Your mobo having 2 slots for ddr2 and 2 slots for ddr3 but can't be used simultaneously so ddr3 better and faster and max that supports is 1333mhz modules of max 2 x 8GB Non-ECC,Un-buffered Memory. Any 8GB modules Un-buffered will work. So the ram must be sticks of 4 or 8gb 1333mhz 10600U. Might work others too but the Un-buffered is the best choice because manufacter recomends so you wont have trouble with them.
