How to change TDR values and edit "Registry keys".

Hello Ahmed.Ahmed.Mohammed

Welcome to Microsoft Community.

According to your current needs, it seems that there are some questions about the process of editing the "TDR values" of the GPU. I will try to answer your questions in terms of text or pictures. Because the community can only provide this type of support, assuming you need support personnel to help you through remote assistance, we also provide phone support.

Generally Speaking, TDR stands for Timeout Detection and Recovery and it is a feature of Windows that detects when the GPU is taking too long to complete a task and tries to recover from the situation.

To edit the TDR values, you need to modify some registry keys under

The registry keys are:

• TdrLevel: Specifies the initial level of recovery. The default value is 3, which means recover on timeout.
  
• TdrDelay: Specifies the number of seconds that the GPU can delay the preempt request from the GPU scheduler. This is effectively the timeout threshold. The default value is 2 seconds.
  
• TdrDdiDelay: Specifies the number of seconds that the OS allows threads to leave the driver. After a specified time, the OS bug-checks the computer with the code VIDEO_TDR_FAILURE (0x116). The default value is 5 seconds.
  
• TdrDebugMode: Specifies the debugging-related behavior of the TDR process. The default value is 2, which means recover without breaking into the debugger.
  

To modify these registry keys, you need to follow these steps:

1. Open the Run dialog box by pressing Windows + R keys on your keyboard.
   
2. Type regedit and click OK to open the Registry Editor.
   
3. Navigate to the following path:
   
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers
   
4. By expanding the folders on the left pane.
   
5. Right-click on an empty space on the right pane and select New > DWORD (32-bit) Value.
   
6. Name the new value as one of the registry keys mentioned above (for example, TdrDelay).
   
7. Double-click on the new value and enter a desired value in the Value data field (for example, 10 for 10 seconds).
   
8. Click OK to save the changes.
   
9. Repeat steps 4 to 7 for any other registry keys you want to modify.
   
10. Close the Registry Editor and restart your computer for the changes to take effect.
    

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

I hope this helps you with your issue. If you have any further questions, please let me know.
