Server DDR5-5600 ECC module for registered platforms

This 16 GB DDR5 DIMM runs at 5600 MHz with CL46 timings and 1.10 V operation. It includes ECC and registered signal processing for data integrity in server and workstation motherboards that require registered memory. The single-rank 1Rx8 organisation fits 288-pin slots without a heat spreader.

Sustained throughput at rated speed

At 5600 MHz the module delivers PC5-44800 bandwidth continuously, avoiding the throttling that can occur with unbuffered consumer modules under prolonged load. Registered buffering keeps command and address signals stable during extended compute or virtualisation workloads. ECC corrects single-bit errors in real time so long-running jobs stay accurate.

Thermals and power at standard voltage

Operating at 1.10 V keeps power draw low and reduces heat output in densely populated DIMM banks. The absence of a heat spreader means airflow from chassis fans passes directly over the DRAM packages. Registered signalling adds minimal latency while maintaining signal quality across full memory channels.

Questions about this item

How much power does the 1.10 V DDR5-5600 module draw under sustained server loads?

At the rated 1.10 V the module operates at standard DDR5 voltage; registered buffering and single-rank layout keep per-DIMM power within normal DDR5-5600 limits for continuous operation.

Which motherboard features are required to run this 288-pin registered ECC DIMM?

A server-class motherboard with DDR5 RDIMM slots, registered-buffer support and ECC capability is required; the 288-pin form factor will not fit consumer UDIMM sockets.

Will this CL46 5600 MHz stick down-clock reliably in a DDR5-4800 registered platform?

Yes, JEDEC DDR5 modules negotiate speed at boot; the 5600 MT/s part will run at the highest common speed the platform supports while keeping registered ECC operation.
