SuperMicro 128GB DDR5 RDIMM

This NEMIX RAM module provides 128GB of DDR5 registered ECC memory in a single 288-pin stick. It runs at 5600MHz with CL46 latency and operates at 1.1V. The 4Rx4 organisation and Samsung, Micron or Hynix chips target SuperMicro server and workstation platforms.

Suited for SuperMicro capacity upgrades

This module fits administrators expanding memory in compatible SuperMicro systems that accept DDR5 RDIMMs. It is not for desktop PCs or laptops that require unbuffered UDIMMs, nor for boards limited to lower densities or different pin-outs.

Single-stick 128GB leaves slots open

The 1X128GB kit occupies one RDIMM slot, freeing remaining channels for further expansion. It needs a motherboard qualified for DDR5 5600 registered ECC memory and a power delivery capable of 1.1V operation.

Questions about this item

What server motherboard slot is required for the 288‑pin DDR5 RDIMM?

A 288‑pin DDR5 RDIMM slot on a Supermicro server or workstation motherboard is required for the module to fit and operate.

Can this 5600 MT/s CL46 module run in a system that currently uses 4800 MT/s DDR5 memory?

Yes, the module will downclock to the lowest speed supported by the platform, so it can operate alongside 4800 MT/s DDR5 memory.

How can I confirm the 128 GB module is detected at 5600 MT/s with ECC active?

Check the BIOS memory information or run a system tool such as dmidecode to verify 128 GB capacity, 5600 MT/s speed, CL46 latency and ECC enabled.
