Hello community,

I getting my hands on STM32cubeMX tool for first time to generate project for STM32F405RG. The board has 8MHz oscillator connected to  OSC_IN, OSC_OUT pins. I was trying to configure the board to run at 168MHz, but I was only able to configure max 108MHz.

However I was able to configure 168MHz using the other clock configuration tool:

How could I be able to clock the MCU to 168MHz ?

Pls find the attached files ( STM32cubeMX project file, MS EXCEL clock config tool screenshot).
