my computer is kinda messed up as is but i came across the HOTKEY OC feature and became interested.
MB: GA P55A UD4P
CPU - i5 760
i downloaded the required hotkey OC program - easy tuner 6 -  and installed it.
I saved 3 different settings:
1)3.4ghz - (Ctrl + Alt + F1)
2)4.0ghz - (Ctrl + Alt + 3)
3)4.2ghz - (Ctrl + Alt + 0)
When i try to apply on of these settings, a message comes up every time:
         "Please reboot computer!
 In Order to affected all modified settings!"
Is there a fix to this problem beside rebooting the computer? 
If i had to reboot the computer every time,
 i mind as well as save the headache and use my CMOS.
