How to Change CPU Frequency or Speed for ESP32 Modules via Arduino IDE

Code to copy into Arduino IDE:

#include "esp32-hal-cpu.h"

void setup(void)
{

setCpuFrequencyMhz(80); //Set CPU clock to 80MHz fo example
}

void loop()
{
}

Links for buying ESP32-PICO-KIT:

Good quality link I bought this from:

Female header and ROHS compliant version:

Other sites to order from:

TinyPICO ( a low power version of the ESP32):

CAD model for ESP32-PICO-KIT:

I tried to change ESP32 WROOM 32 from 80 MHz to 240 MHz but my timer does not run faster, which indicates that the CPU frequency has not changed. Only when I set it lower, e.g. 40MHz it works.

If i want to change the frecuency of ESP8266 what library should i have to use?

I tried it on ESP32 WROOM 32 and although the speed is set, the timer became slower meaning the Prescaler is still dividing 80 MHz

Its not work, i try to change to 320 mHz and the response its still 240 mHz, any solution ? Thank you !
