[Galaxy S III General] HappleBR:
Hello guys, after many tests on stress CPU, today I decided to post my voltages, they are very stable and low power consumption, so test and post your results! :good:

Read these articles before making any kind of change in voltage:

This table is used to adjust the ABB according to each frequency, here we have the range of maximum and minimum possible in FBB (green) and RBB (blue).

"Forward Body Bias (green)

A FBB is defined when the bias of the gate voltage minus body voltage is positive, meaning the gate voltage is higher than the body voltage. This has the effect of reducing the threshold voltage. By reducing it, you can achieve lower voltages, or be able to clock the transistor higher. However the side-effect of lowering the threshold voltage is that you are sacrificing power leakage, meaning that the lower the threshold voltage becomes, the higher leakage current in the transistor becomes. This leakage power rises exponentially with a linear lowering of the threshold voltage. This is what is called static transistor leakage.

Reverse Body Bias (blue)

A RBB is defined when the bias of gate voltage minus body voltage is negative, meaning the gate voltage is lower than the body voltage. it has the direct opposite effect of FBB, it raises the threshold voltage thus you would need a higher gate voltage for switching, but however you also dramatically decrease static leakage."

Formula for calculating the ABB = "Voltage Frequency - ABB = FBB(if a positive result) or RBB(if a negative result)"

Change the voltage of "ABB" aims at to reduce or increase the energy "sent" to CPU depending on each frequency, so ABB is separated into 4 blocks of frequencies.

1 - 200MHz] = This is the frequency of the lowest energy consumption, it is used when the device is with the screen off. We use RBB in this frequency to minimize power consumption.

(at low frequencies is not re-quired a lot of energy to operate)

2 - ..800MHz] = These are the frequencies of average power (300MHz ~ 800MHz), the ABB should continue RBB to avoid excessive consumption of energy.

3 - ..1600MHz] = Frequencies high energetic consumption (900MHz ~ 1.6GHz), ABB should be FBB, how these frequencies require greater energy demand to work with it should.

4 - ]1600MHz... = Frequency of high energetic demand (1.7GHz and 1.8GHz), few devices can reach this level of overclocking, however if you can, always ultilze FBB!

Attention!

Each CPU has limits, we aim to reduce or increase the ABB is to create a

balance of power and performance.
