Hi! I am using 2x ATI Radeon 3800, they show up in the device manager, but I am unsure if they are both being used. My OS is windows 7 home premium 32bit. I enable the crossfire under the "Performance" tab. But when I hit "apply" it change the option back to "disable" Like on the picture in the followin link: http://img849.imageshack.us/img849/9224/amdvisiony.jpg
Anyone that know why this might be happening? Is the crossfire on even if it is in that option? Please help!

I had this problem with my dual 6770's what I did was did the crossfire thing then when it automatically went back to disabled after I tried to enable it I restarted my computer and then it was enabled.
