QNAP NAS 4GB DDR3L Upgrade

This OWC module adds 4GB of DDR3L memory to compatible QNAP NAS units. It runs at 1600MHz with CL11 latency and operates at 1.35V. The 204-pin SODIMM format fits the listed QNAP TBS-453A and TS-1253 series models directly.

Suitable for expanding listed QNAP models.

Builders upgrading a QNAP TBS-453A, TS-1253BU, TS-1253BU-RP, TS-1253U or TS-1253U-RP can install this module without configuration changes. Buyers whose NAS requires a different pin count, voltage or DDR generation should select a module matching those specifications.

204-pin DDR3L SODIMM at 1.35V

The decisive specification is the 204-pin DDR3L SODIMM interface running at 1.35V. Only systems designed for this exact form factor and voltage will accept the module; all other platforms are physically or electrically incompatible.

Questions about this item

Does my NAS need a free 204-pin SODIMM slot to install this module?

Yes, the 4 GB DDR3L stick uses the standard 204-pin SO-DIMM form factor and fits any vacant slot in the compatible QNAP models.

Will this 1.35 V DDR3L module run correctly in a system that currently uses 1.5 V DDR3 memory?

The module operates at 1.35 V and is designed for DDR3L platforms; mixing voltages is not recommended for the listed QNAP units.

How can I verify the 1600 MHz CL11 speed is active after installation?

Check the system information or resource monitor in the QNAP OS; it will report the installed memory running at PC3L-12800 1600 MHz with CL11 timing.
