Synology - DDR4 - modul - 64 GB - DIMM 288-PIN - registered ECC

The Synology D4ER01-64G is a 64GB DDR4 ECC memory module specifically designed for NAS and storage servers. This single-module 64GB configuration provides increased memory capacity for data-intensive workloads while ECC technology helps detect and correct single-bit errors to maintain data integrity and system stability. For optimal compatibility and support, use authentic Synology memory modules purchased from local distributors; installing non-Synology modules may cause instability or boot failures and can void Synology warranty and technical support for memory-related issues.

Advantages

This Synology DDR4 ECC 64GB module offers a large single-module capacity useful for virtualization, heavy multitasking and large cache requirements. ECC error-correction improves reliability for continuous server operation, and the module is optimized for Synology NAS and storage server platforms to reduce compatibility risks compared with generic DIMMs.

Suitable for

• Synology NAS and storage servers requiring expanded memory
• Virtualization hosts and container workloads
• Database and file-server environments with high memory demands
• Applications needing improved data integrity and uptime

How to use

Power down the NAS or server and disconnect it from power before installing the memory module. Consult your Synology model's hardware installation guide to identify the correct DIMM slot and supported slot population rules. Install the DDR4 ECC 64GB module by aligning the notch with the slot, seating the module evenly until the retention clips engage, then reconnect power and boot the system. Verify the new memory is recognized in the system information or BIOS/UEFI interface.

Recommendations

Always select and install authentic Synology memory modules purchased from authorized local distributors to ensure full compatibility, system stability and eligibility for Synology warranty and technical support. Avoid mixing non-Synology modules with Synology-qualified modules to prevent potential instability or boot issues.
