System-specific capacity

This NEMIX RAM kit delivers 512GB across four 128GB DDR5 RDIMM modules built for the Supermicro SYS-822GS-NB3RT. Registered ECC with a 2Rx4 organisation provides error correction and signal integrity required by enterprise workloads. The 288-pin form factor matches the server's memory slots exactly.

Sustained throughput behaviour

Operating at 6400MHz with CL52 latency, the modules maintain rated bandwidth during extended compute passes rather than throttling after a short burst. Registered buffering reduces electrical load on the memory controller, helping stability when all channels are populated. ECC corrects single-bit errors in flight without halting the workload.

Thermals, noise and power

Running at 1.1V, the kit draws minimal power for its density and has no heat spreaders, so airflow from the server chassis handles cooling directly. Passive operation adds no acoustic signature of its own. The low voltage and registered design keep per-module power modest under continuous load.
