Hi. I just purchased a Mac mini 2,5 i5 on ebay. I really hope all works fine when it arrives. It comes with 4 GB of RAM pre-installed. However, I really want to upgrade RAM because Lightroom takes a lot of it. I'm still puzzled what kind of RAM fits into the Mini and will work best. Is this the right RAM? What's the difference between both kinds? - SO-DIMM 4 GB DDR3-1333 CL9 - SO-DIMM 4 GB DDR3-1333 CL11 Somewhere I've read that the Mac mini can support 16 GB of RAM. Is this true? Some say yes, some say no. Should I go for 16 GB?
