How do i check this? I have a core 2 duo "inside"...
To check:
$ for CPU in 0 1 ; do cat
/sys/devices/system/cpu/cpu${CPU}/cpufreq/scaling_governor ; done
To change:
$ sudo su -
# for CPU in 0 1 ; do echo performance
>/sys/devices/system/cpu/cpu${CPU}/cpufreq/scaling_governor ; done
# for CPU in 0 1 ; do echo ondemand
>/sys/devices/system/cpu/cpu${CPU}/cpufreq/scaling_governor ; done
(set to 'performance' when you need it, set back to 'ondemand' when you
need to save power/battery/etc)
(Tested on Ubuntu-flavoured Linux)
Another thing to be aware of is thermal throttling - if it gets really
too hot then it may slow down to save from melting, in which case the
system logs will tell you (try dmesg | tail, etc). Solution here is
cleaning fans/heatsinks, usually.

Hello,
are you sure that your CPU frequency did not change?
i sometime have this problem : the CPU slowdown to save some power,
introducing audio problem.
i simply put it full speed every-time i use CPU intensive applications.
i don't know how to do this on fedora, but it should be possible.
