Exact-match 768 GB DDR5 kit for GIGABYTE MZ73-LM0

This NEMIX RAM kit delivers 768 GB across six 128 GB DDR5-6400 RDIMMs with CL52 latency, 1.1 V operation and 2Rx4 registered ECC. It is built to the precise rank, voltage and timing the server memory controller expects for full-capacity recognition at rated speed.

Verify motherboard population rules and slot count

Consult the GIGABYTE MZ73-LM0 manual for supported capacities, approved DIMM population order and installation steps before ordering. The board requires 288-pin registered RDIMMs, not UDIMMs or SODIMMs, and population rules differ by model.

Registered ECC architecture enables full-slot

The registered buffer offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly to stop silent data corruption and unplanned reboots before they reach production.

Questions about this item

Does the kit include all six 128GB RDIMMs or must I purchase any modules separately?

The kit contains six 128GB DDR5 RDIMMs for a total of 768GB; no additional modules are required to reach that capacity.

Should I choose the 2Rx4 CL52 6400MHz registered ECC version or a different rank and latency for the GIGABYTE MZ73-LM0?

Select this 2Rx4 CL52 DDR5-6400 registered ECC kit; it matches the motherboard's required rank, voltage, timing and form factor for full-capacity recognition.

What does the DDR5-6400 PC5-51200 rating mean once the modules are installed in the server?

The memory will operate at 6400MT/s with CL52 latency at 1.1V, delivering the rated bandwidth and error-correction the platform expects.
