OWC 16GB DDR4 2666 CL19 2Rx8 260-pin 1.2V Non-ECC SODIMM memory upgrade

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.
