Problème d'Overclocking

Bonjour à tous,

Bon alors voilà, je dispose d'un E4500, de 2Go de G. Skill PC6400 PK et d'une GA-P35-DS3R. J'ai voulu O/C mon proco mais j'ai un léger problème.

Je suis passé par le BIOS pour O/C. Je regle tout puis je mets 11*230. j'ai enregistré mes modifs puis j'ai lancé Windows et là, à ma grande suprise, mon proco. tourne à la fréquence d'origine (sous CPU-Z, Everest, ...) c'est-à-dire 11*200.
Je repasse voir le BIOS et là je m'apperçois que les fréquences avaient bien été enregistré et que le BIOS était réglé correctement sur 11*230.

Donc je comprends pas pourquoi Windows ne les detectes pas.

J'espere que vous pourrez m'aider parce que je galére ^^

Voici mes réglage du BIOS :
