I just bought an imac 2.8(2 gigs of ram)..i'm planning to buy 2 more gigs. Kingston 2GB 800MHz DDR2 SO-DIMM is this ok for my imac ? And second question is, there were only 2 cd's(leopard) in the box? but it says iLife included in the box..? What brand of ram does imac use? so lets say, it is corsair..what happens if i put kingstone next to it? any problems like pc ?
