One of the advantages that memory in DDR5 format will have is that it will allow modules with a much higher capacity than DDR4. That's a guess, and it's one of the main selling points of DDR5 motherboards, which in the future will have 96GB dual-channel configurations, but at least on AMD's AM5 platform there are issues.
Recent reports indicate that AMD's latest AM5 platform is still in beta regarding support for high-capacity DDR5 memory. It appears to be unable to run 24GB and 48GB memory modules at this time, with evidence suggesting that users are unable to boot the operating system with either of these modules.
AMD motherboards do not support large capacity DDR5 memory
All Intel motherboards based on the LGA 1700 socket are compatible thanks to the latest BIOS updates released by motherboard manufacturers . However, in this same area, AMD seems to be lagging behind, giving Intel an advantage.
Twitter leaker MEGAsizeGPU obtained a 24GB Corsair Vengeance memory kit running at 5600 Mbps and compatible with Intel's XMP mode. It was installed in an ASUS ROG STRIX B650-E motherboard with an AMD Ryzen 5 7600X CPU. The motherboard was running the latest BIOS firmware , v.1222 (AGESA 1.0.0.5c). Although the BIOS correctly detected the two memory modules, the system failed to boot into Windows.
It is seen that AMD motherboard manufacturers have not yet offered a latest BIOS firmware that supports both 24GB and 48GB memory modules. AMD introduced EXPO support on their AM5 motherboards to rival Intel's XMP, but both can work on motherboards. Intel retains the speed advantage when it comes to memory support.
During AM5's pre-launch promotion, AMD promised that we would see dramatically increased speeds with the new AM5 platform overclocking specification. As of today, Intel's platform supports kits of over 8.000 Mbps, while AMD has yet to reach speeds of 7.000 Mbps. DDR5 memory will soon be a standard for the enthusiast and home audience, and will be the only format that will be marketed new once Intel releases its first CPUs that abandon DDR4 support. By then, AMD will need to improve its motherboards' support for DDR5.
