Q: Retina 5K - AMD Boot Camp Driver failure

I would like to begin a discussion of the Boot Camp Drivers for the AMD video card in the stock Retina 5K iMac.  There is a thread that demonstrates what appears to be a successful install of the drivers, and a thread that demonstrates a non-successful install.

 

A non-sucessful install looks like this:

ATI-bootcamp.JPG

The drivers tab indicates that driver version 14.200.1002.1002 is installed.

 

This is the stock Boot camp driver install.  The latest beta Catalyst drivers from the AMD website will also return the same results.

 

I have had conversations with Apple support and it seems there is no official support for Boot Camp after install.  They have no useful information beyond blaming Microsoft and/or AMD and acknowledging that there are threads at Apple communities that confirm people are having this issue.

 

For those of you with the Retina 5K, can you get the AMD Boot Camp drivers to function?  If so, what did you do to make it work?

Can you list your specific hardware load out?

 

I am not concerned about true 5K support in Windows, that is not the issue at this point.  The issue is that the AMD Boot Camp drivers will install, but Windows refuses to load them and returns a 'code 43' error.

 

Retina 5K - 3.5GHz i5, 8GB ram, AMD Radeon R9 M290X 2048MB

iMac (Retina 5K, 27-inch, Late 2014), OS X Yosemite (10.10)

A:

Solved!  Here is the solution. 

 

If you are installing Boot Camp Windows 8, 8.1, 10 (technical preview)  and in the Windows Device Manager you see an error (exclamation mark) next to the Display Adapter entry, and on the properties page a "Code 43" error is displayed, then the drivers provided by Boot Camp have failed to load and Windows is using a basic display driver that will not take advantage of the 3D acceleration capabilities of the video hardware.  Games, CAD applications, and etc. will not function as expected.  There are no drivers available as of this date that remedy this issue.  I've gone so far as to recompile driver packages and was never able to get past the Code 43 error.

 

The fix:

 

Forget Windows 8, 8.1, 10.  the Code 43 issue is not fixable using these version of Windows.

Install Windows 7.  That's it. Problem solved.  Code 43 did not appear on the first install of Windows 7, but was trivial to replicate when installing any other version.

Installing Windows 7 was more complicated than I counted on.  The basic Windows 7 install disc does not include bluetooth or USB 3.0 drivers. Boot Camp attempts to solve this by slip-streaming those drivers into the install. 

If you have any other USB device plugged into the iMac this slip-stream will fail.  Only your Windows USB and Boot Camp support USB should be plugged in.  In my case I have a USB mouse I prefer over the stock Apple mouse.  This prevented the Bluetooth drivers from activating and I was stuck at the language selection screen of the install with no mouse or keyboard.  Plugging in a wired mouse and keyboard did not solve this issue.  Neither did disabling bluetooth in OSX and trying the install again.

I also encountered an issue where after creating the Boot Camp partition, when the computer would reboot to start the Windows install, I would get a "No bootable device" error and a full computer stop.  If I held down Option when rebooting I could select the Windows USB as the boot device and the install would start, but the needed drivers would not load.  The only way I found to fix this was to reboot into OSX, open Boot Camp Assistant and remove the Windows partition, exit Boot Camp Assistant, open BCA again and recreate the partition, then reboot.  Then do this over and over and over (and over, and over, and over again) until it didn't give me this error.  It took 8 tries for the computer to find the Windows boot drive on its own.  Option, then selecting the Windows USB never worked.  /usr/sbin/bless did not work.  I had to delete the partition and recreate it with BCA, then reboot.

 

There are 192 updates to Windows 7 SP1 with a stock installation.  It took 2.5 hours to complete the updates. I've tested the video hardware before and after the updates and can confirm the Code 43 error is not evident in my Windows 7 Boot Camp install, and 3D hardware and drivers are functioning as expected.

    I used W8.1 64-bit Full Retail edition which comes with a separate key. I had to manually run setup.exe from Bootcamp folder. The only drivers that were already there were Broadcom BT/Wireless (which are in the $WinPEDriver$ folder).

