ARC A750 short run time
So I recently gotten the intel arc gpu (yes, i'm a beta tester lol) and was using the nanominer to test it's hash rates. I found that not overclocking the a750 goes to about 200w, hits 50.7 mh/s and is stable enough to last around a day without interference. I then tired to reduce the the power limit to 140w, increase Vm to +15 and  increase the memory  clock to +4 in the arc performance slider. It didn't even last for two hours before the system crashed. The gpu temps were around 67c and the vram was at 80c so temps weren't a issue. Is the tunning mechanism in nanominer causing the crash or arc driver instability? Is tuning the Vm an issue or tuning the memory clock?
