Check the power regulator voltage scale setting in the RCC settings. If power regulator voltage scale 3 is selected, you cannot exceed 200MHz

Hi,

which particular STM32H7 part is that (e.g. STM32H723ZG)?

Thanks!

Hello @Community member​,

When the configured values are highlighted, it means that they are out-of-range and there might be potential issues.

A solver feature is proposed to automatically resolve such configuration issues. You can click on "Resolve clock issues" so that STM32CubeMX proposes you the adequate values.
