A quote from the article:
While most DDR4 memory modules and kits should work with AMD AM4 motherboards, the latest list provided by AMD includes a bunch of different memory types from the likes of ADATA, Corsair, G.Skill, GEIL and HyperX with frequency ranging from 2133MHz to 3200MHz.AMD expands Ryzen DDR4 memory compatibility list @ Fudzilla
The latest AGESA v1.0.0.6 update for motherboards, detailed back in May by Robert Hallock, a technical marketing guy for AMD's CPU division, talked a lot about DDR4 stability and was focused on kits running over 2667MHz as well as added 26 new parameters which improve DDR4 memory compatibility on the AM4 platform.
