AMD is slowly improving the memory compatibility of its Ryzen platform and TechPowerUp
just noticed that the company broadened its
DDR4 compatibility list (PDF). The PDF lists DDR4-2133 to DDR4-3200 modules that have been tested by AMD to run reliably.
DDR4 memory speed has a significant impact on performance of Ryzen-powered machines beyond just added memory bandwidth. The clock speed at which the chip's internal InfinityFabric link ticks, is proportional to DRAM clock. This interconnect links the two quad-core complexes (CCXs) on the 14 nm "Summit Ridge" silicon on which the Ryzen socket AM4 processors are based. Among additions to AMD's revised memory compatibility list are brands that aren't necessarily based on Samsung b-die DRAM chips.
For optimal memory support on the Ryzen platform, you need to a motherboard BIOS that contains the AMD AGESA 1.0.0.6 CPU microcode update. Check your motherboard maker's website to see if the latest BIOS contains this update.
