It doesn’t work that way CD… Don’t worry, you are far from the first to think that GPU vram is added together. This is a very common misconception. Scenes must entirely be loaded into each GPU. And if NVLink is now able to go bi-directional on RTX and can add memory together, that is news to me, if that is what you are talking about. I’m pretty sure that only Quadros have those bells/whistles. Someone correct me if I am wrong.
