The 32GB Kit (2 x 16GB) 240-Pin DIMM DDR3 PC3-14900 Memory Module from Crucial is DDR3 memory for desktop computers with an improved architecture that allows quick transmission of data. Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or fully buffered modules).
To use 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.Note:
Crucial Ballistix and Ballistix Tracer high-performance memory do not come in 72-bit or registered modules
