I was using my system with single 980Ti because I feared my 620W Seasonic PSU can't handle my dual 980Ti under load. Then I wanted to give it a try with idle usage. But NVIDIA control panel can't enable the SLI.
Both cards are recognized (I checked with GPU-Z as well)
I connected SLI bridge to different slots with different orientations but still no go... Do you think it is a power related issue?
What do you suggest?
