Let me put it this way, that processor has 1333MHz memory controller, everything over that is considered OC. It should work up to 1600 MHz over which there's actually no point going. You can use that RAM providing it's DDR3 but BIOS would default to 1333MHz and you will have to set up to 1600 manually. If you ever change to an FX processor, 1866 MHz would be about best frequency with potential to OC a bit over 2000 MHz.
