Nice OC...I think your RAM could have been left at 1600.....Set the multi on up to like...Hell with that MOBO, I would say x21...the FSB could be played with a little if your RAM would allow for it say like FSB 205 maybe even 210....RAM would go up to 1640 MHz or 1680MHz ...you have already got the RAM voltage for it.....Just my two cents...BTW you would for sure have to push your voltage up on the CPU of course due to the fact that the CPU clocks are going to be on up there to the 4.3-4.4 range
