Answer to "Can I insert 16Gb RAM into MacBook Pro early 2011?"I have a early 2011 macbook pro 15" 2.0Ghz and I installed 2 8GB Corsair modules and it recognizes and works. But I have not, at all, noticed any improvement in the performance :-( I think If you upgrade to 8GB will do the trick.. In a few machines it just won't use all of it. I don't know, maybe it did and I haven't noticed.
