NUCLEO-H753ZI Clock speed 480MHz

[TVan .8]

Does anyone how to clock the NUCLEO-H753ZI to 480MHz?

With this clock configuration it runs perfectly on 400Mhz, if I put the DIVN1 from the PLL1 a little above 200, in order to get a clock speed over 400MHz the board is stuck. STM32CubeMX and STM32CubeIDE give no error, the code compiles fine, but when I upload the .elf file the board is bricked.

It should be able to run on 480MHz.

Hello @TVan .8,

I advise you this article: How to reach 480MHz for STM32H7xx MCUs?

Please follow the described steps to run on 480MHz.

Hope this helped you:
