    I have seen 4GB of RAM from Crucial for a new MDP 13". Now, when I install it, will I have 6GB or 4GB? The mac comes with 2GB but will I have to get rid of them to install the 4GB? or can I keep them and have 6GB?

    I'm sorry if this seems very duh. But I want to know. thank you.

    you have 2 slots

    right now, i bet it has 2 1 gig sticks

    if you get 2 2 gig sticks, you will have 4 gigs total

    now, depending on your mbp model, you could get a 4 gig and 2 gig stick for 6 gigs or even 2 4 gig sticks. however, 4 gig sticks are pretty prciy compared to 2 gig sticks

    That should be a safe bet. Apple usually installs matching numbered pairs. It's usually cheaper that way instead of buying one large RAM stick.

    Hanrattycom if you want to know for sure then go to the apple symbol in your menu (top left corner) and select About This Mac. You then click on the More Info button and then select Memory. That will tell you exactly what type of memory you have and it will tell you the size and how many of them you have.

    Needless to say make sure you buy the right type of RAM. A lot of RAM problems come from people buying the wrong type or not placing it in properly. Other than that RAM is very easy to upgrade.

    Buy one 4Gb stick. Remove one 1Gb stick. Insert one 4Gb stick.

    More badboy bang for your buck. :cool:

    The difference between 5GB and 4GB is usually not a problem.
    4GB sticks costs alot more than 2x 2GB.
    So i'd buy 2x2GB now and get 2x4GB in a year or so, when price has dropped (if you need that much)
