420Mhz!!! Warning, your mileage may vary. Overclocking could shorten the life of your Pico, although mine seems fine :-)
In this video I show how to set the Pico CPU clock from under-clocking to save power all the way to maximum overclock which for me topped out at 420Mhz!!! Beware however there is a catch... with the maximum overclock your flash memory will stop talking to your pico CPU. This is recoverable so don't worry just load another program with a different clock speed.
