CT12864AA1067 - Crucial 1GB DDR2-1066MHz PC2-8500 non-ECC Unbuffered CL7 240-Pin DIMM Memory Module

A dual inline 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. DIMM are used to provide DDR2 SDRAM memory for desktop computers. DDR2 is a leading-edge generation of memory with an improved architecture that allows it to transmit data very fast.
