Synology D4ER02-32G
32GB DDR4 DIMM 288-pin Registered RAM Module
The Synology D4ER02-32G is a high-capacity 32GB DDR4 Registered DIMM Memory Module designed for enterprise-grade Synology servers and high-end NAS systems. The “registered” designation means it includes a register buffer that reduces the electrical load on the memory controller, enabling the use of a larger number of memory modules and significantly increasing overall system capacity. This module is essential for businesses running mission-critical applications, large virtualized environments, and other memory-intensive workloads that require maximum stability and performance.
As a genuine Synology product, the D4ER02-32G is rigorously tested and validated for full compatibility with specific Synology models. This ensures seamless integration, optimal performance, and the highest level of reliability, which is crucial for preventing system crashes and data corruption in a professional setting.
Features :
The Synology D4ER02-32G offers a substantial performance boost for your server. With 32GB of DDR4 memory, it allows you to run multiple virtual machines, handle large-scale database operations, and support a greater number of concurrent users with ease.
