I'm going to buy the following RAM: Crucial 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1333 (PC3 10600) Laptop Memory Model CT2KIT51264BC1339 Link: http://www.newegg.ca/Product/Produc...na&AID=10521304&PID=4169666&SID=19mf0ocbsthwp I am going to be installing in addition to the existing 4GB of RAM in my iMac that came pre-installed. I know questions like this have been asked a million times before, but here I go anyway. Badger, bring on the ire. 1. Will the combination of Apple RAM (the 4GB that comes with the iMac) and this Crucial RAM prove problematic? 2. See thread title. Has anyone installed this exact RAM? Does it work for you? If so, has it worked for you for more than two weeks? No problems? Thanks in advance.
