OWC 16GB DDR4 ECC UDIMM Kit

This OWC memory kit provides 16GB of capacity through two 8GB modules. It uses DDR4 technology running at 2666MHz with a CL19 latency. The modules are unbuffered ECC UDIMMs operating at 1.2V and conform to the PC4-21300 standard.

Suited for Synology RS3617RPxs upgrades

This kit is validated for the Synology RackStation RS3617RPxs, offering a warranty-safe upgrade path. It also supports backward compatibility with 2133MHz and 2400MHz systems. Buyers needing registered or load-reduced DIMMs should look elsewhere, as these are unbuffered modules.

288-pin DDR4 ECC unbuffered specification

The decisive specification is the 288-pin DDR4 ECC unbuffered DIMM form factor with 1Rx8 rank organisation. Only systems accepting this exact module type and pin count will recognise the memory. Verify your platform requires unbuffered ECC UDIMMs before purchase.

商品問答

Does the Synology RS3617RPxs need all four DIMM slots filled for this 2x8 GB kit to work?

The RS3617RPxs runs dual-channel memory, so the two 8 GB modules can operate together without populating every slot.

Will these 2666 MHz ECC modules down-clock if I keep older 2133 MHz sticks in the same NAS?

Yes, the kit is backward compatible with 2133 MHz and 2400 MHz systems, so mixed speeds will run at the lowest common frequency.

How can I confirm the 16 GB upgrade is recognised at 2666 MHz with ECC active after installation?

Check the Synology DSM Resource Monitor or the boot-time memory summary; it should show 16 GB total, 2666 MT/s, and ECC enabled.
