What is a 200-pin or DDR SODIMM?
200-pin SODIMMs are used to provide DDR SDRAM memory for laptop computers. Each 200-pin SODIMM provides a 64-bit data path, so they are installed singly in 64-bit systems. 200-pin SODIMMs are available in PC2100 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. (Information on which memory technology is used by your system is included in the Memory Selector.)
The number of black components on a 200-pin SODIMM may vary, but they always have 100 pins on the front and 100 pins on the back for a total of 200. 200-pin SODIMMs are approximately 2.625" long and 1" high, though the heights may 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 right side of the module.
