I am looking to get some more memory for my macbook. I have the 2.0 Ghz, 80 gig with 1 gb ram. What kind do I need and where should I get it? I have not made any hardware upgrades to this laptop ever since I've owned it which has been for about a year already. The model identifier that it shows in the system profiler says MacBook2,1. I know that this macbook can only hold 3 gigs of ram and I probably have 2x512mb in there. I would like to max out the ram, so I was wonering if I can have 1x2gb and 1x1gb? the 2gb will go into one slot and the 1gb will go into the other slot. Where should I purchase this and what do you recommend I get? I am looking to spend 100 dollars or under. Thanks.
