Hello, running Nocturnal's rom, and sk8ters kernel on my LGOG. When I do anything remotely taxing on the phone, light gaming, benchmarks, etc, my phone starts to warm up, and then it will kick me out of what ever I am doing, and when I go to check the CPU settings, its down to 1134. After awhile it will kick itself back up to full speed. I believe this is a temp thing that is kicking the CPU down, my question is anybody elses doing this? It only takes like five minutes of hard use for it to kick itself down.
Do you have the ecomode box checked in the Quad core control setting? Not sure if that's the issue, but I would check that.

Check your battery, it may be the cause for this problem. The battery is what heats up the phone the most, if it is leaking, or damaged in any way then it can cause this
Also try cleaning any vents on your phone, they may be clogged, not allowing dissipation of heat
Alternatively, check which kernel and cpu governor you are using, if it is terribly inefficient it can be causing the cpu to stay at high frequencies, which can cause it to increase its TDP footprint

Phone is brand new, so there really are no obstructions. I am running on demand, with noop I/0. Is there a copy of the stock kernel somewhere I can try to see if that is the problem? Also, econo mode is off.

Try switching your governor setting to something less powerful and more conservative, on demand often causes the device to constantly remain at max cpu clock speed, draining power and heating the chip

Are you aiming for battery life or performance? If battery life is your goal, try what's in my signature. If you're going for performance, the simplest approach is to set your screen-on profile to 1420 (or performance governor) and nothing else, and your screen off profile to 800.

Oh okay, thanks, but what will happen if I put 1420 high and 100 min? Cause I want my Kernal to be free and not suppressed at the standard the phone puts, will that "free" it and will it kill battery faster? I hope you get what I mean, lol

Shouldn't be a problem setting 1420/100. The biggest problem I've found with overclocking is the "Sleep of Death", which occurs when you don't have the proper settings for screen-off mode. At 1200 OC, it's recommended to set your minimum frequency to 400 to avoid Sleep of Death. I believe at 1420, 800 is a safe bet to avoid Sleep of Death.

All depends on how you use your phone. When your phone is on and you're gaming which will ramp your speed up to the maximum, then yeah. You're gonna burn more battery. I'm more battery conscious myself, and find my UI and experience smooth as silk at 1.2 with Bali-X while still getting massive battery savings with the phone spending most of it's time under 800mhz when I'm doing less intensive tasks like SMS.
At this point, your best bet is to simply test it out. Your mileage will vary depending on the ROM and kernel version you use.

Does anyone underclock? I only do it in certain situations. Do you see it as beneficial? Why or why not?
Sent from my Galaxy S2
EDIT: My settings are attached as a screenshot. My device is underclocked 50% of the time.
In my opinion and from personal use, I don't find underclocking to really be beneficial. I never really saw any better battery life. On the same note, I never really found overclocking and undervolting to be extremely beneficial either. It's like the gains aren't worth the time to tweak everything.
Undervolting, yes. Limiting clock speeds, and setting governer to conservative, yes. I say 1ghz is the best spot without losing much performance, and I get 2 days of battery life (sometimes) compared to the one day before... Stock kernel, you aren't going to see much of a difference because you can't undervolt...
I keep my phone at 800max 200min on conservative with a 85% up and 20% down threshold. I don't even see the phone slow down at 800 plus it saves some battery!
I force underclock when I'm in a situation where I KNOW the clock should never ramp up (Screen-off I set to 500) as a "safety measure" to prevent surprises.
I also may force underclock to 800 when running Navigation once my vehicle dock comes in - since we can't crank our charge current up.

My screen off is set to this also (200-500, conservative). You can use Tasker to change frequencies for specific apps automatically.
Has it ever been heard of that someone killed their gs2 from using 1600mhz in daily use?
My gs2 likes to have 1475 as a minimum voltage for 1600.

