Hi Ohki, 2gb ram are to less, this is a problen what has "blender cycles" and "superfly". Maybe this gives you some more information: https://docs.blender.org/manual/en/dev/render/cycles/gpu_rendering.html But the only solution is that you get a graphic card with more ram (no RTX Card they are still not supportet) or you can try to make your scene smaler that it fits the memory of your card.

• smaler image sice or less "sub division".
