The 4GB (1 x 4GB) 240-Pin UDIMM DDR3L PC3L-12800 Memory Module Kit from Crucial is a 4GB RAM module kit. 240-pin DIMMs are used in DDR3 memory for desktop computers and transmits data more quickly than previous memory modules. A 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. To use DDR3 memory, your system motherboard must have 240-pin DIMM slots and a DDR3-enabled chipset. 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" long and 1.18" high. 240-pin DDR3 DIMMS have only one notch within the row of pins.
This high-density memory module contains 8 chips, each providing 512 MB of RAM.
