I'm sorry if this isn't the right area. Teensy uses the arduino ide.

I've seen some people show off the 144 mhz and 168 mhz option in their ide. I read in the Teensyduino 1.19 release notes that the options were added but not enabled. I would like to know how to enable it or if I somehow downloaded an older version.

P.S I get the 96 mhz option.

Thanks ahead of time!

Using the latest Teensyduino distribution as of this writing, 1.25, you have to uncomment the higher overclocking options in the boards.txt file, located here in my install- /hardware/teensy/avr/boards.txt

The options look like this, just remove the # symbol-

#uncomment these if you want to try faster overclocking
#teensy31.menu.speed.168opt=168 MHz optimized (overclock)
#teensy31.menu.speed.144opt=144 MHz optimized (overclock)
#teensy31.menu.speed.120opt=120 MHz optimized (overclock)`
