QNAP NAS Memory Upgrade

This OWC module adds 8 GB of DDR4 memory to compatible QNAP TVS-1282 and TVS-682 series NAS units. It targets owners who need extra capacity for virtualization or heavy multi-user workloads. The single stick installs directly into an available UDIMM slot without requiring matched pairs.

288-Pin UDIMM Fit

The stick uses the standard 288-pin DDR4 form factor and runs at 1.2 V, drawing minimal power from the NAS chassis. It requires a free unbuffered DIMM slot and a motherboard that accepts non-ECC memory at 2133 MHz. No heat spreader is fitted, so airflow inside the enclosure handles cooling.

Sustained CL15 Operation

Rated at CL15 latency, the module maintains consistent timing during extended file transfers or database tasks. JEDEC compliance ensures stable voltage regulation across long uptimes. Builders who need ECC error correction or registered buffering should look elsewhere.

Questions about this item

How much power does the 1.2V module draw during continuous NAS workloads?

The DDR4 2133 CL15 2Rx8 UDIMM operates at 1.2V standard voltage without a heat spreader, so sustained power draw stays within JEDEC limits for unbuffered DDR4.

Will the bare PCB run hot or noisy inside a TVS-1282T3 chassis?

With no heat spreader and standard 1.2V operation, the module relies on the NAS internal airflow; it adds no active cooling noise and temperatures follow chassis fan curves.

Which QNAP models must I already own for this 288-pin DDR4 to be compatible?

This 8GB PC4-17000 CL15 2Rx8 kit is validated for TVS-1282, TVS-1282T, TVS-1282T3, TVS-682 and TVS-682T systems.
