According to the service manual (on page 2), your Intel i3 6th gen processor-based model supports 16 GB (2x8 GB) DDR4-2133 memory.

If you want to upgrade to 16 GB, you can do so by adding another 8 GB module to the second slot.
DDR4-2133 is not widely available nowadays. You can use DDR4-2400 or 2666. Either frequency will automatically downclock to 2133.
A couple of examples of RAM you can use:

Thank you for your reply.
According to you, is it enaough to install only 1 module (in this case i will have 2 modules of different producers) or is it better to have 2 modules of the same producer (in this last case i should buy 2 modules of those you recommended to me)?
Thank you for your reply

You can install an 8 GB memory of a different manufacturer in the second slot.
Just avoid performance and gaming memory such as Corsair Vengeance and Kingston Fury to prevent compatibility issues.
