Synology - DDR4 - module - 16 GB - DIMM 288-PIN - 2666 MHz / PC4-21300 1,2 V unbuffered ECC

The Synology D4EC-2666-16G is a 16 GB DDR4 SO-DIMM memory module for laptops and compact systems. Operating at 2666 MHz with ECC error-correction technology, it is designed to improve multitasking performance while maintaining data integrity. This genuine Synology memory module is intended for use in compatible Synology and other supported systems; using non-Synology modules may cause instability and void full Synology support.

Advantages

Provides 16 GB of DDR4 memory at 2666 MHz in a 260-pin SO-DIMM form factor, combining higher memory capacity and speed with ECC error correction to reduce data corruption risk. The module is straightforward to install in supported laptop or compact-system memory slots and is manufactured to Synology compatibility standards to help ensure stable operation when used as specified.

Suitable for

• Upgrading laptop memory to 16 GB for better multitasking
• Compact workstations or small form-factor systems requiring 260-pin SO-DIMM modules
• Environments where ECC protection for memory integrity is desired
