Start by increasing the core clock and memory clock speeds gradually, testing for stability and temperature after each adjustment. Keep an eye on the temperature and make sure it stays within safe limits. It's important to note that overclocking can void the warranty and potentially damage the GPU if not done carefully, so proceed with caution. **

Ultimately, the effectiveness of each practice depends on the individual's specific needs and goals. **
