  • 64 GB total capacity from two 32 GB modules for high-density server workloads
  • DDR5-4800 (PC5-38400) speed at CL40 latency delivers rated bandwidth out of the box
  • ECC and registered design corrects single-bit errors and offloads the memory controller
  • 1 V operation with 2Rx8 organization matches the board's voltage and rank requirements
  • 288-pin RDIMM form factor fits the GIGABYTE MZ73-LM2 motherboard exactly

Exact-fit DDR5 ECC RDIMM for GIGABYTE MZ73-LM2

This 64 GB kit (2 x 32 GB) delivers DDR5-4800 (PC5-38400) registered ECC memory at 1.1 V and CL40. The 2Rx8 288-pin RDIMM modules match the motherboard's required form factor, rank, voltage and timing so the server recognises full capacity at rated speed.

Thermals power and noise

Registered ECC modules run at a low 1.10 V without heat spreaders, keeping power draw modest in normal server workloads. Passive cooling relies on chassis airflow; no active fans or pumps are included, so acoustic output depends entirely on the host system's fan curves.

What the kit changes

Populating both slots with matched registered DIMMs offloads the memory controller, allowing fully populated operation at full capacity while ECC corrects single-bit errors on the fly. The kit contains only the two memory modules; no extra cables, software or mounting hardware are supplied.

Questions about this item

How do I install the 288-pin RDIMM modules in the GIGABYTE MZ73-LM2 and what step is often missed?

Power off the server, open the chassis, and insert each 32 GB module into the slots listed first in the motherboard manual; the step most people skip is verifying the exact population order so the memory controller recognises the full 64 GB at 4800 MHz.

What maintenance or replacement will the DDR5 ECC RDIMM kit need over time?

No routine maintenance is required; if a module fails the lifetime replacement warranty covers a direct swap, and ECC continues correcting single-bit errors without user intervention.

What limit appears first when the registered 2Rx8 kit runs sustained workloads?

The memory controller's maximum supported capacity and ranked-population rules cap usable memory before thermal or voltage limits become a factor.
