mXDriver Howto

The following should help all folks who are new to mXDriver. There is an old installation method which is not needed any more (since mXDriver 16.9.1 Reloaded) but if you want/need to install older versions of mXDriver the old method is still valid. Please read the Howto carefully as forgetting something or making mistakes will end up in a unsuccessful installation of mXDriver. If you have problems although you worked completely and correctly through this Howto please see the FAQ or post in the comments section of the regarding driver release.

Installing mXDriver is pretty straightforward just follow the instructions below. These are for mXDriver 16.9.1 Reloaded and above. For older releases until mXDriver 16.9.1 please see the old installation method below.

  1. Uninstall the old AMD driver completely. Best is to use current version of Display Driver Uninstaller (DDU)!
  2. If not yet installed, install the Code Signing Certificate of (mXDriver.com_Code_Certificate.cer) which can be found in the driver’s root folder where THIS README.TXT is also found.
  3. Double-click on the certificate.
  4. Press button “Install Certificate”.
  5. Choose “Local Machine” as Store Location and press Next.
  6. Choose “Place all certificates in the following store” and select “Trusted Root Certification Authorities” via the Browse button.
  7. Press finish and a message should appear that the import was successful.
  8. Reboot the system.
  9. Start the installation of the driver by opening the Setup file.
  10. Choose the parts you want to install.
  11. At some point a window should appear asking you if you trust the publisher “ Code Certificate”, you need to select “Install” otherwise the driver won’t be installed.
  12. When the installation is finished it should read that “…software and drivers have successfully been installed.”
  13. Uncheck “Automatically download latest drivers”.
  14. Restart the system and enjoy the driver!

ARCHIVE: Old Installation Method

  1. Hi, I’m desperate to resolve my driver issue under bootcamp Windows 10. I followed your instruction but got lost with step 4. how to install it, I know it is under device manager update driver and locate the driver then install. But no inf file inside the folder WT6A_INF. Am I missing something please help.

  2. Further instruction much appreciated. Thanks

    • I am also having problems here. I think this Retina may be a problem for Windows drivers

  3. Hi,

    Is it possible to deactivate testsigning and enable driver signature after the driver has been successfully installed? Thanks!

  4. Do I have to un-install the previous mXDriver, or will the latest mxDriver overwrite it? Thx.

  5. Hi, excuse my ignorance but will I be able to get better performance from my dual D700 on my mac pro running Windows? Mainly for playing games.

    • If you turn off testsigning Windows will unload the driver. So no, if you want to use mXDriver you need to keep testsigning turned on.

  6. Hey Joe!
    Hope all is well,
    I get about 14% of the way into the installation and it hangs and gives me “AMD install manager has stopped working”

  7. Hello,
    I use your drivers since quiet a long time now on my mac pro (Firepro D700)

    The problem actually is that lot of people take your drivers for gaming.
    But !
    Few games are using battleye anti-cheat that don’t allow to lunch games in Windows 10 Testing mode.
    The thing is that the official bootcamp drivers, as you know : Are really bad !!!

    Some games with DX12 support are getting better performances and even, crossfire support (wich is nice for a mac pro with dual D700)
    So I hope and I thing, its really the time for you to find a solution with this test mode problem.

    I Prefer 1000x your drivers, each time I used it, the games were working just a lot better than with the official bootcamp drivers: better framerates, more stability…

    And now, in order to play I have to use the crapy official drivers.
    Please find a solution, sign your drivers or tell us how to use it in normal mode even if we have to work hard to do that ^^

  8. After installing these drivers a few weeks ago, I noticed a big boost in performance with D700’s. I get 170 fps in Black Ops 3 which is great.

    However, I am not sure if the drivers are fully compatible / bug free, for example, if I create a profile for Black Ops 3 and enable frame cap of 144 in the AMD driver control panel (to match my monitor and not overwork the machine) and test the game, it does cap the framerate to 144. If I then disable the profile so it uses global settings instead then the frame cap is still in place when I run the game so it ignores that I disabled the profile and still uses it. O.o

    If I delete the profile (rather than disable it) then the frame cap is ignored as expected.
    Could be a bug in the control panel?

    Also, in case anybody else was wondering, the Dxxx cards are NOT FREESYNC compatible as I have now tested this.

  9. I can’t start the windows partition in Boot Camp after installing 16.11.4. Any suggestions on fixes?

  10. The Installer gives me error 182 “Installer cannot properly identify the AMD graphics hardware” right at the start. I did everything the guide says. I have a Mac Pro with 2x D300s. Can anyone help me with this? THX

  11. Hi alls, i’ve bought assassin’s creed origns but it don’t want launch (mbp 2017 amd radeon pro 560)
