QNAP NAS Memory Upgrade

This OWC module adds 16GB of DDR4 2666 CL19 memory to compatible QNAP NAS models. It uses a 260-pin SODIMM form factor and runs at 1.2V without ECC or buffering. The single stick is designed for the TS-332X, TS-473, TS-673, TS-832PX and TS-832X.

Suits owners of listed QNAP units needing more RAM

Builders working with desktop DIMM slots cannot use this SODIMM format. Systems that require ECC error correction will not gain that feature from this non-ECC module. Buyers whose NAS model is not in the compatibility list should verify support before purchasing.

260-pin DDR4 SODIMM form factor decides fit

The module installs only in SO-DIMM slots wired for DDR4 signalling. It is backwards compatible with 2400MHz and 2133MHz bus speeds. A system needing 288-pin DIMMs or a different DDR generation will not accept this part.

Questions about this item

Which QNAP NAS models accept this 16GB DDR4 2666 SODIMM as a memory upgrade?

The module is validated for the TS-332X, TS-473, TS-673, TS-832PX and TS-832X. It replaces QNAP part numbers RAM-16GDR4T0-SO-2666, RAM-16GDR4K0-SO-2666 and RAM-16GDR4K1-SO-2666.

Will the 2666MHz module run stably if my NAS currently uses 2400MHz or 2133MHz memory?

Yes. The SODIMM is backwards compatible with 2400MHz and 2133MHz systems and will operate at the lower speed supported by the platform.

How can I confirm the NAS recognises the full 16GB capacity after installation?

After booting, open the QTS Control Panel, go to System > Hardware and verify that Total Memory shows the expected 16GB increase.
