  • 288 GB total capacity from six 48 GB modules for high-density server workloads
  • DDR5 6400 speed with CL52 latency matches the board's rated memory controller timing
  • Registered ECC RDIMM design offloads the controller and corrects single-bit errors on the fly
  • 1 V operating voltage meets the exact power requirement for stable full-population operation
  • Verified compatibility with the GIGABYTE MZ73-LM1 motherboard for guaranteed recognition at full capacity

Exact-fit 288GB DDR5-6400 RDIMM kit

This 288GB kit contains six 48GB DDR5-6400 PC5-51200 registered ECC modules. Each DIMM runs at 1.1V with CL52 timing and a 2Rx8 organisation. The modules are built to match the GIGABYTE MZ73-LM1 motherboard memory controller expectations.

Suited for fully populated MZ73-LM1 servers

Administrators who need the full 288GB capacity across every slot will benefit from the registered buffer and on-die ECC. Builders using consumer UDIMM or SODIMM platforms cannot install these 288-pin RDIMMs. Systems limited to lower densities or non-ECC memory should look elsewhere.

Kit delivers six matched modules

The package supplies all six 48GB RDIMMs in a single validated set, removing the risk of mixing ranks or timings. No heat spreaders are included, so airflow in dense chassis remains unobstructed. No additional software or cables are bundled.

Questions about this item

What motherboard must I already own for this 288GB DDR5 6400 ECC RDIMM kit to work?

The kit is validated for the GIGABYTE MZ73-LM1 motherboard that supports DDR5 6400 PC5-51200 Registered ECC memory in a 288-pin RDIMM form factor.

How will these six 48GB 2Rx8 Registered modules behave if I keep older DDR5 RDIMMs installed alongside them?

Mixing ranks, speeds, or voltages can prevent the memory controller from training at 6400 MT/s; the board manual should be consulted for approved population rules before adding different modules.

How can I confirm the kit is running at its rated 6400 MT/s CL52 1.10V after installation?

Enter the system BIOS or UEFI and verify the memory frequency reads 6400 MT/s, CAS latency shows CL52, and the DIMM voltage reports 1.10V with all six slots populated.
