I have been looking through this website and have been unable to find detailed instructions on how to overclock the cubieboard2. Can someone please help me? My script.bin file has been modified according to the first comment on this post,,626.msg3307.html#msg3307, but I have no idea how to perform the "This lets me do cpufreq-set -g ondemand -u 1.4G  stable" action. See here -

From what I have seen in other posts, you need to run the command as is: 'cpufreq-set -g ondemand -u 1.4G'

That should set the CPU frequency. But be careful how far you go. I would stick to what people say works.


Thank you for the reply, I have it working now! Makes me feel stupid, when all that there was to do was simply drop the "stable" from the end of the command.


Just one more thing though, I did a reboot to see if the settings would stick, but its looking like I will have to do that command on startup every single time in order to always have the overclock. Is there a way to fix this so that it boots overclocked? Or at the least is there a way to set a terminal command to run at startup?


Add startup commands to the file /etc/rc.local.
