Crucial 2GB DDR3 PC3-12800 Unbuffered NON-ECC 15V 256 Meg x 64 DDR3 240-pin DIMM Approx. 525 in by 118 in (13335 mm by 30 mm) Crucial 240-pin DIMMs are used in DDR3 memory for desktop computers DDR3 is the latest generation of memory with an enhanced 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 & a socket on a larger printed circuit board The pins on the front & 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™ & 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 1066 M Hz) & PC3-10600 (DDR3 1333 M Hz) speeds Additional speeds will be added as the technology becomes available To use DDR3 memory your system motherboard must have 240-pin DIMM slots & 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 & 120 pins on the back for a total of 240 240-pin DIMMs are Approx. 525 inches long & 118 inches high though the heights can vary While 240-pin DDR3 DIMMS 240-pin DDR2 DIMMs 184-pin DDR DIMMs & 168-pin DIMMs are Approx. the same size 240-pin DIMMs & 184-pin DIMMs have only one notch within the row of pins Specifications ECC NON-ECC Form Factor UDIMM Module Size 2GB Kit Qty 1 Speed 1600 MTS Tracer False Voltage 15V DIMM Type Unbuffered Bullet Features Increases system performance Warranty Limited Lifetime Specs DDR3 PC3-12800 • CL11 • Unbuffered • NON-ECC • DDR3-1600 • 15V • 256 Meg x 64
