Game Crash cause of not enought ram

hey i have no idea how to write stuff like that because i usually don’t care if a game crashes but this one is different because i pay to still be able to play it but to my problem whenever i go to the dragon islands am or how the area is called after a certain time both my screens start to flicker the sound breaks after everything has calmed down I get an error code from blizzard that I don’t have enough RAM and I wanted to know if only I have this problem or if there are others who have the same problem and before anyone asks, yes, I lowered the graphics, reduced the visibility and all that other crap, I even deactivated my addons, but it happens over and over again and I’ll put my system here maybe I’m just too stupid
