QNAP's memory rules for the TS-262A and TS-462A

QNAP says to use only QNAP memory modules; unsupported modules may degrade performance, cause errors or stop the system starting.

QNAP's specification does not mention ECC for the TS-262A and TS-462A: it gives the memory as 4 GB SODIMM DDR4. The tables below are standard non-ECC DDR4 SO-DIMM.

DDR4 SO-DIMM modules up to 8GB, by price

Modules of the type and size the TS-262A and TS-462A take, no larger than 8GB 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.