     

    In my case, before the BC Drivers, I have a generic display adapter, while you seem to get the R290 before and after, both. The before and after also has Audio device differences.

     

    Which exact version of Windows are you using?

    This is crazy as I'm only able to install the stock bootcamp drivers which support my R9 295X but i'm unable to install any of the beta drivers from AMD's website.

    Loner T, sorry to jump onto the discussion between you and Novelty but i'm using Win 8.1 Pro and windows only seems to detect my display adapter as Microsoft Basic Display Adapter and not R290 series. I can only install the stock drivers for my R295X but I then can't update the drivers with any of the beta drivers. Also if I try downloading the AMD beta drivers and attempt to do a manual install by running the setup from the Drivers/Display/WB6A_INF folder I get an unknown error has occurred when Catalyst Install Manager loads up during the Analyzing process before installation.

     

    Any suggestions?

    I'm using Windows 8.1 64bit full retail as downloaded from Microsoft.  The bootcamp drivers for all devices are always fully installed if I allow the bootcamp process to complete.

    The only difference between your diskutil list is my hard drive is encrypted.

    No worries. We are all trying to get a working setup for all potential 5K owners. All input/discussion is very helpful. In my case, The 'before' is a Generic display adapter, but when the BC drivers are installed, the R290 comes up, similar to your case. I downloaded the 14.9 from the nVidia website which gave me the 14.3 driver and updated Catalyst control panel. The R295 should at least allow the non-Beta driver to install. I will try a R295 test.

     

    Also if I try downloading the AMD beta drivers and attempt to do a manual install by running the setup from the Drivers/Display/WB6A_INF folder I get an unknown error has occurred when Catalyst Install Manager loads up during the Analyzing process before installation.

     

    Any suggestions?

    Unless you absolutely must have the Beta driver, my suggestion is to use the latest non-Beta (aka the GA - Generally Available) driver. If that has installation issues, nVidia and the community can put their heads together for some investigation.

    If you are using Apple FV2, you will get a CS volume. In my case it is a CS volume, but unencrypted. The BC partition is independent and should not be touched by FV2. As a test, you can turn it off and redo your AMD installation only, not the Windows re-installation.

    You can try ATI drivers from BootCamp5.1.5766, this working for me. https://www.dropbox.com/s/qw7tnb8897drkzv/ATIGraphics.zip?dl=0

    Thanks for the suggestion and drivers to try.  Without even trying them I can tell you they won't work.  Looking through the files in the driver package I see it is the stock driver version released with BootCamp 5766.  AMD driver version 14.200.1002.1002 which is the version I have been having issues with.

    I just want to tag this thread.  I'm experiencing the exact same issue as Porkstar.  I can install the included Apple Boot Camp AMD R295X driver, and it is recognized by my Windows 8.1 Pro install.  However, any attempt to update to AMD's latest or beta drivers fails.  I'm thinking that the work done for Apple's Boot Camp driver hasn't been rolled into AMD's public release/beta development branch, and AMD's latest installer just doesn't recognize or support these newer AMD R295X cards--purely speculation on my part though.

    People getting the Omega drivers to work via the linked hack are Mac Pro owners.  Those of with R5K machines are reporting significant issues with that method.  It looks interesting enough to try though.  Maybe this weekend when I have some time. 

     

    Thanks for the link.

    Does not work for Retina iMac.  'Code 43' error continues to be the issue.

    I do not know English. Sorry for the short post.

    There was no problem with the old iMac graphics card nvidia drivers update.

    Who is the source of the problem? apple or amd?

    I got to play my new machine. This problem is too big for me.

    I am very angry.

    Are there any specific reasons why the Apple/Bootcamp driver is not sufficient for your needs?

    because the new drive offers 20-30% more performance. This is a very important value. (windows 8.1)

    also offers a graphic presets for the games.

    AMD automatic detection software found my r9 m295x card. but indicates that support this card. This is ridiculous.

    There is no support, why are you selling?

    apple, should provide us with new drivers.
