Iray no longer uses GPUs

Here's the strange part, a GPU works fine (I check a single GPU to show the preview) when checked to show a viewport preview. It fails every time when I try to render it with the render button.

Apparently I fixed it by going into the Nvidia control panel and enabling SLI. I had it off because previously it would cause a massive system hit when using the preview pane with it on, but not now. Maybe the latest driver helped this? I'm going to leave this post here just in case someone else has the same issue.
What version of Studio are you running? What Nvidia driver?
