Try increasing your vcore one or two notches.

Also try lowering your ram to the lowest multi to make sure it is not holding you back.

ok i will go back to messing with vcore,
i will try lowering the ram

 

[ScoobyJooby-Jew]

huh, i must have changed the vcore the other night. i could have sworn i left it +.05v. it was on +.025v. its now stable at 3.53. I didnt mess with the ram, its reading appx 1200mhz, stock can go to 1333, and says it can OC to 1600
