I'm thinking of maxing the RAM in my new iMac out to 1 Gig. There is currently a 256 MB chip in each slot. I'm planning on buy from Ramjet.com (unless anyone has a good reason why I shouldn't). My question is this. Obviously, I'll need to take my machine somewhere to have the Apple slot upgraded. I would imagine that the Apple store wouldn't like it if you asked them to install third-party RAM for you. How do Apple Specialists do it? Do I just bring them the RAM I want installed and they do it? Or do have to buy the RAM from them? Has anyone had the RAM in the Apple slot upgraded? Anything to watch out for?
