Hello everyone, at the beginning of this year I bought a microcontroller, it was a version with 400MHz clocking, at the moment CubeMX allows you to change the frequency to 480MHz, can I change it, will everything work properly. Best Regards

I've got 400MHz spec H743's running at 540MHz with no issue including running FMC, LTDC and USB peripherals

The maximal core clock speed specified in the datasheet is guaranteed for the whole temerature range, especially the maximum temperature.
Expect fails (crashes) at higher temerature with overclocked devices.

Thank you for the quick reply, I will take this into account.
