You need to double the number to get your speed. Your system is using the memory at 1333 settings (if you looked at in your BIOS you would see that as well). You are good to go.

COLGeek a b } Memory September 30, 2010 1:43:19 AM Minimal at best. Not much gained from OCing memory. CPU and GPU OCing is where you see the most impact.
