NEMIX RAM 256GB (2x128GB) DDR5 6400MHz CL52 2Rx4 1.1V ECC RDIMM Supermicro SYS-822GS-NB3RT memory upgrade

System-specific DDR5 server memory

This 256 GB kit contains two 128 GB DDR5 ECC registered DIMMs built for the Supermicro SuperServer SYS-822GS-NB3RT. Each module runs at 6400 MHz with a CAS latency of 52 and operates at 1.1 V. The 288-pin RDIMM form factor and 2Rx4 organisation match the platform’s memory architecture.

ECC and registered buffering

Error-correcting code detects and corrects single-bit errors while the registered buffer reduces electrical load on the memory controller. Together they protect data integrity and allow the server to populate all supported slots without signal degradation. No heat spreader is included, relying on the chassis airflow design.

Capacity headroom for virtualisation workloads

The dual-rank configuration delivers 256 GB total capacity, providing ample room for large virtual-machine fleets, in-memory databases or container clusters. Workloads that exceed this limit or require higher memory frequencies will need a platform with greater DIMM-slot count or faster memory support.
