I have a synology I bought 3rd party ram (not synology) and it works fine. Same with drives just bought some seagate drives. Probably going to upgrade from a 4 bay to a 12 and I don’t see compatibility of ram being an issue. I just don’t feel like building a whole racked system I just want to plug and play and forget. As of now tho only thing I lose is warranty cause I’m using not “certified” ram and drives.
