NEMIX RAM DDR5 4800 ECC Registered RDIMM 256GB (4x64GB) CL40 1.1V 2Rx4 288-pin memory upgrade

Server-grade DDR5 memory kit

This NEMIX RAM kit supplies 256 GB of DDR5-4800 registered ECC memory in four 64 GB modules. It is built for the GIGABYTE MZ73-LM2 motherboard and matches the exact rank, voltage and timing the board's memory controller expects. The 2Rx4 RDIMM format ensures full-capacity recognition when all slots are populated.

Thermals noise and power draw

Modules run at the standard DDR5 voltage of 1.1 V and carry no heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping keep power draw predictable under sustained server workloads. Silent operation is inherent with no moving parts on the DIMMs themselves.

Upgrade path and fitment

The kit replaces partial or mismatched memory configurations that limit total capacity or prevent the board from running at its rated 4800 MT/s. It is not suited for systems that require unbuffered UDIMMs or SODIMMs, nor for boards that cannot accept 2Rx4 registered modules. Verify the motherboard manual for approved population order before installing.
