Product information

Description

The Synology D4NS01-4G is a 4GB DDR4 memory module in a 260-pin SO-DIMM form factor designed for Synology NAS and storage servers. It provides a factory-tested, compatible option for memory expansion to support data-intensive applications and improve multitasking performance on supported Synology systems.

Advantages

This Synology DDR4 memory module is designed and validated for compatibility with Synology devices, reducing the risk of system instability or boot failures associated with non‑authorized modules. The 4GB capacity in a compact SO‑DIMM format offers a balance between increased working memory and space-constrained server designs, while factory support ensures predictable behavior and access to Synology technical assistance when installed as recommended.

Suitable for

  • Memory expansion in Synology NAS and storage servers that accept 260-pin SO‑DIMM modules
  • Small form‑factor servers and compact systems requiring DDR4 SO‑DIMM
  • Light to moderate data‑intensive tasks such as file sharing, backups, and media streaming on supported Synology models

Key specifications

  • Brand: SYNOLOGY
  • Model/MPN: D4NS01-4G
  • Capacity: 4 GB
  • Memory type: DDR4
  • Form factor: 260-pin SO‑DIMM
  • EAN: 4711174726431

How to use

Power down the Synology device and disconnect it from power before installing the module. Open the access panel according to the device manual, locate the SO‑DIMM slot, and insert the module at the correct angle until the retention clips engage. Reassemble the unit, reconnect power, and start the system. Verify that the new memory is recognized in the Synology DSM or device BIOS/firmware interface.

Usage recommendations

Always use authentic Synology memory modules from authorized local distributors for optimum compatibility and reliability. Installing non‑Synology memory modules may cause system instability or boot failures and can affect warranty coverage and technical support from Synology.
