QNAP TVS-882/882T DDR4 Upgrade

This OWC module adds 4 GB of DDR4-2133 memory to the QNAP TVS-882 and TVS-882T NAS units. It is a single 288-pin UDIMM rated at CL15 and 1.2 V, built to JEDEC PC4-17000 specifications. The stick is non-ECC, unbuffered and organised as 1Rx8 without a heat spreader.

Fits the TVS-882 series only

Buyers who need ECC error correction, registered DIMMs or a higher capacity per slot should look elsewhere. The module is validated solely for the two listed QNAP models and is not intended for other NAS brands, desktop motherboards or workstation platforms.

Slot-ready for the target NAS

Installation uses the existing UDIMM slots inside the TVS-882 or TVS-882T; no extra cables, brackets or power connections are required. Adding the module frees the CPU from memory pressure during multi-user file serving, virtualisation or media transcoding tasks.

Questions about this item

Does this 288-pin DDR4 UDIMM need a QNAP TVS-882 or TVS-882T NAS to operate?

Yes, the module is built to OWC part number 2U1D41R804GB and validated for QNAP TVS-882 and TVS-882T systems; it will not function in other platforms.

Can I keep my existing DDR4 2133 CL15 memory and add this 4GB stick alongside it?

The stick runs at 1.2V with CL15 timing and 1Rx8 organisation, matching the JEDEC DDR4-2133 standard used in the TVS-882/882T, so it will interleave with identical modules.

How do I confirm the NAS recognises the full 4GB after installation?

Power on the TVS-882 or TVS-882T, open the QTS control panel, go to System > Hardware and verify the total memory shows the previous amount plus 4GB.
