Capacity and form factor

This 576GB kit delivers twelve 48GB DDR5 RDIMM modules built to the exact 288-pin registered ECC specification the GIGABYTE MZ73-LM2 motherboard requires. It targets administrators who must populate every slot at full rated speed without trial-and-error compatibility work.

Upgrade path

The kit replaces partial or mixed-capacity populations that force the memory controller to down-clock or disable ranks, and it avoids the instability of unbuffered UDIMMs in a registered-only platform. The jump is worth it when the server must run all channels fully populated at DDR5-6400 with error correction active.

Workload headroom

Registered buffering and on-die ECC keep 576GB addressable under sustained load, supporting large in-memory databases, virtualization hosts, and checkpoint-restart workloads. Headroom ends when the platform’s maximum supported capacity per socket or per channel is reached, or when an application demands bandwidth beyond the PC5-51200 data rate.

Questions about this item

Will these 288-pin DDR5 RDIMM modules fit the GIGABYTE MZ73-LM2 motherboard slots?

Yes, the kit is verified for the GIGABYTE MZ73-LM2 and uses the 288-pin RDIMM form factor that board requires, not UDIMM or SODIMM.

What population order should I follow when installing all 12 modules on the MZ73-LM2?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first for full 576GB recognition.

Do these registered ECC modules need any firmware updates or periodic re-calibration during their service life?

No firmware updates or re-calibration are required; the registered ECC design handles error correction automatically, and the modules carry a lifetime replacement warranty.
