Thanks for getting in touch, and glad you’ve been getting good use out of the DS1019+ all these years.
In short — yes, 16GB is still the maximum unofficially supported memory on the DS1019+, even in 2025. Synology only officially supports 8GB (2x4GB), but in practice it handles 2x8GB (16GB total) just fine for most users, especially when streaming and handling larger media libraries like yours.
Just be sure to use low-voltage DDR3L 1866 SODIMM modules (1.35V). Crucial or Kingston have been reliable options for this system historically. Also, keep in mind that while 16GB helps with overall multitasking and smoother operation, it won’t directly impact media streaming performance unless you’re running additional services like Docker containers, virtual machines, or heavy indexing tasks.
If you haven’t done it recently, giving the NAS a clean-out (dust, airflow) and checking your drives’ health wouldn’t hurt either as part of the TLC you mentioned.
