  • 384 GB total capacity from eight 48 GB modules for maximum server density
  • DDR5 6400 speed with CL52 latency delivers rated throughput on the GIGABYTE MZ73-LM0
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 10 V operation at 2Rx8 rank matches the board's memory-controller requirements exactly
  • 288-pin RDIMM form factor fits the motherboard's DDR5 slots without adapters

Exact-match server memory kit

This 384GB kit contains eight 48GB DDR5 RDIMM modules built for the GIGABYTE MZ73-LM0 motherboard. Registered ECC architecture and 2Rx8 organisation let the board recognise full capacity at the rated 6400 speed. It targets administrators who need maximum density in a validated configuration.

Installation notes

Each module uses the standard 288-pin RDIMM form factor and seats in the board's DDR5 slots without tools. The kit is spec-matched to the motherboard's population rules, so the correct slot order must be followed from the system manual. Mixing these registered DIMMs with unbuffered UDIMM or SODIMM types will prevent the system from posting.

DDR5 platform limits

DDR5 RDIMM topology supports high capacities per channel, but the memory controller still enforces maximum ranks per channel and total system capacity. Exceeding those limits or populating slots in an unsupported order will reduce speed or disable modules. The motherboard manual defines the exact population sequence and any BIOS settings required for full 6400 operation.

Questions about this item

How do I verify the kit is running at DDR5 6400 CL52 1.10V on my GIGABYTE MZ73-LM0 after installation?

Enter the BIOS and confirm the memory frequency reads 6400 MT/s with timings of CL52 and a voltage of 1.10V; the registered ECC design ensures the board recognises all 384GB across the eight slots.

What comes in the box and do I need any extra parts for the GIGABYTE MZ73-LM0?

The package contains the 384GB kit of eight 48GB 288-pin DDR5 RDIMMs; no additional modules, cables or brackets are required for the MZ73-LM0.

Which capacity version should I choose for the MZ73-LM0 if I want the full 384GB configuration?

Select the 384GB (8 x 48GB) kit, part number MR51200-4828K8, to populate all supported DIMM slots with matching 2Rx8 registered ECC modules at DDR5 6400.
