Synology NAS DDR3 ECC kit

This OWC kit supplies 8 GB of DDR3 ECC UDIMM memory in a matched pair of 4 GB modules. It is built for the Synology DS3615xs, RS3614RPxs, RS3614xs and RS3617xs NAS units. The modules run at 1600 MHz with CL11 latency at 1.5 V. Unbuffered ECC adds error correction for data integrity in always-on storage workloads.

Upgrade from non-ECC or lower capacity

The kit replaces standard unbuffered DDR3 that lacks error correction or smaller-capacity sticks that limit the NAS to 4 GB or 8 GB total. The jump is worth it when the workload demands ZFS scrubbing, virtualisation or multi-user file services that benefit from ECC protection and the full 8 GB ceiling these bays accept. Buyers who need registered DIMMs or speeds above DDR3 1600 cannot use this kit.

240-pin UDIMM slot fit

Each stick uses the 240-pin UDIMM form factor and draws 1.5 V, so it seats directly in the four DIMM slots on the target Synology mainboards without adapters. The low-profile design without heat spreaders clears standard server chassis airflow paths. Installing the pair in matched channels enables dual-channel bandwidth for the memory controller. Systems that require registered or load-reduced modules are not compatible.

Domande su questo articolo

Does this kit use 240-pin DDR3 UDIMM modules that fit the DS3615xs and RS3617xs slots?

Yes, each 4 GB module is a 240-pin DDR3 1600 PC3-12800 CL11 1Rx8 ECC unbuffered DIMM at 1.5 V, matching the DS3615xs, RS3614RPxs, RS3614xs and RS3617xs specifications.

What is the correct installation sequence for the two sticks in a four-slot Synology NAS?

Power down the NAS, open the chassis, populate the lowest-numbered slots first — typically slot 1 then slot 3 — press each module until the retention clips click, then close the case and power on.

Will the ECC unbuffered DIMMs need any firmware update or battery replacement over time?

No firmware or battery is required; the modules are JEDEC-standard 1.5 V DDR3 ECC unbuffered DIMMs with no heat spreader, so only occasional dust removal from the slots is needed.
