16 GB DDR4 ECC UDIMM for servers

This 16 GB DDR4 2666 module adds ECC unbuffered memory to compatible servers and workstations. It runs at 1.2 V with CL19 latency and a 2Rx8 dual-rank layout on a 288-pin DIMM. The PC4-21300 rating matches the DDR4 2666 specification.

Suits ECC UDIMM platforms only

The module is built for systems that explicitly support DDR4 ECC unbuffered DIMMs. It will not work in desktop or laptop computers that require non-ECC or buffered memory. Buyers who need non-ECC memory for consumer boards should look elsewhere.

Tested modules with lifetime warranty

Every unit undergoes quality assurance testing before shipment to verify reliable operation. A lifetime warranty covers the module, and US-based technical support is available for installation guidance and compatibility questions.

Preguntas sobre este artículo

Do I need a motherboard that supports DDR4 ECC UDIMM modules for this 16 GB 2666 MHz stick to work?

Yes, the module is a 288‑pin DDR4 ECC UDIMM running at 2666 MHz and requires a server or workstation board that accepts DDR4 ECC unbuffered memory.

Can I mix this dual‑rank 2Rx8 CL19 module with existing single‑rank DDR4 2666 ECC UDIMMs in the same system?

Mixing ranks is possible on many platforms, but the memory controller will run all modules at the lowest common speed and latency; check your system manual for supported rank combinations.

How can I confirm the module is running at 2666 MHz with ECC active after installation?

Enter the BIOS or use an OS tool such as dmidecode or CPU‑Z; both will show the configured speed of 2666 MHz and report ECC as enabled for the 16 GB module.
