I just bought a new RevB iMac G5 about a month ago now and put two Crucial 1GB sticks in there. So I have a 512 stick left over. A friend of mine has a 17" RevA iMac G5 that he bought from Apple in late November last year, but he hasn't added any RAM to it. Can I give/sell him the 512 stick that I'm not using to put in his computer?
