Can current AMD motherboards use a single 24/48GB memory?

Previously, MSI, ASRock, Gigabyte, and ASUS announced that their Intel 600/700 series motherboards now support single 24GB and 48GB DDR5 memory modules, which means memory capacity will no longer follow the historical trend of increasing in powers of 2. Motherboards with 4 DIMM slots can now support up to 192GB of memory, up from 128GB, and those with 2 DIMM slots can support up to 96GB of memory, up from 64 GB. MSI and Gigabyte stated that their motherboards are compatible with the new memory without needing a BIOS update, while ASRock and ASUS released new firmware to support it. However, all these brands only mention support for Intel platforms and make no mention of AMD. Theoretically, achieving the same result on an AMD platform is not impossible.

Recently, Twitter user @Zed__Wang attempted to use Corsair’s newly released Vengeance DDR5-5600 24GB x 2 kits with an AMD Ryzen 5 7600X processor and ASUS ROG Strix B650E-E Gaming WiFi motherboard. Although the BIOS correctly recognized the memory, the system failed to boot without the latest BIOS update from the motherboard manufacturer.

Currently, there are few manufacturers in the market offering single 24GB and 48GB DDR5 memory modules, with only Corsair and Adata being among them. Corsair’s Vengeance series, which comes in RGB and non-RGB versions and has a frequency of 5600MHz, offers 48GB and 96GB kits that support Intel XMP 3.0 technology, but at a high price. As DDR5 memory rapidly develops, it is expected that 24GB and 48GB DDR5 memory modules will become more common, and AMD will likely follow up with support soon.
