    Hello, today I got my MacBook's RAM upgraded from 2GB to 5GB. (1GB+4GB)

    I was wondering if I should spend the extra $90 to upgrade to 8GB. (4GB+4GB)
    (I heard something about dual-channeling which I didn't fully understand...)

    I mainly use the Macbook for writing university reports and browsing the web.
    Really, the only "processor/graphic intense" applications I run is StarCraft 2.

    Thank you.!

    Depending on your exact MB model, 6 GB or 8 GB might be the maximum.

    Open Activity Monitor and go to the System Memory* tab and look for Page Outs and Swap used and report back.

    If you do not have "Swap used" bigger than 1 GB on a typical day, you should be fine.

    Dual channel support (two RAM modules with the same capacity) gives you a 10 % performance boost, thus it is unlikely noticeable for your stated computational needs.

    Thanks for the fast reply

    My MacBook's maximum is 8GB.

    My Page Out and Swap Used is both 0 bytes.

    So you're saying Dual Channeling wouldn't really affect performance very much?

    Edit: 1.95GB RAM Being used.

    Correct, especially for the uses you list.
