user, supervisor and reserved. (Advanced -> CPU Configuration -> CPU Ratio Settings)

Greetings
