ECC Registered RDIMM for QNAP TDS-16489U

This is a single 16GB DDR4 2400 CL17 ECC Registered RDIMM built for the QNAP TDS-16489U NAS. It runs at 1.2V with a 2Rx8 layout on a 288-pin form factor. The module adds error-correcting, registered memory to compatible server or workstation platforms.

Who this suits and who should look elsewhere

It fits administrators upgrading a QNAP TDS-16489U or matching the QNAP part numbers RAM-16GDR4ECT0-RD-2400 and RAM-16GDR4-RD-2400. It will not work in standard desktop computers and cannot be mixed with unbuffered memory. Buyers who need non-ECC or unbuffered modules should choose a different product.

DDR4 2400 CL17 Registered ECC specification

The decisive spec is DDR4 2400 (PC4-19200) with CL17 latency in a registered ECC RDIMM. This combination determines whether the module will post and run correctly in the target QNAP system. Verify the platform requires registered ECC before ordering.
