DRAM Module DDR2 SDRAM 8Gbyte 240DIMM

8GB Kit (4GBx2) DDR2 PC2-5300 Fully Buffered ECC 1.8V 512Meg x 72. 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. 240-pin fully buffered DIMMs (FBDIMMs) are used to provide DDR2 SDRAM memory for servers and motherboards that use FBDIMM technology, as opposed to conventional registered DIMM (RDIMM) technology. DDR2 is a leading-edge generation of memory with an improved architecture that allows it to transmit data very fast. FBDIMM technology utilizes an advanced memory buffer that allows modules to be connected in series — meaning that more memory modules can be connected (and thus memory density is increased) and errors at the connection points are reduced. Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or fully buffered modules). DDR2 240-pin fully buffered DIMMs are available in DDR2 PC2-4200 SDRAM and DDR2 PC2-5300 SDRAM.
