The Samsung M321R9GA0BB0-CQK is a 128 GB DDR5 registered memory module (RDIMM) rated at 4800 MT/s. It uses a 3DS (Three Die Stack) module architecture and supports ECC (Error-Correcting Code). This makes it suited to systems where high memory capacity and data integrity are required.
Key specifications include a 288-pin form factor, a 64-bit data width and registered DIMM design. The registered design buffers signals between the memory controller and the DRAM. The 3DS architecture stacks DRAM dies within each package, enabling high capacity on a single module.
Registered ECC DDR5 modules of this type are typically used in servers and workstations that support DDR5 RDIMMs. Common workloads include virtualisation, databases and other memory-intensive applications in data centre and enterprise environments.
