My cpu have to do 3.8 with 1,25v, it have done on another board, but i cant do the same here.

I tryed 450fsb with less than 1,3v on vtt, and give me errors on boot.
when i could go in, i tried to raise the vNB to give me stabilty, but i cant.
using mult 6x or 7x for the tests, and vcore enough to it.

PLL i am using between 1,54 and 1,56.

I am almost giving out and willing try to change the board.

What BIOS Revision are you using?? I think your issue is either 1: you have an old BIOS or a bad version 100x - 1403. The 1406 is supposed to resolve issues with running prime exc.. or 2: You are running a CME option your CPU doesn't like.
