Ubuntu only Reports 1000 MHZ

I have an AMD Athlon X2 64 6000+ and it wasn't throttling up past 1000 MHZ so after reading a lot and some experimenting I found the solution.

This will tell you your current MHZ
cat /proc/cpuinfo | grep "cpu MHz" | head -n 1

This code will tell you all the possible MHZ frequencies your CPU supports


cpufreq-info
As it turned out cpu freq was not installed on mine so I had to install it.

sudo apt-get install cpufrequtils

Now when I use the CPUfreq-info command I get the correct stepping for my CPU.
You can also add CPU freq to your panel as an applet by right clicking on your panel and selecting it from the drop down list.

CPUs which need to switch frequency at the same time: 0 1
hardware limits: 1000 MHz - 3.10 GHz
available frequency steps: 3.10 GHz, 3.00 GHz, 2.80 GHz, 2.60 GHz, 2.40 GHz, 2.20 GHz, 2.00 GHz, 1.80 GHz, 1000 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1000 MHz and 3.10 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 2.40 GHz.
cpufreq stats: 3.10 GHz:2.25%, 3.00 GHz:0.64%, 2.80 GHz:0.32%, 2.60 GHz:0.42%, 2.40 GHz:0.40%, 2.20 GHz:0.32%, 2.00 GHz:0.32%, 1.80 GHz:0.42%, 1000 MHz:94.92% (33)
