I don't seem to understand how the speed is defined. I have G.Skill Rip jaw DDR3 1600 (4x2gb(8gb)), but im assuming that my mobo defaulted it to 1333. My mobo says it can do 1600 (OC) easily in the bios, but I don't seem to understand how to do it, or rather, how I would even tell if I did it correctly.

I had CPU-Z make a text doc, and here is a cut of the memory.

At a default CPU/HT Reference Clock of 200MHz, set Memory Clock Mode to Manual, and change Memclock Value to DDR3-1600.
 
it looks like it has the XMP profile loaded, id just do what redduc900 said
