The Synology 16GB DDR4 2666MHz ECC Unbuffered DIMM Memory Module (D4EC-2666-16G) is engineered specifically for high-capacity Synology DiskStation and RackStation Network Attached Storage (NAS) servers. Operating at a bus speed of 2666 MT/s (PC4-21300), this enterprise-grade memory module expands system buffer capacity, accelerates file system indexing, and optimizes performance for resource-heavy multi-user NAS workloads.
Built on a 288-pin UDIMM architecture operating at an energy-efficient 1.2V standard voltage, this module integrates robust Error-Correcting Code (ECC) technology. The onboard ECC engine continuously detects and corrects single-bit memory data errors in real time, preventing system crashes, data corruption, and file integrity loss during critical multi-gigabit transfers, snapshot creation, and virtual machine execution.
Available from DataDive, your trusted Technology Hardware Supplier in Qatar, this genuine Synology 16GB DDR4 RAM expansion module is available in our Memory collection, ideal for NAS memory expansion, storage pool performance tuning, virtualization node support, and enterprise backup repository optimization across Synology 20-series, 21-series, and 22-series NAS systems.
