4GB DDR3L SODIMM for QNAP NAS

This 4 GB DDR3L module upgrades compatible QNAP TS and TVS network-attached storage units. It targets administrators who need to expand memory on the listed models without changing voltage or form factor.

DDR3L 1600 CL11 1.35 V unbuffered non-ECC

The single decisive specification is the DDR3L 1600 PC3L-12800 CL11 1.35 V unbuffered non-ECC 204-pin SODIMM profile; only systems that accept this exact combination will recognise and run the module correctly.

Sustained operation in multi-user NAS workloads

Under continuous multi-user file serving or virtualization loads the module maintains its rated 1600 MT/s throughput because the low-voltage DDR3L design keeps thermal output stable across extended duty cycles.

Questions about this item

Will the 1600 MHz speed actually run at 1600 MHz in my QNAP TS-963X?

The module is rated DDR3L 1600 PC3L-12800. In the listed QNAP models it will operate at the speed the system's memory controller sets, which cannot exceed the module's 1600 MHz rating.

Is the 204-pin DDR3L interface electrically compatible with the SODIMM slots in a TVS-863+?

Yes. The stick is a 204-pin DDR3L SODIMM running at 1.35 V, matching the slot type and voltage used by the TVS-863+ and the other listed QNAP units.

Does the single 4 GB stick fit the SODIMM socket without a heat spreader interfering with the chassis lid?

The module has no heat spreader, so its height is the standard low-profile SODIMM dimension that clears the tight clearance in the compatible QNAP NAS chassis.
