Change the speed of the processor on RouterBOARD 1100AHx2

Is it possible to change the speed of the processor on RouterBOARD 1100AHx2 from 1066 MHz to 1333 MHz without the risk of failure of board?
Can I do it on the fly?

Yes, you can try. Set this in the “/system routerboard” menu. There is no risk of damage, but if device becomes unstable, simply set it back to default setting.

Thanks for your reply

the rate changed, but in resources is still 1066MHz.
Need to reboot the board?
I fear that it will not rise after a reboot?
It is very inconvenient to go to another city, if it falls, I work remotely)

yes, to apply change of speed, reboot is required. there is no reason to think that device will not boot

ok, thanks
