Server-grade DDR4 ECC Registered memory

This 32 GB kit contains two 16 GB modules built to the DDR4 2666 standard. Registered operation and on-die ECC protect data integrity in multi-socket servers and workstations that require registered DIMMs.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller, allowing stable operation across all populated slots during continuous workloads. ECC correction handles single-bit errors without halting the system, keeping throughput consistent over long runs.

Installation notes

Modules use the standard 288-pin DDR4 form factor and install like any registered DIMM; ensure the platform explicitly supports registered ECC memory. Mixing registered with unbuffered DIMMs or populating slots in an unsupported order will prevent the system from posting.

Questions about this item

How much power does the DDR4 2666 registered ECC kit draw under continuous server load?

DDR4 registered modules typically operate at 1.2 V; the 2Rx4 organisation and ECC logic add only a small overhead compared with unbuffered DIMMs, so sustained draw stays modest in a 288-pin slot.

What motherboard feature must already be present for the 288-pin DDR4 2666 registered DIMMs to function?

The board needs DDR4 slots that support registered ECC memory and a memory controller able to address 2Rx4 modules at 2666 MT/s.

Will the 2Rx4 registered sticks work in an older DDR4 platform that only accepts unbuffered memory?

No — registered DIMMs require a chipset and BIOS that explicitly support registered operation; they will not post in a consumer board limited to unbuffered modules.
