Memory manufacturers have recently released DDR5 memory modules in 24GB and 48GB densities, providing PC enthusiasts with a unique item that offers 48GB (2x 24GB), 96GB (2x 48GB or 4x 24GB), and 192GB (4x 48GB) capacities. 

MEGAsizeGPU tested the Corsair Vengeance DDR5-5600 48GB (2x 24GB) memory kit on an AMD Ryzen 7000 "Zen 4" platform with an ASUS ROG Strix B650E-E Gaming motherboard (BIOS version 1222) and a Ryzen 5 7600X processor. While the machine could start the UEFI setup program, Windows wouldn't boot and halt with an error message indicating a hardware problem.

AMD Ryzen 7000 series processors technically have a 128 GB maximum memory size limit. Still, it's possible that firmware-level updates could enable support for 24GB and 48GB memory modules to at least operate under the 128GB limit. The introduction of 24GB memory modules provides PC enthusiasts with more options, offering a middle-ground between 32GB (2x 16GB) and 64GB (2x 32GB) using faster single-rank DIMMs (2x 24GB).
