Question HP 450 G4 RAM upgrade

Jul 30, 2019
I have a HP 450 G4 with a 4GB DDR3 and I wanna bump it up as much as possible. I saw that it only goes up to 8GB on the HP website. I also have an old 450 G0 which goes up to 16GB. How is that possible?
I want to at least go up to 12GB. Can this be done? :)
