I'm sorry guys but I'm getting myself totally confused with the whole RAM thing...I'm looking to get the new lat2 2012 iMAC (27") and want to get my own RAM for it. Can anyone tell me if the below RAM is compatible with the new iMAC? http://www.newegg.ca/Product/Product.aspx?Item=N82E16820148614 I know it says it is laptop memory.....does that make in non-compatible? I read a bunch of the posts talking about RAM upgrades and cannot decipher what is compatible or not. One further question...If I get the standard 8 gig that comes with it, do I need to remove it or can I simply add the new RAM to the empty slots (ie can I use different brands and sizes of RAM)? Thanks in advance!
