    Memory slots
    how many memory slots are there in an iBook
    When I bought mine I also bought more memory, so I have it with 384MB but they hand me back a 128MB memory
    Why is that?

    Specs:
    PowerMac G4 Cube 450mhz 832mb
    apple and most laptops only have 2 ram slots, they most likely gave you that ram ccause there were no more slots to fill, so all you can do is sell it or give it away.

    So that means that I didn't got what I intented, most likely 512MB (I really don't remember)

    That also means that the computer had 2 128MB memories, one on each slot instead of only one 256MB, well $200 for 512MB is not ship but probably is worth and I would end up having 778MB in my iBook and 2 128MB in my hands
    If I go to the apple store, will they install them for free? I guess so, they did it when I bought the computer

    Actually, the iBooks have 1 expandable slot. 256MB is built onto the Logic Board (motherboard). You can upgrade with a maximum of a 1GB chip to equal 1.25GB or RAM.

    The older ones have 128mb on the logic board, which is what they must have in order to get 384mb with getting a 128mb stick back.

    Specs:
    MacPro, MBP C2D, iMac G4
    The older ibooks were only expandable to 768 I think...

    Nope, those that had 128MB onboard max out at 640MB, as they won't recognise a 1GB module.
    Only the more recent ones, with 256MB onboard, will fully recognise a 1GB module, and max out at 1.25GB.

    And all iBooks (and 12" PowerBooks, I think) only have one memory slot. The 15" and 17" PowerBook have 2 slots, and no onboard RAM, and they will accept up to 1GB per slot.

    Specs:
    Aluminium Macbook 2.4 Ghz 4GB RAM, SSD 24" Samsung Display, iPhone 4, iPad 2
    Actually I think the older ones DID recognise the 1GB module, it just wasn't "officially supported".

    But To the original poster:

    Maybe try asking to exchange what you bought for a larger RAM stick...

    That might be...as it is quite common at Apple...

    A little off topic, but does anybody know if the MDD G4 can accept more than 2GB? That's the limit Apple gives it, but on the other hand, Apple says it supports and recognises 1GB modules. 4 slots filled with 1GB-modules would be 4GB...It's too expensive for me to try out, and I don't really have the need of so much memory...but would be interesting nevertheless, for the future, maybe...

    From crucial.com

    The maximum memory your Apple iBook (G4 800MHz) can support is 640MB.
    The amount of total memory slots in your Apple iBook (G4 800MHz) is 1 (1 bank of 1).