Ever rev an engine into the red? Did the engine blow up on the spot? unlikely. However if you constantly KEEP the engine in the red it will eventually break down.
Same thing for OC phones. The processor in the SGS was designed for somewhere around the 1ghz mark. Pushing it 110% likely wont kill it, they build allowances and tolerances into these things to help them last longer. Push that processor to 150% and you are risking serious damage.
Monitor the heat, if you notice its getting HOT then you should really pull the battery and let it sit for a while. Nobody here can say its safe to OC your phone like that, its a calculated risk you obviously didnt spend a lot of thought into.
TLDR: Just because you CAN doesn't mean you SHOULD.
Actually its my thought the reason I haven't been using it on 1.6 yet, and why I'm asking. Iv been ocing my pcs since the late 90s
Now the reason I'm asking here is because the cortex a9 was designed for up to 2gHz operation, but this phones design may or may not provide adequate cooling, that's why I'm asking if other people have any negative experiences with this.
Were not actually over reving the chip its more of a environment issue with cooling/ventilation.

You do have to have in mind that PCs are much safer to OC, so we shouldn't really compare brtween them.
Regarding the Phone OC, I haven't OC'd mine and probably never will because I have all the horsepower I need, but I think the "safest" OC is between 1.3 and 1.4GHz, since that's a range that all CPUs are designed to overtake (max 200MHz range ).
mine's been oc'ed, uv'ed pretty much within the week I bought the phone in june.
I've got it set to clock between 500-1600Mhz on demand and I've not had a problem yet. Mind you, not many tasks you do on the phone will actually require 1600Mhz and my phone's CPU clocks mostly between 500-800Mhz.
Playing some games or doing quick video conversion will push to 1600Mhz but I rarely play games on my phone and video conversion is short process - burst of 90 seconds to 120 seconds at most. So I think you should be alright so long as you don't leave your phone CPU at 1600Mhz at all times.
Like you said, it is the cooling and ventilation system on the phone, which you can't modify.. Unlike PCs, where you can install bigger fans or water cooling systems. So if the phone isn't constantly cooking itself inside, should be alright.
You should already know that OCing anything is dangerous since you overclock PCs,so I'll skip that part.
Well,if it's dangerous for the phone...It depends.Yes,the processor will die sooner.Yes,you risk frying your device.No,you don't have to push it to the limit(don't push it more that 1450μV,that's the general advice for 45nm chips).However,my thoughts are:
-I won't still have the device when it's time for its CPU to get fried,so I don't actually care.
-Something else,probably the Amoled screen,will make the phone useless by breaking sooner than the CPU will.
-This winter here is really cold(for our standards anyway),so heating has been taken care of.During hotter weather,I kept multiple temperature profiles in SetCPU,so that frequencies get lower as temperatures get higher.
In the end,what matters most to me is to have the experience I want.And with OCing my phone I get it.I'm happy with it,that's all I wanted.So,it's personal preference.Some feel they don't need it,others feel they do.Decide for yourself,that's the best advice.
PS:In case you are using Siyah kernel or CF-Root with Tegrak overclock,try lowering your clock by small steps(8Mhz is the smallest step) for a sane voltage,say 1400μV.Sometimes small increments make big differences.
Thanks for the advice guys. Appreciated.

Don´t oc sgs2.
I got my mobo fried without oc.
Service center replaced everything else but housing and screen.
I used it 2-3 hours in a row, installed programs and put it in charger.
In the morning, it was completely dead.
Overheated because of the use and charging.
So think about twice before using oc 24/7.

I bet you didn't know there are faulty products out there that show their faults during intensive usage,eh?Mine's running at 1.6GHz(give or take a few MHz ) for months.I've played games while charging countless times.And my phone is still here,intact,so that I can write this here.

