Crucial DDR3 4GB DIMM 240-pin 1600 MHz / PC3-12800 CL9 1.35 V unbuffered ECC
Crucial CT51272BD160B Crucial 4GB (1X4GB) DDR3-11600 CL11 EC (CT51272BD160B)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.
240-pin DIMMs are used to provide DDR2 SDRAM memory for desktop computers. DDR2 is a leading-edge generation of memory with an improved architecture that allows it to transmit data very fast.
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 DDR2 240-pin DIMMs are available in DDR2 PC2-3200 SDRAM, DDR2 PC2-4200 SDRAM, DDR2 PC2-5300 SDRAM, and PC2-6400 SDRAM.
To use DDR2 memory, your system motherboard must have 240-pin DIMM slots and a DDR2-enabled chipset. A DDR2 SDRAM DIMM will not fit into a standard SDRAM 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 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. The notch in a 240-pin DDR2 DIMM is closer toward the center of the module.
