My second PCIe slot does not work with video cards. Either it activates the one in the first PCIe slot, or the onboard if its missing.
I don't know about your specific mainboard, but I needed to buy a new one. Title: Re: Motherboard with onboard video Post by: Spadowsky on June 10, 2011, 10:53:16 AM Have you tried crossfire?

My second PCIe slot does not work with video cards. Either it activates the one in the first PCIe slot, or the onboard if its missing. Have you tried dummy plugs?I don't know about your specific mainboard, but I needed to buy a new one. I've heard many people use the onboard video to drive the monitor and use the other slots to mine. It's supposed to speed up mining as doesn't have to draw the screen.

I did 2 seperate monitors to each of the card. But even with only 1 card connected to the second PCIe slot, it does not even start (fan goes to 100%, long beep from bios and black monitor).
