Hi, I'm new here....

And, I need help...

I'm trying to run 2 v2 in SLI, but I get protests from my computer:

1. My other graphicscard gets overheated (Geforce 3)
2. I get strange colors in Unrealtournament (much things get pink)
3. It doesnt run any faster with 2 cards, same framerate
4. I dont really know how to set up SLI, I have the flat cable between the 2 cards, and, I used the cable on the back of the comp aswell...
5. The cards are not of the same brand, 1 is an Orchid Righteous 3D 2, and the other one I don't know, but it got 110Mhz memory...

So:
What did I do wrong, and what can I do???

Regards
Patte
