Capacity & Purpose

This 384GB kit contains twelve 32GB DDR5 4800 registered ECC modules built for SuperMicro UP SuperServer SYS-111C-NR and SYS-521C-NR systems. It targets administrators who need maximum memory density for virtualization, database or high-performance computing workloads on those platforms.

Sustained Load Behaviour

Each module runs at 1.1V with CL40 latency and a 1Rx4 organisation using major OEM Samsung, Micron or Hynix chips. Registered buffering and on-die ECC maintain data integrity during continuous heavy throughput without generating excess heat, as no heat spreaders are fitted.

Pre-Installation Checks

Verify that your motherboard is the X13SEDW-F and that all twelve 288-pin DDR5 RDIMM slots are free and support 384GB total capacity. Confirm the system BIOS is current enough to initialise twelve 1Rx4 registered modules at 4800 MT/s. Ensure your chassis airflow can cool bare modules under full load.

Questions about this item

How much power does the 1.10V DDR5 4800 kit draw when the server runs continuously?

Each 32 GB module operates at 1.10 V; total power depends on the number of populated slots and the workload, so consult the platform’s power budget for a precise figure.

Which motherboard and CPU combination must I already own for this 12-module kit to function?

The kit is validated for SuperMicro UP SuperServer SYS-111C-NR, SYS-521C-NR and the X13SEDW-F motherboard with a compatible DDR5-capable processor.

Can I mix these 1Rx4 registered ECC DIMMs with different-rank DDR5 modules already in the system?

Mixing ranks is not recommended; the platform’s memory controller expects identical 1Rx4 registered ECC modules across all 12 slots for stable operation.
