How do I stop GPU stutter during magic effects in FINAL FANTASY XVI?

Magic effects stuttered because GPU frequency jumped between 1800-2000MHz. I tried overclocking to 2400MHz, but the system blue-screened. I used the GamePP BIOS Load Line Voltage Adjustment Wizard to set voltage to 1.05V and lock frequency at 2200MHz. 3DMark stress test showed a stable score of 15000. GamePP Hardware Sensor Page confirmed GPU temperature dropped from 75°C to 68°C, ensuring smooth visual effects.
