    A couple of weeks ago, I inserted a 512MB RAM module into my new iBook. After the installation, the system info. recognized the module as 512 (total of 768). Now (a couple of weeks later) the system only recognizes it as being a 256 module (total of 512). Has anyone had a similar experience or know how to fix it? Thanks a lot for your help.

    Have you reseated the DIMM? If you didn't seat it quite right in the first place it could be possible it's come loose. That's the first thing I'd try.
