Windows Update Causing Crossfire Issues

The update Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3147458)
is causing my AMD crossfire to stop working. I have tested on the games Planetside 2, Skyrim, and Devil May Cry. In all of these games the audio works but the screen is black. Disabling crossfire fixes the issue. All of these games are 32 bit and DX9
(Planetside 2 current version is 64 bit but was originally 32 bit).

It appears that even being in the install queue breaks crossfire. The only way to fix the issue is to install the update, uninstall the update, and then reinstall AMD drivers using Display Driver Uninstaller.

I've tried reinstalling AMD drivers and resenting/reinstalling Windows but the above is the only way I've found to fix the issue.

Any suggestions for fixing this problem?

Computer Specs:

8Gbs RAM

Gigabyte 990FX Mobo

2x AMD 7870 OC

AMD 8350 OC 4.4Ghz

 

AMD FX OC'ers Club

That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.

now we just wait on ATI/AMD, since at least they'll be aware of the issue

(any crossfire users on P55 or x58, please step up!)
