I am using Ubuntu 15.10, and I wanna upgrade my ram, will I have to install Ubuntu again or the installed one will do?

Thank you, one more favour? And is it better to install a 8GB ram, or 4 Gb ram, as 4Gb is default and maximum memory is 8 GB
 


pardon my lateness. more ram, if supported, is almost never a bad thing.
