Exact-fit 48 GB DDR5-6400 for GIGABYTE MZ73-LM2

This NEMIX RAM module is a registered ECC RDIMM built to the precise speed, voltage, and rank the GIGABYTE MZ73-LM2 memory controller expects. It installs as a single 288-pin DDR5 DIMM and is recognised at full capacity without manual tuning.

48 GB capacity with registered ECC headroom

The 48 GB density suits multi-threaded server workloads such as virtualisation, databases, and large in-memory datasets. Registered buffering lets every slot run fully populated at the rated 6400 MT/s, while on-die ECC corrects single-bit errors before they reach the OS.

Registered RDIMM build with 288-pin DDR5 keying

Major-brand DRAM from Samsung, Micron, or Hynix operates at 1.1 V with CL52 latency and no heat spreader, keeping the form factor slim for dense chassis. The 2Rx8 organisation matches the board's population rules, so the DIMM seats securely in the standard DDR5 RDIMM slot.

Questions about this item

Will this 48GB DDR5 6400 CL52 1.1V 2Rx8 ECC RDIMM work alongside existing DDR5 RDIMMs in my GIGABYTE MZ73-LM2?

Yes, it matches the board's required DDR5 6400 PC5-51200 2Rx8 registered ECC 1.1V specification. For stable operation, install modules in the population order listed in the motherboard manual and ensure all slots use identical rank, voltage and timing.

How can I verify the module is running at DDR5 6400 with CL52 and ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory speed shows 6400 MT/s, CAS latency 52, voltage 1.10V and ECC status enabled. The OS should also report the full 48GB capacity and registered DIMM type.

What comes in the box and do I need any extra parts to install this 288-pin RDIMM?

The package contains the 48GB DDR5 6400 CL52 1.1V 2Rx8 ECC RDIMM only. No heat spreader, cables or tools are included. The motherboard provides the 288-pin RDIMM slots; no additional hardware is required for installation.
