Is it possible to drive the controller with 480 MHz and therefor the flash with 240 MHz?
How many waitstates have to be set at 240 MHz?

Look for FLASH recommended number of wait states in the reference manual.

In Table 13 in reference manual (DS12110 Rev 7) the maximum frequency is 225 MHz (see attachment). But in Comment (1) there is a reference to the maximum product Faclk frequency (240 MHz).
If I config the Faclk freqency to 240 MHz in the STM32CubeMx there is no error and the controller is running well.

Can you double-check you're looking at the right document.
For stm32H743, the Reference Manual is RM0433 for "STM32H742, STM32H743/753 and STM32H750 Value line
advanced Arm®-based 32-bit MCUs"
And that states in Table 17 that you need to be in VOS0 to go to 240 MHz.

Thank you. I've got the wrong version :face_with_tears_of_joy:
