for settings >= 0.5 you don't need rootsh or sudo gainroot anymore.
sudo usr/sbin/kernel-config is sufficient.
@Almedi, Tigerite: your problem with the limits should already be fixed in settings 0.8 that I uploaded this morning.
and then you beat me to the sudo trick as well!

Try to raise the voltage... if you are running the latest kernel-power-settings (i.e. 0.7) then it would look something like this.
1. First you need to make your own settings file:
kernel-config save my-settings
It will tell you the place where it got saved.
2. Then open it with leafpad (might need to install leafpad):
leafpad /home/user/.kernel/my-settings
3. Edit your settings to your likening:
"250:20,180" try edit it to something higher.. like "250:24,180"
The kernel will go back to the default if it should reboot so it is no problems. To set it up permanent you need to "kernel-config setdefault my-settings". This i would wait with at least a week with stable running.
kernel-config load ideal
kernel-config limits 500 850 (or whatever freq. im trying)
thanks

/usr/sbin/kernel-config without sudo does also work .

If you try "kernel-config lock 250 22 180" and it is stable.. then update you my-settings file on that mhz. Try stress it with some youtube videos and things.

So you would run:
kernel-config load my-settings
kernel-config limits 500 850

I think the syntax for the lock command is
kernel-config lock 250 22 180
(without the : and , characters)? Not sure it'll work with those in place..

Im running ideal jsut so but I want to set the lowest limit to 250 and to increase the rate at which the kernel changes up and down between the frequencies
I have set the lower limit to 250, but it seems to ignore this. So do I ahve to unblock this -and if so how?
And is that the sample rate that I change to increase the rate of change between settings

Hi! @Titan
(big noob, here...)
Is it a good or bad thing to us powersave_bias parameter to modifies the behavior of the ondemand governor. So u save more battery power m.m When u oc? if it reduse chances to a good oc
i found this:
The powersave_bias parameter modifies the behavior of the ondemand governor to save more power by reducing the target frequency by a specified percentage. By default, (powersave_bias = 0), the ondemand governor selects the minimum processor frequency that can still complete a workload with minimal idle time. Doing so should result in the highest performance to power efficiency ratio. In some cases, you might prefer a greater emphasis on power efficiency than performance. In this case, set the powersave_bias parameter to a value between 1 and 1000 to reduce the target frequency by one-thousandth of that value. For example, set powersave_bias to 100 for a one-tenth reduction in target frequency. In this case, if the governor chooses a target frequency of 2 GHz (with powersave_bias = 100), the governor instead will request 1.8GHz – a one-tenth reduction. If 1.8 GHz is an exact match with an available hardware frequency (listed in the scaling_available_freq parameter), the processor is set to this frequency. If 1.8 GHz is not available, the processor fluctuates between the closest available upper and lower frequencies for an average frequency of 1.8 GHz.
