NEMIX RAM 16GB DDR5 4800 ECC RDIMM

This 16GB DDR5 4800 ECC registered DIMM is built for Supermicro SuperWorkstation SYS-551A-T and Super X13SWA-TF motherboards. It targets IT professionals and system builders who need validated server memory for mission-critical workloads. The module uses major OEM chips from Samsung, Micron or Hynix. It operates at 1.1V with a CL40 latency profile.

Installation notes and common issues

Installation follows standard 288-pin DDR5 RDIMM procedure and typically takes minutes. Always consult the motherboard manual for slot population rules and BIOS settings. Common issues include mixing registered with unbuffered modules or exceeding the platform's supported rank count per channel. Verify that the system requires registered ECC memory before fitting.

Pre-order compatibility checks

Confirm the target system is a Supermicro SuperWorkstation SYS-551A-T or uses the Super X13SWA-TF motherboard. Ensure the platform supports DDR5 4800 registered ECC DIMMs at 1.1V. Check available 288-pin slots and maximum memory capacity per channel. Validate that the BIOS version supports 1Rx8 organization and PC5-38400 speed.

Questions about this item

How do I confirm the 16GB DDR5 4800 module is running at CL40 1.10V after installing it in my Supermicro SYS-551A-T?

Enter the system BIOS or UEFI after power-on and check the memory configuration screen; it should report 4800 MT/s, CL40 timings and 1.10 V for the installed RDIMM.

What does the package contain and is anything else required for installation?

The box includes one 16GB 288-pin DDR5 ECC RDIMM; no extra cables, brackets or cooling parts are needed — just an available RDIMM slot on the compatible Supermicro motherboard.

Which capacity and rank should I choose if I want a single 1Rx8 module for this platform?

This part number MR38400-618K1 is a single 16GB 1Rx8 RDIMM; select it when you need one registered ECC module of that density and organisation.
