How safe is overclocking?

I am experiencing lag on real racing 3, on high graphics. If I overclock to say 2ghz on cpu, will the tablet be stable enough? Should I undervolt ( and does it actually make any difference on temps)? I want to overclock but not at the cost of huge battery drain, can some1 recommend me a good kernel and some stable oc steps?

Are you running a custom ROM and kernel? I play RR3 daily and have NO lag. AOKP PUB ROM with ktmanta kernel, at 1.7mhz CPU and GPU OC to 720. Runs great.
Most OC is safe, issues are really with battery and overheating. I've run for long periods at 1900 just fine.

So there's no way the tablet will melt down because of the heat? Does warranty cover that? Assuming they don't know it was overclocked, which they couldn't because the device would be dead, right? I guess they don't bother to repair it and see if it was rooted.
LE: btw did you manage to safely undervolt? Even a -5 gives me reboots on most freqs.

Any time I try to use the app from the store to set the graphics mode it causes problems. Running RR3 without it works fine.

Take a look at the KTmanta thread. KTmanta is a great option for what you are after, he notes and codes distinctions between clocking and thermal protection, plus unless you lock the settings, they will reset at reboot!
If you tell Google you messed it up from some sort of tinkering, no - they won't help you.

I am assuming you must be using the KTmanta kernel right? I thought it was the only kernel right now that allows for user control undervolting. Trinity has a static -50mv value set on all frequencies by default. You should be able to undervolt just about everything. Getting lockups at -5mv lets me think there is something you are not doing correctly
EDIT: threw the quote in so its less confusing

Yes, the kernel
Edit: oops thought you were asking me, I see now I was confused.

Is it possible to disable 2 cores on default kernel or any custom kernel

Currently running 4.4.2. stock with ART enabled. This combo suits me well in terms of fluidity and everything works great. Now I would like to have an option on disabling 2 cores to extend battery life. is there an app to do so on stock kernel and is it even possible to do it on some custom kernel? If there's no option to do it on stock id like recommendation for custom kernel that works on stock rom and would enable me to do this via some app.
And id like that ART can stay enabled.

try a custom kernel like ak or hellscore
after that disable 2 cores using trickster mod/kernel specific app

Yes, Darkrai is right. Test a custom Kernel like AK, Matr1x, Hells core, Franco or Faux.
You can easily flash the zip via recovery. After that, you should download a Kernel App like Trickster Mod or Kernel Tweaker from the Play Store to customize the whole kernel, gpu, cpu, govenors, schedulers (2wake) etc. And also the cores of the cpu. But you need not to stop 2 cores, you only have to underclock the cpu, so you have all 4 cores but they, for example stop at 1ghz, which save battery at all

I don't really think it helps your battery life (a lot).
More cores at a lower frequency are more power efficient than less cores that have to work at a higher frequency to get the same job done.
And hotplug is there for a good reason, if cores can sleep they will.
Or does anyone have personal experience where it really helped a lot?

I don't understand why people complain about battery life. They say 1 day is not enough, well it is considering their usage.
You can easily pull of 2-3 days without playing games. The problem is that everyone spends like 2-5 hours looking at their phones every day!
On topic: If you want to have performance and fluidity with 2 cores, you will save 0% battery because cores will work on higher frequencies. Just try not to using your phone 24/7

Short answer: No.
Long answer: No. But you can undervolt them (All 4 of them at the same time).

Try Franco kernel ... it by default supports dual core mode ... moreover u can play with hotplug values according to need

You can using a custom kernel, lots include the ability to but the best implementation is faux's eco mode which is found in Faux's kernel and Ak kernel.

I have tried semaphore kernel with 2 cores only online.
No big difference with other custom kernels where I was using all 4 normally. And the worse about 2 cores is the lag at many applications.

Great, its the kind of discussion i hoped to start. My logic was that n4 might have enough cpu power for surfing and casual usage with 2 cores only. So if i disable another 2 i might extend battery life.
Its great some of you tried and show me that my logic was flawed
Now undervolting. I suppose that i cant fiddle with stock kernel and undervolt cpu? Any recomendations for custom kernel. id like it to be as similar as stock, with undervolting feature enabled.
And are there any real gains in undervolting?

Many custom kernels support uv like Franco, hell God etc.
Uving is offering a little cooler cpu, which means more time till thermal throttling to start.
Let's say it helps system in general, but not something to notice in big way.

