Capacity and fit

This NEMIX RAM kit delivers 256GB of DDR5 memory in two 128GB registered DIMMs built for the GIGABYTE MZ73-LM1 motherboard. It targets administrators who need the exact rank, voltage and timing the board expects so every slot is recognised at full speed.

Throughput and limits

The modules run at 5600MHz (PC5-44800) with CL46 latency at 1.10V, using a 2Rx4 organisation that lets the memory controller address the full density across both sticks. Workloads that exceed 256GB or require lower latency than CL46 will need a different configuration.

Build and daily use

Each stick is a 288-pin RDIMM without a heat spreader, relying on server chassis airflow for cooling. The registered buffer reduces electrical load on the controller when all slots are populated, while on-die ECC corrects single-bit errors before they affect data. Buyers who need unbuffered UDIMMs, SODIMMs or modules with integrated heat spreaders should look elsewhere.

Questions about this item

Will these 288-pin DDR5 5600 CL46 modules run at full speed if I keep my existing 128GB RDIMMs in the other slots?

The kit is validated for the GIGABYTE MZ73-LM1 at DDR5 5600 (PC5-44800) with CL46 timing and 1.1V. Mixing ranks or capacities can force the controller to downclock; consult the motherboard manual for the approved population order before adding these 2Rx4 modules alongside other DIMMs.

How can I confirm the 256GB kit is operating at 5600 MT/s with ECC active after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 5600 MT/s, the timings show CL46, and ECC is reported as enabled. The registered RDIMM design and on-die ECC will also appear in the system health or IPMI logs once the OS loads.

Does the package include only the two 128GB RDIMMs or are any cables or brackets supplied?

The box contains the 256GB kit — two 128GB 288-pin DDR5 5600 CL46 1.1V ECC Registered RDIMMs. No cables, brackets, or additional accessories are included.
