  • 128 GB capacity with two 64 GB modules for high-density server workloads
  • DDR5 5600 speed rated at PC5-44800 for fast data throughput
  • ECC and registered design corrects single-bit errors and stabilises fully populated slots
  • CL46 latency at 1.1 V matches the board's memory-controller specifications
  • 288-pin RDIMM form factor verified for the Gigabyte MZ73-LM1 motherboard

Purpose-Built Capacity

This 128GB kit delivers two 64GB DDR5 RDIMMs rated at 5600MHz PC5-44800 with CL46 latency and 1.10V operation. Registered ECC architecture meets the GIGABYTE MZ73-LM1 motherboard's exact population rules so every slot is recognised at full capacity without downclocking.

Registered ECC Advantage

Unlike unbuffered UDIMMs or non-ECC modules, the 2Rx4 registered design offloads the memory controller and corrects single-bit errors on the fly, preventing silent data corruption during continuous server workloads. The precise rank, voltage and timing match what the board expects, eliminating compatibility guesswork.

Sustained Load Behaviour

Under prolonged utilisation the registered buffers maintain signal integrity across all populated channels while ECC scrubs errors in real time, keeping throughput stable rather than throttling. Lifetime replacement coverage and US-based technical support back the deployment for its operational lifespan.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor match the GIGABYTE MZ73-LM1 motherboard slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the GIGABYTE MZ73-LM1 requires; it is not a UDIMM or SODIMM.

What is the correct population order for the two 64 GB modules on the GIGABYTE MZ73-LM1?

Consult the motherboard manual for the approved DIMM population sequence; the kit is spec-matched to the board's memory-population rules.

Will the Samsung, Micron or Hynix DRAM chips used in these modules require any firmware updates later?

No firmware updates are needed for the DRAM chips; the modules run at the rated DDR5 5600 CL46 1.1 V once installed.
