NEMIX RAM
A 192 GB DDR5 registered ECC memory kit of six 32 GB modules running at 4800 MT/s with CL40 latency for SuperMicro X13SEW motherboards
This 192GB kit contains six 32GB DDR5 4800 CL40 ECC RDIMM modules built for SuperMicro X13SEW-TF and X13SEW-F motherboards. It targets IT professionals and system integrators who need registered memory with error correction for server and workstation workloads. The modules operate at 1.1V and use a 288-pin form factor with 1Rx4 organisation.
Each stick is a registered DIMM carrying on-die ECC and a parity bit for command/address lines, sourced from Samsung, Micron or Hynix die. The registered buffer reduces electrical load on the memory controller, allowing all six slots to be populated without signal degradation. No heat spreaders are fitted, relying on chassis airflow for cooling.
The 192GB total handles large virtual machine counts, in-memory databases and heavy container orchestration with headroom for simultaneous workloads. Six populated channels saturate the platform’s memory bandwidth at 4800 MT/s, so adding further capacity would require a motherboard with more slots or higher-density modules. Systems needing more than 192GB or faster transfer rates must look beyond this kit.

No firmware updates are required for these DDR5 RDIMMs, and memory modules do not have a scheduled replacement interval.
The CL40 CAS latency at 1.10 V is the primary timing constraint during sustained operation.
Each module operates at 1.10 V with no heat spreader, so total power draw stays low and cooling is handled by normal server airflow.
