“AM5 platform won’t boot OS with 24 and 48GB DDR5 memory dimms” – update

It seems that the AM5 platform is not yet ready for the DDR5 memory modules with capacities of 24 and 48 GB. A user shows that he could enter the bios with an ASUS ROG Strix B650-E motherboard, but the system would not continue to boot.

MEGAsizeGPU’s Twitter account shows that its ROG Strix B650-E motherboard paired with a Ryzen 5 7600X processor with two individual 24GB dimms (Corsair Vengeance DDR5-5600 48GB) is unable to boot to the OS normally; it doesn’t get past the Boot Manager and shows an error. According to this user, AMD and motherboard manufacturers need to release a new bios version to fix this. It is visible that the bios is normally accessible, recognizes both modules and provides correct information about the speed and the total memory capacity.

In the past month, memory manufacturers like Corsair have started introducing and releasing DDR5 memory kits with individual 24 and 48GB dimms, enabling capacities up to 192GB. Manufacturers such as MSI and Gigabyte have already announced that their Intel 700 and 600 motherboards are specifically ready for the DDR5 modules, but they have not made such announcements for AMD platforms.

Technically, AMD’s Ryzen 7000 processors have a memory limit of 128GB, which was also the case for the twelfth and thirteenth generation Intel Core CPUs until recently. Now that these Intel processors can support up to 196GB, this may also become possible with AMD.

Update 9-3: In a tweet suggests chi11eddog, who previously released correct information about future MSI motherboards, that AMD is working to add support for 24GB modules with the future AGESA version 1.0.0.7. Currently 1.0.0.6 is the latest AGESA.
