1. First drop your CPU multi to 6x to see if our system an push higher FSB freq..

2. Also lower your RAM freq as you might be hitting your RAM freq wall as you`re running them higher than rated 1600MHz allready..

3. If that doesn`t help also with lower CPU multi and lower RAM freq I suggest more vNB..

If none of those help then you`re hitting your mobo`s FSB wall and there`s nothing you can do about it...

If these suggestions help you go higher on FSB then reboot to BIOS,upp CPU MULTI back to 8.5x and add some Vcore as you`d be running higher CPU freq..

CHEERS..
