    Hi guys,

    i'm currently really frustrated because my Windows 8.1 doesn't work on my new iMac. To be more precise everything work but I cannot get my graphic Card (AMD Radeon R9 200) to work with Windows.

    I'm always getting the error message in the device Manager "Windows has stopped this device because it has reported Problems (Code 43)".

    I nearly tried everything: Installing the original boot camp Driver, installing the newest amd beta Driver, reinstalling Windows 8.1...I have no idea what else I can try... :-(

    Today I had a call with the apple Support and they told me that this is a known issue because amd don't Support the 5k Display with the Driver.

    But I already asked Google and couldn't find anyone else with this issue. The Driver seems to work for everyone but me :-(

    Does anyone have an idea what else I could try to fix this Problem? I only want to Play games in windows and it didn't work because of this Driver issue...

    Thanks für your help,

    you mean the amd m290x in the imac?

    it works with the amd m295x with the new imac 5k but a week ago the frame rate dropped in half for wow so even it was faster than on os x, it's now slower.

    I've got 8.1 running Bootcamp on my RiMac with the base GPU like you.

    I have had no similar problems, as far as I know it works ok. I'll check the settings next time I boot it up.

    The only display issues I have had are around scaling of fonts and program windows being very small. I'm new to mac so not sure what I'm doing yet. I don't know if that is a software thing or me being incompetent!

    Yes, the m290x! I simply cannot play anything because Windows deactivates my GPU :-(


    This "display issue" is normal. I have this issue too.

    So far as I know I'm the only one with this massiv driver issue. First I though maybe the graphic card is defect but in OS X everything works quite well...

    So what are we saying. It works with the 295. But not with the 290???

    note that for a week or so the m295x under win8.1 is very slow, at least when playing wow. before I has 90 fps with 4k, now only 30 but without the fan noise. I'm not sure if it is related to your issue or just a wow bug where people complain about low frame rates. doesn't happen to me on mac os x though. be prepared to wait for a long time before this is fixed.

    I've had iMac Retina's with both the M290X and the M295X and I've not experienced any driver issues.

    For both cards the drivers applied fine from the bootcamp install USB.

    I've also tried the ones downloaded from AMD with no issue.

    I'm using a reasonably recent copy of Windows 8.1 Enterprise download from the volume licensing center.

    Today I tried a complete and fresh reinstall of the whole system (including a clean Yosemite and Win 8.1 Pro x64 Installation)...simply the same problem. Windows shuts down my graphic card (probably) because of driver issues...

    I really have no further ideas how i can solve this problem. Later I will try to get it to work with my old win7 image. Maybe it has something to do with the .iso? Really frustrating :-(

    Hi. Did you ever resolve this issue? I have the exact same problem and I'm tearing my hair out! Tried everything.

    I've been on to Apple and Microsoft support and they keep telling me to speak to the other company.

    I'm really close to returning my iMac.

    Just on the off chance, go into Programs and Features, then into Turn Windows Features on or off, and check that Hyper-V is not install, if it is installed then remove it. I have had issues with bootcamp graphic drivers in the past and Hyper-V. Its worth checking.

    I've got the same problem with a brand new 5k iMac.

    The ATI driver installs and then next boot it throws the error.

    Has anyone got a fix? This is incredibly frustrating.

    Trying it again now. Just going down for a reboot.
    This will be the 3rd time on a fresh install of Windows 8.1.

    Will update you in a tick.


    Nope, no luck.
    Error when launching Catalyst Control Centre - No AMD graphics driver is installed.
    Error in Device Manager stating Windows has stopped the device because it reported problems (Code 43)

    Trying a manual install of the driver linked above now rather than using the wizard.

    Edit: Results in same problem

    Even installing the driver that is supplied with Bootcamp results in the same problem.

    I've got to get this PC ready for tomorrow.

    How do you know the device is not defective?

    No problems in Windows 7 or MacOS.

    There's the same problem over on the Apple discussion forum. I think some people from here have contributed to that discussion.

    I'll upgrade the client to Windows 8.1 when a new driver is released and there is sufficient evidence to show it that it works without any hassle.
