16GB DDR4 2666MHz ECC Registered RDIMM

This module is a 16GB DDR4 2666MHz CL19 registered DIMM with ECC and a 1Rx4 organisation. It is built for servers and workstations that require registered memory with error correction for data integrity.

288-pin RDIMM installation and compatibility

The 288-pin RDIMM fits standard DDR4 server slots and operates at the standard 1.20V voltage. Because registered memory places a load on the memory controller, you must verify that your platform supports registered ECC modules and the specific 1Rx4 rank configuration before purchasing.

Suited for Supermicro-certified server upgrades

This memory suits administrators upgrading or repairing Supermicro-certified systems that specify the MEM-DR416LA-ER26 part. It is not suitable for desktop boards that accept only unbuffered non-ECC DIMMs or for platforms that require a different rank structure or voltage.

Questions about this item

How can I verify the module is running at 2666 MHz with CL19 after installation?

Check the memory speed and CAS latency in your server BIOS or with a tool such as dmidecode; they should show 2666 MT/s and CL19 at 1.20 V.

What comes in the package and what must be sourced separately?

The box contains one 16 GB Samsung RDIMM (M393A2K40CB2-CTD); no extra cables, brackets or cooling are included or required.

Which capacity or rank option should I pick for a Supermicro system needing registered ECC?

Choose this 16 GB 1Rx4 registered ECC module (MEM-DR416LA-ER26) when your board calls for a single-rank DDR4 RDIMM at 2666 MHz.
