When does this Error Code Occur?

nvlddmkm is a software component of Windows that acts as a bridge between the hardware and software counterparts of the computer. It stands for Nvidia Windows Longhorn Display Driver Model Kernel Mode Driver. However, the ‘nvlddmkm.sys’ error code occurs when a task (editing, gaming, or rendering) requires a large portion of graphics memory for a long time.

Why does this Error Code Occur? – the Probable Reasons

The exact causes of this error are different for each use case. But the following are the most common reasons for this error message.

  • If the graphics card has a damaged component, your card heats up and it doesn’t allow higher clock speeds. This behavior results in the BSoD error followed by the ‘nvlddmkm.sys’ error code.
  • The NVIDIA graphics driver has to respond to the Windows operating system in a specified time. But when the driver doesn’t respond within a short deadline, it is the job of TDR (Time Detection and Recovery) to reset the functioning of the driver. That is when the ‘video TDR failure’ along with ‘nvIddmkm.sys’ error occurs. As a result of it, you see the Blue Screen of Death issue.
  • Sometimes, when the system is in the Adaptive power mode, battery saving is the priority of the system rather than the performance. That is when people also face the ‘nvlddmkm.sys NVIDIA corporation video_tdr_error’ issue.
  • An overclocked graphics card might be the reason for this issue.
  • A faulty graphics card can also be the reason for this issue.
  • Sometimes a corrupted or incompatible graphics card driver can also cause problems.

How to Fix this Error Code? – the Solutions

Before trying any complex solutions, we recommend running the SFC scans and DISM tool to check whether the system reports any error or not. Sometimes, the DISM and SFC scans can solve discrepancies in different files.

However, if the built-in troubleshooters don’t fix this issue, try the following solutions.

1. Underclocking the Graphics Card

If you are experiencing a Blue Screen of Death (BSoD) error followed by the ‘nvlddmkm.sys’ error code, we recommend downclocking/underclocking your graphics card. People use different applications to underclock graphics cards, but we’ll do the underclocking/downclocking with MSI Afterburner.

  1. First of all, open MSI Afterburner. But if you have not already installed it on your system, then navigate to the following link to download and install this software:
