16 GB DDR4-2400 UDIMM for QNAP NAS

This single 16 GB DDR4-2400 CL17 module targets owners of QNAP TS-1232XU, TS-1232XU-RP, TS-1232PXU, TS-1232PXU-RP and TS-1273U systems who need more memory for virtualization or heavy multitasking. It runs at 1.2 V as a non-ECC unbuffered 2Rx8 UDIMM and meets JEDEC PC4-19200 specifications.

Replaces QNAP RAM-16GDR4A0-UD-2400

The jump is worthwhile when your NAS hits its factory memory ceiling during container workloads, large file transfers or multiple simultaneous users. Backward compatibility with 2133 MHz slots means the module will clock down safely if the platform requires it.

Verify open 288-pin DDR4 slots

Confirm the unit accepts non-ECC unbuffered UDIMMs and that total installed memory will not exceed the model's official limit. ECC-only or registered-DIMM systems cannot use this module.

Questions about this item

Will this 288-pin DDR4 module fit the DIMM slots on my QNAP TS-1232XU?

Yes, the 288-pin DDR4 UDIMM form factor matches the memory slots used by the TS-1232XU and the other listed QNAP models.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips click into place, and verify the module sits level; the step often missed is pushing hard enough to engage both clips.

When will this 16 GB stick need to be replaced?

DDR4 memory has no moving parts and no scheduled replacement interval; it typically lasts the life of the NAS unless a fault develops.
