Question about MacBook RAM Upgrade?

[Wishbong]

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.

Upgrading RAM in MacBooks and MacBook Pros​

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

Using Activity Monitor to show you CPU and RAM usage​

* Mac OS X: Reading system memory usage in Activity Monitor​

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.
