I'm looking to add more memory to my mid-2011 mac mini (MC815LL/A). I've read a bunch of posts and it seems that it is possible to do so, I also read that I can buy memory rated at DDR3-1866 for it. Unfortunately, I can't find any 16GB DDR-1866 modules (I see DDR3L which I believe to be incompatible). Alternatively, I would be looking to get DDR3-1600 for this upgrade, which I also cannot find. C Can someone recommend 2 x 8GB = 16GB upgrade for my mac mini. Thanks!
