Crucial CT51264BD160BJ 4GB, 240-Pin DIMM, DDR3 PC3-12800 Memory Module - 4 GB (1 x 4 GB) - DDR3 SDRAM - 1600 MHz DDR3-1600/PC3-12800 - 1.35 V - Non-ECC - Unbuffered - 240-pin - DIMM

DDR3L 240-pin DIMM Desktop modules that operate at speeds up to 1600 MT/s and have a CL11 latency. It is dual voltage and can operate at 1.35V or 1.5V. It is Unbuffered and is non-ECC. It conforms to the industry standard UDIMM layout of 240 pins and is compatible with computers that take DDR3 UDIMM memory. 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). 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. 4 GB of memory to refine your computer's performance240-pin-pin DDR3-1600/PC3-12800 operates at an effective bus speed with minimal power consumption and as a result, you get optimal computer performance with an improved memory heat dissipationNo matter how heavy and numerous the applications that you are using, 1600 MHz memory speed with Unbuffered signal and CL11 latency will run them smoothly CAS LatencyCL11Form FactorDIMMMemory Size4 GBMemory Speed1600 MHzProduct Name4GB (1 x 4 GB) DDR3 SDRAM Memory ModuleProduct TypeRAM ModuleCompatibilityAsus M5A78L-M LX V2 MotherboardError CheckingNon-ECCMemory Voltage 1.35 VNumber of Pins240-pinMemory StandardDDR3-1600/PC3-12800Device SupportedDesktop PCMemory TechnologyDDR3 SDRAMNumber of Modules1 x 4 GBSignal ProcessingUnbufferedManufacturer Part NumberCT51264BD160BJ
