Drivers will not install with crossfire

Shining_KoW210 · Mar 20, 2013

My problem is when I have both of my graphics cards plugged in, I try to install the graphics drivers, but then it goes to a blank screen and I have to force restart, and it won't go past the windows loading screen, I have to remove the second graphics card to continue. I have tried the latest stable drivers and the new beta drivers. I have completely uninstalled the drivers, via safemode and I even used Driver Fusion to make sure that they were gone. Each card works fine individually. I don't know what else to do.

Okay here's my DXDIAG.

Try getting it working with one card then add the other once the first one works.

I already tried it. I got the drivers to install with only one card in. If I turn off the computer and put back in the second one, it'll go as far as the Windows loading screen, then to a black screen that never ends.

What, specifically, are your specs?

It's in my DXDiag....

I have 2 Radeon HD 6870's
AMD FX 8120
Asus M5A97 EVO

And your psu? This can be caused by not enough power.

Ok that is a quite beefy psu... Well your motherboard's pci express slots are 16x and 4x this will limit your bandwith but I don't think it would cause this problem. Do both cards work independently?

Shining_KoW210 · Mar 20, 2013

ikes9711 :

Yes they both work individually, I can switch one for the other and they will both work fine. They just don't work together.

ikes9711 · Mar 20, 2013

Then the only thing I could think of is your motherboard not having enough bandwith to support crossfire.

Shining_KoW210 · Mar 20, 2013

It worked for 8 months, I don't see why it's not working now. Could there be a physical problem with the motherboard? I've considered getting it RMAed, I just wanted to be sure there was nothing else I could do.

Also are you overclocking your cpu. If your settings are too high your board may stop displaying

ikes9711 · Mar 20, 2013

It also just may be hardware decay. All your setup and specs are good.

Shining_KoW210 · Mar 20, 2013

Yes I am overclocking, the temps are low, and I've OCed for months now. I'll try removing the overclock and see if that fixes it. If it doesn't, would you recommend that I RMA it?

ikes9711 · Mar 20, 2013

Sadly it might be the solution.

Shining_KoW210 · Mar 20, 2013

I removed the OC, and it allowed me to log into Windows with both of my cards attacted, only problem was, only one of my monitors was on, the other two, it didn't recognize. So I tried to install the drivers again, and it yet again black screened.

I'll try do what the person above this said.

How do I disable ULPS?

Okay so I tried the solution above and the same thing happens. During the installation of the driver my screen turns black and freezes.
