As long you are using an x64bit operating system, you are fine. but the motherboard only supports ram speed of 1333Mhz, so getting a pc12800 is not an good idea, as you are missing out on speed.
i rather stick then with a ram card that has a speed of 1333Mhz, same as the motherboard
edit: i meant a ram card that has an speed limit of 1333Mhz, not a pc12800 itself xD, my bad
