Just updated the post, please take a look. Thank you very much.
Notice the (O.C.) besides RAM speeds in the motherboard support page. O.C.=overclocked, meaning you have to enter the BIOS and set the speeds there (usually enbaling the XMP profile), otherwise everything reverts to the JEDEC standard for DDR4 (2133MHz.)
For comparison, all core i DDR3 CPUs were rated for 1600MHz RAM, al AMD FX and APUS for 1866, and some of the latest APUS for 2133. But DDR3 at higher than 1600/1866 speeds was always there and working, in most cases you just needed to set the right speed in BIOS.
