The frequency will depend on how you initialize the display. There is information about how different settings affect the frequency on page 22 of the controller datasheet: https://www.crystalfontz.com/controllers/Solomon Systech/SSD1306

In our demo code we demonstrate this:

//Set the clock speed, nominal ~105FPS
//Low nibble is divide ratio
//High level is oscillator frequency
sendcommand(0x80);//177Hz measured
