NEMIX RAM 256GB (4x64GB) DDR5 6400MHz CL52 2Rx4 ECC RDIMM for Supermicro SYS-822GS-NB3RT memory upgrade

Purpose-built server kit

This 256GB kit contains four 64GB DDR5 registered DIMMs built for the Supermicro SYS-822GS-NB3RT platform. ECC and registered buffering provide the error correction and signal integrity required in multi-socket server workloads. The modules operate at the standard 1.1V DDR5 voltage without a heat spreader. System administrators upgrading that specific SuperServer model use this kit to reach the platform's maximum supported capacity.

Decisive specification

Registered ECC RDIMM with a 2Rx4 organisation is the single attribute that determines compatibility with the target Supermicro system. Unbuffered or non-ECC modules will not function in this server architecture. The CL52 latency at 6400MHz matches the memory controller specification for the platform. Only modules meeting this exact registered ECC profile will initialise correctly.

Capacity and headroom

Four 64GB ranks deliver 256GB total, filling the available DIMM population for the qualified configuration. This capacity handles large in-memory databases, virtualization host consolidation and HPC working sets that exceed smaller footprints. Workloads requiring more than 256GB per node must move to a platform with additional memory channels or higher-density modules. The kit leaves no free slots for further expansion on this system.
