SLI proper connection

[coconuts4eva]

I've got 4 780s. You can see in the picture that they show up in the Nvidia control panel.

 

You can see in the other picture I have card 1 plugged into 2 and 2 into 3. I thought this would work for 3 way plus one on PhysX. However the control panel is only allowing me to configure it as 2 way. What am I doing wrong? I would use a hard bridge but the cards are all different height ...SC, Classified... etc.

A 3-way sli bridge has to connect al three cards. see the picture

So I could use a third ribbon cable and cross over from the first to the third? Also I have a 3 way hard bridge, is there anyone that makes a three way ribbon bridge?

I reccomend just using the 3-way hard bridge, I think it looks better anyway.

I would, but the cards are all 780s but not the same kind so the connectors are different heights and the hard bridge won't work because there is no flex.

So you're running standard pcb with custom pcb?

[coconuts4eva]

Pretty much.

Cant do it with those cards like he said. Regular sli bridges would be the best option.
