System-Specific DDR5 Kit

This NEMIX RAM kit delivers 192 GB of DDR5 memory across twelve 16 GB registered DIMMs. It is built for IT professionals upgrading compatible Supermicro servers and workstations that require ECC registered modules.

Registered ECC at 4800 MT/s

The decisive specification is the DDR5 4800 (PC5-38400) registered ECC design with CL40 latency and 1Rx8 organisation. Only systems that accept 288-pin DDR5 RDIMMs at this speed and voltage will recognise the full capacity.

Low-Voltage Registered Operation

Each module runs at 1.1 V without a heat spreader, relying on the server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw and acoustic impact low in typical rackmount deployments.

Questions about this item

What does the 4800 MT/s speed mean when the kit is installed in a Supermicro server?

The modules run at DDR5 4800 MT/s (PC5-38400) with CL40 latency and 1.1 V, delivering the rated throughput once the platform enables the DDR5 4800 profile.

How does the 288-pin RDIMM interface limit the configuration on the X13SEDW-F motherboard?

Each 288-pin DDR5 RDIMM slot accepts one registered module; the kit fills 12 slots with 1Rx8 16 GB sticks for a total of 192 GB.

Will the 12 modules fit the SYS-111C-NR and SYS-521C-NR chassis without extra hardware?

The 288-pin RDIMM form factor matches the DIMM sockets on the listed Supermicro UP SuperServer systems; no adapters or brackets are required.
