As you already know RAM goes like:

DDR3 1033
DDR3 1333
DDR3 1600
DDR3 1800
DDR3 2000

and what not with a few extra's in between. I have DDR3 2000 but have them runnin at DDR3 2150 in BIOS and in windows it is runnin at DDR3 2147.9 which is 1073.9mhz. You just double the MHz to equal the MT/s. So 1073.9MHz = 2147.9 MT/s. Not to mention I have them runnin that at cas 8.
