Compatible QNAP NAS Upgrade

This 4GB DDR4 SO-DIMM is built for QNAP TS-473 and TS-673 series NAS servers. It targets owners who need a straightforward capacity increase for multi-tasking or virtualization workloads. The module arrives as a single 4GB stick validated for those specific models.

Standard SO-DIMM Build

The stick uses a 260-pin unbuffered layout running at 1.2V without a heat spreader. Major-brand chips are arranged in a 2Rx8 configuration, so it fits the standard SODIMM slots inside the compatible QNAP units. Installation follows the usual laptop-memory procedure with no extra cables or brackets required.

Low-Power Operation

CL17 timing at 2400 MHz keeps latency tight while the 1.2V supply limits heat output inside the sealed NAS chassis. Because the module is non-ECC and unbuffered, it runs quietly with no active cooling needed. All installed memory will operate at the slowest module speed, so mixing with faster sticks offers no gain.

商品問答

Does the DDR4 2400 interface limit the speed in a QNAP TS-473 or TS-673?

The module runs at 2400 MHz PC4 19200 with CL17 timing at 1.2 V, and the NAS will operate all installed memory at the slowest module or CPU capability.

Will this 260-pin SO-DIMM fit the memory slots in the TS-473 and TS-673 models?

Yes, it is a 260-pin DDR4 SO-DIMM without a heat spreader, matching the SODIMM sockets used in the TS-473, TS-473-4G, TS-473-8G, TS-673, TS-673-4G and TS-673-8G.

What is the correct installation method and the step users often miss?

Align the notch on the module with the key in the slot, press firmly until the side clips lock automatically, then confirm the new capacity in the QNAP firmware.
