System-Specific DDR4 Upgrade

This 16 GB kit contains two 8 GB DDR4 2400 SODIMM modules built for QNAP TS-473 and TS-673 series NAS units. It targets owners of those models who need more memory for virtualization, caching or heavy multi-user workloads. The CL17 unbuffered design matches the factory specification for the listed servers.

260-Pin SO-DIMM Form Factor

Each stick uses the standard 260-pin DDR4 SO-DIMM layout and runs at 1.2 V, so it drops straight into the four memory sockets on the compatible QNAP boards. No heat spreader is fitted, keeping the module height low for tight NAS chassis. Installing the pair in matched slots lets the controller run in dual-channel mode.

16 GB Kit Within 64 GB Limit

The two modules give 16 GB total; the platform supports up to 64 GB across its four slots, leaving room for a second identical kit later. Non-ECC operation means the memory suits the supported TS-473 and TS-673 configurations but will not provide error correction for critical data integrity needs. Mixing with slower modules forces the whole system down to the lowest speed.

Questions about this item

Will the 2400 MHz speed hold steady during long NAS workloads?

The modules run at DDR4 2400 (PC4 19200) with CL17 timing and 1.2 V voltage, so the rated speed is maintained under sustained use.

How much heat or noise do the sticks add when the NAS runs 24/7?

There is no heat spreader on these unbuffered SODIMMs, so they rely on the chassis airflow and add no fan noise of their own.

Which QNAP models must I already own for this kit to work?

The kit is validated for TS-473, TS-473-4G, TS-473-8G, TS-673, TS-673-4G and TS-673-8G NAS servers.
