Are you sure this is the same as the TDR? Project 11411 is not very large, so it would be surprising if one of the GPU kernels was exceeding the windows timeout on a GTX 970.
clEnqueueNDRangeKernel (-5) error + GPU reset logged in Event log is typically the TDR issue.

But the TDR is not necessarily triggered by software misbehaviour. The purpose of TDR is to detected unresponsive GPU to avoid a frozen screen, like we used to have on previous Windows. There are two sources of freezes :

- when software sends too much work to the GPU. First step of this is sluggish UI, then as the work is getting even bigger, it leads to longer freezes. This is the form of TDR triggered by large WUs that you tried to workaround in core21.
- when an unrecoverable error occurs in GPU or VRAM. This one is usually triggered by too much overclocking, or faulty/dying hardware. This one is similar to the freezes that could happen on CPUs in case of unstable overcklocking ...

@Duce H_K_: Maybe you can use FurMark to test your GPU overclock to be stable?

@Duce H_K_:
GPU-Z shows "Boost 1443 MHz" (see your screenshot). If you press "Sensors" you will see real GPU frequency. On your second screenshot MSI AB shows 1493 MHz. This is real GPU frequency. 1493 MHz is high OC.
My GTX 970@1430 MHz/1.1870V, vMEM@6010 MHz works well for now with core_21 v 0.0.14.

When running FAH, overclocking VRAM is usually a bad idea. More power, more heat, almost no change to performance.

Use default memory speed and push the shaders a bit more if that leaves more margin.

Just a quick note. I've had zero failures since the core 21 WUs were removed for this card. The core 21s are working just fine on my ubuntu system with the 750ti.zero failures there as well.

@Kebast: There is a new version Core_21 to be released which will fix many of the bad states.

I'm not sure if I should tack on to the end of this thread or not, but I believe I had a core 21 failure on my GTX 970 this evening. It's kind of hard for me to tell for sure if it's the 970 or the 750 TI that failed since they are not identified properly in advanced control. But, I believe it was the 970.

Here's the beginning of the log:

This is the FahCore_21 warning on first start:
05:28:53:WARNING:WU02:FS02:FahCore returned: FAILED_3 (255 = 0xff)
After that FahCore_21 started again without a problem.
