    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.

    My PC had 2Gb RAM under Windows 7, but 2 spare RAM slots. It worked fine with no problems, even with lots of open apps. However, I wondered whether it might do even better with more RAM. I downloaded the Crucial RAM checking applet and it advised that hardware wise I could go to 8Gb, but with 32 bit W7 only a max of 3.5Gb would be usable.

    Looking at the relatively small difference in price between installing an extra 1 Gb or an extra 2, I decided to opt for 2 making 4Gb total.

    Installation instructions were clear and straightforward requiring no specialist knowledge.

    Up and running with increased RAM in a matter of minutes.

    Slight increase in speed on what was already a fast desktop. (Quad Core AMD)

    However, I do notice that especially when running several heavyweight tasks at once that the overall 'feel' is somehow smoother.

    Task manager used to report RAM usage at around 50%, now it's around 30% so PC has more spare capacity I guess.

    Perhaps 3Gb total would have given pretty much the same benefit, but either way, helpful app advised on memory to order, installation easy and painless and there are definite benefits.

    Performance has been rock solid with the new RAM installed.

        After the infamous upgrade to Windows 10, my PC (with 1GB RAM) virtually ground to a halt in everyday use. But after quadrupling the RAM to 4GB, performance shot up considerably, so that now it's just as fast as it was before the upgrade.

        So don't just whinge about Win 10 - get some more memory!
