I see that the configuration for the pyboard lite and the STM32F411DISC set the STM411(RE) to run at 84 Mhz even though it can run with up to 100 Mhz. Is there a particular reason for this?
Update: Oops, sorry, it's 96 Mhz for the pyboard lite. But 100 Mhz should still be possible, shouldn't it?

I believe you can't derive the 48MHz USB clock when you set the PLL to 100 MHz

Re: Clock configuration and SYSCLK for STM411RE
Yes, I figured this out myself after I had written the post. The closest you can get is 50 Mhz for the peripheral clock - or you overclock the cpu at 108 Mhz
Still leaves the question why the STM32F411DISC is configured at 86 Mhz instead of 96 Mhz?
