[All good now, I was able to find what I screwed up]
hello friends 
I landed a good one… When rendering away with Cycles + ticking Denoise (using my Raedon GPU) I get a blue screen of toast.
When I don’t have Denoise ticked it renders flawlessly
The GPU doesn’t overheat… the stats are good…
Does someone have a good idea?
Thank you
maybe run a memtest to rule out hardware issues.
does cpu work? whats your system? what blender?
GPU: Outstanding
Drivers: Bourbon on the Rocks
User (me): Instabil
Problem solved…
I have found a massive memory jam going on.
I overdid it.
I am rendering at 35mm and set the same to the tile dimensions under performance ^^
that would do it. 256x256 tiles are the recommended for gpu.
