Probably been asked so many times, but just incase, which Ram did you guys get for the MBP 2012? I have seen conflicting stories about some ram causing crashes etc? The CL number being important? I got ram for my old 2011 MBP and it has the odd wiggle and crash, nothing major though, but would like to avoid issues with the newer laptop. Apple want £160 for 8GB of Ram, when amazon sell 8GB for £40. Any advice?
