I want to add more ram to my old macbook g4 667mhz. I went to fry's electronic and they had the memory, but they said the most it can hold on that computer is 2gigs of memory. 1 gig in each slot, but I read in the curcial website that the max it can hold for that computer is 1gig. Is fry's electronic not telling me the truth. what is the real answer. can I get 2gigs of ram that fry's is selling on sale for 80 dollars for both gigs or what the website states that it can only hold 512 in each slot? please help.
