Single 4 GB DDR3L SODIMM for QNAP NAS

This OWC module delivers 4 GB of DDR3L memory at 1600 MT/s with CL11 latency and 1.35 V operation. It uses a 204-pin unbuffered non-ECC design in a 1Rx8 configuration and carries JEDEC and RoHS compliance.

Suits owners of the listed QNAP models needing

The part matches the IS-453S, TS-1263U, TS-1263U-RP, TS-231P3 and TS-431P3. Builders who need ECC error correction, registered modules, higher capacity per stick or a different pin count should look elsewhere.

204-pin DDR3L SODIMM form factor

Only systems that accept 204-pin DDR3L SO-DIMMs at 1.35 V can use this module. A motherboard or NAS chassis wired for a different pin layout or voltage will not recognise the stick.

Questions about this item

Does the DDR3L 1600 PC3L-12800 interface limit bandwidth to 12800 MB/s?

Yes, the PC3L-12800 rating caps the maximum theoretical bandwidth at 12800 MB/s for this module.

What physical slot does the 204-pin SODIMM need to fit in a QNAP TS-231P3?

It requires a standard 204-pin DDR3L SODIMM slot inside the NAS chassis.

How is the module installed and which step is often missed?

Power off the NAS, open the case, align the notch on the 204-pin edge connector, press firmly until the side clips click, then reassemble and power on.
