System-specific DDR5 ECC kit

This 32 GB kit contains two 16 GB DDR5 5600 modules built for the ASRock Rack W880D4U-2L2T motherboard. Each unbuffered UDIMM operates at 1.1 V with CL46 latency and 1Rx8 organisation. The ECC capability helps maintain data integrity in server and workstation workloads.

Sustained-load behaviour

Running at the rated 5600 MT/s speed, the modules deliver consistent throughput for memory-intensive tasks such as virtualisation, compilation or database caching. The 1Rx8 layout keeps signal loading light on the memory controller, supporting stable operation during extended multi-threaded workloads without downclocking.

Thermals and power draw

Operating at the standard 1.1 V DDR5 voltage, power consumption remains modest under typical server loads. The modules ship without a heat spreader, relying on chassis airflow for cooling; in a properly ventilated rack or workstation case temperatures stay within normal DDR5 limits and acoustic impact is negligible.

Questions about this item

How much power does the 1.1 V DDR5 5600 kit draw when the system runs continuously?

The modules operate at 1.1 V, which is the standard DDR5 voltage, keeping power draw low during all-day workloads.

What motherboard slot and memory controller features are required for this 2 x 16 GB kit to function?

It needs a 288-pin DDR5 UDIMM slot and a CPU memory controller that supports ECC unbuffered DDR5 at 5600 MT/s.

Can this 5600 CL46 ECC UDIMM kit share channels with slower DDR5 modules I already own?

Mixing speeds or latencies forces all modules to run at the lowest common rate, so the 5600 kit would downclock to match the older DDR5 sticks.
