I am familiar that websites can choose a generic memory for my laptop. But if you read the question I am looking for the highest performance and all I am aware of is Corsair's 1866 laptop memory and I know a little of kingstons 1866 and 2133 but that's it. And I cannot believe out of all the people on this site no one knows anything about laptop RAM. It seems like I might just be smarter than I thought I was about computers. That or no one comes here.
