MSI P55-GD65 LGA 1156 Intel P55 and Memory Settings

I recently built a new i5 system and im a little curious as to the memory setting or what exactly I should be looking for as far as timing.

Motherboard - MSI P55-GD65 LGA 1156 Intel P55
CPU - Intel Core i5-750 Lynnfield 2.66GHz LGA 1156
Memory - G.SKILL Trident 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000)

Im currently trying to tweak the system to use it to its near max. Right now the chip is overclocked to 3.15 but im not sure what I should be looking at to know if the memory is running at the full 2000? If I use the program CPU-Z what or how do i know if the memory is running at 2000? What numbers should i be looking at?
