Frequently Asked Questions (FAQs)

Q1: Which models support this module?
Officially compatible with Synology 22‑Series NAS: DS3622xs+, DS2422+, RS822/RP+, DS923+, DS723+.

Q2: Can third‑party RAM be used instead?
While some third-party ECC modules may work, Synology emphasizes official modules for guaranteed stability and warranty compliance.

Q3: What does ECC provide?
ECC detects and corrects single-bit errors, preventing silent corruption critical in storage and virtualization environments.

Q4: How much performance gain can I expect?
Increased RAM enables better cache usage, smoother multitasking, and performance gains in DSM apps, VMs, and container services.

Q5: Can I mix this with other RAM modules?
No—you should install identical D4ES01‑16G modules to maintain ECC functionality and system stability.

Q6: How do I install it?
Power off your NAS, insert the SO‑DIMM into the appropriate slot, then reboot. DSM will automatically detect the added memory.
