Check the settings in QCPUFreq that you have overclocking enabled. It is in the main menu of QCPUFreq.

And the above comment's purpose was that you would run the commands in x-terminal as root user and put the output in this thread so people who try to help would get information they need.

(QCPUFreq would be much more useful if it would support those voltage-settings which come with kernel-config. Also, if someone has played and has some kind of wrong settings, like I had when all other things were working but DSP-acceleration wasn't, QCPUFreq won't notice it and although the device is rebooted QCPUFreq takes the old (non-working) settings in use. So, with the other pre-set voltage-frequency-settings there could be "set normal" in QCPUFreq which will reset all voltage and frequency-settings to normal non-fiddled values.)
