16 GB DDR4-2666 Registered ECC Module

This 16 GB DDR4-2666 registered ECC DIMM is built for HPE server platforms that require 288-pin DDR4 SDRAM at PC4-21300 speed. It operates at 1.20 V with a 1Rx4 organisation and uses major-brand memory chips from Samsung, SK Hynix or Micron. The module is validated for full compatibility and designed to maintain the original factory warranty on supported systems.

Suited for HPE server upgrades needing ECC integrity

It fits administrators expanding memory in compatible HPE servers where registered ECC DDR4-2666 is specified. The single-rank 1Rx4 layout works within the platform’s qualified configuration. Builders needing non-ECC, unbuffered, higher-speed or lower-voltage memory should look elsewhere because this module is fixed at registered ECC DDR4-2666 1.20 V.

16 GB capacity per DIMM with DDR4-2666 bandwidth

Each stick delivers 16 GB of addressable memory and runs at the PC4-21300 data rate, providing headroom for virtualisation workloads and large dataset caching. Capacity scales by populating additional qualified slots up to the server’s maximum supported memory. The module reaches its limit when the platform’s total memory ceiling or rank-per-channel limit is reached.

Questions about this item

Do I need a server that accepts 288-pin DDR4 registered ECC modules to use this 16GB stick?

Yes — this module is a 288-pin DDR4 SDRAM with registered ECC and 1.20 V operation, so the host system must support DDR4 registered memory.

Can I mix this 1Rx4 2666 MHz module with existing 2Rx4 or slower DDR4 DIMMs in the same server?

Mixing ranks and speeds is possible on many platforms, but the memory controller will run all DIMMs at the lowest common speed and may apply specific population rules; check the server manual for supported configurations.

How can I verify the module is running at PC4-21300 2666 MHz with ECC active after installation?

Enter the BIOS/UEFI or use a tool such as dmidecode to confirm the reported speed is 2666 MT/s, the data width shows ECC, and no memory errors are logged during POST.
