Rendering in High Resolution

hi all. I have a question about High Resolution Rendering in Movie Render Queue. I want to render an image at 12k in Path Tracing mode, unfortunately Rtx 2080 only gives me 6k. I tried to use HighR Render, but all without result, UE was closed with the same error of lack of video memory. What am I doing wrong? How to properly render such a large image? Also, there is a Metahuman in the scene, I saw that there are additional settings for subsurface scattering. Do I need to use them somehow or not? Thanks

Hey there,
could you Share your settings for the High Resolution Renderings (If you still have the problem)?
