Since Windows 10 version 1803, and continuing in Windows 11, Microsoft has implemented stricter kernel-level driver validation through security features like Hypervisor-Protected Code Integrity (HVCI), which is managed under Memory Integrity in the Windows Security app. HVCI enforces that all kernel-mode drivers must be compiled with specific security flags and signed using a compatible Hardware Security Test Certificate. Drivers that do not meet these criteria—such as legacy or outdated versions of Ryzen Master—are blocked from loading. When this occurs, you may see Event ID 7000 in the System log, along with a notification saying “A driver cannot load on this device.” In addition to HVCI, this error can occur if your AMD Ryzen Master Utility is not updated. Versions released before Microsoft’s 2023 driver attestation enforcement deadline may not pass the latest compatibility checks. Although this issue typically does not impact system stability, running an outdated driver might prevent Ryzen Master from launching or working correctly. Fortunately, the issue can usually be resolved with a few straightforward fixes. We’ve outlined several proven methods below, based on official AMD support guidance and Windows documentation.
Solution 1. Reinstalling AMD Ryzen Master Utility Software
One of the most effective ways to fix the “AMDRyzenMasterDriver.sys – A driver cannot load on this device” error is to fully uninstall and then reinstall the AMD Ryzen Master Utility. This error can occur if:
The software installation has become corrupted.An older version is installed that is incompatible with newer Windows kernel security features like Memory Integrity (HVCI).
Reinstalling Ryzen Master ensures that the driver is replaced with a fresh, updated version that’s properly signed and compatible with Windows 10/11 kernel-mode enforcement policies. Follow the steps below carefully.
Solution 2. Disabling Core Isolation (Memory Integrity)
Core Isolation is a Windows security feature that uses virtualization-based security (VBS) to isolate critical system processes from malicious or untrusted drivers. One of its components, Memory Integrity, blocks unsigned or improperly signed kernel-mode drivers from loading — including older versions of the AMD Ryzen Master driver (AMDRyzenMasterDriver.sys). If you’ve already updated Ryzen Master but the driver is still being blocked, temporarily disabling Memory Integrity can allow the driver to load correctly. This is useful for testing compatibility or as a short-term workaround until AMD releases a fully compliant driver update. As of now, users must wait for AMD to publish an HVCI-compliant version of AMDRyzenMasterDriver.sys to use Ryzen Master fully while keeping Memory Integrity enabled. You can monitor AMD’s support site for the latest release notes and version updates. Tip: You can confirm Memory Integrity is blocking the driver by checking the Windows Event Viewer for Event ID 7000 or error codes like STATUS_INVALID_IMAGE_HASH after reboots.
