Install a GPU monitoring tool such as MSI Afterburner, HWiNFO, or the vendor’s tuning software
Open the tuning software and reset any previous overclock settings
Run a stress test or a demanding game to note baseline temperature, power, clock speed, and stability
Open the voltage-frequency curve editor if available
Reduce the voltage at your target boost clock in small steps
Keep the same or slightly lower clock speed while lowering voltage
Apply the changes
Test stability with a benchmark, stress test, or game
If stable, lower voltage a little more and test again
If unstable, increase voltage slightly or reduce the target clock
Repeat until you find the lowest stable voltage
Save the stable profile
Monitor temperatures, power draw, and performance after daily use
Restore defaults if you see crashes, artifacts, driver resets, or performance issues
