FAQs

Q1: Is this compatible with non‑Synology systems?
Technically, it may work in ECC-compatible motherboards, but Synology only supports and guarantees it in approved NAS units. AmazonProvantage+2Provantage+2CDW+2

Q2: Can I mix this with other RAM modules?
No—all installed modules must be identical (same model) to maintain ECC function. MemoryC+12Synology Download Center+12Synology+12

Q3: Does ECC reduce system speed?
ECC adds minimal latency but delivers vital data correction—ideal for storage reliability.

Q4: Will I notice performance gain?
Yes—especially in multi-user, file server, or virtualization setups on compatible NAS models.

Q5: How do I install it?
Power off your NAS, insert the module into a free DIMM slot, then restart. DSM will detect and apply the new RAM.

Q6: Is this the same as D4EC‑2666‑8G?
No. D4EC is for enterprise models like SA/UC/RS; D4EU01‑8G targets FS2500 and selected RackStation/FlashStation models.
