Be careful with these "for amd" or "for intel" ram sticks. I bought 2x 8gb ddr3 "for amd" stick from banggood(were cheaper than "for all" ram), naively thinking ram is ram and should work on any platform. Did not work on my i5 4440 system, worked perfectly on amd am1 platform.16 Gb ram ddr4 @ 2199 bt, it says only for intel does that mean it won't boot on Ryzen.
If you deep dive into intel processor datasheets they mention what kind of dram chips they support, and their configuration on a dram stick. I didn't dive deep into it at that time, however.
