How to stop black screen reboots in God of War Ragnarök combat?

I experienced sudden freezes and black screen reboots during high-difficulty combat, which caused me extreme anxiety. I attempted to manually lock all-core frequencies in BIOS; this stopped the fluctuations, but my idle power soared to 130W per HWInfo and introduced weird micro-stutters. I eventually utilized the GamePP BIOS Load-Line Calibration Guide to set LLC to Medium and VDD to 1.32V. Verification via CPU-Z confirmed peak temperatures were suppressed to 82-86℃, and a Stress Test showed a stable range of 75-82℃. No more crashes at 82℃
