    I recently decided to upgrade the ram memory on my 2008 Macbook, so I bought two 2gb modules of ram (which total 4gb, which is the max for my computer). They should be compatible with my mac, but when I install both modules, my mac starts up with a black screen and stays that way. The only solution I found is to use one of the original 512mb modules and one of the new 2gb modules. I haven't got the foggiest clue why the two 2gb modules won't work together. Any help or suggestions?
    I have the 2.1 Ghz White Macbook

    This comment explains it, I guess

    You somehow switched the address and the link title when providing your link, above is a proper hyperlink, and it looks like this:

    Thanks, looks like I need to have a little talk with manufacture and amazon. Oh, and sorry for the hyperlink fail.

    So - what did you get ?

    sounds like PC6400 ram that Amazon describe as PC5300 ?

    there should be a label on the ram modules saying if PC6400 800MHz or PC5300 667MHz?
