184 Pin DIMM - 184Pin DDR DIMM
184-pin DIMMs provide DDR SDRAM memory for desktop computers. Each 184-pin DIMM provides a 64-bit data path, so they are installed alone in 64-bit systems. Dual channel DDR systems use two memory controllers and usually require matching pairs of DDR memory. 184-pin DIMMs are for DDR SDRAM modules found in Pentium III and Pentium 4 and Athlon systems. Standard 184-pin DIMMs are available in PC1600 DDR SDRAM, PC2100 DDR SDRAM, PC2700 DDR SDRAM, and PC3200 DDR SDRAM. 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 and 168-pin DIMMs are approximately the same size, 184-pin DIMMs have only one notch within the row of pins.
