If it is a GPU memory issue, perhaps enabling the out of core feature could help.
I've done some tests, rendering with all combinations of GPUs, only seconday GPU, only display GPU, then both turned on.
My main GPU is 1080ti and my second one is a 1080 so i don't really think its a GPU memory problem since the scene is 3gbs. I had no issues when rendering with a single GPU. The issue arises when i turn both of them on. Every single time i try to render with both of them, the scene loads and starts to render and at some point IPR goes "gray" and it unloads the object.
