Synology SA3600 ECC RDIMM Upgrade

This 16 GB DDR4 2666 module is built specifically for the Synology SA3600 NAS. It uses ECC registered RDIMM technology to protect data integrity in always-on storage workloads. The single 1Rx4 rank runs at 1.2 V with a CL19 latency profile.

Verify Slot Count and Population Rules

Before ordering, confirm how many memory slots your SA3600 chassis provides and whether the existing configuration requires matched pairs or specific slot ordering. The system accepts 288-pin DDR4 RDIMMs only, so UDIMM or SO-DIMM modules will not fit. Check the current firmware version as well, because some revisions enforce strict vendor whitelists.

Sustained Load Stability With ECC Correction

Under continuous operation the registered buffer reduces electrical load on the memory controller, keeping signal quality consistent during long backup or replication jobs. ECC circuitry corrects single-bit errors on the fly, preventing silent data corruption that can accumulate over days of heavy throughput. The 1.2 V operating point helps maintain thermal headroom inside the compact NAS enclosure.

Questions about this item

Does the package include anything besides the single 16 GB DDR4 2666 ECC RDIMM module?

The package contains only one 16 GB DDR4 2666 ECC RDIMM module; no heat spreader, cables or additional components are included.

Should I choose the 1Rx4 CL19 version or a different rank and latency for my Synology SA3600?

This 1Rx4 CL19 module matches the SA3600 qualified configuration; other rank or latency combinations are not validated for that system.

Will the rated 2666 MT/s speed actually run at 2666 once installed in the SA3600?

The SA3600 memory controller operates DDR4 at 2666 MT/s, so the module will run at its rated 2666 speed without down-clocking.
