Memory Integrity (also known as Hypervisor-protected Code Integrity, or HVCI) is a Windows security feature that uses hardware virtualization to protect your system's core from malicious code.
You do not need to enable this feature unless FACEIT Anti-Cheat specifically requires you to in order to continue playing.
How to Enable Memory Integrity
Open Windows Security: Press the Windows key, type Windows Security in the search bar, and hit Enter.
Navigate to Device Security: On the left-hand menu, click on Device security.
Access Core Isolation Details: Under the "Core isolation" section near the top, click the blue Core isolation details link.
Enable Memory Integrity: Find the Memory integrity toggle and switch it to On. (Note: This requires administrator privileges).
Restart Your PC: Reboot your computer to apply the changes. Once restarted, the FACEIT Anti-Cheat will recognize that HVCI is active.
Troubleshooting Common Errors
If you cannot enable Memory Integrity, it is almost always due to one of two reasons:
1. "Review Incompatible Drivers" Error
If the toggle is greyed out or won't switch on, Windows is blocking it because of older, incompatible drivers (often left over from old mouse, keyboard, or RGB software).
Click the Review incompatible drivers link right below the toggle.
Note the names of the drivers listed. You will need to update those specific devices via your manufacturer's website, or completely uninstall the associated software and drivers from your PC.
2. The Setting is Missing Entirely
Memory Integrity relies on your CPU's hardware virtualization. If you don't see the Core Isolation menu at all, virtualization is likely turned off in your motherboard's BIOS.
To resolve this, you will need to enable virtualization in your BIOS settings. Please follow our dedicated guide for step-by-step instructions: Enabling virtualization (Intel VT-x / AMD SVM).
