  • 128 GB total capacity from four 32 GB modules for dense server workloads
  • DDR5 6400 speed with CL52 latency delivers rated throughput on the GIGABYTE MZ73-LM1
  • Registered ECC architecture corrects single-bit errors and keeps every slot stable at full population
  • 10 V operation matches the platform's memory-controller specification exactly
  • 288-pin RDIMM form factor fits the board's required DIMM slots without adapters

128GB DDR5-6400 ECC RDIMM Kit

This 128GB kit contains four 32GB DDR5-6400 registered ECC modules built for the GIGABYTE MZ73-LM1 motherboard. Each module runs at 1.1V with CL52 latency and a 2Rx8 organisation. The registered design and ECC function are required for stable operation in this server platform.

Upgrade from smaller or slower DDR5 kits

Replacing a lower-capacity or slower DDR5 kit with this matched 4x32GB set lets the board run fully populated at the rated 6400 MT/s speed. The jump is worth it when your workload needs the full 128GB capacity and the registered buffering that keeps every slot stable at that density.

Limits of the DDR5 RDIMM interface

The DDR5 RDIMM standard used here requires a motherboard that supports registered ECC modules and the specific population rules of the MZ73-LM1. Boards that accept only unbuffered UDIMMs or non-ECC memory cannot use this kit. Maximum capacity and speed are ultimately defined by the platform's memory controller and BIOS.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the GIGABYTE MZ73-LM1 motherboard?

Yes, the kit is verified for the GIGABYTE MZ73-LM1 and uses the 288-pin Registered DIMM form factor that board requires.

What population order should I follow when installing all four 32GB modules?

Consult the GIGABYTE MZ73-LM1 manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first for full 128GB operation.

Do the Samsung, Micron or Hynix chips on these modules require any periodic maintenance?

No, the DRAM chips are solid-state components with no moving parts and need no scheduled maintenance or replacement during normal server operation.
