Product information

Description

The Synology DDR4 16 GB 2666 MHz memory module expands system memory capacity with a 16 GB DDR4 SO-DIMM designed for compact servers and compatible PCs. Operating at 2666 MHz and using 1.2 V power, this module supports ECC functionality to improve data integrity and reduce the risk of memory errors in environments that require stable operation. The 260-pin SO-DIMM form factor fits systems with laptop-style or compact server memory slots, allowing straightforward memory upgrades to increase multitasking and caching performance.

Advantages

This 16 GB DDR4 module delivers a balance of capacity and frequency suitable for business and home server use, small form-factor workstations, or compatible laptops. ECC support helps detect and correct single-bit memory errors, improving reliability for storage servers and network appliances. The low 1.2 V operating voltage reduces power consumption and heat generation compared with older memory types, while the 2666 MHz clock speed provides responsive system behavior for memory-bound tasks.

Suitable for

  • Upgrading memory in compact servers and NAS devices that accept 260-pin SO-DIMM modules
  • Increasing multitasking capacity in compatible laptops and small form-factor PCs
  • Enhancing stability and data integrity in storage and backup servers where ECC is supported

Key specifications

  • Capacity: 16 GB
  • Type: DDR4
  • Clock speed: 2666 MHz
  • Form factor: 260-pin SO-DIMM
  • Operating voltage: 1.2 V
  • Error correction: ECC support

How to use

Power off the system and disconnect power before installing the memory module. Open the access panel to locate the SO-DIMM slot, then align the moduleâs notch with the slot and press down until the retaining clips engage. After installation, reconnect power and start the system; verify that the operating system or system BIOS/UEFI recognizes the additional 16 GB of memory and ECC status if applicable. Follow the device manufacturer's service manual for any specific procedures or compatibility notes.

Usage recommendations

Confirm device compatibility with 260-pin DDR4 SO-DIMM modules and ECC capability before purchasing; mix memory modules of the same type and speed for optimal stability. For systems used in critical storage or server roles, enable ECC features in system firmware when supported and perform memory tests after installation to ensure correct operation.
