Server Memory Upgrade

This NEMIX RAM module provides a 128 GB DDR5 6400 MHz CL52 2Rx4 ECC Registered RDIMM for the GIGABYTE MZ23-SU0 motherboard. It is built for servers that require registered ECC memory to run at full capacity and rated speed.

Build and Connector

The 288-pin RDIMM form factor fits only boards wired for registered DIMMs; it will not seat in UDIMM or SODIMM slots. Major OEM chips from Samsung, Micron or Hynix run at 1.1 V without a heat spreader, so airflow across the module is essential.

Interface Limits

DDR5 6400 (PC5-51200) at CL52 delivers the bandwidth the platform specifies, but population rules and maximum supported capacity vary by motherboard revision. Consult the system manual for approved DIMM order and slot limits before installation.

Questions about this item

Does the DDR5 6400 PC5-51200 interface limit the module to 6400 MT/s on the GIGABYTE MZ23-SU0?

The module is rated at DDR5 6400 PC5-51200 and will run at that speed when the motherboard memory controller supports the full data rate.

What physical slot and form factor does this 288-pin RDIMM require?

It requires a standard 288-pin DDR5 RDIMM slot; the registered form factor is not compatible with UDIMM or SODIMM sockets.

How is the 2Rx4 registered ECC module installed, and what step is often missed?

Align the notch with the key, press firmly until both retention clips click, then verify the population order in the GIGABYTE MZ23-SU0 manual for full 128 GB recognition.
