Install AMD GPU drivers on N-series VMs running Windows
To take advantage of the GPU capabilities of the new Azure NVv4 series VMs running Windows, AMD GPU drivers must be installed. The AMD GPU Driver Extension installs AMD GPU drivers on a NVv4-series VM. Install or manage the extension using the Azure portal or tools such as Azure PowerShell or Azure Resource Manager templates. See the AMD GPU Driver Extension documentation for supported operating systems and deployment steps.
If you choose to install AMD GPU drivers manually, this article provides supported operating systems, drivers, and installation and verification steps.
Only GPU drivers published by Microsoft are supported on NVv4 VMs. Please DO NOT install GPU drivers from any other source.
For basic specs, storage capacities, and disk details, see GPU Windows VM sizes.
Supported operating systems and drivers
|Windows 10 Enterprise multi-session - Build 1909
Windows 10 - Build 1909
Windows Server 2016
Windows Server 2019
If you use build 1903/1909 then you may need to update the following group policy for optimal performance. These changes are not needed for any other Windows builds.
[Computer Configuration->Policies->Windows Settings->Administrative Templates->Windows Components->Remote Desktop Services->Remote Desktop Session Host->Remote Session Environment], set the Policy [Use WDDM graphics display driver for Remote Desktop Connections] to Disabled.
Connect by Remote Desktop to each NVv4-series VM.
If you need to uninstall the previous driver version then download the AMD cleanup utility here Please do not use the utility that comes with the previous version of the driver.
Download and install the latest driver.
Reboot the VM.
Verify driver installation
You can verify driver installation in Device Manager. The following example shows successful configuration of the Radeon Instinct MI25 card on an Azure NVv4 VM.
You can use dxdiag to verify the GPU display properties including the video RAM. The following example shows a 1/2 partition of the Radeon Instinct MI25 card on an Azure NVv4 VM.
If you are running Windows 10 build 1903 or higher then dxdiag will show no information in the 'Display' tab. Please use the 'Save All Information' option at the bottom and the output file will show the information related to AMD MI25 GPU.
