Mac Pro (Late 2013), Windows 8
open device manager, expand display adapters in windows and post a screen shot
did you install windows with boot camp or another method
are you using stock boot camp drivers or other ones
I use the stock boot driver and no other . Here are the FirePro controlcenter :
Strange, I show both
How did you install windows and did you update the amd drivers manually
Mac Pro does not support Crossfire under OSX or Windows. Only one GPU is used for all displays, the second is reserved for OpenCL.
Thats right i now osx doesn't Support crossfire ! I Talk about windows\bootcamp and The Screenshots are from windows 8.1
First sorry for my english i came from Germany ;) I made a normal install with an win 8.1 Image on USB Drive with The lastest bootcamp driver ! After The install completed i Start The bootcamp setup and restart The System .
this is incorrect. crossfire IS supported under boot camp / windows, just not osx

ok, so you used standard boot camp drivers
restart the machine and run windows update
you will likely have to restart again and check now
You - or someone else? on MacRumors:
New Mac Pro 2013 crossfire disabled
Latest beta driver, and not sure if people are using FirePro or another series.
With two GPUs standard in every Mac Pro configuration, there’s obviously OS support for the configuration. Under Windows, that amounts to basic CrossFire X support. Apple’s Boot Camp drivers ship with CFX support, and you can download the latest Catalyst drivers directly from AMD and enable CFX under Windows as well. I did the latter and found that despite the option being there I couldn’t actually disable CrossFire X under Windows. Disabling CFX would drop power consumption, but I didn't always see a corresponding decrease in performance.

Nothing helps me , i loved to returned a new product to Apple to get some refurbished .
Any Ideas out there , it looks like an error with the GPU Interface ......
you can always try deleting and re-installing windows, unsure if it will work but if so, better than the lost time trying to get a warranty repair
Thank you for your Time ! After Several new installations, try Different driver , search in Forums i made a Point .
I think it is better that i contact Apple for The warranty .

About crossfire in windows? There is no apple documentation but there are 10s of not 100s of people now who have done various benchmarks and tests showing it working in windows. Google around.
