NEMIX RAM 384GB (6 x 64GB) DDR5 6400 ECC RDIMM 2Rx4 1.1V

384GB DDR5 6400 ECC RDIMM kit

This 384GB kit contains six 64GB registered DIMMs built for DDR5 6400 servers. It targets data-centre and workstation platforms that require error-correcting memory at PC5-51200 speeds. The modules are not compatible with standard desktop or laptop motherboards. Buyers needing non-ECC or unbuffered memory for consumer systems cannot use this kit.

Capacity and headroom

Six ranks of 2Rx4 organisation deliver 384GB total capacity, suited for virtualisation clusters, large databases and in-memory analytics. CAS latency of 52 at 6400 MT/s provides deterministic timing for latency-sensitive workloads. The kit reaches its limit when a platform demands higher frequencies or lower latencies than the rated specification. Applications requiring more than 384GB per socket must populate additional channels or select higher-density modules.

Build and daily implications

Registered buffering and on-die ECC protect data integrity across 288-pin slots in multi-socket chassis. Operating at 1.1V reduces power draw per module compared to higher-voltage DDR5 variants. Major OEM Samsung, Micron or Hynix DRAM ensures consistent supply quality. Installers must verify that the target server board supports DDR5 6400 RDIMM population rules and 2Rx4 rank configuration before deployment.
