    Question PowerMac G4 1.25 GHZ Mirror Door Single CPU - Max RAM
    Hi all,

    I'm new to Mac-Forums.

    Appreciate anyone who can advise - I have a PM G4 1.25 GHZ Mirror Door desktop with 2 GB RAM in 3 memory slots, running Mac OS 10.5.
    I still have 1 unused memory slot which I am wondering whether I could install more RAM (like 1GB more) to improve the performance of the Mac.

    I have checked the Apple Support website at: Power Macintosh: Memory Configurations

    But it only says that under Mac OS X, the computer can recognize up to 2 GB RAM. No mention about being able to install or support more than 2 GB RAM.

    Has anyone installed more than 2 GB RAM in a similar PM G4 desktop and the computer still operates without any problem?

    Thanks for your help,

    Welcome! Your best resource in terms of what your Mac can do is Mactracker Mactracker - get info on any Mac.

    You already have maximum RAM of 2 Gb.

    Dear Hughvane,

    Many thanks for your quick reply! So, I got my G4 maxed out already.

    Mactracker is also good reference for me.
