Hi guys,
I've got a Galaxy S3 via Rogers, rooted, running the rom Triune II, I haven't messed around with custom Kernals (tbh haven't figured that out really), I recently installed SetCPU to overclock my S3 for running graphic intensive/slow loading games like Asphalt 7, etc.
So far for that purpose it's been amazing, the games literally open twice as fast. I've setup SetCPU for a variety of CPU changes, ie. higher speeds for graphic intensive games, lower speed for screen off while charging (ie. overnight) and it seems to be working great.
My questions are:
Can "overclocking" damange my device? Ie. I know that obviously overclocking shreds through battery life, but is playing a game at the top speed available on SetCPU (1512 Mhz) bad over a prolonged period?
Also, am I not reaping the full benefits of over/underclocking having a custom kernal installed?
Also...nother totally n00b one, if the S3 is capable of reaching the "overclocked" max speed, why doesn't it in the stock ROM? I just don't quite get that....is it because the battery life would be terrible and people would blame Samsung for it?
Never had a issue overclocking. And I've overclocked every phone I've owned beside the iPhone.
As far as how much better it will make your phone it depends. Depends on the rom too. I've noticed better benchmark results yet not always better real world results.
I use it more for the ability to underclock, and overclock when necessary.

a little off but do you know of a way to measure the temperature of the phone (when you overclock/or even normally) ?
My phone does heat up sometimes
For over/underclocking there must be support for it built in kernel ! So if stock kernel doesn't support it you cannot probably change frequencies without changing kernel on stock Rom !
Also read the kernel's documentation - stable frequencies will be listed there - jumping back and forth these frequencies won't cause any troubles apart from the obvious battery drainage depending on your settings

Yes overclocking can damage your cpu from overheating, some even believe it may reduce the lifespan of you cpu.
If you are running 1512 max you are running stock mhz, that isn't overclocked. You cannot run a stock Sammy kernel and overclock it unless it's been recompile..to be overclocked.
I recommend ktoonsez kernel it can be overclocked to 2106mhz and underclocked to 96mhz. As well as undervolting support which is pretty much essential for overclocking because an undervolt will make your phone produce less heat by lowering the voltage your phone requires when running.
To answer your second question, yes you are not reaping any benefits without a custom kernel, this is evident.
To answer the last. The stock kernel is maxed at 1512 because that is the best mhz for the STOCK Sammy kernel performance and battery wise. Also its possible that overheating happened when they set the max at higher mhz during their tests.
Some good general knowledge if you decide to overclock, would be learning how to and what undervolting does for your phone. You can read up on that here:

Make sure you download the right one for your rom!
If after reading about undervolting and installing kernel and would like some safe undervolting and gov/scheduler settings let me know! You can also find many other settings here:

Sorry that kernal thread is a bit confusing.
Does that Kernal only exist for the stock carrier ROM and CM?
I'm using Triune II, if the kernal doesn't exist for that ROM then I take it I have to change ROM's?

No. Triune is a TW based ROM. Therefore, you need to download KToonsez TW kernel. Keep in mind there is a ICS TW kernel, and then there is a JB TW kernel.
There are other kernels out there. Faux123 has a good one. It is capable of OC to 1.8Ghz, I believe.

Im stone stock right now. Do you see an actual improvement in apps that need the extra O/C HP? I have one game I bought that seems to be a little choppy at times, 9mm HD, and Im not sure if its the games coding, the fact that it maybe having a problem with ICS, or just not enough hardware HP to be fluid.
I OC'ed when I first got the phone but quickly dropped it back to 1200. This phone doesn't need overclocking and if you are noticing lag in games it is most likely due to poor coding by the dev for either ICS or dual core phones or both. If it is lagging on a 1.2 GHz dual core and it is our hardware think about people running it on the Inc 2 with a 1 GHz single core processor and basically last years tech. Our phones should be fine to run most if not all games for about a half year or maybe a year before OCing will really be needed.
Why don't you just do it and find out? It's really hard to tell because no kernel is a stock kernel with 1.35 GHz / 1.4 GHz.
All these kernels featuring OC have additional features which means that it could be the features/tweaks that are fixing it rather than the OC itself.

Well,...Im just pretty content with how it performs in every other aspect, except for this one game bugs me a little. Ive been ROMed and O/Ced on this not too long ago, and TBH, theres always some sort of little thig that turns me off about it. A spontaneous reboot here, a F/C there, and I find myself going stock again. I would do it in a heart beat if it didnt mean having to set every last detail back up again when I unlock the phone.
And yes, being virtually OCD about this phone sucks, lol.
I have a question as well!
For those under-clocking or using UV kernels, do you see a noticeable improvement in battery life? I have a GSM sock GNex and the battery life is atrocious.

Should of unlocked the bootloader day one before playing with the phone your phone still remains stock. Just the bootloader is unlocked, you'll virtually feel no difference. Except the fact that you have to relock for warranty purposes later but you'll wipe everything so that is always good because you don't want to exchange a phone with all of your passwords.
@andythefan: Yes there is a huge battery difference. Visit the Franco Kernel thread in GSM forums for people's images of battery history.
Flash the James Bond kernel so your gpu will be upped to 384mhz. It is in the development section.

