Does anyone know if the original iBook G4 can take more than 640MB of RAM. I noticed that the newer ones now take up to 1.25GB of RAM. The RAM is exactly the same type and i'd assume that the mother board is the same too or at least similar. I previously owned an blueberry iBook. The Max. RAM in that computer was rated at 160MB of RAM, however I was able to get 288MB of RAM to work. I have also heard that a 512MB stick of RAM works in it as well.
