    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 computer is about 4 years old now, about the time computers start to slow down, and be unable to run new games at high-end settings.I noticed, however, that my pc only had 2 GB DDR2 RAM, so I figured, I'd try adding some extra memory to boost performance.After checking my pc to know exactly what memory type I needed, I decided to order 2x1gb on crucial, to try it out. [...] I had it up and running in my pc and already noticed a huge performance increase.I ordered another 2x1gb, to replace the old memory that was installed, and my pc became even faster.Now I can run any new game on ultra high settings and with a solid ammount of frames per second.Thanks crucial! This definitely was alot cheaper than buying a new pc every few years.I'd really recommend getting four of these(or the 800 hz version) for any DDR2 32-bit version computer you want to speed up. You'll definitely notice it!Keep up the good work crucial.

    Works well enough tightened down to 5-6-6, but you might want to consider getting 2x2GB for not much more cash. It's everything you'd expect, nothing you wouldn't. It's ordinary which is not a bad thimg.

            Comments about Crucial 1GB 240-pin DIMM DDR2 PC2-6400:

            Downloaded and ran the Crucial system scanner and proceeded to buy the recommended memory. Unfortunately my computer is so old the recommended memory wasn't supported by the motherboard - bus speed of the memory was to fast.
            On the upside, returning it was a breeze and more importantly FREE OF CHARGE!
            Haven't checked my bank account yet, but I would imagine the refund has been made, as I haven't heard anything to the contrary.
            I would like to add that I have bought from Crucial many times in the past and this is the first time I have encountered any problem.
