I need 16G. Don't want the cheapest. I want the most reputable. I would prefer to put the exact same ram in there that is currently in there from apple if that possible. I'm sure ram is ram just like hdmi cable is a hdmi cable but there is still quality differnces I'm sure. So what's the go to company for ram around here? I am finding while editing with imovie the ram gets pretty low. I would rather just forget about it and max it out. one less thing to think about.
