The Video TDR Failure nvlddmkm.sys BSOD error has been an issue for quite a while, and even minor changes, be it updating/upgrading the OS or the driver has been found to trigger the error for many users.

Since TDR is meant to prevent BSOD errors and other crashes, this error particularly has users concerned.

What does video TDR failure mean?

The T in TDR stands for Timeout, D for Detection, and R for Recovery and its role is to identify if the OS is non-responsive and may crash. The nvlddmkm.sys error is most likely related to the driver for your graphics card.

So if you encounter this BSoD, first you’ll have to check your GPU drivers. Here are some other possible causes for TDR failure:

  • Outdated drivers – Running an outdated driver is the most common reason behind the problem.
  • Incompatible drivers: If the driver installed on the device isn’t compatible with the OS, you are likely to encounter errors.
  • Overloading the GPU – Oftentimes, if there’s too much load on the GPU, especially during excessive gaming and video rendering, it may crash and throw the error.
  • Overclocking – Changing the default configuration, increasing the voltage, and making other hardware-related changes to increase performance can often lead to the Video TDR Failure nvlddmkm.sys error.

What causes GPU TDR?

TDR is caused by a fatal error related to your GPU driver. Most often, your graphics drivers are outdated or not compatible, but you can encounter this error in various scenarios and devices. Here are some of them:

3. Change the TDR value

Note icon NOTE
This method involves making changes to the Registry which is a complex process. We recommend you first create a restore point and then follow the instructions as it is to avoid any issues.

A quick workaround to fix the stop code Video TDR Failure nvlddmkm.sys is to change the TDR values. Setting it as 60 worked for users, and we recommend you try the same.

1. Press Windows + R to open Run, type regedit in the text field, and click OK.


2. Click Yes in the UAC prompt.

3. Now, paste the following path in the address bar and hit Enter:Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers


4. Locate the TdrDelay and TdrDdiDelay DWORDs on the right.

5. If you can’t find both, right-click on the blank portion, hover the cursor over New, select DWORD (32-bit) Value, and name it as TdrDelay.

6. Double-click on the newly created DWORD, choose Decimal under Base, enter 60 under Value data, and click on OK.


7. Once done, create another DWORD, name it TdrDdiDelay, and similarly, choose Decimal under Base, change the Value data to 60, and then click OK.

8. Restart the computer for the changes to come into effect.

In you still receive the VIDEO_TDR_FAILURE nvlddmkm.sys BSOD, delete the two DWORDs created earlier, and contact the GPU manufacturer for more help. At this point, it’s likely that the problem lies with the hardware itself.

There you go! We hope that one of these solutions helped fix the annoying VIDEO_TDR_FAILURE nvlddmkm.sys error on Windows. Also, find out how to make Windows faster than before.
