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 5.25 inches long and 1.18 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.
