    Hey guys,

    Looking to upgrade my ram on this, (If possible)

    http://en.wikipedia.org/wiki/File:Apple_PowerMac_G4_M8493_QuickSilver_front.jpg

    It's the dual 1Ghz model

    more info here, under "Four-slot models"
    http://en.wikipedia.org/wiki/Power_Mac_G4

    Right now it is running leopard 10.5.8 and has 3 512mb sd ram installed.
    It shows as 1.5GB SD ram.

    I read somewhere that OS9 would only recognize up to 1.5GB of ram but OSX could recognize up to 2 GB. Any truth to this? If so what ram should I install and what sizes in the 3 slots?

    Thanks!

    Nope. Logic board is the limit, not OS. You have max RAM already.

    Only early models (with 100mhz system bus) and Mirrored drive doors has 4 ram slots.
