Capacity and purpose

This NEMIX RAM module provides 64GB of DDR5 ECC unbuffered memory in a single 288-pin UDIMM. It is built for the ASRock Rack W880D4U-2L2T motherboard and suits servers or workstations that require error-correcting code protection for data integrity.

Sustained-load behaviour

The module operates at 5600MHz with a CL46 latency and 2Rx8 organisation. Under continuous workloads the ECC function detects and corrects single-bit errors without halting the system, maintaining stable throughput for virtualization, database or scientific tasks.

Thermals and power

Running at 1.1V the DIMM draws minimal power and has no heat spreader, relying on chassis airflow for cooling. The low voltage and unbuffered design keep heat output modest, so acoustic impact is negligible in a properly ventilated server enclosure.

Questions about this item

How much power does the 64GB DDR5 5600 CL46 ECC UDIMM draw when running continuously at 1.1V?

The module operates at 1.10V, the standard DDR5 voltage, so power draw scales with the 5600 MT/s data rate and 2Rx8 organisation rather than exceeding the baseline for this capacity.

What motherboard slot and firmware support are required to install this 288-pin DDR5 ECC UDIMM?

The stick fits a standard 288-pin DDR5 UDIMM slot and is validated for the ASRock Rack W880D4U-2L2T; the platform must enable ECC in BIOS for error correction to function.

Can I mix this 2Rx8 CL46 DDR5 ECC module with existing 1Rx8 or slower DDR5 ECC DIMMs in the same server?

Mixing ranks or CAS latencies is possible on the W880D4U-2L2T, but the memory controller will run all populated slots at the lowest common speed and highest latency.
