32GB DDR5 4800 ECC RDIMM for SuperMicro servers

This NEMIX RAM module delivers 32GB of DDR5 4800 memory with ECC and registered buffering. It operates at 1.1V with CL40 latency in a 288-pin 1Rx4 configuration. The part is validated for SuperMicro UP SuperServer SYS-111C-NR and SYS-521C-NR systems with X13SEDW-F motherboards.

Suits admins adding ECC capacity to qualified

Builders needing unbuffered UDIMMs or non-ECC memory for desktop boards cannot use this registered DIMM. Systems that require RDIMM support and ECC error correction will accept this module; platforms without registered memory support will not.

Registered DDR5 with on-die ECC at 4800 MT/s

The registered buffer and ECC logic maintain data integrity under sustained server workloads. The 4800 MT/s rating matches the PC5-38400 specification for compatible SuperMicro motherboards.

Questions about this item

What slot type does the 288-pin DDR5 RDIMM need on a SuperMicro SYS-111C-NR or SYS-521C-NR?

It fits a standard 288-pin DDR5 RDIMM slot on the X13SEDW-F motherboard used in those SuperMicro SuperServer systems.

Which orientation step is most often missed when seating this registered ECC module?

Align the off-centre notch on the 288-pin edge connector with the key in the slot, press straight down until both retention clips click, and verify the module sits evenly.

When should the 32 GB 1Rx4 CL40 1.10 V module be replaced in a server running continuous ECC workloads?

Replace it if the system logs show rising corrected error counts, fails memory diagnostics, or becomes unstable after firmware updates.
