I just picked up a brand new 1.33ghz 12" iBook G4. In the latest update, Apple has moved the airport networking to the main logic board, leaving the space above the ram free where the airport card used to rest. What I noticed today, is that the standoff that holds the ram is taller, and now appears to have two slots (though only the top slot has mounting clips for ram)!

All of Apple's documentation claims the iBook has only one free expansion slot, but it sure looks like there's another one there. I don't have another stick of ram to try (and I'm a little nervous about breaking something), but has anyone else tried putting another stick of ram in the second slot?

Sounds weird. Are you sure about this? Could you post a picture?

I have the same model iBook, and I could be wrong - but I believe that the original RAM chip is soldered onto the motherboard. Beyond that, there's only 1 expansion slot available to upgrade the iBook's RAM. I must admit though, I was quite confused when I installed my extra 512mb of RAM since the diagrams on Apple's website didn't match exactly what I was seeing when I examined and opened up my iBook. Considering the fact that this is my first laptop from Apple, I'm still surprised I installed the RAM correctly.

There's only one slot with mounting clips, but just below that, and just above the soldered-on ram, is what appears to be another slot. I'll post a pic when I get home tonight...

Wow, weird. I should open this thing up and see if it's for real. But if that's the case it really wouldn't matter because the Book can supposedly only take 1.5GB.

But that number is based on the number of available slots and the size of the largest RAM chips available right now. If there are more usable slots, then 1.5GB is not the maximum.

bsimons,

There's only one available slot. The other "slot" you are seeing is just a piece of plastic from the soldered-on RAM. Trust me.

OogaBooga: The "other slot" is part of the same structure as the marked slot, not some other piece. You can see it best in the third picture at full resolution. That slot has all the same wires as the "normal" slot above. Perhaps you mean those wires are just connected to the soldered on ram?

For what its worth, my iBook G4 800 had a much shorter ram structure without the fantom slot.
