Im trying to increase the timeout on the GPU from its default setting of 2 seconds to something a little longer. I found the following link but it appears its slightly different in windows 7 as i cant see anything mentioned in the webpage.
Has anyone done this before? If so could you fill in the gaps please.
Thanks
@RoBik so as follows if i want 6 days (bit excessive i know but just for example)? Thanks again for your help, +1.
EDIT
This is the error im currently getting.
An error has occured and the operation has been terminated. CUDA.NET exception: ErrorLaunchTimeOut.

Disabling TDR removes a valuable layer of protection, so it is generally recommended that you keep it enabled. However, setting the TDR delay too low can cause the debugger to fail for one of two reasons: Debugging on some GPUs will fails with a TDR delay of less than 10 seconds.
TdrLevel. Specifies the initial level of recovery. registry Copy. KeyPath : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers KeyValue : TdrLevel ValueType : REG_DWORD ValueData : TdrLevelXxx (see the following table)
The link in your post is correct, you just need to create the corresponding key with the desired value. You will find the TDR Registry Keys description here. The setting you are looking for is
TdrDelay
Specifies the number of seconds that the GPU can delay the preempt request from the GPU scheduler. This is effectively the timeout threshold. The default value is 2 seconds.
KeyPath : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers
KeyValue : TdrDelay
ValueType : REG_DWORD
ValueData : Number of seconds to delay. 2 seconds is the default value.
What you need to do is to create a new key named TdrDelay of type REG_DWORD under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers and set its value to what ever you desire (value in seconds). After that you need to restart your computer for the setting to take effect.
