[Q] Undervolting on DoomKernal - Xperia Play Q&A, Help & Troubleshooting

On doom's post, it says he undervolts, but in the changelog, it says he removed it.
Does this mean I cant undervolt on the DoomKernal?
And if I can, should I?

Doomkernel does provide a lot of advantages, and with SetCPU you'll be able to undervolt (I'm doing the same). But only do it if you actually know what you're doing.

I cant find the undervolt settings on SetCPU.
I tried downloading an undervolting app, but it says I am using a kernal that doesn't support undervolting.

This app works perfectly for undervolting my PLAY, OC/UV Beater2v1.7. IncrediControl also works I believe

when i undervolt even by .25 my phone just freezes. any ideas why?
sorry to hijack thread.

Anyway, I downloaded IncrediControl, but I'm at a loss on how it works.

Overclock Help

Other than SetCPU apk, Is there another apk that will allow me to overclock on my evo????
There are a couple in the market. Overclock widget is one of them
We're comin from a pure power source.
I personally like SetCPU the best

You are probably aware of this but I'll throw it out just in case... You also have to be running a kernel that allows overclocking.

Yea, I think this is my problem, it won't go past 998400mhz. It says you can disable Perflock, but that doesn't do anything.
So is there no way to overclock with 2.6.35.10 htc kernel?

DUMB QUESTION...I think

So on the miui.us.us latest after installing tiamat kernel everything works great...but do I need to install something like setCPU(which I would like to avoid) to set clock speeds etc etc. I'm pretty sure you do seeing how I can't find it anywhere in settings. I know in roms such as mexdroid and the like new kernels replace "performance settings". So I'm thinking I need to use setCPU.
Thanks for any help given

I'm not completely sure about that specific kernel, but its a pretty good idea to run SetCPU if your ROM doesn't include CPU settings.
For example, if the kernel you installed OC's up to 1.5ghz or something, you may prefer to run at a lower frequency. SetCPU is probably a good idea. Also, if you want to run at 1.5ghz you're going to need SetCPU profiles for heat and screen off, etc.

Thanks for response. I know all about setCPU, I just don't like it. But yeah looks like that's the only option. Although miui.us seems to be clocked at 1GHz so I think I'll just stick with that.
Thanks again...and tiamat kernel works great on it

Good. Yea I don't like setCPU either. I use the built in controls in CM7. If you're happy with the stock clock speed and don't have issues you won't need to use it.

[Q]How to go under voltage?

I keep hearing people say they uv -xx number to save battery, how do you do that?
You can check the kernel thread you installed from. Usually use echo command and point to vdd_table. If you don't understand what undervolting is, you may not want to do it. It can cause issues if you undervolt too much. It can save battery life, but i would suggest using setcpu, you can find a free copy on xda, and setting profiles, like screen off, in call, etc., to lower values. I would say, stay above 300MHz for min. and clock down the max. Min are: 384-540 for screen off; 384-540 for in call. also, with some roms, you can set the main value, on the first tab, to a lower figure in the max column. I don't charge my phone everyday anymore.
Thanks for the detailed info. But I heard there's an app that does uv?

Luckily, I do use Juggernaut.
I installed fauxclock but I don't see a way to under voltage? I only see the interface to set CPU clock. Am I missing something here?

Ah ha!!! I see!!! Thanks!!
I've used up my "thanks" for today but I'll definitely come back tomorrow.
What is the uv number I should generally set to save battery but not have the phone freeze?
If I set it to negative too much and the phone freezes, I just reboot the phone and re-set the number to a higher (less uv) value?
it's different from phone to phone, you just gotta try it out and see.. i UV mine about 100mv under stock at 1.51ghz

Mine can do 100 also
I can only go -62.5. Anything over that will freeze the phone...
How come every phone is different in this regard, does this mean my phone is "born" to consume more battery?
Thought I saw posted somewhere here not to use SetCpu on our phone? FauxClock always FC's on me. Running Jugs overclock on rooted/flashed T-Mo SGS2.

[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 .

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

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.

[Q] SetCPU - Voltages won't apply

Hello, I have just got SetCPU 3.0.9. I set my voltages then clicked "apply" it then said unfortunately, SetCPU has stopped. I have tried many times and it will not work. Please help!
mind if i ask why you're using setCPU when you have ktoonsez kernel/KTweaker app installed? i make my freq and voltage adjustments there

I heard setCPU is the best.
i'm sorry i dont have any setCPU advise to offer other than possibly uninstalling/reinstalling it. i'll check into it though.
imo, the software included by the same dude that built the kernel is the logical choice for adjustments.
it has done everything i needed it to without any problems.
I have to agree with BeerDroid. If you're using KT's kernel, I would strongly recommend using Ktweaker to modify kernel settings (gov, scheduler, voltages, etc.)

One question, how do you save the settings on boot manually? I don't like how it sets it after a certain amount of time.

You can have it to set on boot automatically, a timing of your choice, or not at all. It's in the main UI labeled "set options on boot."

After being a loyal setcpu user for multiple years, I found that system tuner pro is a much better app.

Its best to apply after system boots up, than alter init.d scripts. This way, I'm case of any malfunction (as in too much undervolting), deleting the app using adb is sufficient.

I hate how you have to drag it.
It won't apply. I have a feeling that KT747 is causing the issue. Every system tweaker I tried would not apply.
Do you guys suggest re-installing KT747?

It may help. Also, be sure to make sure you don't have another kernel tweaking app trying to make changes as well. If you have multiple apps trying to run settings you could run into issues. What exactly do you mean when you say that they wont apply?

In SetCPU (don't have anymore) when I pressed apply on voltages, it stopped working. With KTweaker, I press apply then go back. If I go back in, the voltages are back to defaults.
Found several issues. Apparently, my phone was not rooted properly. When installing, it asked to root, I said yes. Now I also noticed the new splash screen. Hopefully it works.
