Are you running a frequency scaling daemon (cpufreqd or similar)? Try doing something CPU intensive in Fedora and running the cat /proc/cpuinfo and see if the frequency is different. See if you have a directory /sys/devices/system/cpu/cpu0/cpufreq/ with "files" in it? If so, cat some of those files and see what they have in them. Jonathan
