    I am having a bit of an issue with installing 1gb sticks of memory on a powerbook 1.0ghz 15" FW800 (Ali model).

    It is quite happy with 2 x 256 or 2 x 512 but if I try and install 1gb sticks it freezes within 30 secs of booting.

    I have checked the specs and this model should be able to except 2 x 1gb. I understand there was/is a problem with some models in the way they distribute power and this model falls within that range. I am not certain of the exact details as it was something that was mentioned on the apple support forum.

    Is this a common issue which many people have experienced? Is there any work around or am I stuck with only being able to use 2 x 512mb?

    Apologies for waffling and thanks for any advice.

    Not sure if that is the same issue or not :confused:
