I'd use either 8 or 16, using 12 makes it unbalanced

^what he said is not completely true. read the manual CAREFULLY to make sure you distribute an even amount of RAM to EACH memory channel. Z87 has 2 memory channels and 4 slots.

so, if you want 12GB of RAM, distribute it like this:
Channel A slot 1: 4GB
Channel B slot 1: 4GB
Channel A slot 2: 2GB
Channel B slot 2: 2GB
this will give you a Dual Channel SYMMETRICAL memory configuration.

if you mess up and spread out the memory wrong, you will get a Dual Channel ASYMMETRICAL configuration. it's not a terrible thing, but it is better to have the channels even

^what he said is not completely true. ;) 

Most motherboards are:

CPU

Channel A slot 1 (let's say red)
Channel A slot 2 (let's say black)
Channel B slot 1 (red)
Channel B slot 2 (black)

Each set of color has one Channel A and one Channel B. When they sync together, that's what makes them dual channel. So then, that means 4GB modules should be installed in one color. 2GB modules need to be installed in the other color.

Channel A slot 1 2GB (red)
Channel A slot 2 4GB (black)
Channel B slot 1 2GB (red)
Channel B slot 2 4GB (black)

So if you have a motherboard that does not alternate color, then it's:

Channel A slot 1 2GB (red)
Channel B slot 1 2GB (red)
Channel A slot 2 4GB (black)
Channel B slot 2 4GB (black)

or if they are all the same color, just make sure the initial dual channel slots are populated with the same modules (like A2/B2 - 4GB), and the secondary pair of dual channel slots are populated with the other kit. (A1/B1 - 2GB) Just keep in mind one slot from each channel A/B makes dual channel. ;)
