Designed for QNAP TVS-873/e NAS

This 32GB kit contains two 16GB DDR4 2400 SO-DIMM modules built for QNAP TVS-873/e series NAS units. It fits the 260-pin slots in models such as the TVS-873-16G, TVS-873-64G, TVS-873-8G, TVS-873e-4G and TVS-873e-8G. The unbuffered, non-ECC design matches the memory architecture these systems expect.

Matched pair simplifies installation

The two sticks are sold as a matched pair so they share identical timings of 17-17-17 at CL17. Installing them together lets the NAS run in dual-channel mode without the speed penalty that mixed modules can cause. Each module operates at 1.2V and uses major-brand chips on a standard 260-pin PCB without a heat spreader.

Scales to the platform 64GB limit

Four SO-DIMM sockets are available and the platform maximum is 64GB, so this 32GB kit leaves two free slots for a future matched pair. It will not suit buyers who need ECC error correction or registered modules, and it cannot exceed the 64GB ceiling imposed by the NAS hardware.

Questions about this item

Will the 2Rx8 unbuffered DDR4 SODIMMs need any firmware updates or periodic reseating after installation?

No firmware updates or scheduled reseating are required; the 2Rx8 unbuffered DDR4 modules install directly into the 260-pin slots and operate at the rated 2400 MHz CL17 1.2 V without further intervention.

What is the maximum total memory the QNAP TVS-873/e can accept with these 16 GB modules?

The platform supports up to 64 GB across its four sockets, so two 16 GB sticks bring the system to 32 GB and leave two slots free for a future matched pair to reach the 64 GB limit.

How much heat and power do the two 16 GB DDR4 2400 CL17 sticks draw when the NAS runs continuously?

Each module runs at 1.2 V without a heat spreader; total power draw remains low and typical chassis airflow is sufficient for all-day operation in the TVS-873/e.
