Yes, there are safe methods to overclock your CPU and GPU. You should start by researching the maximum overclocking potential of your specific components, then use free software such as MSI Afterburner or EVGA Precision X to control the clock speeds and fan speeds. Make sure to increase frequency and voltage gradually, and monitor your system’s temperatures carefully. When temperatures reach unsafe levels (above 80°C), you should immediately stop overclocking and lower the clocks.
