    I have a 15' Powerbook G4 1.67, currently with 512 of ram....so i'm shopping for an upgrade, but not sure which specific type to go with. In my system profile it says i'm running..

    Type: DDR SDRAM
    Speed: PC2700U-25330

    And these are the types i've been seeing to choose from.

    G4 15-inch 1.67GHz (DDR M9676LL/A) Memory
    G4 15-inch 1.67GHz (DDR M9677LL/A) Memory
    G4 15-inch 1.67GHz Double Layer DDR2 (M9969LL/A) Memory

    so which one of those 3 is right for me? thanks.

    The M99xxLL/A number is the model number you should see on the nameplate of your Powerbook

    If your machine says PC2700, then you should get the RAM listed as DDR PC2700 (333 MHz)

    You do not want the DDR2-533 RAM.
