How to use
Purchase Synology-branded memory modules from an authorized local distributor and follow the device-specific installation instructions in your Synology product manual. Power off the device and disconnect it from mains before installing or replacing memory to avoid damage. After installation, verify that the system recognizes the new memory in the Synology interface and monitor stability during normal operation.
Recommendations
For optimal compatibility and support, always use Synology memory modules recommended for your specific Synology model and keep purchase records from authorized distributors to preserve warranty and technical assistance eligibility.
