    240-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.

    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.)

    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.

    • Q:

      I have a Dell Dimension 5150 / Pentium D940 with 2*512MB(533MHz) RAM. It is very slow to respond and execute actions especially when using the internet and e-mail. Is the 2GB kit appropriate and should it improve performance? What other type of upgrade would assist performance?

        A:

        A RAM upgrade is the cheapest and most effective way to improve the overall speed and performance of your system. It will not necessarily improve your internet speed and you should check this with the provider.

    • Q:

      I want to upgrade from 1gB to 4gB. Could I use DDR2 PC2-6400 memory instead of DDR2 PC2-5300 in my Dimension 9100? Does the bandwidth make a difference?

        A:

        The Dimension 9100 can only support DDR2 PC2-5300 speed memory so unfortunately PC2-6400 would not work in that system.

        A:

        DDR Pc2 6400 should be backward compatible ,but it is recommended to use the correct bandwidth in accordance with the bus speed on the motherboard.

    • Q:

      Hi, Just to clarify a question / answer that has already been asked - Dell specify the memory for my Dimension 5150 as 533Mhz DDR2 PC2-4200. Will the PC2-5300 Crucial memory work OK? I presume it will simply work at the slower speed. Thanks.

        A:

        It will. Our PC2-5300 is the slowest speed of DDR2 memory that we manufacture. We have a very good sales history for this memory when sold against this system.

        Yes it will work at the slower speed.

        It works ok in my machine. I replaced two 250 MB memory cards with two 1 GB memory cards and the improvment in computer speed is significant

    • Q:

      Your website lists 4GB as the maximum I can install on the above computer, however 2GB kit is recommended.
      Will I get any advantage from installing 4GB versus 2GB?
      (The PC is currently as purchased with just 1GB.
      Thank you for your advice

        A:

        Generally speaking, the more memory you have in your system the better it will perform. It all comes down to what you use the PC for and how happy you are with it's current performance. Bear in mind that if you have a 32-bit version of Windows then installing 4GB will only show as 3.5GB due to the OS limitation.

    • Q:

      Hi, If I buy this additional memory, do I have to remove the existing 1GB card or do I just install this next to it and have 3GB of RAM. Sorry if this is a stupid question,but I'm a bit unsure.:-)

        A:

        According to Dell, this model requires installation in pairs so it is likely that the current 1GB is distributed over 2 slots in 2 x 512MB. This will normally be installed in the first channel. We recommend that the larger modules you intend to purchse be installed in the first channel so just move the original parts to the empty slots and put the new pair in the originally used slots.

        A:

        Yes, you could certainly use the 2GB Kit (2x 1GB) alongside your existing 2x 512MB. Please ensure the 2G Kit (2x 1GB) is installed in the first slots as those are addressed first by the CPU.

        Yes. This is the same basic spec I had for my kids' computer. Installing the 2GB kit significantly speeded it up.

        yes I have exactly same one and added other 2GB to that it did work perfectly and system automatically picked it up but I didn't see any strong improvements in speed.
