Synology ECC Unbuffered 8GB (1 x 8GB) DDR4 2666 MHz Memory

The Synology D4EC-2666-8G is an 8GB DDR4 memory module specifically engineered for use in compatible Synology NAS and server platforms. Operating at a frequency of 2666 MHz, it is designed to expand system memory, which can improve multitasking capabilities and overall responsiveness under heavy workloads. This module features Error-Correcting Code (ECC) technology, which automatically detects and corrects single-bit memory errors as they occur. This function is a critical component for maintaining high levels of data integrity and system stability in always-on, mission-critical server environments.

As an official Synology component, this memory module has undergone rigorous testing to ensure optimal compatibility and reliability with a range of RackStation and NAS systems. It utilizes the standard 288-pin DIMM form factor and operates at an efficient voltage of 1.2V. As an unbuffered DIMM, it provides a direct memory upgrade path for supported devices. This facilitates smoother operation for demanding applications such as virtualization, large-scale file transfers, and concurrent multi-user access without compromising system stability.
