      I have a ming righ with a 850W PSU and 2 asus ati 5870 and it woks fine.
      If I had a 5770 it is still working but if I replace the 5770 by a powercolor 6950 my windows crash or cgminer crash.
      I tested with all the 3 cards connected and I try to mine only with the 6950 alone using guiminer: cgminer crash again. But if I have only the 6950 ang 5770 everything works.
      I tried several version of the catalyst drivers.

      Is there a comptaibility issue or something that could explain that ? Or does anyone have a solution ?

      Thanks

        I had a similar issue. Did you overclock or underclock any of the cards? try running them all at stock speed. I had a r9 290 and a hd7950. when I OC the hd7950 is crash the AMD driver

          No I did not tried to overclock or underclock them. So this config might work ?

          Thanks

            it could work, maybe the setting for the miners are incorrect?

              I use guiminer’s settings for the 6950 (when you set in guiminer the card’s model, it sets by default intensity,…) when I tested it alone with the 2 others cards also connected to the motherboard. SO I guess these are correct. Are there any other settings I should use ?
              Thanks,

                  Hi,

                  I tested again make it works :)
                  But now I have a lot of HW. Or I have to set a very low intensity but my hashrate is below the one I can get with 2x5870 and 1x5770.
                  Any ideas ?

                  Thanks
