OC'ing SGS

Hi there,
I actually want to know if it is harmfull to OC your SGS to 1.2GHz. Ofc it's better to run stock but is it of any real harm and how do you OC? I had a quick test with Galaxy Tuner and I must say when I use my phone heavily 1.2GHz is better. So if this is safe and done easily I would like to do this . Thanks in advance!

Well that seems like a small overclock, so if you have setcpu to your minimum with screen off, it should be OK.

Alright and how long can i use my phone when its on 1.2? Also next to that my phone is in a leather case when not being used so cooling will be a bit harder. Some more information from other people plz? I just want a consensus . Thanks for the quick reply.

my SGS motherboard burnt due to OC....
1 day while i was playing dungeon defenders with OC to 1200, with charger ON. suddenly the phone off it by itsself..
sent to service center, they said motherboard burnt!!!!
lucky they replace the board for me which still under warranty.
so high chance i think is the OC that cause overheat n burnt it.

No one can say for sure what would happen when you push a chip beyond its design parameters. Not all chips are made equal. Usually the standard speed rating is what all chips passing QC should be able to operate at. However some chips may be able to operate at higher speeds without ill effects while others may fail catastrophically even with a slight increase in frequency. So its anyones guess...
Frankly I dont see the need to overclock right now. What ROM are you using ? Flashing to a newer / better ROM can give you a bigger improvement than what 200Mhz can give you on a laggy unoptimized ROM, so why risk it ?? .

The fact you where charging, and playing a game probably had more to do with it than your overclocking.

+1, charging and gaming at the same time is never a good I idea. They both heat up the phone greatly

Hmm I'm running docs mod v9.9.5 XD with speedmod kernel and twlweaks enabled. So it pretty fast already however with the oc there is just less loading time. But you are saying that its useless?

If you can oc, that means you root right! either that or droidclock/setcpu correct?

it depends. i personally use tegrak overclock and for battery saving, i use overclockwidget. my sgs has been going for 2 days in a row with battery life only at 48% even with moderate usage(making smses, playuing games occasionally, etc.)

Hmm alright, these apps seems legit. What are your settings with these apps? Or should I use setcpu?

If the phone reaches a certain temperature, the phone stops charging, so i dont think playing a game and charging at same time is the culprit.
Granted that the phone would heat up A LOT quicker than usual, but being so hot, the phone wouldnt of been charging even with the charger connected.
there is now way of knowing whether overclocking is dangerous. Personally i think it is, you have to modify the kernel, modify system settings, modify battery voltage.
None of this is recommended, but we do it at our own risk...
Its as dangerous as running a custom ROM or LagFix. some devices are fine, some brick and burn to a crisp.
So choice is yours

Hmm i guess ill be sticking to 1ghz then... thx for the replies!

i do the same for my x10 n the phone running just fine.
in fact, before i sent my i9000 to samsung for warranty claim, i pass the phone to a local shop, the tech told me the OC cause the board overheat, then burnt it....

Actually tegrak oc works fine. ocing at 1.3 will crash first time but not crash anymore after the first time. ocwidget is not really useful for ocing but just to same battery life. when not really using my phone i will set it at 100mhz-400mhz. you can play angry birds on stock rom with little lag.

So you're saying i can oc.... but im running setcpu. I can OC with setcpu right? That brings another question when my screen is off what setting should i use for setcpu? In other words what is the minimum frequency?
Sent from my GT-I9000 using Tapatalk

100MHz is fine for the minimum frequency (for me at least) - this may vary between phones, give it a try.
On the subject of over-clocking though, you should take a step back and ask yourself "How much do I really need those few milliseconds less to load up Angry Birds".
I would suggest that Samsung did more testing than anyone on this forum.
All that said though though I take my phone up to 1.2 sometimes for ****s and giggles & to shut up smug iPhone fanboys

No. Don't set set setcpu to anything below 400mhz because when the galaxy slips into idle mode it cn sometimes be difficult to wake up
. I'd imagine such a low clockspeed would encourage such behaviour. I set my minimum at 400mhz and max at 800mhz. Spot on.

