NOTE: It's my first time building a PC and I know nothing about RAM.

So I recently just built my new PC. I use a GIGABYTE GA-Z170X-UD5 TH mobo, with 2x8GB (16GB) 3200MHz Corsair LPX Vengeance RAM. When I'm in the BIOS it shows that my RAM is running at 2133MHz, while my RAM is 3200MHz, is it a limitation from my mobo, or do I have to change anything in the settings?
Thanks. (Sorry if I dropped your IQ with this question)