Of course my sgs mobo could have been faulty.
When the mobo fried it was hot, i mean hot.
I didn´t look temperatures.
It didn´t wake up even using jig.
I sended it to service.
If they had succesfully woke it up, they wouldn´t fix it on warranty (rooted).
Normally oc would be fine because it´s using powersave and underclock it.
But if you play like 2 hours on 1,6Ghz it can get too hot (over 60c on cpu).
I can´t recommend that kind of temperature.
And nobody here knows what kind of vrm´s phone has.
Also cooling plates are not designed for massive oc/voltage.
Of course temperature depends on voltage more than the clock speeds.
It´s up to user if he want to use it that kind of voltages/speeds.
I would´t use it 1600Mhz/24/7.
Generally i know what i´m talking about (using water on pc...)
Just look for temperatures and don´t give too much voltage (as low as possible).
Of course you don´t know safe voltage limits, but try and look what other have been using.
Don´t oc much if you don´t know what are you doing.
@tolis626 Hi, I have oc'd to 1.4ghz for the last few weeks, and I have under volted it to 12.75mV, the same as you, have you had any problems at that voltage? Also, is your 1200mhz voltage stable as it seems very low, to say that it was, at stock, 13mV. Furthermore, have you ever tried to under volt 1600mhz please?

Well,since 1400MHz and 1600MHz aren't stock clocks,you don't actually undervolt them.You rather choose a voltage for them as there isn't a standard one.
My phone is stable with the voltages in my sig(I've only changed 200Mhz and 500MHz voltages a little but too bored to update my sig ) for months,so yeah,I'd say I don't have any problems.This doesn't mean that no one will.Your phone might need 1325μV or 1225μV for 1400MHz.Every phone's CPU is unique in its own way.
@tolis626 Thanks very much, one more stupid question please, will under volting from stock Samsung voltages, even if it's stable, decrease performance compared to stock voltages on an average exynos processor please, aslo will undervolting from original kernel clock speed increase the processors life span? I have researching this and came up with nothing.
Will it break your phone? Not directly. It will shorten the lifetime.
Besides that the heat can indirectly kill your device.
I'm just curious:
Why overclocking the device? I have mine underclocked to 1 GHz max. It still has enough power to handle everything.

No,undervolting will in fact prolong your processor's lifetime,albeit negligibly,because with less voltage less heat is generated.It's plain physics.
Overclocking on the other hand will reduce your CPU's lifetime.The damage(mostly electromigration) is dependent on the CPU and how much you overclock.Quite frankly again,you won't still have the phone when enough damage is done for it to break.If the slightly lower battery life doesn't bother you that much,I say go for it.

Thank you very much for all your help I tried undervolting 1200mhz more, I got to 1075mv and it was rock stable, I don't think I am going to try anything lower than that. Just for info, I'm on SiyahKernel v2.6.2 Thanks again
CPUs care a lot about voltage and don't give a rip about MHz except for the minor heat increase. The chip in my phone is a bad clocker though. If I could get 1400mhz to work at close to the stock 1200mhz voltage I would do it in a heartbeat. Sadly mine requires a healthy bump so I abstain. At least until I can afford to replace it
Number one rule of overclocking, don't push the voltage if you can't afford to replace it
I discussed the topic of overclocking processors with a friend of mine who design cellphone CPUs. He told me that over the lifetime of a CPU, the insulating oxide layers break down. This process is considerably faster at 40% extra power and frequency. So don't expect it to last as long as a normally clocked CPU. So the question is how long it would normally last.
I have my SGP5 overclocked to 1.5ghz at the moment via Tegrak. Everything is running smoothly but the spot on the back where the CPU is gets warm to the touch. Not hot or anything, but obviously warm.
Before I had it overclocked to 1.45ghz and it stayed a lot cooler, but to get to 1.5 I had to bump the core voltage to 1.35v. I also have the up-threshold set to 35% so it spends a good amount of time at max speed.
Since these things don't have CPU temp monitoring, how do you tell when it's too hot? My battery temp never goes much over 80*F, so that doesn't seem like a good indicator of anything.
Sitting here playing music with Mufin my IR temp gun reads a max of 100*F on the back of the case over the CPU. Battery temp is reading 77*. Is that too warm? How much of a temp differential can there be between the outside of the case and the CPU itself?
I'm no noob to overclocking PCs, but this is my first Android device so I don't really know it's limits as clearly.
Any help would be mucho appreciated!
DISCLAIMER - anything within this thread has the potential to do permanent damage.. I haven't had any issues yet but will not be held responsible for any damage!
So I just pulled the back cover off it. Running the same program for 10-15mins the CPU never exceeded 82.5*F which is well within safe limits imo.
I guess that goes to show how poor the cooling is in one of these things with the back cover on. I'm going to keep running 1.5ghz and report any issues. The difference in smoothness between 1.4 and 1.5ghz is pretty dramatic.. web browsing is very very smooth now. I probably won't be going any higher than 1.5, but for now it seems safe.

