I own a 2012 Mac Mini with 4gb RAM (2x2). I just got a 2011 Mac Mini used that has 8gb RAM (2x4). Is it possible to swap the 8gb RAM from the 2011 to my 2012? And put the 4gb from the 2012 into the 2011? I'm not familiar with voltage and what all the other numbers mean, so I'm not sure. The 2012 has PC3-12800S-11-11-B2 written on it. The 2011 has PC3-10600S-9-11-FP written on it. Any advice would be appreciated!!
