I was able to obtain 256x512 images with this card using the standard model, but ran into OOM issues.
I don't mind waiting, so now I am using the "fast" repo:
https://github.com/basujindal/stable-diffusion
With this, it takes 30s to generate a 768x512 image (any larger and I am experiencing OOM issues again). I think you should expect a bit faster at the same resolution with your 3060 because it's a faster card with the same amount of memory.