Is there any major danger at this clock speed with On-Demand on? I mean, it'll only use 1.5GHz if it needs it right?

Ondemand from my understanding, scales processor speed using the values in the up/down (I believe System Tuner refers to down as "powersave bias") threshold. From my experience it's the best governor to use as far as customizing it easily and getting it to respond well.
Whatever you set the up-threshold to, when CPU load exceeds that value it bumps the speed up to the next "level" and ending in full speed. Then when CPU load falls below the down-threshold, it scales it back down to the next lowest level, so on and so-forth. You can also adjust the sampling rate too - lower frequency means it checks the CPU load more frequently and essentially makes the governor more responsive.
When I set mine to 35%, almost any program aside from stuff sitting almost completely idle will trip the CPU to hit 1.5ghz. This makes everything real responsive and may use more battery.. but I prefer having a more responsive device. You can also adjust the up-threshold to a higher number to try to lower temps and extend battery life. You can really play around with it to suit your needs, there's not really anything to screw up there.
There shouldn't be any danger using it with the ondemand.. but since I haven't tested this for more than a few days right now just keep an eye on temps (especially while playing games) and watch out for any "stuttering" out of the blue. Mine gets warm but nothing excessive. You'll be able to feel it on the back between the speakers.
I have to say though, even running such a high clock speed I'm not really seeing any negative effect on battery life so far.
Lemme know how yours goes!
How can it not have any risks? When the heat is too much somethig will explode wouldn't it?
No just kidding, but seriously. There is a risk of overheating a hardware and 'destroying' it, there should be!

Well of course there's always some risk in overclocking! Especially when you don't know what you're doing.
As far as using one governor or another though.. when it comes down to it there shouldn't be a huge difference.

Hi, I've got an annoying problem...
As far as i know the first thermal threshold for kicking down the CPU freq to 800MHz is set to somewhere around 80oC in SGS3. But in my case it kicks in after achieving just 51-54oC which makes some games unplayable after 5 mins
I've read somewhere that the battery temperature (45oC or so) is also considered when throttling down the CPU frequency, but my battery hits just 41oC when it happens...
Could it be a faulty temperature sensor(s) or just faulty almost 2 years old battery? I have no more clues, could anybody help?
Thanks a lot!

I've read somewhere that the battery temperature (45oC or so) is also considered when throttling down the CPU frequency, but my battery hits just 41oC when it happens...
Could it be a faulty temperature sensor(s) or just faulty almost 2 years old battery? I have no more clues, could anybody help?
Thanks a lot!

That's tricky... Afaik you CAN change some system files to avoid throttling but I don't believe that that would be healthy... Your temperature sensors could also be faulty... I don't know

yeah, but is it possible that it's throttling down on such normal temperatures? Or maybe there's another safety mechanism involved (dunno, maybe GPU temp sensor)? But my GPU runs on stock freqs and voltage...also it doesn,t matter if i'm undervolted on CPU or not, still the same

I don't actually know... I've never faced throttling problems so i don't know what else can cause this.. Perhaps there is something else involved...

SOLVED
After a really deep search I found out that Sammy based roms have a CPU throttle after battery reaches 41oC...now to change it
