AMD AM5 Platform Still In Beta-State When It Comes To 24 & 48 GB DDR5 Memory Support

Memory manufacturers recently introduced new 24 GB & 48 GB DDR5 memory modules which are fully supported by Intel's 600 and 700-series platforms but it looks like AMD's latest AM5 platform is still in the Beta phase when it comes to offering similar support.

The 24 GB and 48 GB memory modules allow users to install more capacities within their PCs compared to the 16 GB and 32 GB modules. These kits can allow as much as up to 192 GB DDR5 capacities on Intel platforms whereas only 128 GB was possible with 32 GB memory modules. It seems like all Intel motherboards based on the LGA 1700/1800 socket have good support baked into them thanks to the latest BIOS released by motherboard manufacturers but the AMD camp seems to be a bit behind.

Twitter leaker, MEGAsizeGPU, managed to get his hands on a Corsair Vengeance 24 GB memory kit which operates at 5600 Mbps and supports Intel XMP mode. The kit was installed on an ASUS ROG STRIX B650-E motherboard with an AMD Ryzen 5 7600X CPU. The motherboard was running on the latest BIOS firmware which is v.1222 (AGESA 1.0.0.5c) and while the BIOS was able to detect the two memory modules fine, the system was unable to boot into the Windows OS.

This shows that AMD's motherboard partners have some work to do in regard to offering the newest BIOS firmware to support the 24 GB and 48 GB memory modules. AMD introduced EXPO support on its AM5 motherboards to rival Intel's XMP but both can work on the motherboards however, it looks like Intel retains the speed advantage when it comes to memory support.

Back during AM5's inception, AMD promised that we will see speeds that we couldn't think would be possible with the new overclocking spec on the AM5 platform however Intel's platform supports kits beyond 8000 Mbps while AMD struggles to hit even 7000 Mbps speeds.
