Ballistix 240-pin DIMMs are found in DDR3 memory. DDR3 the next generation of memory boasts an improved architecture allowing very fast data transmission. Ballistix 240-pin DIMMs are available in DDR3 PC3-12800 SDRAM (DDR3-1600).
A Ballistix dual inline memory module (DIMM) consists of a number of memory components attached to a black printed circuit board. Gold pins, found 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.
To use DDR3, your system motherboard must have 240-pin DIMM slots and a chipset that supports DDR3 which is a different technology than that of than its predecessors, DDR2 and DDR. DDR3 incorporates different sockets; they are not interchangeable or backward-compatible. (Information about which memory technology your system uses is included in the Crucial Memory Advisor tool.)
The number of black components on a Ballistix 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. Ballistix 240-pin DIMMs are approximately 5.25 inches long and 1.18 inches high, though the heights can vary. These 240-pin DDR3 DIMMs have only one notch within the row of pins, and each technology has the notch in a slightly different location on the module.
