Synology - DDR4 - module - 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
