Quick answer

The TS-473A takes DDR4 ECC or non-ECC SO-DIMM memory in two slots, to a limit of 64GB. It ships with 8GB fitted. Reaching 64GB means two 32GB modules, and QNAP requires the pair to be identical.

QNAP's memory rules for the TS-473A

ECC modules are supported; with two modules QNAP requires an identical pair, and says to use QNAP memory modules.

ECC modules are supported on the TS-473A, and non-ECC modules also work. To have error correction, every module fitted has to be ECC.

What else fits the TS-473A

DDR4 ECC or non-ECC SO-DIMM modules up to 32GB, by price

Modules of the type and size the TS-473A takes, no larger than 32GB each. A type and size filter: QNAP asks for its own modules, and a module here is not one QNAP has tested unless its listing says so.