Undervolting brings much more than turning off cores. As a side effect your phone won't heat as quickly under heavy load.
What will save you a lot of power while having the phone awake is screen brightness. So you should look for a clever auto brightness solution or, like me, use a mod that let's you adjust brightness by swiping the status bar. I keep my screen dimmed to the low at all times and only make it brighter temporarily if I am outside and the sunlight blinds.

Rooted phone... keeps overheating?

I just got my s7e yesterday. Found the guide on here how to root it. I did and it started having overheating issues so I downloaded kernel adiutor and put it on "on demand" as I saw posted somewhere else. This seems to work BETTER but my phone still keeps overheating frequently.

My AT&T one was, too. I went back to stock. Faster and cooler (temp). Just gonna wait for a fix.

Yeah it doesn't matter what you set it too, it will overheat more then the stock.

my phone doesn't overheat at all. stock kernel uses interactive governor not ondemand. and you need to use an app that supports big.little CPU cores like kernel toolkit or ex kernel manager. set your big CPU cores to 2.1GHz and your little cores to 1.6k GHz. if you don't know about all this you guys probably shouldn't be rooting in the first place.

I was overheating also on pb6 firmware. Flashed pb8 and re-rooted, used kernel toolkit to set interactive and cpu cores to there min 300 something and 1500 for small and 2100 for large. Then flashed tekx. All is good now. Battery life is nowhere close to stock still.

This is with using EX Kernel and big.little set to interactive. There is a problem with WiFi and some gaming that will heat this phone up hotter than hell itself.

And what firmware are you on? Did you also try flashing tekx? My phone doesn't heat up at all and WiFi is fine. Using pd8 and tekx. I had overheating but it's gone after a full wipe and flashing pd8 prior too rooting. It sounds like you just need to try again. I had problems also, it took a few tries.

If you use your phone for gaming you will see how much the phone heats up. If your using it from normal non heavy things it will be fine.

Well after switching to ex kernel, using TekX ROM, greenify, and L Speed, my phone is running almost perfect with great battery life.

Ex Kernel is an app that you can get from the play store.

That's a ****ty response........remember when you were a noob? There was a lot you didn't know....don't bash people on the forum for trying or questioning what to do. You're a senior member. You probably should act like it and give the proper advice rather than saying one "shouldn't be rooting in the first place" I need to wear a condom just reading your post because of you being a **** on the thread.

...and there is slight heating, and major overheating when playing heavy games like dead effect 2 when you root. Even after the scripts and kernel tweaks. It's the engboot. Likes to be warm I guess
It's the trade off for now if we want root..

[REQUEST] Overclock for GT-I9060I

Hello everyone, I open this topic to ask the community to create an overclocked kernel for this phone. I will be very grateful to you. :highfive:

There is already a kernel that upgrade the minimum ampere limit, allowing the phone to charge in fast charging. You can find it in DotOS rom, but it's only for nougat roms

I may say that overclocking may kill your battery and heat up your device making it unstable
my first pc that i overclocked was a failure because it MELTED THE FLIPPING MOTHERBOARD.
Anyways I don't think this phone is overclockable because 1.2Ghz may be the maxed out speed for this cpu or for safety reasons
if your looking to process 3D games with less lag you will need to overclock the gpu whiich i have no idea on how to do this.
Anyways @sm-a510f IS right the kernel for dotOS indeed speeds up my charging speed to 200-300% compared to stock rom. I mean I can just sit there and watch the phone charge from 20% to 60% in minutes

Thanks anyway .I will try that

I might be late but try the Bossurt kernel Dev4Pref made. its pretty nice. CPU overclocked to 1.5 Ghz

Over/under clocking app?

Can anybody recommend a working app to change to power to the CPU on the LOS 17.1 ROM (rooted with magisk)? I would like to be able to squeeze out some more battery life, but all the apps I used to use years ago don't seem to want to load, or if they do load, they don't do anything when changing settings.
And is there a better kernel to flash which does support under clocking if the current one is just incompatible?

I think the stock kernel doesn't let you underclock, there is a custom kernel called firekernel, but idk if it has underclocking, but it has great battery life and more governors. Im trying it out right now and the phone doesn't randomly get hot for no reason anymore. I haven't tested games yet tho. Heres firekernel https://forum.xda-developers.com/galaxy-a70/development/kernel-custom-kernel-galaxy-a70-t4174819 and you need magisk installed for firekernell
