Synology NVR Memory Upgrade

This OWC module adds 16GB of DDR4 ECC SODIMM memory to Synology Deep Learning NVR models DVA3219 and DVA3221. It runs at 2666MHz with CL19 latency and operates at 1.2V. The unbuffered 2Rx8 design fits the 260-pin slots in these appliances.

Replaces Lower-Capacity DDR4 ECC SODIMMs

The upgrade is worthwhile when the NVR runs multiple analytics tasks or virtual machines and the installed memory limits concurrent workloads. Backward compatibility with 2400MHz and 2133MHz systems allows use in older slots, though the module will downclock to the bus speed.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors during continuous operation, protecting data integrity in always-on recording and inference jobs. The JEDEC-standard 1.2V voltage keeps power draw steady under load. Without a heat spreader, airflow in the NVR chassis manages thermals during extended sessions.

Perguntas sobre este artigo

Will the 260-pin DDR4 SODIMM fit the memory slots in my Synology DVA3219?

Yes, this module uses the standard 260-pin DDR4 SODIMM form factor required by the DVA3219 and DVA3221.

Is there a specific orientation or slot order I must follow when installing this single 16GB stick?

Align the notch on the module with the key in the slot, press firmly until the side clips click, and use the primary slot first if the bay is empty.

Does the ECC unbuffered design require any firmware updates or periodic re-seating over time?

No firmware update is needed for the ECC unbuffered module; it runs at 1.2V and is designed to remain seated for the system's life.
