How can i set my voltages so they can save for boot?

I use overclock widget

No i dont wanna overclock.
I just wanna know how i can get my voltage values to stick on boot.
Thanks anway

I'm taking a look at the SetXperia configuration and it modifies the following file: /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
First column are the frequency steps in hertz and the second column is the voltage for each step in mV.
You can use SetXperia too!

I know that, but the values dont save for boot.
Thats the problem.

Maybe you should ask in the kernel thread because that's a kernel feature. Wedgess probably will know the answer.

I'm on LupuS kernel as well. The Perm Activate button on Oc/uv beater 1.7 seems to work for me.

Thanks everyone, got it working.

[Q] How to use incredicontrol?

Hello All,
Can anyone give me a proper procedure of how to use the Incredicontrol app? I downloaded the app from the market and checked the posts on the forum. I read it shows two lists with the + & - signs to set the min and max temp. but in my app I can only see the one list with + & - signs and I am not able to get how to set the temp. Please help.. I have attached the screenshot.. Please go through it...
I am with XperiaMod6 with DooMKernel v19.
to undervolt, use that - for All.
it decreases 25. do it again and apply to see how far you can go, yet stable .

Sorry I didnt get u...
I knw that it is for undervolting. I just want to know y my app looks different than that specified on the forum? What do all those nos. mean? are those different frequencies?

This app shows you voltages each frequency.
Why different....its simple and working app.

I have tried it...
Try undervolting it with -100 on all... That is stable on mine and then apply the settings

Better try -50mV at first.
Mine was stable from -100mV to -200mV and after 4 months with oc I had to go back to -75mV to -175mV.

Yes -100 and no overclock works great for me.... And my battery life is pretty good with Xperia mod v6 and doomkernel v19 and baseband 64 + patch but try with -50 to get started :-D

Im heavy user and already over -50 is unstable for me
Does anybody have any idea how to setup 2 or more voltage profiles?
ETC: Screen off voltage profile and screen on voltage profile
Makes no sense, CPU can't handle different undervolting when screen is off or on.

But why not?
If phone can handle different frequency...why not different voltages.?
If i can change voltages, then would be nice if screen off takes more -25 all frequency and if screen on then +25 to all
Why only "incredi control" voltage app works with Neo? It think wiht Arc too!?
Ummm I've been wondering about this... for a little while. Now I'm trying Incredicontrol and I'm undervolting my Arc -100mv. I'll run with that for now and see what kind of "possible problems" I may encounter if any.

But you need to reboot for the volts to apply, so for that you'd need to reboot every time you want to use your phone ???
There's a setting that sets it on boot.

Enable undervolting.

So I have finally got round to taking control of my Play. Unlocked my bootloader, rooted, applied DooMKernel v14 and now have Gin2JelllyBean rom.
I've already managed to squeeze a day more battery life thanks for SetCPU down clocking while the screen is off. Now id like to look at undervolting.
From what I read, there should be an undervolting option active in SetCPU but it's not there. I thought DooMKernel supported this, so firstly I just wanted to ask if there is anything I need to do to activate it or if might have gone wrong somewhere?
Thanks in advance.

I have SetCPU too and it doesn't let me change the voltages. I am using IncrediControl for changing them, and it works
OC/UV Beater2 v1.7, allows setting voltages in an init.d script, so there aren't any unnecessary services running on boot
Thanks for the suggestions guys I will check them out.
Still confused why I can't use SetCPU though.

Be careful u dervolting, can actually decrease battery life. Never set undervolts to run at boot.

[Q] Overclocking P930 / P936?

Ive done a lot of seaching but cant seem to find the answer....
I have a P936 running a slightly modified version of AT & T's ICS P930 ROM and Kernal.
Ive just finished setting up everything but want to overclock and dont know which kernal to choose.....
Any help? My software version is V20c.....
Use wind kernel, you won't be disappointed. Just make sure you run through the whole thread for the p930/6 version. I'm now using it on a clean v20f, couldn't be happier.
Sent from my LG-P930 using xda app-developers app
Awsome, thx man! Im rockin at 1800MHz now
But now I also want to OC the GPU, know any good app for that? I cant seem to find one...
Faux123 kernel tool is designed to work with windkernel and allows gpu over clock and many other useful tools for kernel tuning
Sent from my LG-P930 using xda app-developers app
Faux clock lets me set the GPU's 3D clock speed to 320MHz and thats where Ive got it. But the Wind kernal is also supposed to allow overclocking the 2D speed. How do you do that? Cant find any setting for that in the faux app. They say something about echoing something somewhere in the Wind kernal thread.... Any help?

Use a terminal emulator app and run the commands listed in that thread exactly as written in the thread to overclock 2d

Ok but then will the setting stick or do I have to set it again via terminal every time I reboot?

Gpu overclock

Hello
I'm currently using a note2core asylum kernel which supports both cpu and gpu overclocking. My question is, how do I go about overclocking the gpu? Any help will be appreciated.
Sent from my GT-N7100 using xda app-developers app
Don't need that overclock note 2 is an excellent phone more than a phone...my oppinion
Sent from my GT-N7100 using xda app-developers app
I know. Its all for.research purposes anyway
Sent from my GT-N7100 using xda app-developers app
I'm not sure if note2core supports stweak but that's the app you need to over clock. There are other but I prefer this one. It will give you a maximum slide to 1800mhz and also tons of other features such as adjusting charging amp, under volting including for the gpu as well. There's not much to know about over clocking as its pretty straight forward but you can change the xpu governor and the number of cores you want activated and how you want them to activate based on your usage. Under volting will help with both temperature and battery life although I find the changes almost insignificant, but you should try it out. If you want to undervolt start with around - 25mv.

You are talking about cpu not gpu
Sent from my GT-N7100 using xda app-developers app
Okay it's not that different. Just over clock it and undervolt at the same time to - 25mv and then download an app called stabilitytest from play store. Run it for 10minutes and see if you get any error. If not then further lower the voltage to - 50mv. But usually - 25 is good. I noticed that anything higher clocks peed than 5xxmhz starts causing error and graphic glitches.

A CPU question

I want to over clock my phone and under clock it when I'm not using it to save battery life is there anyway to do this I've tried a few apps and they didn't do much
What is the lowest clock rate for the phone bc on the apps it puts it at 384
Thanks for the help

The lowest safe rate would be 384 but you would be a lot better off
to get the "JuiceDefender" app from the play store.
It has a lot of features including auto cpu frequency and you can set it up
so it automatically handles all options needed for the very best battery
savings modes without sacrificing performance...
My personal opinion which is not worth much is NOT to mess with
manually over clocking, under clocking or volting but instead use a
true and tried app like JuiceDefender to do all the work for you.
Check it out at the play store.
Thanks I'll try it out

Hey i got a question about CPU. Im running wicked rom with Deviant Kernel. My max and min freq keep changing. My kernel allows me to overclock to 1944 but i set it to 1620 and min at384. im using smartsassv2 and cfq but it keeps making my maximum 1350. no matter what i change the gov. to or the max. I reinstalled rom and and the kernel seperate. to see if it would make a differecne and same results. Please Please Please help me fix this
I'm not an expert but I think I can some what help you. Are you toggling the set on boot?
Sent from my SGH-T999 using xda app-developers app
You need to install a custom kernel and possibly a custom ROM.
Then you can overclock/underclock to what your kernel supports.
I've seen kernels that allow min at 94 and max at 1944.
