4gb (2gbx2) Ddrm Sodimm

4GB kit (2GBx2), 200-pin SODIMM, DDR2 PC2-5300 memory module...DDR2-PC5300, CL=5, UNBUFFERED, NON-ECC, DDR2-667, 1.8V, 256Meg x 64. A small outline dual inline memory module (SODIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). SODIMMs get their name because they are smaller and thinner than regular DIMMs. The gold pins on the bottom of the SODIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a SODIMM are not connected. 200-pin SODIMMs are used to provide DDR SDRAM memory for notebook computers. 200-pin SODIMMs are available in PC2100 DDR SDRAM, PC2700 DDR SDRAM, and PC3200 DDR SDRAM. To use DDR memory, your system motherboard must have 200-pin SODIMM slots and a DDR-enabled chipset. A DDR SODIMM will not fit into a standard SDRAM SODIMM socket. The number of black components on a 200-pin SODIMM can vary, but it always has 100 pins on the front and 100 pins on the back, for a total of 200. 200-pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. Like 144-pin SODIMMs, 200-pin SODIMMs have one small notch within the row of pins; however, the notch on the 200-pin SODIMMs is closer to the left side of the module.
