  • 10 V operation matches the platform's voltage spec for reliable power delivery
  • Verified compatible with the GIGABYTE MZ73-LM0 motherboard for exact-fit installation

Exact-Match Server Upgrade

This 384GB kit delivers eight 48GB DDR5 4800 RDIMM modules built to the precise rank, voltage and timing the GIGABYTE MZ73-LM0 memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors on the fly for production stability.

Verify Population Rules

Server and motherboard memory support varies by model. Consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase. The 288-pin Registered form factor is required; UDIMM or SODIMM modules will not fit.

Thermals Power And Noise

Modules operate at 1.1V without heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during full-population operation. No active cooling components are present, so acoustic output depends entirely on system fans.

Questions about this item

Does the 384GB kit ship as eight 48GB modules or do I need to buy any extra DIMMs?

The kit contains eight 48GB DDR5 RDIMM modules for a total of 384GB; nothing else is required to reach that capacity.

Should I choose this 4800 CL40 2Rx8 kit or a different speed or rank for the MZ73-LM0?

This 4800 CL40 2Rx8 Registered ECC kit matches the motherboard's validated spec, so it will be recognised at full capacity and rated speed.

What does the DDR5-4800 rating mean once the modules are installed in the server?

The memory will run at 4800 MT/s with CL40 latency at 1.1V, delivering the bandwidth and error-correction the platform expects.
