CT25672AA667A - Crucial 2GB DDR2-667MHz PC2-5300 ECC Unbuffered CL5 240-Pin DIMM Dual Rank Memory Module

A DIMM (Dual Inline Memory Module) contains a number of memory components (usually black) 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 connector on a printed circuit board greater. The pins on the front and back of a DIMM are not connected together.240-pin DIMMs are used to provide desktop DDR2 SDRAM. DDR2 is a leading-edge generation of memory with an improved architecture that allows a very rapid transfer of data.
