       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 DIMMs 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. 
       Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or 
        registered or Fully Buffered modules). (The Ballistix and Ballistix 
        Tracer high-performance memory do not come in 72-bit or registered 
        modules.) 
       To use DDR2 memory, your system motherboard must have 240-pin DIMM 
        slots and a DDR2-enabled chipset. A DDR2 SDRAM DIMM will not fit 
        into a standard SDRAM DIMM socket or a DDR DIMM socket. 
       The number of black components on a 240-pin DIMM can vary, but it 
        always has 120 pins on the front and 120 pins on the back, for a 
        total of 240. 240-pin DIMMs are approximately 5.25 inches long and 
        1.18 inches high, though the heights can vary. While 240-pin DDR2 
        DIMMs, 184-pin DDR DIMMs, and 168-pin DIMMs are approximately the 
        same size, 240-pin DIMMs and 184-pin DIMMs have only one notch 
        within the row of pins. The notch in a 240-pin DDR2 DIMM is closer 
        toward the center of the module.
