Server Memory Kit

This NEMIX RAM kit delivers 384GB across six 64GB DDR5 4800 CL40 ECC RDIMM modules. It is built for SuperMicro UP SuperServer SYS-111C-NR and SYS-521C-NR systems using the X13SEDW-F motherboard. The registered design with on-die ECC targets enterprise workloads that demand data integrity and high capacity.

Build Integration

Each 288-pin RDIMM operates at 1.1V with a 2Rx4 organisation, reducing electrical load on the memory controller. The registered buffer allows the platform to populate all slots without signal degradation. No heat spreaders are fitted, so airflow across the motherboard must handle thermal management.

Upgrade Context

This kit replaces lower-capacity DDR5 RDIMM sets or fills empty slots on the supported SuperMicro platforms. The jump is worth it when virtualisation, database or compute workloads exceed the current memory ceiling and the motherboard qualifies 64GB 2Rx4 modules at 4800MT/s.

Questions about this item

What is the CAS latency that governs response time under sustained load?

The modules run at CL40, so every memory request waits forty cycles before data is returned.

How much power does the kit draw and how hot does it get when the server runs continuously?

Each DIMM operates at 1.10 V; with no heat spreader fitted, airflow through the chassis must carry away the heat generated at that voltage.

Which motherboard must already be installed for this 384 GB kit to function?

It is validated for SuperMicro UP SuperServer SYS-111C-NR, SYS-521C-NR and X13SEDW-F motherboards.
