Upgrading Mac mini (Mid 2011) RAM I've got a Mac mini (Mid 2011). It currently has 4 GB of RAM which I want to upgrade to 16 GB. I know that officially with these versions, only 8 GB is supported, but I've read from OWC Announces Industry’s First 16 GB RAM Upgrade For Latest Apple Mac Mini Models that you can actually upgrade to 16 GB.

I've found this memory, Corsair CMSX16GX3M2B1600C9 Vengeance 16GB (2 x 8GB) 1600Mhz DDR3L 9-9-9-24 204pin 1.35V Notebook Memory, which I want to upgrade to. My concern is that it's 1600 MHz and that my Mac mini comes with 1333 MHz memory.

How can I understand what Mac memory requirements are so I can select the proper parts to expand it?
I found this site here.
It appears that your mac can only use the 1333mhz ram sticks, the 2012 models can work with the faster memory.
The site also states that 16gb is not suported but unofficial it will work anyway.

In this answer a similar question is answered, if it works it wil run at 1333mhz since your ram slots can't go any faster.
But since macs are really picky about the memory you use there is a big chance it won't work at all.
