Hi guys. I have a Q9450 on a P5E3-Premium wifi/ap and i can't oc more than 3.2Ghz.

My rams are OCZ ReaperX 1333Mhz and they run memtest with no errors @ 1800Mhz.
The power supply is also good, corsair HX620.

The problem is when i set fsb's higher than 400 i get errors on prime very quickly.
I tried 450*6 just to test the max fsb and when i run prime i get 2 errors in 2 seconds. I also tried to reduce the ram frequency to ~1300 but it's the same

I increased a little bit vcore, nb, ppl, vtt to try to put it stable but with no success, so the problem seems to be on the board and i don't know why!

I'm running bios 401. If someone can tell me why i can't get more fsb i would appreciate :\
