oh! so i have 2 total slots! no i just have stock memory, so if i bought a 512 stick i could add that?
Right, more or less...if you have the stock memory, it exists on the motherboard where you do not have access to it. This memory is 512 MB for the last iBook G4s (256 MB for the previous generation).
Your user-accessible RAM slot (under the keyboard and AirPort card...see your manual for instructions) should be empty. That slot can accept up to a 1 GB RAM module. Again, make sure you purchase the proper type of RAM for your machine.
