I've tried searching this, but couldn't find anything. I have a 12" iBook G4 1.07GHz and I want to upgrade the RAM from the base 256MB. Crucial.com lists RAM for both the G4 1.0GHz and 1.2GHz. Apple.com lists RAM for the G4 1.0Ghz and 1.2GHz. Ummm... I'd rather buy from Crucial ($180 vs $300), but I need to know which type to buy. Any suggestions?
