  • 128 GB total capacity from four 32 GB modules
  • DDR5-4800 speed with CL40 latency for rated server performance
  • ECC and registered design corrects errors and stabilises fully populated slots
  • 1 V operation matches the platform's memory controller specification
  • 288-pin RDIMM form factor verified for the Gigabyte MZ73-LM1 motherboard

Capacity and purpose

This 128 GB kit contains four 32 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.1 V operation. Registered ECC buffering makes it suitable for servers and workstations that require error correction and full-slot population.

Form factor and daily implications

The 288-pin RDIMM modules carry no heat spreader, so they fit standard server DIMM slots without clearance concerns. Registered architecture reduces electrical load on the memory controller, allowing all four slots to run at rated speed, while on-die ECC corrects single-bit errors before they affect data integrity.

Upgrade context and fit

The kit is validated for the GIGABYTE MZ73-LM1 motherboard and replaces any lower-capacity or non-ECC DDR5 RDIMM set that cannot reach 128 GB in a four-slot configuration. The jump is worthwhile when the platform's memory population rules demand registered 2Rx8 modules at this exact voltage and timing to achieve maximum supported capacity.

Questions about this item

Does DDR5 4800 PC5-38400 run at its rated speed on the GIGABYTE MZ73-LM1?

Yes, the kit is spec-matched to the board's DDR5 4800 controller so all four modules operate at 4800 MT/s with CL40 timing.

Will these 288-pin RDIMMs fit the MZ73-LM1 DIMM slots?

The motherboard requires 288-pin Registered RDIMMs; this kit uses exactly that form factor and the 2Rx8 rank layout the board's population rules expect.

What is the correct installation order for the four modules on this board?

Consult the MZ73-LM1 manual for the approved DIMM population sequence; fully populated Registered ECC kits must follow the vendor's slot order to initialise at full capacity.
