Compatible QNAP NAS upgrade

This 16 GB DDR4 SODIMM module is built for QNAP TVS-473e and TVS-673 series NAS devices. It delivers a straightforward capacity increase for users who need more memory for virtualisation or heavy multitasking. The stick arrives as a single 16 GB unit ready to install.

Non-ECC unbuffered specification

The module runs at DDR4 2400 (PC4 19200) with CL17 17-17-17 timings at 1.2 V. It uses a 260-pin SO-DIMM form factor with 2Rx8 organisation and no heat spreader. Systems requiring ECC or registered memory cannot use this part.

Simple slot insertion

Installation only requires opening the NAS chassis and seating the module in an empty SODIMM slot. The supplier notes that mixing modules forces all memory to run at the slowest installed speed. Buyers needing ECC support or capacities beyond 64 GB must choose a different product.

Questions about this item

How does the 2400 MHz speed affect performance in a QNAP TVS-473e or TVS-673 NAS?

The module runs at DDR4-2400 with CL17 timing. If the NAS CPU or existing memory runs slower, the system will downclock all modules to the lowest common speed.

What does the 260-pin SO-DIMM form factor mean for installation?

It uses the standard 260-pin DDR4 SO-DIMM slot. The stick is unbuffered, non-ECC and 1.2 V, so it fits the memory sockets on the listed QNAP models without adapters.

Will the 16 GB stick physically fit the TVS-473e and TVS-673 chassis?

Yes. It is a standard-height SO-DIMM without a heat spreader, so it clears the motherboard sockets in the TVS-473e and TVS-673 series NAS units.
