AMD Clock and Voltage

After almost a month having the laptop, I have not been able to make my R3000Z laptop utilize the maximum clock frequency and voltage allowed on the CPU. So far, I have downloaded AMD PowerNow Deskboard to monitor CPU utilization, clock and its voltage. It keeps using 36% of the maximum CPU speed. The voltage has been hanging at 1.1 volts. Although, this really saves the batteries alot (90%).

I tried Rightmark CPU Clock Utility. I could pump up the clock and voltage automatically, or by manual. By so far, why the pre-installed AMD driver could not adjust frequency and clock to what I want. I tried to overload the CPU with a lot of processes, but still no change.
