Can’t find this post with such a recommendation in a quick search, but @danny, who designed Roon OS, wrote many, many times on the forum that it simply crashes if it runs out of memory, and if it doesn’t crash, more memory will do absolutely nothing. (Roon OS doesn’t swap RAM to disk).
Anyway, it won’t hurt, it cost you nothing, and RAM is not your problem. Nor should the N1 hardware generally be, with 80k tracks. Sounds like a software/library problem.
