    More information

    204-pin SODIMM

    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. 204-pin SODIMMs are currently available in PC3-8500 (DDR3 1066MHz) and PC3-10600 (DDR3 1333MHz) speeds.

    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. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)

    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.

      It's a RAM upgrade that just works. Even more capacity to keep multiple apps and a virtualised Windows OS running happily.

          2 x 8 GB ug to Early 2011 Macbook Pro

          • Noticeably faster

          Best Uses

            I have been very disappointed with the performance of my Macbook Pro. Early 2011 model, started going slow even with only half disk full and cleaning up the obvious things. I decided on the memory u/grade after testing memory use. Apple notes say model only supports 8 GB but others have installed 16GB. I tried both, the 16 is faster, about 3 x. It's almost back to new. Be careful installing though, it's so easy, but be gentle with the Mac screws, they dethread easily.

              Before I only had 4 GB of RAM, it made my life extremely stressful when I was doing my work on Logic Pro. The amount of samples and plugins I used caused the program to crash often. Now with the addition of this 8 GB RAM from Crucial I have 10 GB of RAM and my life has never been better. Thank you, Crucial.

              It works fine

              By Me the photographer

              from Sheffield

              Verified Buyer

              I honestly excepted the speed of my computer to increase significantly after upgrading from 4GB to 10GB of RAM. However, the difference is barely noticeable. Maybe it is just me. It was easy to fit in. The instruction video online was superb. But i am still worried about the speed of my laptop
