OWC 16GB DDR4 ECC UDIMM for Synology NAS

This OWC module provides 16GB of DDR4 2666MHz ECC unbuffered memory in a single 288-pin DIMM. It is validated for Synology RackStation RS1619xs+ and RS2818RP+ systems. The CL19 2Rx8 stick runs at 1.2V and meets JEDEC standards.

Who should use this and who should not

NAS owners expanding RS1619xs+ or RS2818RP+ units with supported ECC RAM will benefit. Builders needing non-ECC memory, registered DIMMs, speeds above 2666MHz, or capacities beyond 16GB per slot must select different modules.

The deciding specification: ECC unbuffered DDR4 2666

This stick is ECC unbuffered DDR4 at 2666MHz (PC4-21300). If your Synology model requires registered memory, non-ECC memory, or a different DDR generation, this part will not function correctly.

商品問答

Will this 16GB DDR4 2666 ECC UDIMM run alongside my existing 2133MHz or 2400MHz modules in the RS1619xs+?

Yes, the module is backward compatible with 2133MHz and 2400MHz speeds and will downclock to match the slowest installed DIMM.

How can I verify the 2Rx8 ECC UDIMM is recognised correctly after installing it in my RS2818RP+?

Check the Synology DSM Info Center; it will list the new 16GB module at 2666MHz with ECC active and show total system memory increased by 16GB.

Does the 288-pin 1.2V DIMM ship alone or with any tools or extra cables for the RackStation upgrade?

Only the single 16GB DDR4 2666 CL19 ECC UDIMM is included; no tools, cables or additional hardware are supplied.
