I have a 2011 Mac mini... was the standard i5 model... I upgraded it to 8 GB of RAM right away. But I've recently wanted to upgrade it some more (maybe add an SSD also) to 16GB. I bought the GEIL 16GB 2x8GB PC10660 SO-DIMM kit, and it boots to three beeps. Before I go about getting an RMA and trying with another pair, or another brand... anyone else experience problems upgrading to 16GB? If no, what brand/speed did you have success with?
