My AMD Phenom II X6 1045T has a normal maximum frequenzy of 2.7 GHz but can boost up to 3 cores to 3.2 GHz if needed. My BIOS is showing correctly 3.2 GHz as the maximum frequenzy. Here are some informations about my system:

sworddragon@ubuntu:~$ uname -m
x86_64
sworddragon@ubuntu:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
2700000 2000000 1400000 800000

I have written a script which uses 100% of cpu time for 1 core. Theoretically this should force the processor to go up to 3.2 GHz on this core. In the attachments is a log which shows the output from /proc/cpuinfo and top which shows that my processor is still using just 2.7 GHz.
