    Currently have 2gb In my jan 2009 MacBook 2 x 1gb pc2 5300 667mhz. On wiki says I can put 4gb in of pc2 6400 800mhz. Now I thought it had to be the same type or will it work with what it recommends the 800mhz type would appreciate some clarity thanks

    If you put in 800 - chances are the MacBook will not boot up. You need to put the same type of RAM into the machine. So, 667Mhz. You can put 2 x 2GBs in.

    The early 2009 non unibody white Macbook 5.2 will take and use the faster memory. It comes with the 5300 but will take the 6400. I have had 4 gigs of 6400 in mine for the last 3 years and it works well.

    This was well covered in 2009 on this site.

    Go onto the Crucial memory site and enter your macbook specs and it will find the optimal RAM for your machine.
