Has this ever happened before you installed the Hybrid kit?

Remove PXOC and NVIDIA Drivers and Delete the Profile Folder.
Run DDU in Safe Mode and then Install the NVIDIA Driver you want to use restart your PC and Install PXOC and see how they run.

Precision isn't going to recognize your ftw3 card as a ftw3 hybrid card as your current card doesn't have the hybrid vbios loaded to it. I bet your driver crashed and recovered when the screen froze.
 
When the graphics driver crashes & recovers during a 3d load clocks will get locked to a lower value until you close the 3d app & let the card return to idle clocks (139/405). Sometimes you'll need to reboot the machine to restore normal clocks. 
 
A unstable overclock can cause the screen to freeze up & the driver to crash & recover. +60 seems to be too high of an overclock for your card. Start with +20 and work your way up in +20 increments.

I agree with this guy. My FTW3 will boost to 2025 with just a +25 on the core clock while the temps are below 40c which that lasts about 10 seconds lol. 

I agree with Sajin.  Your card will NEVER be recognized as a Hybrid because it's not a factory Hybrid.  Period.  As for your clocks, when the driver crashes, all hell breaks loose.  Just because you installed a Hybrid kit doesn't mean you will automagically get a better overclock.  It still comes down to the silicon lottery.  FTW3 is a pretty high clocked card to begin with and is almost at it's max out of the box.  I myself have a 1080Ti Hybrid that is a serious lottery winner as it can run at 2133 stable all day everyday while folding, but when the driver crashes, it gets locked at 1974 and I need to reboot the entire system to get it back to overlcocked values again.  I now run it at only 2075 and since then the driver hasn't crashed in over a month, so it is now truly stable.
 
 

Ok so every time I make a Change in the Tool for example only setting the Temp Target to 89° Celsius, the program freezes, black screen, some green and black dots (lol) and then I'm back at my desktop but the highest possible Clocks are 1569Mhz... I also deleted and installed the Nvidia Driver in a complete way (delete folders, registry etc.)... I also switched the PCIe Lane on my MB, but nothing seems to solve the problem -.-

-Windwos 10 64Bit
 
-Nvidia Driver 387.92
 
-PrecisionX Version 6.1.16
 
-Nope, no yellow circles. everything is fine
 
-I'm running FurMark GPU Stress Test Version 1.19.0.0
 
-Yes I resetted every change I made in the Bios to default
 
-Temperatures:
 
MB 29°
CPU 40°
GPU 24°
Room 21°
 
I will check the Cables! thx

Did you check this thread ? Basic troubleshooting steps. Windows clean boot, clean driver install, debug mode, etc.
 
What other GPUs have been in this PC ?
 
Other thoughts:
- Download the Newest Nvidia driver -- direct from Nvidia
 
- Download Precision XOX 6.1.14
 
 
 Uninstall Precision XOC
 
     1) Make sure when you remove Precision XOC, you then reboot
 
     2) then you Manually remove the Precision Folder off your drive - look in Program Files (x86), then reboot
 
2B) After removing Precision
 
     Run DDU in default (safe mod with reboot) to remove all traces of old GPU driver
 
     Go offline, stop all background software - Including Security Software
 
     NOW --use the Custom install Nvidia driver with Clean install --ONLY install GPU driver & PhysX   ---> DO NOT install anything else (3D, Sound ....)
 

     3) Now Reinstall Precision, with nothing else running - pull the internet connection - kill security and any other item that's running - Reboot again
 
Note: on newer GPU cards, After you install XOC, shutdown PC, remove the power cord from wall, Remove All Powered accessories (monitor, USB hub ...) press and hold power button on PC 30 seconds - discharge all capacitors, plug everything back in & Restart your PC
Download the Newest Nvidia driver -- direct from Nvidia
 
 
 

Completely uninstall precision x, reboot pc, retest furmark without precision x installed.

Do you experience the issue on both vbioses?

Does the issue only occur in furmark, or does it occur in all applications as well? If all applications...
 
Reinstall the stock cooler to see if it helps make the issue go away. If the issue presists after installing the stock cooler test the card in another pc (family, freind, or local pc shop), or just rma the card.

I had this issue with one of my RMAd cards where it refused to run more than 780 mv and anything changed to the card like fans or clocks will freeze

Hey guys,
 
I am having the exact same issues. Just installed the hybrid kit yesterday. Uninstalled and reinstalled all drivers. Core clock is stuck at the exact speed mentioned by the poster and any attempt to OC will cause a freeze or crash. I can OC memory, but not core clock. Stock it is fine and works with any of the games I'm playing, but maxes out at 1569Mhz. Any advice? RMA?
 
Thanks

Did you reinstall the stock cooler and the GPU operates correctly?

Not yet. I just discovered this issue after installing the kit last night. That would be the next logical step to determine whether anything was damaged during the installation. I'll do that and see if it still works as well as it did before.

It could be coincidence...but nearly identical issues when installing the same mod on the same product makes one wonder if there isn't a fitment problem where something is making electrical contact where it should not.

Could the voltage be the problem? Here is a screenshot taken from GPU-Z while running the Heaven benchmark and it shows the 1569 MHz limit mentioned above.

 

Same thing is happening with me.
 
I reinstalled the shroud three times, as well as the back plate. Temps are great, games run great, but as soon as I load up PXOC or Afterburner, system locks up.
 
I installed the original heatsink and still suffering the same symptoms. 
 
I guess its just time to RMA :(
