Good news, I downloaded the 8.12 drivers from Diamondmm website, which is the brand of the two 3870 I have, I installed them OVER the DNA 8.11 and everything works great after the reboot. No error in Device manager, crossfire was disabled after the install and had to reboot to enable it agian. So people who are having trouble with crossfire, download the drivers from your brand of card and see if those work just like mine did. Also, if that doesn't work, try disabling crossfire before you install again. Edit: Okay, thats strange, on the reboot it showed crossfire was working, then all of a sudden few minutes later it disappeared. urgh!! Edit2: Well once I install them, device manager says the graphics card is working properly. I see crossfire in CCC but I can't enable it. If I reboot, I believe I will get the code 43 again on second gpu. I'm going to install an older CCC to see something. Edit3: I uninstalled the 8.12 CCC left the display drivers, installed the 8.11 CCC, rebooted and got no errors in device manager. Going to enable crossfire in CCC right now lets see if this will disable my second gpu and give me code 43.................I heard the normal da da noise, once screen got back it disabled my GPU and got code 43. SOOOOOOOOOOO... Doesn't look like these 8.12 drivers like being crossfired. So now, I'm back to DNA 8.11 w/ no CCC , using ATT instead.
