Crashing issues

my town is starting to get bigger, around 25, and the game will not stop crashing.
from what ive read online having to force 32bit caps ram at 2gb? is there any way to increase this?
i have a pretty decent pc and its getting frustrating. Any suggestions are very helpful.
I am running modded (35 mods 20~ content 15 templates), windows 10, 64gb ram, 3080, 12900k
