Targeted NAS Upgrade

This single 32GB DDR4 2666 SODIMM is validated for QNAP TS-435XeU, TS-473A, TS-673A, TS-873A and TVS-472XT systems. It replaces the OEM part RAM-32GDR4T0-SO-2666 and adds a full 32GB in one slot for memory-hungry NAS workloads.

DDR4 SODIMM Limits

The module runs at the JEDEC-standard 2666 MT/s with CL19 latency and 1.2V operation. It is backward compatible with 2400 and 2133 MT/s buses, so it will clock down automatically if the platform requires a lower speed.

Unbuffered Non-ECC Build

The 260-pin stick uses a 2Rx8 unbuffered layout without a heat spreader, keeping the profile low for tight NAS chassis. Non-ECC operation suits the listed QNAP models, while JEDEC and RoHS compliance ensure a warranty-safe installation.

Questions about this item

Is this 32GB module the only capacity available for my QNAP TS-473A?

This specific part is a single 32GB DDR4 2666 CL19 SODIMM. OWC offers other capacities and kits separately, so check the full range if you need a different total memory size.

What does the PC4-21300 rating mean when the module is installed in a TS-873A?

The module is rated for 2666MHz operation at CL19 latency. In your TS-873A it will run at that speed or downclock automatically to 2400MHz or 2133MHz if the system requires it.

Will the 260-pin DDR4 SODIMM fit the memory slot in my TVS-472XT?

Yes, the 260-pin DDR4 SODIMM form factor matches the slots used by the TVS-472XT and the other listed QNAP models.
