WebJan 22, 2015 · In case of any STM32F4xx Discovery board, select PLL_M = 8. This will divide input clock with 8 to get 1MHz on the input for PLL. If you don’t use external clock, then this value MUST be set to 16, because internal RC will be used for PLL. Now you can expect top speed for your device.
