I have installed a GTX580 graphics card into my second pcie slot to use for searching for chains.

It is not being seen by the computer or CSA Rainbow Tool.

My main graphics card is a GTX660.
I did have another GTX 660 in my second pcie slot for chain searching and that worked fine.

I am not using them in sli mode, the second card is purely a slave for chain searching.
It has power as the fans can be seen spinning.

Anyone any ideas why the card is not being detected?

Problem solved.

The card has two power connections and both need to be connected. I had only connected one.
