NEMIX RAM 512GB 8x64GB DDR5 4800 CL40 2Rx4 ECC RDIMM SuperMicro FatTwin X13SEFR-A

Server memory kit

This 512 GB kit supplies eight 64 GB DDR5 registered DIMMs built for SuperMicro FatTwin SuperServer systems SYS-F521E3-RTB, SYS-F511E2-RT and X13SEFR-A. ECC and registered buffering protect data integrity in mission-critical workloads. The modules run at 4800 MT/s with CL40 latency at 1.1 V.

288-pin registered DIMMs

Each stick uses a 288-pin DDR5 RDIMM form factor with 2Rx4 organisation and no heat spreader, so they fit standard server DIMM slots without clearance issues. Major OEM Samsung, Micron or Hynix chips are rigorously stress-tested under load before shipping. The registered design reduces electrical load on the memory controller for stable operation in dense configurations.

512 GB total capacity

The eight-module population fills all available channels on supported FatTwin nodes, delivering maximum memory bandwidth for virtualization, database and HPC tasks. Systems needing less capacity or non-ECC memory cannot use this kit. Buyers requiring different speeds, voltages or form factors should verify their platform specifications first.
