Exact-match DDR5 upgrade

This 768 GB kit contains twelve 64 GB DDR5 RDIMMs specified at 4800 MT/s, CL40, 1.1 V, 2Rx4 registered ECC. It is built for the GIGABYTE MZ73-LM2 motherboard and matches the rank, voltage and timing the board's memory controller expects.

Capacity and headroom

Fully populated, the kit delivers 768 GB of registered ECC memory, allowing large virtual-machine fleets, in-memory databases and heavy analytics workloads to run without swapping. The registered architecture keeps every slot stable at full capacity, while ECC corrects single-bit errors on the fly. Workloads that exceed 768 GB or require faster transfer rates will need a platform that supports higher densities or speeds.

What the kit changes

The bundle supplies a complete twelve-module population so no slots remain empty and no mixed-rank configurations are introduced. Registered buffering offloads the memory controller, and ECC prevents silent data corruption from reaching production. No heat spreaders, software utilities or additional accessories are included.
