E7400 2.80GHz @ 3.50GHz

Configuration

configuration PC

Objectif

Passer la fréquence du processeur de 2.8 GHz à 3.5 GHz.
Pour cela je commpte, dans le BIOS, augmenter le FSB de 266 MHz à 333 MHz, tout en gardant le même coefficient multiplicateur (333 x 10.5) ainsi que la fréquence RAM à 800 MHz.
Il faudra aussi dans un premier temps désactiver l'EIST et régler le VCore manuellement.
