Even though AMD's AM5 platform is designed to support all features of DDR5 memory modules, including CUDIMMs, the company's existing Ryzen 7000 cannot work with CUDIMMs at all, whereas Ryzen 8000, and Ryzen 9000-series CPUs do not fully support such modules. Nonetheless, AMD's AMD's AM5 infrastructure has everything to support clock unbuffered memory modules, according to Sourabh Dhir, product management lead for gaming and workstations, who spoke to Digital Trends.
As memory technology evolves, innovations include not only memory chips with a higher data transfer rate but also new DIMM technologies, such as CUDIMMs. In fact, JEDEC's standards presume that all memory modules featuring memory speeds of 6400 MT/s and higher are CUDIMMs (i.e., have a clock driver onboard to ensure cleaner signaling and stability at high transfer rates).
