I wanted to upgrade my memory for my QNAP TS-453A. I really only needed 8 GB (maximum supported) but I found out that people had squeezed in 16 GB without any issues… challenge accepted:)
The QNAP TS-453A should support most DDR3L memory modules. The trailing “L” is very important and stands for low voltage (1.35 V instead of 1.5 V). So I acquired a matching pair of compatible memory modules (Corsair Vengeance 16GB (2x8GB) / DDR3L / CL9 / 1600MHz / CMSX16GX3M2B1600C9).
The video here demonstrates the very simple physical procedure of opening up the enclosure and swapping the memory modules (only 3 screws!).
I did exactly as in the video and swapped both memory modules, booted up the NAS and behold it worked flawlessly:
Conclusion
Officially the QNAP TS-453A does not support 16 GB of RAM, but it does work without any issues as the system status picture above shows.
Now for next question, what should I use all that memory for…
