Hi, when I use the cubemx to config the stm32h743iit6 project, the clock system shows some error as below. But I try it on another PC, and the same config can work well.
I don't know why?

Hello @Junde ,
For the STM32H743 , we have 3 revisions : V , Y and X. (errata sheet)
Use silicon revision V devices to reach a maximum frequency of 480 MHz.
Please make sure which revision you have and you can refer to :

Thanks for your reply.
As per your description, there are different revisions on RCC config page(but just rev.Y and rev.V, NO rev.X).
And I want to know how to make sure which revision the chip I have is.
Just see the silk print on the chip surface?

Yes, you can just look at your MCU.
Or try to connect your board to the STM32CubeProgrammer.
