    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.

    • Q:

      Hp says the SR1000V uses PC2100. Will a 512 PC 3200 work next to the pre-existing 512 PC2100 module?

    • Q:

      Is this memory double sided? Single sided, high density modules will not work with most systems.

        Stock are always changing so I am unable to guarantee the density of the modules. I would advise you cotnact us over the phone before placing an order. We will then be able to confirm the density of the memory module. You can us by using any of the listed contact methods:

    • Q:

      The computer currently has 128mb of memory. Can I add 512mb in another slot or does the memory have to be the same size in each slot?

        The Dimension 2400 does not require memory to be installed in matched pairs. You should be able to simply add your upgrade to the open memory slot.

    • Q:

      When I add a 512 MB card to my Dell, does the total MB of memory equate to the upgrade and the current memory; i.e. 256 MB + 512 MB for a total of 768 MB of memory? Or is the upgrade a one for one replacement of my current memory, and after install, my PC will now only have 512 MB of memory?

        When you install memory it adds to what is already installed. If you add a 512Mb to a currently installed 256Mb module, then you will have 768Mb total.
