NEMIX RAM
A 64 GB DDR5 registered ECC memory kit of four 16 GB modules running at 4800 MT/s with CL40 latency for SuperMicro X13SET-G and X13SET-GC motherboards
This 64GB kit contains four 16GB DDR5 4800 ECC registered DIMMs validated for SuperMicro X13SET-G and X13SET-GC motherboards. It targets administrators and integrators who need reliable, high-capacity memory for server and workstation workloads. The registered design with on-die ECC helps maintain data integrity under sustained load.
Each module uses a 288-pin RDIMM form factor and operates at 1.1V with CL40 latency. The 1Rx8 organisation and major OEM DRAM chips from Samsung, Micron or Hynix provide consistent electrical characteristics. No heat spreaders are fitted, so airflow across the PCB is unimpeded in dense chassis layouts.
Running at 1.1V reduces power draw per module compared with earlier DDR generations while delivering 4800 MT/s throughput. The absence of heat spreaders means thermal performance depends on case airflow, but registered buffering and ECC logic add minimal overhead. Under typical server loads the kit runs cool and quiet without active cooling on the memory itself.
