i got some problem and thinking about is it hardware problem or something else. The problem i had is that i bought new PC to videoeditting, and tried to make some movies but when i throw some 4K videofiles on timeline and try to play it back i got PC crash, all freeze and had to reboot whole system. From the beginning i enable boost mode to 4.2GHz. First i though its Premiere Pro problem but it wasn't. I just tried to run cinebench and in test i got the same result - PC crash. I understand that PC got stuck when have to do multiple tasks. I disable boost mode and on 3.7GHz it works very well. And now is my question, is it normal that this PC crash on boost mode? or i have bad one sample?
My PC is Ryzen 2700x+MSI x470 Gaming Pro Carbon AC+MSI GTX 1070Ti+G.Skill 32gb(2x16) 2933MHz 16CL+Samsung 960 evo 250GB+Corsair 650RMi
got good airflow (2x 140 in front and 1x120 back + 1x120 top
