8GB ECC Registered DDR4 for QNAP NAS

This OWC module is an 8GB DDR4 3200 PC4-25600 CL22 1Rx8 288-pin 1.2V ECC Registered RDIMM designed as a direct upgrade for specific QNAP systems. It targets administrators who need error-correcting registered memory for the listed workstation and server platforms.

Verify registered ECC requirement

Before ordering, confirm your QNAP unit requires registered ECC RDIMMs and cannot accept unbuffered memory, as the two types cannot be mixed. Check the compatible model list — TDS-h2489FU, TVS-h474, TVS-h674, TVS-h874 and TS-1655 — and ensure a free 288-pin DDR4 slot exists.

Fits listed QNAP servers.

The module plugs into a standard 288-pin DDR4 socket and operates at 1.2V without a heat spreader, leaving adjacent slots clear. It serves as a replacement for QNAP part number RAM-8GDR4ECT0-RD-3200, extending memory capacity on supported NAS appliances.
