How to fix FACEIT Please enable Memory Integrity to continue
This means FACEIT requires Windows Memory Integrity and yours is off, so you cannot connect. Turning it on fixes it, though it needs virtualization enabled first. Jump to your situation below or work through the methods in order.

Error message
Please enable Memory Integrity to continue.
Summary
Some FACEIT players are required to enable Memory Integrity (also called Core Isolation Memory Integrity, or HVCI) as an extra anti-cheat measure. The fix is to turn it on in Windows Security, Device Security, Core Isolation, then restart. Memory Integrity relies on hardware virtualization, so if the toggle is greyed out or missing, enable Virtualization in your BIOS (Intel VT-x / AMD SVM, and VT-d / IOMMU if present) and it will become available. A common blocker is an incompatible driver: Windows will refuse to switch Memory Integrity on and may point to a driver that must be updated or removed first. If enabling it causes instability, FACEIT recommends running Windows Update, removing old or incompatible anti-cheat software, and updating your motherboard BIOS. Because this is a required security setting rather than a ban, enabling Memory Integrity lets you connect.
What this error means
Memory Integrity (Core Isolation, HVCI) uses virtualization to protect the Windows kernel from malicious drivers. FACEIT requires some players to enable it as an anti-cheat measure. The error means it is off, and you cannot connect until it is on.
Enabling it in Windows Security Core Isolation fixes it, but it needs virtualization enabled in BIOS to be available, and an incompatible driver can block it from turning on. Windows Update, removing old anti-cheat and a BIOS update resolve instability after enabling it.
Common causes
Memory Integrity is turned off in Windows Security.
Hardware virtualization is disabled in BIOS (toggle greyed out).
An incompatible driver is blocking Memory Integrity.
Old anti-cheat software or an out-of-date BIOS causing instability.
Expert insight
“Memory Integrity trips people because the toggle is often greyed out, and that is almost always virtualization being off in the BIOS, so turn on VT-x or SVM and it lights up. The other blocker is an incompatible driver, Windows will name it and refuse to enable until you update or remove it. Enable it in Core Isolation, restart, and you are in. If the machine gets unstable afterwards, FACEIT's own advice is run Windows Update, pull any old anti-cheat, and update the BIOS.”

✓ How to fix it
Method 1
Enable Memory Integrity in Core Isolation
1Open Windows Security, Device Security, Core Isolation and turn on Memory Integrity.
2Restart when prompted.
3Relaunch FACEIT.
Method 2
Enable virtualization if it is greyed out
1If Memory Integrity is greyed out or missing, enable Virtualization in BIOS (Intel VT-x / AMD SVM, plus VT-d / IOMMU if present).
2Save and reboot.
3Turn Memory Integrity on.
Method 3
Update or remove a blocking driver
1If Windows refuses to enable it and names an incompatible driver, update that driver.
2If no update exists, uninstall the device or software.
3Then enable Memory Integrity and restart.
Method 4
Fix instability after enabling
1If the PC becomes unstable, run Windows Update fully.
2Remove old or incompatible anti-cheat software, and update your motherboard BIOS.
3Restart and test.
For FACEIT Please enable Memory Integrity to continue, turn on Memory Integrity in Windows Security, Device Security, Core Isolation, then restart. If the toggle is greyed out, enable virtualization (Intel VT-x / AMD SVM) in BIOS. Update or remove any incompatible driver blocking it, and if you get instability, run Windows Update, remove old anti-cheat, and update the BIOS.
Frequently asked questions
Why does FACEIT require Memory Integrity?
Memory Integrity (Core Isolation, HVCI) uses virtualization to protect the Windows kernel from malicious drivers. FACEIT requires some players to enable it as an added anti-cheat measure against driver-based cheats.
How do I enable Memory Integrity?
Open Windows Security, go to Device Security, Core Isolation, and turn on Memory Integrity, then restart. If the toggle is greyed out, enable virtualization (Intel VT-x or AMD SVM) in your BIOS first.
Why is Memory Integrity greyed out?
Memory Integrity needs hardware virtualization, so if it is greyed out or missing, virtualization is disabled in your BIOS. Enable Intel VT-x or AMD SVM (and VT-d or IOMMU if present), reboot, and the toggle becomes available.
Memory Integrity will not turn on, why?
An incompatible driver is usually blocking it. Windows names the driver when it refuses. Update that driver, or uninstall the device or software if no update exists, then enable Memory Integrity and restart.
My PC is unstable after enabling it, what do I do?
FACEIT recommends running Windows Update fully, removing old or incompatible anti-cheat software, and updating your motherboard BIOS. These resolve most instability caused by enabling Memory Integrity on older configurations.
Is Memory Integrity the same as Core Isolation?
Memory Integrity is a feature within Core Isolation in Windows Security, sometimes called HVCI. FACEIT's error refers to this specific toggle, which you turn on under Device Security, Core Isolation.
Still not working?
If Memory Integrity still will not enable after updating drivers and virtualization, use the Windows Security scan for incompatible drivers to list every blocker, then update or remove each one before trying again. You can also submit your error to us for a tailored fix.
