Mid-2007 - Macmini2,1
Compatible upgrades for: MB138LL/A, MB139LL/A
Standard RAM: 1 GB
Maximum RAM: 4 GB*
Details: *By default, 1 GB of RAM was installed as two 512 MB modules, no slots free. Apple officially supports 2 GB of RAM, but third-parties have been "unofficially" able to upgrade it to 4 GB of RAM using dual 2 GB memory modules. Please note that some memory in excess of 3 GB cannot be used with 4 GB of RAM installed, so some may prefer to quote an actual maximum of 3 GB of RAM.
RAM Slots: 2
