Crucial 2GB 240-Pin UDIMM DDR2 SDRAM DDR2 667MHz (PC2-5300) Desktop Memory Module, CL5, Unbuffered, ECC, 1.8V, 256Megx72

The Crucial 2GB 240-Pin UDIMM DDR2 667MHz (PC2-5300) Memory Module is designed for desktop computers. DDR2 is a leading-edge generation of memory with an improved architecture that allows a very rapid transfer of data. 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 greater connection between the module and a connector on a printed circuit board. The pins on the front and back of a DIMM are not connected together. Its Synchronous Dynamic RAM (SDRAM) delivers superior performance.
