Memory Technology with Dual Channels - DDR4 DIMM slots available. Compatible with AMD Ryzen series CPUs (Matisse) for DDR4 speeds 3200/2933/2667/2400/2133, both ECC and non-ECC, without buffering. Compatible with AMD Ryzen series CPUs (Pinnacle Ridge) for similar speeds and memory types. Compatible with AMD Ryzen series CPUs (Picasso) for 2933/2667/2400/2133 non-ECC, un-buffered memory. Compatible with AMD Ryzen series CPUs (Summit Ridge) for 3200+(OC)/2933(OC)/2667/2400/2133 ECC & non-ECC, un-buffered. Maximum system memory capacity is 64GB. Each DIMM slot features a 15μ Gold contact. For Ryzen series CPUs (Picasso and Raven Ridge), ECC support is available only on PRO CPUs. See the table for AMD non-XMP memory frequency details. System usage under Windows 32-bit OS may have a size restriction of less than 4GB due to OS constraints. Windows 64-bit with 64-bit CPU does not impose this limit.

On the motherboard's support site they provide lists of authorized vendors and compatible sticks for the board or CPU. Your choices aren't restricted to this list, but you can use it if needed.

Find something with DDR4 listed on the package, but I haven't noticed a RAM stick failing because it wasn't in the QVL.
