QNAP NAS Memory Upgrade

This OWC module adds 8GB of DDR4 2666 memory to compatible QNAP TVS series NAS units. It is built for owners of the TVS-672N, TVS-673e, TVS-872N, TVS-873e and TVS-951X who need more capacity for virtualization or heavy multi-user workloads. The SODIMM format fits the factory memory slots in these specific appliances.

Replaces Slower DDR4 Modules

The CL19 2666MHz speed steps up from 2133MHz or 2400MHz sticks that may ship in base configurations. The upgrade is worth it when the NAS runs multiple containers or VMs and the current memory limit causes swapping to disk. JEDEC compliance ensures the new module runs at the correct voltage and timings without manual tuning.

Single 260-Pin SODIMM for Empty Slot

The 1Rx8 unbuffered non-ECC stick installs in a free 260-pin slot and operates at 1.2V. It leaves any existing modules in place and frees the remaining slots for future expansion up to the system maximum. No heat spreader is fitted, so clearance inside the compact NAS chassis is not affected.

Questions about this item

Does the 260-pin SODIMM fit the memory slot in my QNAP TVS-872N?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor that matches the slot in the TVS-872N and the other listed QNAP models.

What is the correct way to seat the module so it locks in place?

Align the notch on the module with the key in the slot, insert at a slight angle, then press down firmly until the side clips click audibly.

Will the CL19 timing require any future adjustment or replacement?

No, the CL19 latency is fixed by the JEDEC-standard SPD and needs no maintenance or replacement for the life of the module.
