I can confirm that the Fall Creators Update (with clean install of latest drivers, 387.92) has unfortunately not helped the issue, nor any of the recommendations by Brecht in the previous post.

I could reproduce some rather random crashes with the official 2.79 release, a GTX 1080 and driver version 385.69 on Windows 10, for example in classroom_gpu.blend. Most of the time it works, but sometimes it crashes almost immediately.

Rendering the "Production Benchmark" (Victor scene) never works here, due to running out of memory. But it didn't work in earlier Blender versions for me either, 8 GB might just not be enough memory to render this scene.

I haven't been able to repro any crash with the latest daily build (97eefc1) so far, but that might be a coincidence since this crash is quite random for me. Can anyone else confirm if there is still a crash in the latest builds?

UPDATE:
Yesterday I installed the newest Nvidia Driver: 385.69
this seemed to fix the crash.
agent 327 renders fine on gpu even with larger tile sizes (though 256x256 lead to blender crashing completely -> other topic)

Was hopeful at reading this, but unfortunately it has made absolutely no difference for me. I even used DDU to reinstall from scratch to be safe, but I'm still having the exact same problem, so I guess you're lucky if you're not having the problem anymore!

@Maeldor (Maeldor), if you don't overclock, then things should be working stable. Root of your issue might be different from @Stefan Eisenreich (Stef1309).

There is one more thing you can try: render file from console (cmd.exe), something like:

path\to\blender.exe --debug-cycles --factory-startup -y -b path\to\bmw27_cpu.blend -f 1

and see if that works and whether log gives any clues.

Thanks for your quick reply!

@Maeldor (Maeldor), did you try rendering default cube on GPU? Did you try installing driver downloaded directly from nvidia.com ?

I am also getting the CUDA error: Illegal address in cuCtxSynchronize(), line 1372 error on the majority scenes I attempt to render via GPU (e.g. BMW Benchmark, Racing Car, etc.). Unfortunately, it's making GPU rendering unusable for me, as I can't tell from one render to another if it's going to crash, and it requires a complete restart of Blender to be able to attempt rendering again.
