I have 2 pny nvidia geforce 9600gso's that not matter what i do i cannot get the sli option to appear in nvidia control panel. I have tested both cards and both work perfectly, I have tried driver sweeper still no luck. Everything is properly hooked up and all drivers are up to date. I had heard that maybe the onboard realtek ethernet driver is an issue but cant confirm it anywhere. I am scratching my head trying to figure this all out. It does show both cards in the nvidia control panel just no sli option. Below are the specs of my build. Any help is greatly appreciated and i did try older nvidia drivers still had no luck.
Mobo ASUS P8Z68-LX with latest bios
Intel i2500k With corsair h60 cooler running push pull

2 pny 9600gso GPU's

Download the latest dirvers from asus for your motherboard, and try again.
If you feel its the realtek ethernet driver causing your probs , remove it and see if the SLI still doesnt show , you can also update that realtek driver from asus and see if that makes any difference.
make sure you have the sli connector cable attached to both cards...also your sli connetor might by faulty....if you know for a fact that the cable is good then you might want to download the latest drivers and perform a clean install, hope it works for you....also look in your system properties to make sure that both cards are detected, if both of them are not detected then one of the cards might also be faulty
Just download the sli hack that forces the drivers on unsupported boards. Also are both cards the same? If one is a G92 and the other is a G94 sli will never be available.
You can usually tell which one the card is. The 192bit G92 version only has 384 or 768mb and never 512 or 1gb. The G94 is a little more confusing but many have appeared as the 128bit 512mb/1gb version.
