184-pin DIMM

Approximately 5.25 in. by 1.25 in. (133.35 mm by 31.75 mm)

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.

      We would need to know the exact model of Dell system you have before we could guarantee the compatibility. Please confirm your system details and we can confirm if this memory is compatible.

  • Q:

    Can I use this (Part number: CT12864Z40B) in place of part number: CT478526 in my Compaq Presario SR1610NX Desktop PC? They appear to be the same. If not what is the difference between them?

    Thank you

      They are actually the same part the only difference is that CT478526 is a Kit of two memory modules. Both are fully compatible with your system.

      Answered on 9/30/2011 by Crucial Support from Meridian, Idaho


      Using my external brain (Google), I was able to determine that both part numbers refer to sticks of the same configuration. It appears one is a single stick and the other a kit of two identical sticks.

      I love my external brain for its power. I know so much I realize how little I know.

    I have an Apple Power Mac G5 dual 2.7 GHz, model G85386YURU4. Will a pair of these chips work? thanks

      Yes. The Apple Power Mac G5 dual 2.7 GHz can support a maximum of 8GB over the 4 slots (1GB per slot) so you certainly be able to use the above mentioned memory module in your system.
