AMD B650 system can’t boot with 24/48/96GB memory (yet)

Support for new memory capacities is already available with Intel platform.

Intel board makers have recently announced support for new 24GB, 48GB and 96GB memory on their 600 and 700 series. These new capacities allow nonstandard memory sizes to be used by consumer platforms that already support the latest DDR5 standard. Thanks to these new formats, users can now choose between configurations such as 2x24GB while retaining the full speed from dual-channel memory.

Hardware enthusiast MEGAsizeGPU bought one of these new Corsair Vengeance DDR5 kits with two 24GB modules. It is officially rated at 5600 MT/s and supports Intel XMP overclocking profiles. Surprisingly, despite no official support ASUS ROG Strix B650-E motherboard equipped with AMD Ryzen 5 7600X CPU actually loads the BIOS and shows correct capacity information of the modules, but the system still doesn’t boot.

The AMD platform officially supports up to 128GB memory, so using two 24GB, four 24GB and even two 48GB modules should still be within the specs. However, AMD is yet to enable the support for these formats, which would enable users to pick the middle ground between 2x16GB or 2x32GB capacity.
