I have a 32g computer ram. and 12g video ram card. ive tried so many things ive been told to try and the one thing i cant change is go into DAZ and render setting and go to advanced tab. Check Allow CPU Fallback. the advanced button or tab or in windows isnt there. ive switched my nvidian to studio and updated my drivers. if tried altering other settings in my computer and in daz but i can not get this to work. it crashes on me every few minutes or if i try and iray the model and a light. i dont have a dforce hair on my model. or anything crazy done.

Are you looking in the right place for the fallback option? It's located in the Render pane under the Hardware tab.
DS crash might come from various causes, e.g. shortage of RAM or VRAM, Nvidia or CUDA driver incompatibility, GPU hardware failure, faulty plugins, problematic assets, etc.
Did you see a message reporting a fatal error when DS crashed ? You could save the crash report and give it an analysis 1st of all ~~
