OK So my problems continue.

I have a problem with my SLI. The nvidia drivers wont find my second 780 Lightning.

I am mixing Lightning and Lightning LE cards but they are the same spec just different clocks. But the Nvidia driver just wont see the second card.

GPUZ see's both cards

Any ideas?

Did you actually enable it? I don't think it's automatically configured (at least that's what happened to my GTX 770 SLi).

You have to go into 3D setting in nvidia control panel. Are you seeing them both in gpuz? Also I had kinda the same problem. I pulled both cards out and installed one. Then rebooted and installed the other.

My motherboard did that stuff too. It wasn't the cards at all.

same here to many new hardware found -580sli to 780 sli needed 3 cold reboots.
take note of how many nv hdmi sound devices you have now [x8]
and nuking them in device manager is the best practice.
 
I don't know how many times I had to switch the cards around and then everything was fine.

Let this be a lesson to everyone: try the simple things 1st.
