    200-pin SODIMM

    A small outline dual inline memory module (SODIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). SODIMMs get their name because they are smaller and thinner than regular DIMMs. The gold pins on the bottom of the SODIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a SODIMM are not connected.

    200-pin SODIMMs are used to provide DDR and DDR2 SDRAM memory for notebook computers. To use DDR or DDR2 memory, your system motherboard must have 200-pin SODIMM slots and a DDR- or DDR2-enabled chipset. A DDR or DDR2 SODIMM will not fit into a standard SDRAM SODIMM socket. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)

    The number of black components on a 200-pin SODIMM can vary, but it always has 100 pins on the front and 100 pins on the back, for a total of 200. 200-pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. Like 144-pin SODIMMs, 200-pin SODIMMs have one small notch within the row of pins; however, the notch on the 200-pin SODIMMs is closer to the left side of the module.

      Hi, I have a Compaq CQ60-300EZ (could not find it on your look up table) I notice many other sites offer the PC2-5300 667MHz 2GB upgrade modules for my laptop. Is the PC2-6400 800MHz compatible with my laptop? I want to upgrade to 4GB RAM and the laptop runs Windows Vista Basic. Thanks

        I have done a search for your model the Compaq CQ60-300EZ and it's not listed anywhere online at all. Can you please confirm the part number and we would be happy to recommend memory for you. You can contact our customer service team at the following link: http://www.crucial.com/uk/contact Alternatively if you run the system scanner on the Crucial.com homepage it will scan your system and advise you exactly what memory you will need.

    • Q:

      hi,

      I have a Toshiba satelitte L300-1BW laptop running windows 7 ultimate edition.

      I am interested in upgrading the memory to the 4gb kit (2 x gb).

      My question is will I have to re-install the operating system and will upgrading the RAM affect the information already on the laptop, or does increasing the RAM have no effect on the operating system.

      many thanks

        A:

        The RAM in your system does not hold any information, all your information is held on your hard drive not the RAM memory. You will not loose any information or any have to re-install Windows after upgrading your RAM.

      Hello,
      I have 3GB RAM installed in my iMac. Is it possible to buy 1 x 2GB stick so it increases to 4GB overall or do I need to buy the 4GB kit?

        Yes, you can just replace the existing 1GB module add a Crucial 2GB part to the one you have.

        You can buy the 1 x 2 gb kit as you must have 1 x1gb and a 1 x 2gb installed. Just swap out the 1gb one

        A:

        The CL (Cas Latency) changes with the design/size/speed of the module and is a less important factor than the amount and speed of RAM when choosing an upgrade. Your model can support up to 4GB in total over the 2 slots – 2GB per slot. Two speeds are supported – 667MHz (PC2-5300) and 800MHz (PC2-6400). The speed the RAM can run at depends on what the memory bus speed is set to in your BIOS. You can check what this is set to, match the speed of the current RAM (check the label or try running the system scanner on our website) or just opt for the faster speed and it will clock down to the slower speed if necessary. Only the 64-bit version of Windows will address and utilize the full 4GB. Otherwise, with a 32-bit version only about 3GB-3.5GB will be seen and used.

        As long as the physical amount installed is showing correctly in the BIOS or system properties in the control panel then it is working fine. Just check which version of Windows you have - only a 64-bit version will see and use the full 4GB otherwise only about 3GB-3.5GB will be used.

      I wish to upgrade my Samsung R60+ with your 4gb kit and do the job myself. Would this be as simple a job for my laptop as your tutorial video would suggest. I have never done any computer upgrade work before and would not like to cause any problems with my laptop.

        A:

        Installing a memory upgrade is fairly straightforward, with some time and patience.
        The basic installation procedure for installing a SODIMM is to place it at a 45 degree angle into the slot while applying pressure. Then apply downward pressure on the module until it locks into the side clips. Furthermore, when you first push the module into the slot at the 45 degree angle, please give the module a firm push and press it down into the side clamps.
        Please note that it is possible to have the module locked into the side clamps without the module being fully seated in the slot. If this happens, just remove it and try again.
        You can check our online SODIMM installation guide here:
        http://www.crucial.com/uk/install/sodimm.aspx
        We will also send a general installation guide along with the memory. If you have any issues while installing the RAM you can contact us on our free phone number 0800 013 0330 and we can talk you through the installation.
