Exact-match upgrade for GIGABYTE MZ73-LM2

This NEMIX RAM kit delivers 384GB across twelve 32GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency. Registered ECC architecture ensures the memory controller recognises every module at full capacity and rated speed. It is built for servers and workstations that require maximum registered DIMM population on this specific motherboard.

Registered RDIMM form factor with 288-pin layout

The 2Rx8 organisation and 1.10V operating voltage match the board's electrical requirements exactly. Registered buffering reduces electrical load on the memory controller when all slots are populated, while ECC corrects single-bit errors in flight. No heat spreaders are fitted, so airflow in the chassis must be sufficient for dense configurations.

Enterprise stability under sustained load

Registered buffering and on-die ECC maintain data integrity during continuous operation at DDR5 6400 speeds. The low 1.10V voltage helps limit power draw per module in a fully populated system. Buyers needing unbuffered UDIMMs, SODIMMs, or non-ECC memory for desktop platforms cannot use this kit.

Questions about this item

What speed does the DDR5 6400 interface actually run at when all twelve slots are populated?

The kit is rated for DDR5 6400 (PC5-51200) at CL52 and 1.1 V. Registered buffering lets the memory controller drive all twelve 2Rx8 modules at that speed without downclocking.

Will these 288-pin RDIMMs physically fit the GIGABYTE MZ73-LM2 DIMM slots?

Yes. The board requires 288-pin DDR5 RDIMMs; this kit supplies exactly twelve 288-pin registered modules with the correct key notch and 1.1 V signalling.

What is the correct installation order for the twelve modules on the MZ73-LM2?

Populate the twelve slots in the sequence listed in the motherboard manual (typically CPU0 channels A–D then CPU1 channels E–H). Skipping a slot or mixing ranks breaks the registered signal chain and prevents POST.
