The 12GB (3 x 4GB)GB 240-Pin DIMMDDR3 PC3-12800 Memory Module from Crucial is a set of three 4GB modules designed to run at 1600MT/s frequency (PC3-12800) with a CAS latency of 11. It is a dual inline memory module that requires 1.35V power. The DDR3 memory module has an improved architecture that allows it to transmit data more quickly. The 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or fully buffered modules).
To use the DDR3 memory, your system motherboard must have 240-pin DIMM slots and a DDR3-enabled chipset. This is because a DDR3 SDRAM DIMM will not fit into a standard DDR2 DIMM socket or DDR DIMM socket.
