For Ryzen 3000/5000, you want to limit yourself to <= DDR4-3600 since the Infinity Fabric clock (FCLK) can only go up to 1800. Going higher than 3600 will cause the FCLK:UCLK multipliter to become 1:2, halving the FCLK. Officially, only up to DDR4-3200 is supported. | |||
For most applications, memory speed has diminishing returns above 3000 so don't spend too much to get better speeds or latency. | |||