Other kernels also have this feature. A lot of them do.
@stevessvt: In the myriad different combo's I've flashed (ARHD, Franco kernel, APex Kernel, bigxie ROM, AOKP rom, stock kernel, OC/No OC, Unvervolting, and 1 other kernel I can't even remember) I've yet to encounter a single random reboot, FC, or battery pull. I've also flashed countless different mods and basebands, etc.
It's all about doing your homework and really reading through threads before flashing and making sure different stuff is compatible and doing nandroids.
I can honestly say running a non-stock rom/kernel makes a noticeable difference in response and performance in daily use. Its really all the Kernel IMO, ROM's just give you features. I've however never noticed anything from OCing.
@andyfan: what build are you on? 4.0.2 has the hands down best battery life, and 4.0.3 with the Franco Kernel is nearly as good as 4.0.2 was (4.0.2 for me meant ~3% drain in 8 hours)

For now any phone usage will give you terrible battery life due to the high power consumption of the screen especially if when it displays white onscreen content. Average CPU usage is very low unless you're running benchmarks consistently. Therefore UV tweaks have low impact on usage battery life.
With that said if your battery is irregularly draining while idle something may be active in the background.
Franco has made many tweaks to his kernel to reduce idle power consumption. He's gotten it down to about less than 1% drain per hour which can give you over 2 days of idle battery life. Just for ****s and giggles I have achieved that with less than 30 minutes of screen time with LTE enabled.
Franco's kernel is the best I've used in terms of overall battery life but none of the OC/UV kernels have significantly increased my usage battery life.

been looking through a lot of kernels and Roms, anyone have any particular ones they prefer and why? bit of help on mix and match.

Stock, or stock voltage and overclocked.
The kernel handles voltages better than manual users do. The rest of the stuff is mostly fluff.
I'm running codename rom at the moment, overclocked to 1.3 ondemand, changed nothing else, didn't go near voltage settings, but mostly just run it stock

So undervolting and hotplug aren't really beneficial for improving battery life?

I have no experience overclocking a mobile device, so I have no knowledge about what is standard/good/bad/safe/unsafe. Basically I want to overclock my Gnex but I don't want to shorten its lifespan.

I've personally never found a reason to overclock this phone at all, and that's usually the best for lifetime preservation.
As far as I know recommended maximum speed of CPU is 1,5ghz, so theoretically it is safe to overclock it to this amount. But I don't know if the build of GN for example do not make the CPU heat more what can cause less life time in such speed.

A- Best not to get one. Take the bus...
I'm running francos latest kernel. I just picked the highest OC on the list (1344mhz). I think the non-stable goes higher.

Non stable goes to 1500mhz.
About the "to overclock or not to overclock" discussion, i'm leaning towards not needed YET. The phone still packs a punch when it comes to gaming and such IMO.
OP says he is noob with these things aswell, so it might be wise to wait a little and get some android experience before jumping on the OC train.
That beeing said. Every cpu is different so one cpu can be clocked to 1500mhz while a different one will fail when beeing clocked to 1300. You just have to try different clock speeds and check if it is stable or not. The cpu have built in throtteling when temperature limits are reached.

I've noticed that my S3 gets hot quite often and am considering to undervolt my Galaxy s3.
Does undervolting interfere with the performance of the S3? I am the type of user who HATES when there are lags when you scroll through pages, homescreen, and app drawer.
Undervolting is just lowering how much voltage a given frequency uses. It doesnt effect tye performance. The only thing you need to be careful of is instability. Not all chips can undervolt the same. If you undervolt too much for your chip you will get freezes and reboots.

That is exactly right. I have two S3 phones on the FAUX Kernel .10u Version and one can under volt to 800 for min frequency and the other will not boot with these settings. Through trial and error both are stable but voltages are different.

Thanks for the reply. Could you tell me what Kernel / Governor settings and how much i should undervolt to get a stable setting?
It would be great if the performance was still there while saving battery.

I use this kernal : http://forum.xda-developers.com/showthread.php?t=1756776
Things to know about the kernal:
-If you are using a stock based rom use the sammy version.
-You need to reflash the kernal after any rom flash or you lose wifi/bluetooth
The kernal is already undervolted a little. If you want more you need to do some trial and error to find what works for your chip.

Thank you so much. And which app would i use to change the clockspeed and governor settings?
So that kernel will work with stock Bell rom? If i dont like the kernel, can I just reload my previous nandroid image to remove it?
I am running CM10 M2 on my Samsung Galaxy S3 I747
Now my question is which kernel do i use because i would like to OC my phone but it has to have some speed and keeps some battery life.
I don't want to have a lot of speed with hardly to no battery life, i need a little speed plus good battery life if possible.
So if anyone has any suggestions please post

You can try all that work with CM10. It's a preference thing. I'm using ktoonsez. You can OC and UC.

Im not saying there aren't any others as i have only used ktoonez's kernel, http://forum.xda-developers.com/showthread.php?t=1756776 simply because there is, IMHO, no need to. He has versions for each of the available android versions for the i747...obviously you would want to use the AOSP JB based kernel under CM10. Packaged along with the kernel is ktweaker which is an app that gives you control over the clock speeds, under volting, governors, schedulers, plus a bunch of other options. If you overclock your processor you are going to drain the battery faster, you can compensate for this by under volting the frequencies however pushing the CPU too hard can shorten the life expectancy and under volting too far will cause severe system instability. Im not sure how much experience you have with OC/UV'ing but its basically trial and error until to find the right balance of speed and stability that is right for you.Just be sure to read and follow his instructions carefully and dont mess with anything in ktweaker you aren't 100% sure what it does, and as always make a backup in your recovery before messing with system files.....happy OC'ing.

There is a thread dedicated to ktweaker settings on the i747 HERE that would be a good place to start and get an idea of what you are doing. There are also several topics that discuss the different governors and schedulers, what the differences are, advantages/disadvantages to each etc. You can also search google for a plethora of information regarding OC/UV'ing, although most of it will pertain to desktop processors and video cards. While the voltages and frequencies will be significantly lower the same principles apply with mobile device chips.
