That's just too big, you'd need to use the Tiled samplers.

I encountered the same problem, probably due to the upscaling algorithm used in high-resolution restoration. The larger the image, the more memory usage you will have. When I don't use these functions everything goes back to normal, at least this is what I can currently way of solving the problem. I don't recommend you use a resolution higher than 1024.
