  • 64 GB capacity from four 16 GB modules for full server memory population
  • DDR5 6400 speed with CL52 latency runs at rated frequency on the GIGABYTE MZ73-LM2
  • Registered ECC RDIMM design offloads the controller and corrects single-bit errors automatically
  • 1 V operation matches the motherboard's voltage requirement for stable full-load performance
  • 288-pin DDR5 form factor fits the board's memory slots without adapters or mismatches

Exact-match server memory kit

This 64GB kit contains four 16GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. The modules use 1Rx8 registered ECC architecture specified for the GIGABYTE MZ73-LM2 motherboard. Each 288-pin DIMM is validated for full-capacity recognition at rated speed.

Registered ECC changes stability

Registered buffering offloads the memory controller so all four slots run fully populated without signal degradation. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption that would otherwise crash workloads or corrupt results. The 1Rx8 organisation matches the board's population rules exactly.

Capacity headroom for virtualization

Sixty-four gigabytes across four channels supports multiple virtual machines, container fleets, or in-memory databases without swapping. Workloads that exceed this footprint will page to storage and lose throughput. The kit fills every supported slot on this platform, so further expansion requires a different motherboard or higher-density modules not validated for this board.

Questions about this item

Will the 1Rx8 ECC RDIMM modules need any firmware updates or periodic replacement after installation?

These DDR5 modules have no firmware and no moving parts; they run at 1.10 V with CL52 latency and require no scheduled replacement once seated in the GIGABYTE MZ73-LM2 slots.

What limit appears first when all four 16 GB RDIMMs run at DDR5 6400 continuously?

The registered buffer and ECC logic keep every slot stable at the rated 6400 MT/s, so the first boundary is the motherboard's maximum supported capacity rather than memory speed.

How much heat and power does the 64 GB kit draw at 1.1 V under all-day load?

Each 1Rx8 module operates at 1.10 V without a heat spreader; total kit power stays within standard DDR5 RDIMM limits and passive airflow in a server chassis is sufficient.
