Hi All, made a thread a while ago about instructions in forcing AMD drivers to update on bootcamp systems. Here's an updated guide with what I've learned. A lot of the steps previously required are extraneous so I've attempted to simplify it. The hardest part in my troubleshooting was maintaining Catalyst Control Panel (or in my case FirePro Control Panel) functionality . Following this order of updates seems to work very reliably in getting myself to the latest 16.3.1 drivers released today. I've never been able to get this working on Windows 10 (seeing cards labeled incorrectly in Catalyst Control panel, the control panel disappearing and failing to reinstall, and consistant crashing were all issues I faced in my experimenting). With 16.3.1 released today I'll update later to Windows 10 to try again and see if I can get success. I would really like to be able to utilize DX12. I've found two great sources of already modified drivers. https://www.media-xtreme.net/ http://www.remkoweijnen.nl/blog/2015/09/21/update-amd-display-driver-under-bootcamp/ I prefer personally to modify the drivers myself to ensure security, but shout outs to these guys for doing what they do. Here's how I do it. Step 1. Use DDU to uninstall all sources of AMD drivers. Step 2. Boot into OSX and download the latest Bootcamp drivers from Apple using Bootcamp Assistant. These AMD drivers are newer than what's offered on AMD's website. Step 3. Boot into Windows and navigate to your newly downloaded Bootcamp driver folder. Specifically /Bootcamp/Drivers/AMD/AMDGraphics/Setup.exe Step 4. Install these and restart. I've found installing these first ensures that FirePro Control Center stays functional throughout the next few steps. You may find it's not necessary but it works for me. Step 4. Download both the 15.12 Crimson WHQL drivers and the 16.3.1 Crimson Hotfix drivers from AMD. Step 5. Running both exe's will extract their contents to C:\AMD\ They'll fail, but the files you need will be extracted. Step 6. Navigate to C:\AMD\Radeon-Crimson-15.12-Win8.1-64Bit\Config\InstallManager.cfg and open with notepad. Add the line EnableFalcon=True This will force the installer to run. Step 7. Navigate to C:\AMD\Radeon-Crimson-15.12-Win8.1-64Bit\Packages\Drivers\Display\ and open the CU296876.inf file in Notepad. Step 8. All the guides I've read in the past required finding your hardware ID from Device Manager and modifying files to specifically include your cards. I've found a universal way that's much easier that will work with all cards that I've tested with. Use "Find" and look for any entires with the word "Exclude" in it. Delete every single exclude entry after the first result. These are the settings that block Mac AMD card hardware ID's from receiving the updates and other cards as well. Step 9. http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/ Using this guide, disable Driver Signature verification. This will allow you to install the now modified drivers without the need to sign them your self. Step 10. Install driver, click yes on any prompts. You should restart and find yourself with a fully working Crimson Control Panel. Your cards may be labeled differently, but as long as they are both labeled the same Crossfire will work perfectly. Step 11. Repeat above steps on the 16.3.1 drivers. Adding EnableFalcon=True and deleting all "exclude" entries from all three .inf files located in the \Packages\Drivers\Display folder in the same way you did for the 15.12 drivers. Step 12. Disable Driver Signature Verification one last time and install the drivers. Step 13. Profit? If you have any questions let me know. I'm guessing you could use the modified drivers above to achieve the same effect but I've always done it my own way. I'll add an update if I can get it working on Windows 10.
