    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:

      My Dell Inspiron 531 has in it 4 slots 2 slots with 1GB of memory and the other two with 512MB of memory. I operate Windows Vista Home edition 32 bit. If I purchase the 2GB kit ( 1GB x 2 ) Upgrade will I see any benefit in computer speed. I want to get more memory as Adobe Photoshop (my main reason for the computer) is asking for more memory.

        A:

        If you have a 32bit operating system the maximum memory your system will see and use is between 3-3.5GB of memory. This means that you would have no benefit upgrading your system any further as you currently have 3GB installed.

    • Q:

      At the moment I have 2x512mb memory modules I have ordered 2x 1gb modules (I have 4 slots available) do I install the new ones in place of the 2x512mb and then install these last or leave these two modules in place and put the 2x1gb modules last ? would it matter which way round I fit them ?

        A:

        You processor will address the primary slots in your system first - the slots where the original memory will be, which should be nearest the processor on the motherboard. It is therefore advisable to install the higher density modules (1GB) in these slots and then move your 512MB modules to slots 3 and 4.

        IT DOESN'T MATTER WHICH WAY ROUND AS LONG AS THEY ARE COMPATABLE SPEEDWISE.

    • Q:

      so if this product runs at the faster 800mhz compared to the lesser 667mhz of the same memory does that mean my computer will run faster with the 800mhz memory installed.Also useing the higher 800mhz would it have an adverse impact on the computer,as you have both memory's at the same price but one is faster than the other ?

        A:

        The faster module would only have a positive effect on the system in that it would give better performance. The modules are listed at the same price as they cost the same to manufacture so we do not need to sell it at a higher cost.

        A:

        The PC2-6400 is the faster of the two modules. PC2-5300 runs at 667MHz and the PC2-6400 runs at 800MHz.
