Frequently Asked Questions (FAQs)
Q1: Which Synology models can use this module?
Compatible with high-end models such as SA3200D/SA3400D, UC3200/UC3400, and multiple RS/FS rackmount systems listed in the spec sheet.
Q2: Can it be used in desktop PCs?
No—designed exclusively for Synology NAS; compatibility and ECC validation are not guaranteed for PCs.
Q3: Do I need ECC memory for my NAS?
ECC ensures data integrity, particularly valuable for virtualization, database, or business-critical environments.
