NEMIX RAM
A 384GB DDR5 server memory kit with twelve 32GB registered ECC modules running at 4800MHz CL40 and 1.1V for ThinkMate Supermicro systems
This NEMIX RAM kit delivers 384GB across twelve 32GB DDR5 4800 CL40 288-pin ECC registered DIMMs. It is built for servers and workstations that require registered error-correcting memory in high-density configurations.
Registered signalling and on-die ECC protect data integrity under sustained multi-threaded workloads. The 1.10V operating voltage and CL40 latency are specified for stable operation at the rated PC5-38400 speed grade.
The kit is validated for the ThinkMate Supermicro SuperServer 521C-NR; systems needing unbuffered DIMMs, non-ECC modules or a different DDR generation should select alternate memory.

The modules are built with major OEM Samsung, Micron or Hynix DRAM and are rigorously stress tested under load before shipping, so no firmware updates or scheduled replacement are required during normal operation.
The registered ECC RDIMM design with 1Rx4 organisation and 1.10 V operation is validated for sustained server workloads, so thermal throttling or signal integrity limits are not reached under standard chassis airflow.
Each module runs at 1.1 V without a heat spreader, relying on system airflow; registered buffering keeps signal power low, so the kit adds minimal heat and no audible noise beyond normal server fans.
