Crucial 8GB DDR3 1866 MT/s RDIMM 240p

Crucial 240-pin DIMMs are used in DDR3 memory for desktop computers DDR3 is the latest generation of memory with an improved architecture that allows it to transmit data more quickly 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 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) Standard DDR3 240-pin DIMMs are currently available in PC3-8500 (DDR3 1066MHz) and PC3-10600 (DDR3 1333MHz) speeds Additional speeds will be added as the technology becomes available To use DDR3 memory your system motherboard must have 240-pin DIMM slots and a DDR3-enabled chipset This is because a DDR3 SDRAM DIMM will not fit into a standard DDR2 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 525 inches long and 118 inches high though the heights can vary While 240-pin DDR3 DIMMS 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...
