Last week’s article on installing 6GB of RAM in MacBooks brought quite a few responses and questions, most of which came from readers hoping their older PowerBook might hold more than 2GB of RAM. Unfortunately, that article applied only to the machines specified.

I did realize, though, that I didn’t include the other machines that support more RAM than Apple acknowledges. Many aluminum iMacs will support 6GB or even 8GB of RAM despite Apple’s claims. We now carry 4GB PC6400 SO-DIMMs for use in many iMacs. With one 2GB and one 4GB chip installed, these iMacs will support 6GB total; the newest iMacs will actually support 8GB as two 4GB PC8500 SO-DIMMs, adding to their appeal as high-value professional workstations.

Our sales staff are prepared to answer any questions about RAM capacity in your computer. Give us a ring to see if we can squeeze some more performance out of your machine!
