OWC 8GB DDR4 2666 ECC UDIMM

This 8GB DDR4 2666 ECC unbuffered UDIMM is built for ASUSTOR AS7112RDX and AS7116RDX LOCKERSTOR NAS systems. It adds error-correcting memory capacity to supported 12-bay and 16-bay rackmount units. The module runs at 1.2V with CL19 latency and a 1Rx8 organisation.

Check DDR4 ECC UDIMM slot availability

Verify that your ASUSTOR NAS has a free 288-pin DDR4 UDIMM slot before ordering. The system must accept ECC unbuffered modules at 2666, 2400 or 2133 speeds. Confirm the current memory configuration to ensure the upgrade matches the platform requirements.

Replaces ASUSTOR AS-8GECD4-U module

This OWC module directly replaces the ASUSTOR part number AS-8GECD4-U with a JEDEC-standard 8GB DDR4 2666 ECC UDIMM. The upgrade is worth it when the NAS shows memory pressure during multi-user file access or virtualisation workloads. Backward compatibility with 2400 and 2133 speeds eases mixed-population installs.

Questions about this item

What comes with the OWC 8GB DDR4 2666 ECC UDIMM module and what else is needed?

The box contains one 8GB DDR4 2666 CL19 1Rx8 1.2V ECC unbuffered UDIMM. No extra parts are required; the module fits directly into the ASUSTOR AS7112RDX or AS7116RDX memory slots.

Which capacity and speed version should I choose for the ASUSTOR LOCKERSTOR 12R or 16R PRO?

This specific module is the 8GB DDR4 2666 (PC4-21300) CL19 1Rx8 ECC UDIMM. It matches the ASUSTOR part number AS-8GECD4-U and is the correct upgrade for those NAS models.

What does the 2666 MHz speed mean once the module is installed in the ASUSTOR NAS?

The module runs at 2666 MHz (PC4-21300) with CL19 latency at 1.2V. It is backward compatible with 2133 MHz and 2400 MHz operation if the system requires a lower speed.
