Scratching my head at SLI, help?!

[-fedexer-]

So i'm about to get rid of my old pc to my father in exchange for the one i'm currently going to be building, however before taking it off of my hands he wanted me to add the second nvidia 9600GSO card i bought a couple of years back so he can have 2x 9600GSO in SLI.

Now i've connected both cards to the mobo, and even flipped over the chip card on the mobo which states it's using dual video cards... and yet i boot into windows and nvidia control panel states: "For optimal 3D performance, connect the SLI-ready graphics cards with an SLI connector.". And now i'm lost.. i thought that was what i had enabled on the mobo with the chip flip.. (however all the images i see of SLI cards 9600GSO have a like bridge between both cards)

Am i missing something here? Is there something else i need to connect both cards in SLI which i don't seem to have? :S

Thanks for the help!

According to a very old original order sheet i just found, it's a A8N-SLI DELUXE.

Do you not have a connector block for the top of the cards to link them there?

I don't however the mobo compencates for this

Thanks for the help guys, i've been fiddling more with the nvidia settings, and downloaded gpu-z, and i've now got the SLI working
