I ordered some new ram for my mac mini mid 2011, Timetec Hynix IC Apple Compatible 16GB Kit (2x8GB) DDR3 1333MHz PC3-10600 SODIMM off of amazon, i don’t know much about ram and didn’t know 1600 MHz is faster. i also found this one on amazon Komputerbay MACMEMORY 16GB Dual Channel Kit 2x 8GB 204pin 1.35v DDR3-1867 SO-DIMM im wondering what if i should return it and buy the other one or what the best ram i should buy
