Exact-match server upgrade

This NEMIX RAM module delivers 32 GB of DDR5 4800 registered ECC memory in a single 288-pin RDIMM. It is built for the GIGABYTE MZ23-SU0 motherboard where the memory controller expects 2Rx8 organisation, 1.10 V operation and CL40 timing. The registered buffer allows full-capacity population across every supported slot without signal degradation.

Thermals and power

The module runs at the standard DDR5 voltage of 1.10 V and carries no heat spreader, relying on chassis airflow for cooling. Registered buffering reduces the electrical load on the memory controller, helping keep system power draw predictable when all slots are populated. Silent operation is assured because the design has no moving parts.

Capacity and form factor

The single DIMM provides 32 GB in the 288-pin RDIMM form factor required by this platform; UDIMM or SODIMM modules will not fit or function. Buyers who need a different capacity or a non-ECC unbuffered module must select another part.

Questions about this item

How do I install the 288-pin RDIMM in the GIGABYTE MZ23-SU0 and which slot order should I follow?

Power down the server, open the chassis, align the notch on the 288-pin RDIMM with the slot key, press firmly until both ejector clips click, then populate DIMM slots in the exact sequence listed in the motherboard manual for registered ECC modules.

What maintenance will the registered ECC RDIMM need over its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts, so only keep the server air filters clean and verify ECC error counters in the system log during routine health checks.

What is the first limit reached when the 4800 MT/s RDIMM runs fully populated under sustained load?

The memory controller's maximum supported capacity per channel is reached before the 1.1 V modules hit thermal or signal-integrity limits, so total installed capacity is capped by the board's population rules.
