240-pin DIMM

240-pin DIMM for DDR2 memory
Approximately 5.25 in. by 1.18 in. (133.35 mm by 30 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.

240-pin DIMMs are used to provide DDR2 SDRAM memory for desktop computers. DDR2 is a leading-edge generation of memory with an improved architecture that allows it to transmit data very fast.

Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or Fully Buffered modules). (The Ballistix™ and Ballistix Tracer™ high-performance memory do not come in 72-bit or registered modules.)

Standard DDR2 240-pin DIMMs are available in DDR2 PC2-3200 SDRAM, DDR2 PC2-4200 SDRAM, DDR2 PC2-5300 SDRAM, and PC2-6400 SDRAM.

To use DDR2 memory, your system motherboard must have 240-pin DIMM slots and a DDR2-enabled chipset. A DDR2 SDRAM DIMM will not fit into a standard SDRAM DIMM socket or a DDR DIMM socket.

The number of black components on a 240-pin DIMM can vary, but it always has 120 pins on the front and 120 pins on the back, for a total of 240. 240-pin DIMMs are approximately 5.25 inches long and 1.18 inches high, though the heights can vary. While 240-pin DDR2 DIMMs, 184-pin DDR DIMMs, and 168-pin DIMMs are approximately the same size, 240-pin DIMMs and 184-pin DIMMs have only one notch within the row of pins. The notch in a 240-pin DDR2 DIMM is closer toward the center of the module.

Ballistix and Ballistix Tracer 240-pin DIMMs

Our high-performance Ballistix 240-pin DIMMs come in DDR2 PC2-5300 SDRAM, DDR2 PC2-6400 SDRAM, and DDR2 PC2-8000 SDRAM. The Ballistix Tracer illuminated, activity-indicating high-performance 240-pin DIMM comes in SDRAM, DDR2 PC2-6400 SDRAM, and DDR2 PC2-8000 SDRAM

    I bought the kits to build two new systems (one for me, one for my wife). Performance on one kit has been fantastic. The other kit had one bad stick, waiting for RMA to process, but I would definitely purchase this kit again.

      Comments about Crucial 4GB kit (2GBx2) 240-pin DIMM DDR2 PC2-6400:

      Choosing the proper RAM upgrade to increase the performance of my older PC was confusing to me.
      I made use of the Crucial scanning tool for suggested upgrades. I ordered the suggested product, and it worked perfectly.
      Easy to install.
      Doubling my RAM from 4 gb to 8 gb improved my PC performance tremendously.
      No issues so far after 2 weeks of continuous use.
      Shipping was fast, and arrived before the promised date.

          This is a nice product, easy to install and no guess work picking it out. It increased speed but not as much as I thought it would. It seems as my computer may have other issues with too many programs and processes running at the same time.

          My computer was so slow pulling up web pages and anything that dealt with MS Office. I only had 1 gig of memory on my computer. I was very close to getting a new pc. I did some research and thought I'd take a chance on some more ram. Upgraded from 1 gig to 4 gigs and man what a difference it made!!! I should be able to hold on to my XP computer at least another couple of years or until Microsoft quits supporting it. If your computer is slow and you've tried everything like I have, try getting more RAM. It's a cheap upgrade, simple to install and REALLY HELPS!! I am well satisfied for [$]..

              Solved my PC problem immediately as this was a matched set of 2-units unbuffered. NewEgg had sent me some GSkill Memory 2-times and it was bad both times. I've always had good luck with Crucial and have learned my lesson when it comes to memory for PC's.

                In July of this year I purchased a new HP a6838f with the intent of upgrading to the specs that I wanted at a total cost that was $150 less than ordering a Desktop Computer "off the shelf" with the specs that I wanted. The two upgrades that I made were an upgraded DVI capable graphics card and an additional 4 MB of RAM for a total of 8 MB. The upgrade in both cases was quick, painless, and truly plug & play.
