If you encounter the error message ‘AMDRyzenMasterDriver.sys cannot load on this device‘ on your Windows 11/10 PC, this post will help you resolve the issue.
AMDRyzenMasterDriver.sys is a system driver used by the AMD Ryzen Master utility to communicate with AMD Ryzen processors. When it is blocked from loading automatically, the following message often appears on screen:
A driver cannot load on this device
Driver: AMDRyzenMasterDriver.sysA security setting is detecting this as a vulnerable driver and is blocking it from loading. You’ll need to adjust your settings to load this driver
For most users, the error started after a recent Windows update because Microsoft now blocks older drivers that aren’t up to new security standards.
Why Windows blocks AMDRyzenMasterDriver.sys
With the introduction of Hypervisor-Protected Code Integrity (HVCI), also known as Memory Integrity, Windows’ security model has become stricter. It now blocks drivers that don’t meet modern validation standards. According to these standards, drivers must be built with specific security flags and digitally signed with approved certificates in order to load. Many older or unofficial drivers don’t meet these criteria and are therefore blocked.
AMDRyzenMasterDriver.sys cannot load on this device
To fix the error message, “AMDRyzenMasterDriver.sys cannot load on this device” in Windows 11/10, use these fixes:
- Check for Optional Windows Updates
- Update Ryzen Master
- Temporarily disable Memory Integrity
- Uninstall and reinstall Ryzen Master
Let us see this in detail.
1] Check for Optional Windows Updates
Microsoft often pushes driver compatibility fixes via Optional updates before including them in regular patches. These updates may resolve compatibility issues between older Ryzen Master versions and newer Windows builds.
Press Win + I to open the Settings app. In the left pane, click Windows Update. Scroll down and select Advanced options.
Click on Optional updates to expand the list. If you see any AMD or chipset-related updates (like Ryzen Master-compatible updates), check the box next to them and select Download & install.
Once the updates are installed, reboot the PC to apply the changes.
2] Update Ryzen Master
The error usually occurs because older versions of Ryzen Master include drivers that don’t meet modern Windows security standards. AMD’s updates may include digitally signed, HVCI-compliant versions of AMDRyzenMasterDriver.sys that are accepted by Windows 10/11 without triggering security blocks.
Ryzen Master includes a built-in update checker that automatically checks for updates every 15 days. You can also manually check for updates by launching Ryzen Master and navigating to Settings > Updates, then clicking the “Check for Updates” button. Alternatively, you can download the latest version manually from AMD’s official website or use the AMD Auto-Detect and Install Tool, which scans your system and suggests the appropriate drivers, including chipset drivers.
3] Temporarily disable Memory Integrity
Memory Integrity is a Windows security feature that blocks unsigned or improperly signed drivers from loading into memory, preventing malicious code from being injected into high-security processes. That is why some older or non-compliant drivers get blocked even if they are safe. Disabling Memory Integrity lowers the driver security enforcement, allowing the blocked AMDRyzenMasterDriver.sys to load.
To disable Memory Integrity, type ‘security’ in the Windows Search bar and select Windows Security from the search results. In the Windows Security app, click Device Security in the left pane and then click Core isolation details in the right pane.
Turn off the toggle for Memory integrity. Reboot your PC.
Note: Turning off Memory Integrity reduces system security, especially on Secured-Core PCs. Do this only if you trust the driver and need Ryzen Master functionality. Re-enable it once a compatible driver is available.

4] Uninstall and reinstall Ryzen Master
Uninstalling and reinstalling Ryzen Master helps ensure any corrupt, incomplete, or outdated installation is completely removed and replaced with the latest version. This helps resolve compatibility issues and allows the driver to load properly.
To uninstall Ryzen Master, type ‘control’ in the Windows Search bar and click Open next to Control Panel. Click Uninstall a program. Find AMD Ryzen Master in the list, right-click it, and select Uninstall. Follow the on-screen prompts to complete the process and then reboot your PC.
To reinstall Ryzen Master, visit the official AMD website using this link. You will see links to download the latest version of the software. Click Download Now and save the installer. Then run the downloaded setup file and follow the installation instructions.
Reboot again after installation to finalize driver registration.
This clean reinstall helps avoid conflicts between old drivers and newer Windows security policies.
I hope this helps.

Can I uninstall amdryzenmasterdriver sys?
You cannot directly uninstall AMDRyzenMasterDriver.sys like a regular app or driver via Control Panel or Device Manager. However, you can remove it safely from your system by uninstalling the AMD Ryzen Master application, which installs and uses this driver. If you delete the ‘.sys’ file manually from C:\Windows\System32\drivers, it might cause system instability or trigger integrity violations. Uninstalling the app is the correct and safe approach.
