Three video cards with only two in cf? (SOLVED)

post #1 of 17
Thread Starter 
I have been running two hd 6850's in cf for my eyefinity rig(3monitors). I have the asus crosshair V mobo and had a 2 spare monitors as well as an hd 5450 laying around. What I decided to experiment with was keeping my two cards in cf for my eyefinity and then use the spare card to power the two extra monitors that will sit in the top right side and top left side of my eyefinity group. After all said and done it will recognize all 5 displays but will not give me the little toggle to crossfire. Is there any way to force the crossfire?

Should work fine with the 6800 cards in Crossfire, and the 5450 on its own. And yes, you should be able to keep the Eyefinity displays separate from the other ones, but don't quote me on that one. It should all theoretically work fine though.

Thats what I thought but as soon as i booted up and checked CCC it has no option for crossfire, im gonna search the net for the 5450 driver cause its probably using the 6800 series driver for it. Will having two ati drivers on the same system conflict?

The same driver should work fine on all cards, as they're all recent AMD cards. Have you made sure that the cards are all in the correct slots for crossfire?

All three cards use x16 and I have three lanes. According to the mobo manual that if 3 x16 cards are used the lanse would be x16,x8,x8. Currently the cards are installed 6850,5450,6850.

Try going 6850, 6850, 5470 in that order. See if that helps.

Remove the extra card and crossfire your system, turn it off and attach the extra card, if it doesn't work the system probably won't crossfire with different series cards installed, or then its looking for a crossfire bridge for the 3rd card and wont let you. Or then its simply not letting you because the last card is of another series.

your going to need to contact someone at ati or amd to get the true answer to this question.

I could actually test this out on my own system and see if I can get it to work.

ok so i disabled the 5450 and restarted the system and it allowed me to crossfire, I reneabled the 5450 in control panel and let it install the 5450 driver for it. Now I got all the displays going and crossfire is enabled BUT if i try to make an eyefinity display group, it gets to the very first step of "select display to group, click continue to disable extended displays". I click continue but it does nothing, it doesnt hang the button just doesnt click.

create the eyefinity group before you enable the extra card, see if that does it
