    Teensy 3.1 overclock to 168MHz

    EDIT: This is already in Teensyduino 1.19 and up.
    Don't use my repository @ github anymore.


    i successfully overclocked my teensy 3.1 to 120 MHz.
    Busclock is 40MHz, Flash 30MHz.

    If anyone is interested, I can upload the changes at github.
    Additionally,i changed some of the GCC - switches for speed-optimization, not size.

    120 is easy selectable:Tools -> CPU Speed -> 120 MHz(Overclock TURBO)


    Edit: Runs for 18 Hours now, without any problem.

    Edit: Download is here, now with 120MHZ || 144MHz || 168MHz
