Is this 8gb stick compatibel with the 2012 Mini or am I maybe missing something? Elixir M2S8G64CB8HB5N-DI 8GB (1600MHz, CL11, 1x 8GB) DDR3-RAM. If I replace only one of my 2gb sticks, would a later replacement of the second 2gb stick have to have to have the same latency (CL). Does anyone have experiences in this regard? Thank you for the answer?
