Crucial Technology CT2KIT12864Z335 - 2GB (1GBx2) DDR-333 PC-2700 128Megx72 CL2.5 2.5V Unbuffered 184-pin

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. 184-pin DIMMs are used to provide DDR SDRAM memory for desktop computers. Standard 184-pin DIMMs are available in PC1600 DDR SDRAM PC2100 DDR SDRAM PC2700 DDR SDRAM and PC3200 DDR SDRAM. To use DDR memory your system motherboard must have 184-pin DIMM slots and a DDR-enabled chipset. A DDR SDRAM DIMM will not fit into a standard SDRAM DIMM socket. (Information about which memory technology your system uses is included in the Crucial Memory Advisor tool.) The number of black components on a 184-pin DIMM can vary but it always has 92 pins on the front and 92 pins on the back for a total of 184. 184-pin DIMMs are approximately 5.25 inches long and 1.25 inches high though the heights can vary. While 184-pin DIMMs and 168-pin DIMMs are approximately the same size 184-pin DIMMs have only one notch within the row of pins.
