32GB DDR4 ECC kit for ASUSTOR NAS

This OWC kit supplies 32GB of DDR4 2666 memory in two 16GB unbuffered UDIMMs with ECC. It is built for ASUSTOR AS7112RDX and AS7116RDX Lockerstor units that require 288-pin DDR4 modules. The CL19 timing and 1.2V operation match the platform specifications.

Who benefits and who should pass

Administrators expanding NAS memory for virtualisation, ZFS caching or multi-user workloads will gain capacity and error correction. Systems that need registered DIMMs, speeds above 2666 MT/s, or non-ECC modules cannot use this kit.

The deciding specification

The modules are unbuffered ECC UDIMMs at DDR4 2666 with CL19 latency. If the target NAS calls for registered memory or a different speed grade, this kit will not be compatible.

Questions about this item

Which ASUSTOR NAS models does this 32GB DDR4 2666 ECC UDIMM kit support?

The kit is validated for the ASUSTOR AS7112RDX and AS7116RDX LOCKERSTOR 12R and 16R PRO systems.

Will these 2666MHz modules run in a bay that currently uses 2133MHz or 2400MHz memory?

Yes, the modules are backward compatible with 2133MHz and 2400MHz speeds and will operate at the lower frequency.

How can I confirm the system recognises the full 32GB capacity after installation?

Check the NAS management interface or BIOS memory information; it should report 32GB total across the two 16GB modules.
