BAD NEWS:
Last night with the sttings above started to do some strange things like, everytime i changed a setting in bios pc shuted down back up shuts down back up shuts down , and back up with the OC settings not with the safe ones and then it booted fine....
So i was tired by so many "reboots" that i cleared cmos all night and switched to the f8 bios.
Puted the settings back on and the same thing occured .
Then i used optimized settings and the rebooting was gone then i start outing the settings one by one to find what was causing this reboots , then i concluded that the only setting that was causing this was the cpu ref!
So i must assume that the reboot was cause by some bad relation with cpu and mch ref, so now i have cpu ref @ AUTO and iam increasing the mch ref!
Andre whats the safe max 24/7 for mch ref?
BTW this is my solution to cool the MCH :
