I have a 1.33 ibook and just installed what was suppose to be a 1 gig RAM chip. My computer tells me I have 768 megs of RAM now. I took the chip out and looked and it is labelled as a 1 gig chip so it isn't a matter of being shipped the wrong chip. My question is this: Did I get shafted and the manufacturer mislabeled the chip or is it possible that for some reason my computer can't/won't recognize a 1 gig chip? Any answers or suggestions on what I should do would be greatly appreciated.
