We've had trouble with a 512 box and our GPU has 16GB of RAM.  I didn't think of the padding for some reason.  Thanks we'll definitely give that a try.

Hi,

What is the box size and how much GPU memory do you have in ONE card?

Anyway, you can set 'Skip padding: Yes'. With GTX 1080 Ti (11 GB RAM), you can refine up to 1000 px box with this option.

Best regards,

Takanori Nakane
