QNAP TVS-h874T memory upgrade

This 16 GB DDR4 SODIMM is built for the QNAP TVS-h874T SMB NAS. It targets administrators who need to expand system memory for virtualization, container workloads or heavy file serving. The module is validated for that platform and ships as a single 16 GB stick.

260-pin DDR4 2666 unbuffered SODIMM

The stick plugs directly into the NAS DDR4 SO-DIMM slots with no extra hardware. It runs at 1.2 V and uses a standard 2Rx8 unbuffered layout, so the system recognises it without BIOS changes. Adding it frees the existing slots for further expansion if the chassis supports more modules.

CL19 latency under sustained load

Rated at DDR4 2666 with CL19 timings, the module maintains stable throughput during long backup windows or continuous database access. Major OEM Samsung, Micron or Hynix ICs are stress tested under load to prevent errors that can corrupt NAS volumes over time.

Questions about this item

Does the CL19 latency limit sustained throughput on the QNAP TVS-h874T?

CL19 is the rated CAS latency at 2666 MT/s; the module runs at 1.2 V without a heat spreader, so latency remains constant under load.

How much heat or noise does the 1.2 V SODIMM add during all-day NAS operation?

The unbuffered DDR4 module draws 1.2 V and has no heat spreader or fan, so it adds negligible heat and zero acoustic noise inside the chassis.

What must the QNAP TVS-h874T already have for this 260-pin DDR4 SODIMM to work?

The NAS needs a free 260-pin DDR4 SODIMM slot that accepts non-ECC unbuffered memory at 2666 MT/s.
