Now, it's time for gradual increments. Increase the core and memory clock settings in small steps, typically 10-25 MHz. Apply the changes and stress test after each adjustment. Keep an eye on temperatures and stability.

Step 7: Find the Sweet Spot

Continue this process of incremental increases and stress testing until you reach the point where your GPU shows signs of instability. This could manifest as screen artifacts, crashes, or elevated temperatures. Once you reach this point, you've found your GPU's sweet spot.

Step 8: Fine-Tuning

At the sweet spot, it's time to fine-tune your overclock. Try small adjustments in both directions to ensure optimal performance without instability.

Step 9: Maximize Power Limit and Voltage (Optional)

You can sometimes maximize performance further by increasing the power limit and voltage. However, this requires in-depth knowledge and should be done with caution. Not all GPUs support voltage adjustments, so consult your GPU manufacturer's guidelines.

Step 10: Save and Apply Settings

Once you're satisfied with your overclock settings, save them as a profile in your overclocking software. This allows you to revert to your stable settings if needed easily.

Step 11: Monitor Temperatures

After you've applied your overclock, monitor your GPU's temperatures during regular usage and gaming. Make sure it doesn't exceed safe limits.
