The problem is that the chip and the things inside it isn't made for speeds that fast, so I think you would see that the chip will go into the Hard Fault routine most of the time!

About two months ago i plugged 25Mhz crystal on board for Ethernet STM32F107 family when i was changing developmnet platform from STM32F103 at 8MHz clock. PLL was set to 72Mhz when 8MHz crystal was mounted. I did'nt change PLL's configuration for STM32F107, and guess what? It was working ! at 225 MHz with FreeRTOS onboard. Led was blinking faster, PWM was goin faster, UART to ! 128Mhz is just the beginnigng .

I haven't had any problems when running at 128MHz, but I don't know about the ADC, but that would definitely also run faster, but I don't know if any problems would occour then! You have to try it out - also the STM32 won't be damaged or heat up when overclocking. Best Regards Thomas Jespersen Dear Mox.

Does it work sometimes, or will this work reliably? Will the cortex heat up (overheat)? Can the peripherals, namely the ADC work faster (maybe losing a bit or two in reliable resolution)? regards, Mox How is reliability? Does it work sometimes, or will this work reliably?

But I think if you chose to go with 128MHz, you just have to change the USB PLL to a higher value. Thomas About the USB clock I’m not sure, as I haven’t done any projects with USB yet!
