Synology UC3200 DDR4 ECC upgrade

This 16 GB DDR4 2666 module adds ECC unbuffered memory to a Synology UC3200 NAS. It runs at 1.2 V with CL19 timing and uses a 288-pin UDIMM form factor. The single stick provides 2Rx8 organisation for straightforward capacity expansion.

Best for UC3200 owners needing ECC reliability

Buyers who want ECC error correction for data integrity in a Synology UC3200 will benefit. Those whose NAS requires registered or load-reduced DIMMs, or who need a different speed or voltage, should look elsewhere. Non-ECC systems cannot use this module.

Check UC3200 slot count and maximum capacity

Verify how many UDIMM slots your UC3200 has free and the total memory limit supported by its firmware. Confirm the board accepts 2Rx8 unbuffered ECC at 2666 MT/s and 1.2 V. Ensure no BIOS or firmware restriction blocks 16 GB single-rank modules.

Questions about this item

Do I need a Synology UC3200 NAS to install this DDR4 2666 ECC UDIMM?

Yes, the module is validated for the Synology UC3200; the system must accept 288‑pin DDR4 ECC unbuffered UDIMMs at 1.2 V.

Will this 16 GB stick run with my existing 8 GB DDR4 2666 ECC modules?

It will operate at the common 2666 MT/s speed and CL19 timing; mixed capacities are supported if the UC3200 memory slots allow mixed‑rank population.

How can I confirm the 16 GB ECC UDIMM is recognised after installation?

Open DSM Control Panel → Info Center → Memory; the total should show the added 16 GB and the status must read “Normal” with ECC enabled.
