Set power limit to the maximum safe value available
Increase core clock in small steps
Test stability after each increase
Increase memory clock in small steps
Test stability after each increase
Monitor GPU temperature, fan speed, and power draw
Adjust fan curve for better cooling
Lower clock speeds if crashes, artifacts, or overheating occur
Run benchmark or game tests for extended periods
Save stable settings as a profile
Restore default settings if instability persists
