What Causes NVLDMKM.SYS Latency Errors?

nvlddmkmsys latency

This is an annoying error that occurs in Windows while using the video card, but it can also occur when a hardware component of your computer stops working. It might be a graphic card issue, memory issues or a storage device.

It can be solved by updating the BIOS of your computer. It will help make sure that the graphics card and motherboard are properly mingling with each other.

TdrDdiDelay

There is a small side effect that can happen with the Windows WDDM display driver. Specifically, it can hang the graphics card if too much data is being rendered at once.

The WDDM display driver uses a system feature called Timeout Detection and Recovery (TDR). It watches for such situations and automatically resets the GPU if it occurs.

If you’re looking to curb this issue, you can edit two registry keys: TdrDelay and TdrDdiDelay.

To add them, open the Registry Editor and select New > DWORD (32-bit) Value. Give the values a name like TdrDelay or TdrDdiDelay, and then set their Base to Decimal.

This will delay the time that Windows waits before reporting a video TDR failure. This should give you enough time for the GPU to be able to process the data before the error occurs. However, this solution is not intended to resolve all video TDR issues. It’s only designed to help avoid crashes that are based on rendering.

TdrDdiResetFromTimeout

Timeout Detection and Recovery (TDR) is a feature built into Windows Display Driver Model (WDDM) that monitors if a computer appears to be “frozen” or “hanging”. The operating system attempts to reset the graphics driver if it has not responded within a specific period of time.

TDR is most commonly used during periods of intensive graphical operations, such as video editing or game play. It also helps prevent the need for a full system reboot in these situations.

Troubleshooting TDR errors requires a thorough, organized approach that involves performing the quickest/easiest steps first before moving onto more complex ones. A systematic approach ensures that the problem is correctly diagnosed, which prevents recurring issues.

If the issue persists after following these tips, you may wish to consider modifying the TdrDelay registry key in the Windows Registry. This change is not recommended as it can cause data loss or operating system corruption. You should also backup any important files before attempting to modify the registry.

TdrDdiTimeout

TdrDdiTimeout is a feature of Windows that monitors response time from the graphics card and automatically resets it to recover a functional desktop environment. Using this feature, it helps reduce the risk of Blue Screen of Death (BSOD) crashes when the GPU stops responding.

The feature uses the new WDDM driver model introduced in Windows Vista, but is not available on earlier versions of the OS.

It is a vital part of Windows’ stability mechanisms and is used when a GPU process is taking too long to complete. Hardware vendors should ensure that graphics operations on their hardware take no more than 2 seconds in end-user scenarios such as productivity applications and game play.

If the timeout threshold is exceeded, a TDR detection event is logged in the Windows Event Viewer and if the end user opted in to provide feedback, this debug report is sent to Microsoft through the Online Crash Analysis (OCA) mechanism.

TdrDdiRestartFromTimeout

The Windows(r) operating system has a feature called Timeout Detection and Recovery (TDR) which attempts to reset your graphics driver if it hasn’t responded within a specified amount of time. This allows your computer to resume normal functionality without requiring a reboot.

However, this isn’t always a viable solution for every problem. For instance, if you’re running an application that uses the GPU to fully process data, the TDR technology might not be able to handle it.

Luckily for us, Windows provides the option to tweak the timing of the TDR function which allows you to configure the graphics driver to respond in a much shorter amount of time. Specifically, there are two main options: the first is to set the WDDM TDR to the maximum level of performance which will allow you to set the clock speeds to their maximum possible levels. The other is to adjust the TDR function itself by modifying the registry.
