Synology 8GB DDR4-2666 ECC Unbuffered SO-DIMM Server Memory (D4ES01-8G)

The Synology 8GB DDR4-2666 ECC Unbuffered SO-DIMM Memory Module (Part Number: D4ES01-8G) is an enterprise-grade RAM upgrade module specifically designed and tested for expanding the system memory of Synology DiskStation and RackStation NAS servers. Operating at 2666 MHz (PC4-21300) with a low 1.2V power requirement, this 260-pin Small Outline DIMM (SO-DIMM) enhances multitasking responsiveness, system stability, and data processing throughput during heavy file transfers and multi-user access.

Built with integrated Error-Correcting Code (ECC) functionality, this memory module actively monitors data streams to detect and correct single-bit memory errors in real time. By eliminating system crashes and silent data corruption caused by memory bit flips, it ensures maximum operational uptime and data integrity for enterprise storage nodes, virtual machine hosting, and intensive database indexing.

Available from DataDive, your trusted Technology Hardware Supplier in Qatar, this authentic Synology NAS expansion RAM is available in our Memory collection, ideal for RAM upgrades, system performance optimization, and memory expansion across compatible Synology DiskStation (DS1821+, DS1621+, DS2422+, DS1522+) and RackStation (RS1221+, RS2421+) NAS units.
