GPU rendering puts my workstation to sleep

I’d love to use RT more these days, but whenever I render anything more complex than a single object, it completely freezes my machine. Not only does the frame buffer only update every ten minutes or so, but Max gets completely unresponsive so that I can’t stop the render. I’m on Win 7, using one Titan X card.
Anyone had that problem and is there a workaround?

Please check here, chapter Balancing the GPU Load - Chaos Docs to see if this will help. You can go as low as 16/1 with the Bundle Size / Rays Per Pixel.
If you have multiple GPUs, you can leave one exclusively for the monitor and exclude it from the rendering (this helps the most, of course).

Thanks a lot. I’ll give this a try.
