RTX Configuration 2 - Critical System Settings¶
The following settings must be applied for stable RTX operation.
Disable Windows Memory Diagnostics
If you run RTX for an extended period on Windows 10 or Windows 11 with Windows Memory Diagnostics enabled, a memory access violation may occur and trigger a blue screen, causing the PC to restart.
Windows Memory Diagnostics should be disabled to prevent Windows from unpredictably compressing or moving memory.
To disable Windows Memory Diagnostics, follow these steps.
Search for “Task Scheduler” from the Windows Start Menu and run it.
In the left pane, expand Task Scheduler Library\Microsoft\Windows\MemoryDiagnostic.
In the center pane, right-click the RunFullMemoryDiagnostic entry and select Disable.
Similarly, right-click the ProcessMemoryDiagnosticEvents entry and select Disable.
Restart the PC.
For additional information, please refer to the following technical note of IntervalZero (the developer of RTX).
Disable Hyper-V
When you start RTX on Windows 10 or Windows 11 with Hyper-V enabled, a blue screen will occur and the PC will restart. Hyper-V must be disabled. Follow the steps below to disable Hyper-V.
Search for “Turn Windows features on or off” from the Windows Start Menu and run it.
Uncheck “Hyper-V”.
Restart the PC.
For additional information, please refer to the following technical note of IntervalZero (the developer of RTX).
Disable Virtualization-Based Security (Credential Guard, Memory Integrity)
Virtualization-Based Security is a dedicated feature of Windows 10 Enterprise or Windows 11 Enterprise, consisting mainly of Memory Integrity (formerly known as Device Guard) and Credential Guard.
When virtualization-based security is enabled, issues such as the RTX installer returning errors or a blue screen occurring when launching RTX may arise.
Virtualization-Based Security must be disabled.
Virtualization-Based Security is automatically disabled by disabling Hyper-V as mentioned earlier, but in some Windows versions, configuration via Group Policy may be required.
To disable virtualization-based security in Group Policy, follow these steps.
Press the Windows key + R key, type “gpedit.msc” to launch the Local Group Policy Editor.
Open [Computer Configuration] - [Administrative Templates] - [System] - [Device Guard] in the Group Policy settings screen.
Set the following items to “Disabled”. The names and number of setting items may vary depending on the Windows version. Basically, disable all items.
Deploy Code Integrity Policy
Deploy Windows Defender Application Control
Turn On Virtualization Based Security

Disable Fast Startup
If the RTX Startup Type is set to Automatic, the Windows Fast Startup option must be disabled.
To disable Fast Startup on Windows 10 or Windows 11, select Power Options in the Control Panel. In the “Choose what the power buttons do” tab, click on “Change settings that are currently unavailable” and uncheck the “Turn on fast startup” option.
For additional information, please refer to the following technical note of IntervalZero (the developer of RTX).
Disable x2APIC mode
On Windows 10 or Windows 11 with x2APIC mode enabled, issues may occur such as the RTX subsystem cannot boot.
To disable x2APIC mode on Windows 10 or Windows 11, go to the BIOS settings screen and select the setting related to x2APIC mode and set it to disabled.
For additional information to go to the BIOS settings screen, please refer to the manual of the PC.
Disable Intel Virtualization Technology and VT-d
It is recommended to disable Intel Virtualization Technology and VT-d from the BIOS if the CPU supports Intel Virtualization Technology.
If Intel Virtualization Technology or VT-d is enabled, RTX Subsystem may not start and other problems may occur.
To disable Intel Virtualization Technology on Windows 10 or Windows 11, go to the BIOS settings screen and select the setting related to Intel Virtualization Technology and set it to disabled.
Disabling these option will also disable the Windows Memory integrity security feature. Note that the Windows Memory integrity security feature is not compatible with RTX64 Runtime.
Disable Automatic Windows Update
Windows Update for PCs with RTX installed must be managed.
This is because Windows Update may cause incompatibility between RTX and Windows.
Be sure to disable automatic Windows Update and check the compatibility of RTX with Windows before installing RTX according to the following page.
