OWC 8GB DDR4 2666 SODIMM for QNAP NAS

This 8GB DDR4 2666 CL19 SODIMM module is built for QNAP TS-873, TS-932PX, TS-932X, TVS-473 and TVS-473e systems. It suits owners of those models who need a straightforward memory increase for heavier workloads or more concurrent users. The 260-pin 1.2V Non-ECC design matches the factory specification for these NAS units.

JEDEC and ROHS compliance with lifetime warranty

The module meets JEDEC standards and is ROHS compliant, ensuring a warranty-safe upgrade that will not void the NAS manufacturer's coverage. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme. A basic installation video is available to guide the DIY fitting process.

Check your NAS model and slot availability

Verify that your exact QNAP model appears in the supported list before ordering. Confirm how many SODIMM slots your unit has and whether any are already populated, as this determines if you can add this single 8GB stick or must replace existing memory. The module is backward compatible with 2400MHz and 2133MHz systems.

Questions about this item

Will the 260-pin SODIMM slot on my QNAP TS-873 need a different module if I expand beyond this 8GB stick?

No, the slot accepts standard 260-pin DDR4 SODIMMs; you can add matching 8GB modules up to the NAS maximum without changing form factor.

What speed ceiling will the memory controller hit first when the NAS runs 2666 MHz CL19 continuously?

The JEDEC-rated 2666 MHz CL19 specification is the sustained limit; the module is tested to maintain that speed under constant load.

How much heat and power does a single 1.2 V non-ECC stick produce during all-day operation?

At 1.2 V without a heat spreader the module draws minimal power and runs cool enough for fanless NAS chassis under 24/7 workloads.
