32GB DDR4 ECC UDIMM for QNAP NAS

This 32GB DDR4 2666 CL19 ECC unbuffered UDIMM is built for QNAP TNS-h1083X, TS-1283XU-RP, TS-1683XU-RP, TS-2483XU-RP and TS-883XU systems. It adds error-correcting capacity to NAS appliances that demand data integrity. The module is not suited for platforms that require registered DIMMs or non-ECC memory.

Tool-less slot installation

Installation is a straightforward DIY task: align the notch on the 288-pin edge connector and press until the latches click. The stick runs at 1.2V and carries no heat spreader, so it fits tight NAS chassis without clearance issues. Backward compatibility with 2133MHz and 2400MHz buses means it will down-clock automatically if the system demands it.

Single 32GB rank for high-density expansion

The 2Rx8 organisation delivers 32GB in one slot, leaving remaining DIMM sockets free for future growth. It comfortably handles multi-user file serving, virtualisation workloads and large-volume backup jobs that benefit from ECC protection. Capacity runs out when the NAS reaches its maximum supported memory limit or when an application requires registered modules instead of unbuffered ones.

Preguntas sobre este artículo

How do I verify the 32GB DDR4 2666 CL19 2Rx8 module is detected and running at 2666MHz with ECC active after installation?

Enter the QNAP BIOS or the NAS firmware dashboard; the memory page should show a single 32GB 288-pin DDR4 ECC UDIMM at 2666MHz (PC4-21300), CL19, 1.2V, 2Rx8, unbuffered, with ECC status reported as enabled.

What ships with the OWC 32GB DDR4 2666 ECC UDIMM and what, if anything, must be purchased separately?

The box contains one 32GB DDR4 2666 CL19 2Rx8 288-pin 1.2V ECC unbuffered UDIMM; no cables, brackets or additional parts are included, and nothing extra is required to install it in a compatible QNAP NAS.

Which capacity and speed version should I choose for a QNAP TS-1283XU-RP that currently runs 2133MHz modules?

Select this 32GB DDR4 2666 (PC4-21300) CL19 2Rx8 ECC UDIMM; it is backward-compatible with 2133MHz and 2400MHz operation and replaces QNAP part RAM-32GDR4ECS0-UD-2666.
