The 16GB 240-Pin DIMM DDR3 PC3-12800 Memory Module from Crucial is a DDR3 memory module used for desktop computers. It is the current generation of memory with an improved architecture that allows faster data transmission.
A dual in-line memory module (DIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The gold pins on the bottom of the DIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a DIMM are not connected to each other.
Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or fully buffered modules).
Note: Note:*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 a DDR DIMM socket.
ECC modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses
Registered modules delay all information transferred to the module by one clock cycle
