OWC 8GB DDR4 ECC UDIMM for Synology SA3200D

This single 8GB module is built for the Synology RackStation SA3200D and other systems that accept 288-pin DDR4 ECC unbuffered DIMMs. It runs at 2666MHz with CL19 latency and 1.2V power draw. The 1Rx8 rank layout fits the memory controller requirements of the target NAS platform.

Sustained-load behaviour

Error-correcting code detects and corrects single-bit errors during continuous operation, reducing silent data corruption in multi-drive arrays. JEDEC-standard timings and ROHS compliance keep the module stable at rated speed without voltage overrides. Backward compatibility with 2133MHz and 2400MHz buses allows the DIMM to clock down automatically when the platform demands it.

Pre-installation checks for NAS memory upgrades

Verify that your SA3200D chassis has a free 288-pin UDIMM slot and that the current firmware supports the total capacity you plan to reach. Confirm the existing modules are also unbuffered ECC DDR4 so ranks and timings remain consistent across channels. The module has no heat spreader, so ensure airflow over the DIMM area is adequate for prolonged workloads.

Questions about this item

Does the 1.2V DDR4 module run cooler than higher-voltage sticks in a Synology SA3200D running 24/7?

The 1.2V JEDEC-standard voltage keeps power draw low, reducing heat output during continuous operation in the RackStation.

Must the SA3200D already support ECC unbuffered DDR4 for this 288-pin DIMM to function?

Yes, the NAS needs DDR4 ECC unbuffered slots; the module is validated for the SA3200D platform.

Will the 2666MHz CL19 stick downclock automatically if I keep older 2133MHz modules in the same system?

Backward compatibility with 2133MHz and 2400MHz is specified, so the new DIMM will run at the lower speed when mixed.
