Twice in last couple days have had entire OS crash with a blue screen while rendering in Corona. Appears to me to be my processor crashing (text on the blue screen disappears to quickly to read), but that's odd as before I settled on this overclocking - it's an Intel i7-5930K overclocked from 3.7Ghz to 4.2Ghz with water cooling - I ran the system through really brutal CPU and video stability tests for extended periods, like many hours. And haven't had it crash like this since initial overclocking experimentation back in December, and have played a bunch of intensive games and have been working in Photoshop and MAX.
Also strange that I was playing with Corona for several days and then twice in last 24 hours it's crashed like this.
So mentioning it in case there's an issue in Corona or at least you know Corona is capable of pushing CPUs even harder than CPU stability tests, so overclockers beware. If you want info about my machine let me know, but like I said looks to me like processor couldn't handle what Corona was asking of it at this overclocking. So going to step it down for Corona, I can change it on the fly. I'll let you know if that doesn't make it go away.
