NEMIX RAM 16GB DDR4 3200 ECC RDIMM 1Rx4 CL22 Supermicro H12DST-B EPYC

Server-grade DDR4 ECC module

This 16 GB DDR4 3200 RDIMM delivers registered ECC memory for Supermicro H12DST-B platforms built on AMD EPYC processors. The single-rank 1Rx4 organisation runs at 1.2 V with CL22 latency and fits a standard 288-pin DDR4 slot. It targets administrators who need validated, error-correcting capacity for always-on workloads.

Registered design for multi-DIMM stability

Registered signalling reduces electrical load on the memory controller, allowing the board to populate multiple slots without timing degradation. ECC protection detects and corrects single-bit errors to keep services running. The module requires a motherboard that supports DDR4 RDIMM ECC at 3200 MT/s and will not operate in consumer UDIMM-only systems.

16 GB per stick with headroom for expansion

One 16 GB module fills a single slot and leaves remaining channels open for identical sticks to reach the platform’s maximum supported capacity. The PC4-25600 rating sustains 3200 MT/s throughput for virtualisation, database and container workloads. Systems that demand higher per-module density or faster speeds will need different modules.
