Compatible QNAP NAS memory kit

This 16 GB kit contains two 8 GB DDR3L SO-DIMM modules built for QNAP TS-863U, TS-863U-4G and TS-863-RP-4G servers. It targets administrators who need to reach the 16 GB maximum supported by the two available slots. Buyers using other QNAP models or non-QNAP platforms should verify compatibility before ordering.

Verify slot count and current modules

The TS-863U series provides two memory sockets with a 16 GB limit, so this kit fills the system completely. Confirm that your unit is one of the three listed models and that no larger modules are already installed. The kit is non-ECC unbuffered DDR3L at 1.35 V; mixing with ECC or registered DIMMs is not supported.

Low-profile SO-DIMM design for dense bays

Modules use a standard 204-pin edge connector without a heat spreader, keeping height minimal for tight NAS chassis. CL11 11-11-11 timing at 1600 MHz delivers the rated PC3L-12800 bandwidth. Major-brand chips are used throughout, and Computer Memory Solutions backs the kit with a limited lifetime warranty when purchased directly.

Questions about this item

Does the kit contain both modules or do I need to buy a second stick?

The package includes two 8 GB DDR3L SO-DIMM sticks, giving 16 GB total with nothing else required.

My TS-863U has two slots — should I choose the 2 x 8 GB kit or a single 16 GB module?

The 2 x 8 GB kit fills both slots and enables dual-channel operation, which the TS-863U supports for higher throughput.

What does the PC3L-12800 rating mean for actual NAS performance?

It indicates 1600 MT/s transfer speed at 1.35 V with CL11 latency, the native spec the TS-863U memory controller expects.
