Crossfire issues- Games won't start

[Revelationgaming]

Like the title says. When I click on any game to run, I immediately BSOD. This happened after putting in a second 7950, so it's not an issue with anything else but crossfire.

Kind of sounds like a power issue to me, what's your power supply? I have almost the same build as you and I have ne problems with crossfire (6300, 2X 7950).

750watt kingwin maximum series PSU. Its served me well so far. Also, I dont know why it would do it when running the game itself rather than starting an actual game where the graphics cards are under stress

Maybe it's a driver error. Did you try re-installing your drivers or getting the latest beta driver from AMD's website? Also, have you overclocked your CPU or graphics cards? The overclock may be unstable and causing errors when you start a game.

What are the games are they supported by Crossfire?

Yes I have over clocked. However I just realized that the voltage I put both cards at was slightly lower than my sapphire's voltage. In msi afterburner, is there a way to overclock each card with different voltages and the same clock separately while both are hooked up?
Also, I couldn't even get afterburner to work properly. After I clicked apply the bars would reset to zero for some reason. Is that just a glitch when using crossfire?

Anything. Bf4, CSGO, even furmark caused the blue screen

I really haven't tried overclocking using crossfire yet, however you should probably take the side panel off of your case and look right next to the crossfire fingers on your graphics card. You should see a little switch with settings 1 or 2 on watch of your GPU's. Switch it to position 2 on both cards to reset the cards to factory standards. See if that fixes your games.

Switch should look something like this: Switch

Reset it, but still won't work.

Just tried it with no success

NVM I fixed it. I don't, unfortunately know whose solution fixed it lol. I tried undervolting my sapphire and that seemed to work.

take out the bottom card use driver sweeper to erase all amd vga drivers then reinstall with one card in after its all cool re install second card do it in this order
