running at modulated clock rate...

[lau0001]

Hi all,
When I run a program for experiments, it seems that the cpu temp. is too high and system reports that the cpu runs at "modulated clock rate".

As this will affect my experimental results (e.g. running time), i would like to ask,
1. what is the "actual clock rate" when the system is running at "modulated clock rate"?
2. how can i prevent this happen ? ( i.e. running at full clock rate )

Thanks a lot.

My system.
P4 3GE
3 GB ram
i865pe chipset

thx !!

run


cat /proc/cpuinfo


might show some info on that.

is it /proc/cpuid will report realtime results?
sorry that i am new in linux...
thx!!

The only kinda clock modulation I know is intels on demand clock modulation, witch make a % of the current running commands halt commands, to keep the cpu cool, i did not know linuc support this. How did you get this turned on?

>How did you get this turned on?
actually i don't set any things, it automatically "turned on" after the installation.
I use fc4 .
