16GB DDR4-2666 ECC Registered Module

This 288-pin DDR4 SDRAM module delivers 16GB capacity at 2666MHz with CL15 latency and 1.20V operation. It uses a 1Rx4 registered design with ECC for data integrity in server environments.

Suits Lenovo systems needing PC4-21300 registered

Administrators expanding virtualisation capacity or eliminating paging in compatible Lenovo servers will benefit. Builders requiring unbuffered UDIMMs, higher frequencies or larger single-module densities should look elsewhere.

Third-party major-brand chips maintain OEM service

Modules ship with Samsung, SK Hynix or Micron components that meet or exceed Lenovo specifications. The lifetime warranty covers the hardware itself, while OEM compatibility preserves existing support agreements without additional software.

Questions about this item

Does this 16GB DDR4-2666 ECC Registered RDIMM need a server motherboard that supports registered memory and ECC?

Yes, this 288-pin DDR4 module requires a server platform that accepts registered ECC RDIMMs at 1.2V; standard desktop boards without ECC and registered support will not work.

Can I add this CL15 1Rx4 module alongside existing DDR4-2666 registered ECC DIMMs in my Lenovo server?

It will operate at the lowest common speed and timings across all populated slots, so matching rank, voltage and CAS latency helps maintain full DDR4-2666 performance.

How do I confirm the module is running at PC4-21300 with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report 2666 MT/s, 1.2V, registered ECC and the correct 16GB capacity per DIMM.
