A friend is upgrading a 2007 Mac Mini with 1GB of RAM.
This model can support up to 4GB or RAM installed, but will only use a maximum of 3GB. So, his options are to install 2 x 1GB, 2 x 2GB, or 1 x 1GB + 1 x 2GB DIMMS.
I see notes saying matched memory is faster. It's hard for me to believe that having 2GB matched would be better that 3GB when running Lion. But does 2 x 2GB count as "matched" in this case? Has anyone ever actually tested?
