user3159: 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!

user14245: 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)`
