    I was hoping to install 3-1GB PC-133 168-Pin Non-ECC non-Reg SDRAM Memory in a Quicksilver G4. Would this memory work?

    G4 Quicksilver 1.8 GHZ 2TB Sata Raid.

    Thanks
    Scott

    You can try installing them but the hardware won't see them.

    1.5GB is the limit. Adding more is a waste of money since the hardware won't use it all.

    It can only address modules of a maximum of 512 MB density, hence the 1.5 GB limit. Be sure to get low-density 512 MB chips, btw.

    I thought it was a 2 gb limit in QS PMs.

    1.5 is only if you boot in OS9?

    The QS G4s have only three memory slots, unlike the earlier (and later) G4s. They can only address 1.5 GB due to the maximum 512 MB DIMM density.

    Mac OS 9 did indeed have a 1.5 GB memory limit, and a maximum of 999 MB for any given application.
