I have known that some phones have kernels surporting increase CPU voltage(such as htc G7,ME525).In this way,we can make the CPU running at a faster speed smoothly and stably.The default CPU frequency of P500 is 600MHz and the frequency is too low for performing some heavy works.So,i want to improve the voltage of CPU to make the heavy woks more easily.Is there anyone can help me?
Can we make a kernel satisfying the requirement
Can we make a kernel satisfying the requirement or there is another way to resolve this problem.
What is overclocking?
Overclocking is the process of making a computer or component operate faster than the clock frequency specified by the manufacturer by modifying system parameters. One of the most important techniques is running at a higher clock rate (more clock cycles per second; hence the name "overclocking"), but other parameters, such as CPU multiplier and memory timings, can also be changed and would be considered to be overclocking. Operating voltages may also be changed (increased), which can increase the speed at which operation remains stable. Most overclocking techniques increase power consumption, generating more heat, which must be dispersed if the chip is to remain operational.
Advantage:
Higher performance in games, encoding, video editing applications, and system tasks at no additional expense, but with increased electrical power consumption. Overclocking can extend the useful life of older equipment. Adding noticible response time for multitasking and powerhungry applications and games.
Disadvantages:
Overclocking if it's not done with moderate rate can be very risky and potentialy might permanantly damage your device's hardware, plus it can cause a slight battery drain. If it's done correctly then you're good to proceed.
Undervolting :
Undervolting is reducing the voltage of a component, usually the processor, reducing the voltages of each step less than the original stock voltages.
Advantages:
Increase of Battery life.
The heat that come from the processor reduces.
Disadvantages:
Undervolting if it's applied correctly then it's good, Hard undervolting might make the device unstable and potentily will lead to bootloops and freezes.
CPU
Maximum clock that could be applied on The Galaxy S4 is XXXXmhz and the minimum is XXX mhz . I will add the stock clock values as soon as possible.
More to come asap !
SERIOUSLY?
A guide about overclocking when you don't even know what CPU the specific models will be getting?

I as well, think that this is a bit strange...

and probably the S600 version will not be OCable its already has throttling problem due overheating ( + its an OCed version of S4 pro )
Weird thread
sent from an Galaxy s3 GT I9300
Running perseus kernel 33.1 , XELLA 4.1.2 leaked build
forum.xda-developers.com/showthread.php?t=1784401
Dont click,you might regret , I won't be responsible if you brick ur head
jus sawed this guide tosee whats safe minimum voltage and other stuff! better to change title or a how to (i already know btw )
lol this is horrible! where's guide to udenervolt? i also underclaockd m cpu to 1GHZ that feels a lot lot colder and still freaking fast! even think more stable! also i wannt to underclaock the GPU too and also udnervolt it anyone knows how? i got i9500 octa
You need root for this and probably need a way to disable the CPU clusters.
What is the Geekbench 3 results for the following?
Only A53 cluster with performance gov (locked 1.5 ghz)
Only A57 cluster with performance gov (locked 2.1 ghz)
You need to monitor CPU utilization in order to know that only the wanted CPU cluster is being used.
Core 1 - 4 is A53 cluster
Core 5 - 8 is A57 cluster
EDIT: when running Geekbench 3 normally, can someone check if all cores 1-8 are used by Geekbench 3 for the multicore result by monitoring utilization of all 8 cores during the benchmark. If all 8 cores are used there should be vey high % utilization on all 8 cores during some parts of the benchmark.
Thank you.

Why?
Short version
I'm interested in the CPU performance of both clusters separately because I manage my phone performance (Note 3) with the help of
Multicore CPU Control PRO, and SetCpu with profiles enabled on screen off/on and certain applications.
I don't find the stock settings responsive and smooth enough so I adjust them.
Recently I was in an argument with a forum member.
He claims that undervolting will make cpu go overheat instead.
Is the statement true or false?
undervolting doesnot overheat as the processor will not get that much amoumt of voltage to go to temperature that are away from normal. just apply physics here. no over heating will happen. but your device can end up in bootloops as the proceasor will not get the power to go to higher hertz to perform operations to open and loade android platform
Hey guys I am using kernel auditor
Want to know
1)the profile to get the max performance regardless of battery
2)profile for normal multitasking but with higher battery saving capacity than stock arrangement
3)which is better 4 Cores and then restricting to 1.5ghz (or any other frequency which u would seem for the power saving) or switching off permanently and then setting the frequencies at about 2 GHz
