Hi, I want to upgrade the RAM on my 2012 MBP 13" from 8GB to 16 GB. I have the 2,9GHz i7 version, and I am trying to find the correct RAM modules. Will two of these be 8GB corsar chips be good? (2 x 8GB). "Corsair Vengeance DDR3 1600MHz 8GB CL10, 1x 8GB XMS3 modules, CL10-10-10-27, Core i7/i5/Core 2, 1.5V" And is there any "bewares" from others with experience? Thanks!
