Fsb probs on my Msi 6337 i815E Pro

Hi guys,
I want set the Fsb on 133Mhz to give more speed to my Cellie 2 900 cD0 now rock stable @1123Mhz (9x124Mhz) at the rated voltage, but when I set the SW1 jumper for 133Mhz the system doesn't boot.
I've tried with all the VCore & Vio possible, with only one mem module, and also with the most conservative mem timings!
Can you help me? Any suggestion appreciated

P.S. for sure not an heat prob, @1123Mhz 40-41 degree C max @full load (for more detail about the system take a look to my signature).

Please, can you help me to understand what's wrong?

Come on guys & gals, plz

Finally it works @1.20Ghz rock stable,
The prob was that my Mobo doesn't wanna Post at boot up @133Mhz, the classic black screen of the death, and now it works! probably this is the present of my Box for my Birthday! I really appreciated
