    204-pin SODIMM Memory for Mac

    In short, 204-pin small outline dual inline memory modules (SODIMMs) are the form factor used to provide DDR3 memory modules for notebook computers and other small form factor computing platforms.

    To use DDR3 memory, your system must have both a 204-pin SODIMM slot and a chipset that supports DDR3 memory. A DDR3 SODIMM will not fit into DDR2 or DDR memory sockets.

    SODIMMs are smaller and thinner than regular DIMMs, and the 204-pin SODIMM PCBs are always ~2.6 inches long and are usually around 1.18 inches high (though the heights can vary slightly). They consist of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The number of memory components on a 204-pin SODIMM's printed circuit board (PCB) can vary, but the PCB will always have 102 pins on the front and the back both, for a total of 204 pins. The gold pins on the bottom of the SODIMM provide the connection between the memory module and the memory socket.

    Simple and Easy

    Easy to use the website to determine what memory modules you need. Product arrived quickly and was installed in my iMac in less than a few minutes. Restarted and memory instantly recognised and utilised.

    A painless and easy exercise that will, to a certain extent, future proof my machine.

    This was an 8gb memory upgrade for a new computer, it Works perfectly, I now have a 16gb i7 without paying the price a certain computer manufacturer wants for their memory upgrades. I will be replacing all four slots with crucial 8GB memory in the near future.

    The only drawback was the delivery, which seemed to take a long time. I received my computer (shipping from Ireland) at the same time as the arrival of the Crucial memory.

        It was quite easy to install. The memory was recognised by the mac without any hassle. This was less than half price compared to Apple. Highly recommend it.

        Always bought my memory from Crucial and probably always will do. I find the website helps me find the memory that I am looking for and it is delivered to my door in double quick time.
