I’ve been doing some tests with the STM32F407 to see how fast it can go, STMicro has released an almost identical one that runs at 180MHz, is it a marketing thing ? will they release a 200MHz version in a few months? who cares, anyway, I was able to run the STM32F407 at 240MHz without any “obvious” problems, in addition to overclocking, the code listed below lets you set some different frequencies, which could be useful for frequency scaling.

    I’m more curious if you can heavily underclock it to save power…
