Exact-Match 384GB DDR5 Kit

This 384GB kit contains four 96GB DDR5-4800 registered ECC RDIMMs built to the precise rank, voltage and timing the GIGABYTE MZ73-LM0 memory controller expects. The modules are recognised at full capacity and run at their rated speed without manual tuning.

Upgrading From Smaller Kits

Replacing a lower-capacity kit with this four-module set fills every supported slot at 4800MHz CL40 and 1.1V, delivering the maximum density the board allows. The jump is worth it when workloads need the full 384GB address space and registered buffering to keep every slot stable under load.

Build Integration Requirements

The 288-pin RDIMM form factor fits only boards wired for registered DDR5; it will not work in UDIMM or SODIMM slots. Registered architecture offloads the memory controller so all four slots run fully populated, while on-die ECC corrects single-bit errors before they reach production data.

Questions about this item

Will these 288-pin RDIMMs fit the GIGABYTE MZ73-LM0 memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the slots required by the GIGABYTE MZ73-LM0 motherboard.

What is the correct installation order for the four 96GB modules on the MZ73-LM0?

Consult the motherboard manual for the approved DIMM population sequence before installing all four 96GB modules.

Do the modules need any cooling maintenance since they have no heat spreader?

No heat spreader is included; ensure adequate chassis airflow over the bare modules for long-term stability.
