GPU System Stability Test Threshold Setting (Timeout Detection and Recovery delay a.k.a. TdrDelay)

[Jeff Fritz]

When I ran the GPU stability test for the first time, AIDA64 warned me that I should increase (or decrease?) some threshold or time setting for graphics driver responsiveness. I said ok, make the change.

Whatever this feature was called - I can't recall, how do I reverse the change? I want to troubleshoot some video problems that have been occurring since I made that change.

It's called the Windows video driver Timeout Detection and Recovery delay (TdrDelay).  You can adjust it using Registry Editor (REGEDIT.EXE).  You can find it at the following path:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers

Look for TdrDelay there.  It should be set to 8 right now (previously set by AIDA64).

That's it. It's set to 8 right now. Per some googling, apparently 2 (seconds) is the default. Thanks for the help.
