Add 32 GB of registered DDR5 memory to systems that support ECC RDIMM modules. Samsung M321R4GA3PB0-CWMXJ-R is specified as a refurbished DDR5-5600 module with ECC protection, giving server platforms registered memory architecture rather than unbuffered desktop DIMM operation. Its PC5-44800 designation identifies the DDR5-5600 performance class, while the 1.1 V operating voltage aligns with the stated DDR5 module specification. The module uses a 2Rx8 organization and the RDIMM form factor. These details matter when expanding a populated server: the host platform must support DDR5 registered memory, ECC operation, the required capacity per slot, and the intended memory population arrangement. Confirm the server platform supports this memory class before installation; RDIMMs are not interchangeable with every DDR5 DIMM type. This configuration combines 32 GB capacity, DDR5-5600 speed, ECC capability, 2Rx8 organization, and registered buffering in one module. The refurbished condition distinguishes the supplied unit from factory-new memory, while the electrical and memory-format specifications remain central to compatibility planning. It fits memory expansion or replacement work where the system requires a 32 GB ECC DDR5 RDIMM at the PC5-44800 speed grade.
