Question: are all ddr4 ram compatible with ryzen?
Answer: the amd AM4 motherboards ( A320, B350, X370, B450 and X470) only work with DDR4 ram. ... All ddr4 ram should work but try ro get two sticks of ddr4 3000 or faster. (a kit) ryzen cpu's, and the graphics cores, like faster ram so dont cheap out with 2400 mhz.
