Run a second instance of your miner, then set it up with the second card.

If disabled you will have to connect the second card to a monitor or use a dummy plug.Title: Re: should i enable or disable crossfire Post by: anewbie on May 29, 2011, 11:30:27 PM i did when i launch my miner one worker is device 0 and the other is 1. when i disable crossfire no matter what i change the device to it either uses the cpu, or does not run at all. You must be using Windows. You need a dummy VGA plug: http://www.geeks3d.com/20091230/vga-hack-how-to-make-a-vga-dummy-plug/ (http://www.geeks3d.com/20091230/vga-hack-how-to-make-a-vga-dummy-plug/). Windows will not enable the GPU unless it thinks there is a monitor installed.

It has something called virtu on it that might allow me to do it. I start with one ati then after I start that i go to the next ati then after that i use the sandy bridge intel graphics as my main, this way it only use 33% of the cpu and the computer, graphics and youtube still work perfectly.
