Apacer mentions in a document that Ryzen 7000 series ships with DDR5-5200 memory, which is 400 MHz faster than JEDEC specifications and the Intel Alder Lake architecture. 

The chart also reveals that DDR4 is not supported and that EPYC Genoa supports DDR5-5200 natively. They are both based on AMD Zen4 microarchitecture. AMD is currently developing a technology dubbed EXPO, basically an SPD extension standard rivaling Intel XMP 3.0, with fine-grained AMD memory controller architecture-specific parameters. 

Lower down in the Apacer presentation it reveals EPYC Genoa CPUs will natively support DDR5-5200. The Socket SP5 CPUs support 12-channel DDR5 memory (24 sub-channels). The Ryzen 6000 "Rembrandt" mobile CPUs already include dual-channel DDR5-4800 and LPDDR5-6400 memory interfaces. AMD Ryzen 7000 "Raphael" CPUs natively support DDR5-5200 memory speed, therefore no UEFI adjustments are required.
