Hello all, I was lucky enough to purchase a 21.5 3.3 i3 imac over the weekend The first thing I did was order additional ram from Newegg on Monday. I ordered 2 x4gb sticks of g skill memory (ps its cheaper if you buy the stick separate than together). So now I will have a total of 12 gigs. I have a question on what slots to use now. Should I just add the two 4gb sticks in the empty slots or should I put them in the slots currently taken by the original ram and move the old ones back? I read before that it would run faster using the second way. Is that true? Also, I read that with mac pros, 3 sticks actually run faster than 4 because it will drop to dual channel with 4 sticks as opposed to triple channel with three. Is that the same with the imac. Thanks!
