CPU stays lowest frequency

[Keroro]

I can not get my notebook to run at higher CPU speeds then 800MHz.
The CPU is a Intel Core 2 Duo T8100 (2.1GHz)
Output of cpufreq-info is

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 800 MHz - 2.10 GHz
available frequency steps: 2.10 GHz, 2.10 GHz, 1.60 GHz, 1.20 GHz, 800 MHz
available cpufreq governors: powersave, conservative, userspace, ondemand, performance
current policy: frequency should be within 800 MHz and 800 MHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 800 MHz - 2.10 GHz
available frequency steps: 2.10 GHz, 2.10 GHz, 1.60 GHz, 1.20 GHz, 800 MHz
available cpufreq governors: powersave, conservative, userspace, ondemand, performance
current policy: frequency should be within 800 MHz and 800 MHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).

Especially the line "frequency should be within 800 MHz and 800 MHz." seems to show the root of the problem.
Does anybody got an idea how to change it?

Re: CPU stays lowest frequency

What policy do you have kpowersave set to? Here I have set policy to "dynamic", and I get this output from cpufreq-info (relevant part):

analyzing CPU 0:
 driver: acpi-cpufreq
 CPUs which need to switch frequency at the same time: 0
 hardware limits: 1.60 GHz - 2.93 GHz
 available frequency steps: 2.93 GHz, 2.13 GHz, 1.60 GHz
 available cpufreq governors: powersave, performance, ondemand, conservative, userspace
 current policy: frequency should be within 1.60 GHz and 2.93 GHz.
         The governor "ondemand" may decide which speed to use
         within this range.

cpufreq obviously does not know that I have set up overclocking in BIOS -- these are default speeds for my CPU.

It is set to performance.
Sometimes when I switch the notebook on it runs at 2.1GHz and then goes through all speed steps within 5 minutes or so and ends at 800MHz where it stays. But that happens just randomly.

Re: CPU stays lowest frequency

Have you loaded it up with a CPU-intensive task, like coding an audio file or something like that?

Re: CPU stays lowest frequency

Is it really necessary or is there any advantage in running KPowersave?

It comes in handy if you want to suspend to RAM, for example.

Yes, i did some heavy filters on a big photo in Gimp.
On my desktop it all runs fine. The laptop makes problems though.
