![]() This command should also tell you what your CPU clock speed is configured to be limited to. As you use your Raspberry Pi, the requested speed will boost to its upper level, which is 1500000. This will tell you the minimum CPU frequency in hertz ( what it should be when idle ): cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq To get the actual speed, enter: vcgencmd measureclock arm. This will tell you the maximum CPU Frequency in hertz ( what it should be when the system is under load ): cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq ![]() It will likely be lower than the max value if it is idling. This command should show you what your current clock speed is. To set the CPU clock frequency to 2147 MHz, the GPU frequency to 750 MHz, and to increase the CPU/GPU core voltage, add the following lines at the end of your /. The clock speed of the CPU will change depending on CPU load. For example, to set the date to March 3, 2020, you would type: date -s at the command prompt. Oftentimes people do this when overclocking their systems. To change the time, use the date command. Checking the CPU speed of a Raspberry Pi device is easy.
