    My g4 has two slots for RAM. One is empty, the other has 512MB. I need to increase the amount of RAM prior to upgrading my OS from 10.3.9 to 10.5 (Leopard). One website states I can upgrade to a max of 2MB, while another states I can only upgrade to a max of 1MB. Which is correct? And, does each slot need the same amount (i.e. 512MB in each for a total of 1MB), or can I keep the current 512MB and install 1MB in the second slot.

    That PowerBook takes up to 2GB, so you either buy one or two 1GB PC2700 DDR 333MHz 200 Pin low-profile memory module(s).

    You can have unmatched pairs of RAM sticks, thus keep the 512MB stick and add a 1GB stick to have 1.5GB in total, or you buy two 1GB sticks and have 2GB in total.

    WOW! Talk about a quick response!! Thanks for the info. Is there enough of a difference between the 1MB and the 2MB to warrant the additional expense?

    With Leopard, the more RAM the better, but the actual difference would be 512MB (1.5GB or 2GB), so if you have no problem spending another 50 USD for another 1GB module, do it. Otherwise you can always update later, if the 1.5GB do not suffice.

    Btw, it's GB (GigaByte = 1024 MB), not MB (MegaByte = 1024 KiloByte).

    There will be one or more UK Online Retailers, that offer this RAM though.
