How do I stop sudden black screens and restarts in Black Desert (Remastered) on i9 13900K?

The screen went black during a final battle, which was incredibly annoying. I tried replacing the 24-pin power cable with a thicker one, but the loose connection caused even more issues. I then opened GamePP Resource Scheduler, set the game process priority to Real-time, and monitored the memory controller load. Cinebench R23 multi-core loop test showed voltage fluctuation converged from 0.05V to 0.01V. Power fan speed remained stable at 800-1000 RPM per AIDA64. This specific adjustment was the key to fix the unpredictable crashes.
