QNAP NAS memory upgrade

This 16GB DDR4 SODIMM module is built for QNAP TS-873, TS-932PX, TS-932X, TVS-473 and TVS-473e systems. It delivers a straightforward capacity increase for multi-user file serving, virtualization hosts or container workloads. The single-module design lets you populate a free slot without removing existing memory. Installers needing ECC or registered DIMMs should look elsewhere.

Sustained throughput at 2666 MT/s

Rated at PC4-21300 with CL19 latency, the module maintains its JEDEC speed during long backup windows, RAID rebuilds or database jobs. Unbuffered operation keeps latency predictable for latency-sensitive NAS services. Backward compatibility with 2400 and 2133 MT/s buses means it will clock down safely if the platform requires it. Builds that demand higher frequencies or tighter timings are not addressed by this part.

Low-profile 260-pin stick without heat spreader

The bare green PCB fits tight drive-bay cages and shallow CPU coolers found in compact NAS chassis. Gold-edge contacts meet 100% JEDEC and ROHS compliance for warranty-safe upgrades. Installation is tool-free and typically completes in minutes. Systems requiring taller heat-spreader modules or registered pin-outs cannot use this module.

Questions sur cet article

How much power does the 1.2 V DDR4 2666 module draw during continuous NAS operation?

The module runs at the standard 1.2 V DDR4 voltage, so power draw stays within JEDEC limits for 2666 MHz SODIMMs during all-day use.

Which QNAP models must I already own for this 260-pin SODIMM to be compatible?

This upgrade is validated for QNAP TS-873, TS-932PX, TS-932X, TVS-473 and TVS-473e systems.

Will the CL19 2666 MHz stick run stably alongside existing 2400 MHz or 2133 MHz modules?

Yes, the module is backwards compatible with 2400 MHz and 2133 MHz speeds, so it will down-clock to match older memory.
