undervolting AMD Turion using cpupowerd
Hi Everybody,
I am trying to reduce the temperature of my laptop using undervolting.
I have an AMD Turion 64 MT-28 processor running Hardy 8.04 amd64 version (fully updated).
I found this cool program in a german ubuntu/linux forum called 'cpupowerd'
http://sourceforge.net/projects/cpupowerd
It first reads your current fid/vid (frequency/voltage id) programming and allows you to reduce the cpu voltage at a certain frequency.
Unfortunately, I don't understand german and google translation didn't help me understand how to set and run this all the time either.
For those of you who want to try it out: please note that this program can easily damage your cpu/system if you mix up the settings.
However, I am having issues with turning off powernowd which controls the frequency variation in hardy by default. I have tried /etc/init.d/powernowd stop which turns this off by I still get powernow-k8 messages in dmesg log.
If I start cpupowerd when powernowd is running, the undervolting is overriden by powernowd
Any ideas on how to proceed?
thanks!
