    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. 200-pin SODIMMs are available in PC2700 DDR SDRAM, PC3200 DDR SDRAM, DDR2 PC2-6400 SDRAM, DDR2 PC2-5300 SDRAM, DDR2 PC2-4200 SDRAM and DDR2 PC2-3200 SDRAM. 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.

      I found an item similar on another site which listed the memory speed as 333MHz but couldn't find it listed for this item?

        A:

        Your model can be upgraded by installing a 1GB 200-pin DDR module in the user accessible slot. Both speeds of PC3200 (400MHz) and PC2700 (333MHz) are supported. The speed the memory can run at depends on your system memory bus speed in the BIOS. If in doubt what this is set to then you can opt for the faster of the 2 speeds and it will clock down if necessary to the system limitation.

    • Q:

      I was wondering. I saw a review stating that this ram(3200) would not work with a system that currently had a 2700 ram chip. I also read that the lower the cl was the better. My system currently has the 2700 and since the 2700 chip offered for my computer is a cl=2.5 would it be a better match than the 3200 cl=3. Thanks

        A:

        Crucial memory is designed to be backward-compatible, so generally speaking, you can safely add faster memory to your computer. However, your system will operate at the slower speed. The performance difference between CL or CAS latency ratings is virtually undetectable.
