DDR3 240-pin DIMM

240-pin DDR3 DIMM
Approximately 5.25 in. by 1.18 in. (133.35 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 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.

      Comments about Crucial 8GB Kit (4GBx2) 240-pin DIMM DDR3 PC3-10600:

      I put 2 of these kits (4 modules) to upgrade to 16GB in a Dell Optiplex. 1 failed in 3 months, and rather than allow me to return just one module and have it replaced, they want me to return 2. That means taking a computer scientist doing valuable research down to 8gb from 12 until problem solved. Matched pairs they may be - but we all know they could simply allow me to return the one faulty module and replace it with one exactly the same. This is not good enough.

          Comments about Crucial 8GB Kit (4GBx2) 240-pin DIMM DDR3 PC3-10600:

          This kit was used for a Sandybridge board and chip. It's nearly as cheap as the cheapest available, but Crucial extra support makes it a no-brainer. Half the price of last year's triple-channel 6GB kit I purchased, and nearly as fast. This is not a comparatively high performance kit, and I have not tried to overclock it, but dual-channel 1333MHz 9/9/9/24 is plenty for all business and media use, if not gaming.
