OWC 16GB DDR4 ECC SODIMM for Synology NAS

This 16GB DDR4 2666MHz CL19 ECC unbuffered SODIMM is designed for Synology DiskStation DS1823+ and DS2422+ systems. It adds 16GB of error-correcting memory to compatible NAS units. The module suits administrators who need data integrity for storage workloads.

Tool-free slot installation

The 260-pin SODIMM inserts directly into the NAS memory slot without tools. It operates at 1.2V and is backward compatible with 2400MHz and 2133MHz systems. The only common issue is forgetting to power down the unit fully before inserting the module.

Sustained ECC operation at JEDEC standard speeds

Under continuous load the memory maintains 2666MHz CL19 timing with ECC active, correcting single-bit errors without performance penalty. The 2Rx8 organisation supports steady throughput for multi-user file services and virtualisation tasks. It is not for systems that require registered DIMMs or non-ECC memory.

商品問答

How can I confirm the 16GB DDR4 2666MHz ECC SODIMM is recognised at the correct speed after installing it in my DS1823+?

After installation, open DSM Control Panel, go to Info Center > System, and verify the memory section shows 16GB running at 2666MHz with ECC enabled.

What comes in the box with the OWC 2C6D42R816GB module and what else might I need for the DS2422+?

The package contains one 16GB 260-pin DDR4 2666 CL19 ECC unbuffered 2Rx8 SODIMM at 1.2V. No extra parts are required if a slot is free; buy a second identical module to populate both channels.

Should I choose the 16GB 2666MHz CL19 ECC SODIMM or a lower-speed version for my DS1823+?

Select this 2666MHz CL19 module; it is JEDEC-standard and backwards compatible with 2400MHz and 2133MHz, so it will run at the highest speed the NAS supports.
