NEMIX RAM 128GB (2x64GB) DDR5 5600 CL46 ECC RDIMM for GIGABYTE MZ73-LM0 memory upgrade

Exact-match 128 GB kit for GIGABYTE MZ73-LM0

This 128 GB kit consists of two 64 GB DDR5 5600 CL46 registered ECC RDIMMs built to the precise rank, voltage and timing the GIGABYTE MZ73-LM0 memory controller expects. It is intended for server administrators who need the board to recognise full capacity at rated speed without manual tuning. Builders using desktop boards or unbuffered memory will find the registered design incompatible.

DDR5 5600 registered ECC constraints

The modules operate at 1.1 V with a CAS latency of 46 and a 2Rx4 organisation, delivering PC5-44800 bandwidth only when the platform supports registered DIMMs and ECC error correction. Population rules, maximum per-slot capacity and supported ranks are defined by the motherboard firmware, so exceeding the documented limits will prevent boot or reduce speed. Systems that require unbuffered UDIMMs or non-ECC memory cannot use this kit.

Build and daily handling

Each stick uses a standard 288-pin RDIMM form factor without a heat spreader, relying on chassis airflow for cooling. The registered buffer reduces electrical load on the memory controller, allowing all slots to be populated at full capacity while ECC corrects single-bit errors on the fly. Installation follows the board's prescribed slot order; no additional cables or software configuration are needed beyond firmware recognition.
