How does the power consumption for a CPU change when it is overclocked? Mainly there are two factors, voltage and clock. How will the power consumption increase when

1. Increasing clock keeping voltage constant?

2. Increasing voltage keeping clock constant?

3. Increasing both clock and voltage simultaneously?

correct me if im wrong but when you

#1 increase in performance, heat, and little power consumption

#2 you wont see any performance increase but you will see heat increase and also an increase in your electric bill

#3 increase in performance, heat, and power consumption

Number 2 is pointless.

In terms of total system power, the difference is not that great.

I was measuring one of my systems. Had a Q6600, stock at 2.4 GHz at a VID of 1.2625 volts, pulled 8 amps through the CPU connector. OC'd to 3.6 GHz at a CPU core voltage of 1.40 volts, pulled 9.6 amps through the CPU connector.

Extra power consumption - about 20 watts.
