I am assuming you are using the image from the following page:

How are you powering up? If BBB is powered from USB it is throttled to 
consume less power. Use a 5V DC supply. Also make sure that you are 
completely booting from the sdcard. This way you can be sure that the 
u-boot  you are using supports 1GHz operation. Refer the User Guide for 
details.
