Hey, I am planning to upgrade my 27" 2.93 GHz i7 iMac first to 12 GB and later to 16 GB. It comes with only 2x2GB Apple memory installed. Now I wonder: Will this (link) OCZ ram work together with the Apple RAM so that I can have 12 GB and not only 8? http://www.ocztechnology.com/produc...z-ddr3-pc3-10666-ddr3-sodimm-4gb-edition.html According to the page its CL 9-9-9-20. Most other chips Ive seen are denoted as CL 9-9-9-24 or just CL9. I have searched through most forum articles about that topic but Im not entirely sure. Clock speeds match though no idea about different CAS latencies. Btw, I could also get 4GB from other vendors: G.Skill 88 GeIL 90 OCZ 90 (price for comparison) Kingston 120 Samsung 110 What should I buy?
