    184-pin DIMM

    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.

        Yes, any kit of 2 modules on our site is a matched pair. The one you refer to is 2 x 512MB modules.

    • Q:

      I have just purchased the above kit and am unsure of the voltage I should set in my BIOS as some DDR Memory requires 2.6V and some 2.5V.
      I would appreciate your advice on this matter.

        For this module, simply leave your voltage setting to auto, or the default. You should not need to change anything in your BIOS.

    • Q:

      Hi. Are these modules single-sided, and will they support Dual Channel mode?

        These modules come both single and double-sided. Dual-channel refers to computer motherboards that handle memory processing more efficiently by using the bandwidth of two memory modules. Most dual-channel systems will operate without matched memory module pairs installed, but dual-channel systems perform best when memory modules are installed in matched pairs. Check your manual for exact specifications. For further details on dual-channel platforms, please visit our FAQs at
