Benefit of disabling CPU cores? - LG Optimus 4X HD

Is there a way to limit the amount of cores that can be active on a custom kernel? I am using eprj kernel and am able to disable 2 cores using trickster mod but I really want to try optimus kernel but I can't find out how to disable the cores
Also is there a significant battery improvement if you disable 2 cores and run at 1ghz or is it better to enable all cores and run at 716 mhz?

I'm trying two cores in iodak at 1400 is really smooth but I can't tell anything about battery because I'm starting to try now, only thing I can tell you is that dual core at 1 is better than four cores at 716, why? Some apps runs great at 1 GHz and only use one core, so that app at 716 will work slow and laggy, there is not so much apps that works with all four cores enabled and that apps will work well in two cores enviroments

Thanks I can take a little bit of lag because I really want better battery life and am trying both 2 cores at 1ghz

Also how is iodak working for you? I read that someone couldn't get the max CPUs online value to stick on the latest version

iodaks is working great for me, the V07 version, and yes, i use tegra overclock app and it works great

Is there any downsides with underclocking?

I noticed there is a CPU control in "ROM Toolbox". I was thinking about underclocking it to 1.2 Ghz.
So my question is, are there any downsides with doing this except that the phone getting a little bit slower?
EDIT: Does it matter with what app i underclock? Setcpu or ROM Toolbox..

Im rooted on Speednote kernel.. My bad, should have mentioned it..
Speedmod does not support those tweaks... You need the notecore OC in order to be able to do so..
It's the same whatever app you use.. To change the frequency... Setcpu /etc

I´ve already tried and it is able to underclock, my question was if there are any downsides with doing this..

Why uc it slows performance I would try and find a kernel you can undervolt that will save heat and battery because it useing less voltage

Put it this way. I am running Android 0.8 with the matching kernel (can't remember name) but that UC the graphics I believe and also has options to have min / Max speeds on CPU.
My Max speed is ALWAYS set to 800mhz. I'll be honest, I don't really notice any massive lag or slow down, the odd moment here and there when loading apps or taking a photo, but nothing major.
Battery life is a lot better when underclocked obviously. Give it a try, you may find it perfect for your requirements... it certainly is for mine.

Underclock under 200mhz has some downsides regarding performance/battery consumprion. U should checj the notecore kernel (hydra kernel) and search in there gavin's explanation

Well, i planing on just underclokcing my MAX speed (1.4 Ghz) down to 1.0 or 1.2 Ghz..

Hi Rivan =) ..if you from some reason just want to underclock to 1.0 or 1.2 you can safely do that with rom toolbox or setcpu. There should not be any downsides from doing it in any of those two apps as far as I know, except for that your phone will become a little slower as you mentioned yourself.

Depends on why you are underclocking.
If you are looking for better battery life then you are better off flashing HydraCore (formerly NoteCore) as this is an undervolted kernel, then selecting a low drain governor using ROM Toolbox Pro.

Good CPU app?

Any good apps with profiles and multi core support? Preferably free
Sent from my LG-P880 using Tapatalk 2
I have used Νο frills cpu and antutu cpu master (not free) which supports profiles and its quite good its behaviour. If you're concerned about battery efficiency , i didnt notice any improvement with any of the apps i have used.
Hmm after looking at the frequency states of my cpu I have concluded that there's not much need for any CPU tweaks, just have to wait for jellybean or a miraculous breakthrough that makes custonexus fully functional

Written elsewhere,people say that even the lg launcher consumes battery compared to other launchers.Try testing some.

Overclocking the GPU [Poll]

Hello!
Since there are some kernels that support GPU overclocking:
1. What GPU clock do you use?
2. Is your GPU undervolted?
3. Do you see any performance boost with overclock? (eg. benchmark or gaming)
4. Is your battery life the same as before? (or better/worse)
Another thing, does anyone know if you overclock our Nexus 7 GPU - does it stay there or it has no effect?
Have fun!
My example:
1. I OCed my GPU to 520mhz
2. mV values at 520mhz is 1175
3. My benchmarks are the same - I think I can see some performance improvement while gaming (might be placebo)
4. Can't really tell
i overclocked my gpu to 500mhz
with an undervolt of -50mv
You should also list what kernel you are using

Running M-kernel a40 with GPU at 500 no under volt, I see slight improvement in graphics benchmarks but you won't get much because of the RAM bottleneck. My battery is only worse if I do a lot of gaming

Don't use 500. Use 446, 484, 520, 600, 666, or 700. Complicated reason but trust me.

Ha thank you sir, I almost forgot about the "proper" values. I know the basics of why it needs to be those values
Sent from my Nexus 7 using xda app-developers app
600mhz, 1300mv, testing and searching for the lowes and more stable voltage for this frecuency.
Oh, and Metallice, why we need to use 600, 666. 700 or the other values? And, how much voltage the cpu and gpu on this device can handle?
Edit: 520 mhz using faux kernel ultimate, I don't know the voltage on his kernel.

[SOLVED] - [Q] CM 10.1 RC1 - disable cpu cores ?

is it possible that i enable only one core and disable all other cores of my cpu ? How???
I'm on CM 10.1 RC1 On v20a official - rooted - unlocked - with CWM recovery
You can do that by using an app called Tegra Overclock for example.

it doesn't have optimus 4x in the supported list
Our phone is supported, don't worry. We got Tegra 3 processor. I am using it daily to improve performance (mainly in games to overclock GPU and to REALLY force all 4 cores to work).
Here's a couple of screenshots that I just made to show you.

Great! Np, glad I could help.
I have a question after force to use one core with this program how I can control the heat problem and the lag on the jb besides the drain battery problem? Thx for ur help

[Q]How to enable only two cores? (CM ROM)

Hi all.
Dont know if this is a stupid request
I am on CyanogenMod based ROM and i want to save battery (maybe) disabling some cores of my O4X...
I read this
http://forum.xda-developers.com/showthread.php?t=1804461
but not working on CM ROM so...
I ask you!
I read also this 2 threads but I dont know if they are only for htc one x
http://forum.xda-developers.com/showthread.php?t=1630200
http://forum.xda-developers.com/showthread.php?t=1652136
There are tricks to enable only 2-3 cores or something like this?
For CyanogenMod of course!

Hi, you could try with this nice app called Tegra Overclock. I've been using it for quite a long time now and I really like it. It's very simple and you can REALLY set how many CPUs you want online + there are also some other options for OCing etc.
Oh and btw, I just tried that app from the HTC One X thread that you pasted and unfortunately, it doesn't do the job. :/

No problem. I hope that It will help you with your battery life.
also cpu tuner and trickstermod do the job pretty well. If your aim is to save battery check cpu tuner out
But seems that trickster mod dont save those settings for me...
Multicore Power Saving
always set to 0
Max Active CPU core
always set to 1
No way to fix them (various rom and kernel tested).
AND
Seems that tegra overclock fired up my CPU (CPU never goes under 1000 Mhz but always on max)
my phone after few minutes reboots in bootlop cause the temperature reached !
I reinstalled the ROM!!
LOL experience!!:banghead:

You need to set up min/max cpu that way u wont be stuck on max cpu speed and overheat your phone.Tegraoverclock is fine but i am kinda used to SetCpu app.Download cpu spy from market and watch deep sleep that way you will know whats going on with cpu all the time.BetterBatteryStats are fine too.
