    Manufacturers do not make 3 GB RAM sticks. 1 GB, 2 GB, 4 GB, 8 GB.

    MacBooks are like most newer computers - they use "Double Data Rate" memory - so their memory controllers work most efficiently when you have pairs of matched RAM installed. Non-Retina MBPs have two RAM slots, and you can usually have somewhere between 4 GB and 8 GB installed, max.

    I have an older MacBook (non-Pro) from 2009 that I have 5 GB of RAM in. It came with two 1 GB sticks; I pulled one out and put a 4 GB stick in. (Yes, the memory is mismatched, but because I more than doubled the memory, the overall performance still went up.)

    For the Mac, Crucial.com and iFixit.com are excellent resources.

    Which MacBookPro? Newer MacBookPros can't upgrade RAM. Anyway, go to a RAM manufacturer webpage (Micron, Kingston), and use their selector to find out your options.
