System-specific DDR5 RDIMM kit

This 512GB kit contains eight 64GB DDR5 5600 registered ECC modules built for the GIGABYTE MZ73-LM0 motherboard. The 2Rx4 organization and 1.10V operation match the board's memory controller requirements exactly. It is intended for administrators expanding a compatible server platform to its full rated capacity.

Pre-installation checklist

Verify the motherboard manual for approved DIMM population order and maximum supported capacity per slot before ordering. The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function. Confirm the system BIOS is updated to a version that recognizes this density and rank configuration.

Sustained-load behavior

Registered buffering reduces electrical load on the memory controller so all eight slots can run fully populated at the rated 5600 speed. ECC circuitry corrects single-bit errors continuously during long-running workloads. The modules operate without heat spreaders, relying on chassis airflow for thermal management.

Questions about this item

Does the 512GB kit arrive as eight 64GB modules or do I need to buy additional DIMMs?

The package contains eight 64GB RDIMMs for a total of 512GB; no extra modules are required.

Should I choose the 512GB 8×64GB kit or a smaller capacity for the GIGABYTE MZ73-LM0?

The 8×64GB kit fills all eight DDR5 slots on the MZ73-LM0 and matches the board's 2Rx4 registered ECC population rules for full-speed operation.

What does the DDR5 5600 CL46 rating mean once the memory is installed in the server?

The modules will run at 5600 MT/s with a CAS latency of 46 at 1.10V, delivering the rated PC5-44800 bandwidth when the motherboard is fully populated.
