- 260-pin SoDIMM fits compatible laptop and NAS slots
ECC SoDIMM for Synology DS 1819+
This 16 GB DDR4-2666 module adds error-correcting memory to compatible Synology NAS units. It runs at 1.2 V with CL19 latency and a 0.75 ns cycle time. The 260-pin SoDIMM form factor fits the memory slots of the DS 1819+ and similar platforms that require ECC unbuffered memory.
Lifetime warranty and ECC protection
The manufacturer provides a lifetime warranty on this module. ECC circuitry detects and corrects single-bit errors to maintain data integrity during continuous operation. Unbuffered design keeps latency low for the 2666 MHz transfer rate. PC4-21300 bandwidth supports demanding file services and virtualization workloads.
16 GB capacity for multi-service NAS
A single 16 GB stick expands memory headroom for Docker containers, virtual machines and large file caches. Dual-rank organisation (2Rx8) maximises density within one slot. Systems needing more than 16 GB total will require additional modules. Non-ECC platforms cannot use the error-correction feature.

Questions about this item
Will the ECC unbuffered design require any firmware updates or module replacements over time?
The module is a standard 260-pin SoDIMM with a lifetime warranty and no moving parts; it does not need firmware updates or scheduled replacement.
What limits sustained throughput on this CL19 2666MHz stick?
The fixed CAS 19 latency and 2666 MHz data rate set the maximum sustained bandwidth the module can deliver.
How much heat and power does a 1.2 V 16 GB ECC SoDIMM produce during all-day operation?
At 1.2 V the module draws minimal power and runs cool enough for continuous use in compact NAS chassis such as the DS 1819+.
