Crucial 2GB (2X1GB) PC3200 400MHz DDR SDRAM DIMM 184-pin Unbuffered non-ECC Memory Module
This 2GB memory upgrade kit contains two 1GB memory modules designed to enhance your system's performance. It operates at 2.6V and has a 128M x 64 configuration.  
  • PCM Part #: 7056841 
  • Manufacturer Part #: CT2KIT12864Z40B 
  • UPC: 0649528729255 
  • Platform: Universal 

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.

"List Price" is the suggested retail price provided to us by our vendors. We make no representation that a substantial number of these products have been sold or offered for sale at the list price. Actual retail prices in your area may be substantially different, Since we sell products on a national basis, it is not possible to know if our merchandise is sold at list price in any particular location or at any particular time. "You Save" reflects the difference between our price and the vendor provided list price shown on our sites. Since the list price may be different than the actual retail price in your area, you may not actually realize a savings of this amount.
Manufacturers sometimes ask that retailers not display a price if it drops below a certain amount. The "click here to see Lowest Price" message indicates that the price of the item is so low that the manufacturer requested that it not be advertised (that is, displayed). In a brick-and-mortar store, you would probably have to ask a salesperson what the price of the product is. At PCM, by clicking on "click here to see Lowest Price" you are essentially asking to see the price, at which point we show it to you.
