Resolve Timeout Detection and Recovery - WINDOWS 7 (32/64 bit)

Create a registry key in Windows to change the TDR settings to a higher amount, so that Windows will allow for a longer delay before TDR process starts.

Open Regedit from Run or DOS.

In Windows 7 navigate to the correct registry key area, to create the new key:

HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Control>GraphicsDrivers.

There will probably one key in there called DxgKrnlVersion there as a DWord.

Right click and select to create a new key REG_DWORD, and name it TdrDelay. The value assigned to it is the number of seconds before TDR kicks in - it > is currently 2 automatically in Windows (even though the reg. key value doesn't exist >until you create it). Assign it with a new value (I tried 4 seconds), which doubles the time before TDR. Then restart PC. You need to restart the PC before the value will work.

Source from Win7 TDR (Driver Timeout Detection & Recovery) I have also verified this and works fine.
