Hello, I have an issue with my freezing PC during running phoenix miner. I have 5700 XT Red Devil, Bios moded (running on win 10, desktop). I have this OC:
Core Voltage = 900
Power limit = 80%
Core Clock = 1350
Memory clock = 1790
Fan speed = 70% (fix) (avg temp during mining is 48cels)

miner with this set up starts working, 54,8 MH/s, 120w. Accept shares, no rejections, and after 30-60 min without any reason all PC freeze. No other programs expect Miner and afterburner are running during mining. Do you have any idea where could be problem?