[INFO] Custom Kernels & Overclocking - FuguMod Ultra Pre Release

After reading through the Thread for the Pre Release of FuguMod Ultra in the development section of this forum I thought I would post some info up for people who are wondering why it doesn't work with their phone, and just some general info on overclocking.
- First off, not all phones will be able to run at 1366MHz. Every CPU made has a range of freuqencies it will work at, and it is different for every single one. So some may be able to handle 1366MHz and above, others may max out at 900MHz. If you are getting black screens, freezes, or random behaviour, then your CPU doesn't like the frequency you have it at, try a lower frequency.
- Always keep an eye on the temp of the CPU when testing overclocking, if the CPU gets too hot, and fail safes don't work, there is a chance you could fry your CPU.
- With the FuguMod Ultra kernel, you must also be aware that gpu bus frequencies have been changed, so if your phone is not happy with that it will black screen. (as bus speeds are like cpu speeds, every different device can handle different clock speeds)
- plls values have been changed, and these may cause problems on your phone.
So if you want to have a go at overclocking your phone, back it up, and then give it a go. Select a frequency, and test with something pretty cpu intensive (3d game, multiple quadrant passes) and see if there are any bugs/overheating during a 15min time period. If you notice any problems/too much heat, try a lower frequency, and try again. And if for some reason your phone doesn't like the kernel, you can reflash with your previous kernel or a new ROM as you have already backed up your data.
If you have any other questions about overclocking, feel free to post here and I will try my best to answer them.

How can you check the CPU temperature? I thought it was only battery temperature.

The battery temp is a good representation of how hot the processor is getting as it is right next to the battery (only a thin sheet of metal seperating it) If the battery rises in temperature by a few degrees, then you can summize that the cpu is probably getting a few degrees hotter than that. I really wouldn't recommend letting the battery get above 55degrees (celcius) as this means the CPU may be getting up close to 65degrees (celcius) which is a very bad thing.

Good post.
Note that if you want to make some stress-tests, you have to put "PERFORMANCE" governor and set the max freq you want to test.

How have you got your phone set up? i.e. what ROM are you using etc.

I am using stock jpq with app2sd, swap, zipalign, ramhack and stuff. Setcpu is installed with default min/max freakquency, No profiles in use and undervolt a bit.

Ok,
This may be an issue caused by XXJPQ, as it is a new release there may be some sort of conflict. Have you tried asking if anyone else has this issue in this thread? http://forum.xda-developers.com/showthread.php?t=1132697
I haven't played around with JPQ yet so don't know what the bugs are yet.
Also, are you running a stock kernel? Have you confirmed that the phone has been rooted properly as well?

It's definitely a bug in Kernel. I tried three different roms and i wasn't able to check time in state in any of them (I am talking about fugumod ultra prerelease kernel here).
With previous versions of fugumad kernel everything is fine. So definatly a bug in kernel.

Ok cool, I'll report the bug to the developer so that he can have a look into it. Thanks for testing and proving to the kernel.

Little bit of info some might find helpful. After some recent testing, I have found that some people might experience a black screen freeze when phone is in standby for a while with 83MHz min setting and on demand governor. I am not sure of the exact reason for this, whether it is a bug, or that the processor just doesn't like going that low for extended periods of time. If you experience this type of error, just hard reset the phone then open setcpu after phone has loaded and change the "standby" profile minimum to at least the next step up on the slider. Personally I use 223 setting as it provides a smoother lock screen animation, and no significant difference in battery drain.

Trinity kernel OTG crash/freese bug

Hi
Sorry cant post in the development thread since i just joined.
Using TS1700-GPUOC-4.1.2-mr1-fr-ALPHA12 with CM10 causes Nexus 7 to Freeze/crash and reboot when you remove a USB pen drive or 2.5 harddrive that is connected with a OTG cable. It happens if you do a dismount from settings/storage or just pull the cable OTG cable out.
Otherwise its a very good kernel for Nexus 7.

Finally! I could Kiss you!! I wont don't worry.... at least however a manly high five will do. I am having this issue since using the Trinity Kernel and like an idiot never once though it was the Kernel. Strange how the units will still turn off even if you just plug and unplug in the OTG cable with nothing plugged into the cable itself. So we think it is the Kernel then?

Yes, 100% certain its kernel related.
When you run CM10 updater from inside CM10 and a new nightly build gets installed it removes Trinity kernel and install the default CM10 kernel and that makes the problem go away.
After you flash Trinity kernel back you get the freeze and crash/reboot issue again.
If you use this Kernel, please contact morfic. check his site below for email and other contact information.

Thank you Cazrack. I will email him now, I can imagine he will be inundated with emails
Another two quick questions "sorry" with Trinity, do you use setcpu to overclock or do you find the kernel gives you all the speed you need? secondly have you had the issue of the unit turning off on an overnight charge? I do not do this normally but I fell asleep with it plugged in and found in the morning it was turned off, when I turned it on it was at 100% so thought is might have turned off as a safety feature but just wondering if you experienced this or heard of it happening?
Thank you again for you help.

The same thing happens to me with the Trinity kernel but it also happens with LeanKernel for 4.2. It did not happen with LeanKernel for 4.1.2, so I don't think it is just a kernel only issue. It doesn't happen on the stock kernel, M-Kernel+, or Franco r30.

I keep the stock clock speed 1.3 ghz but I use setcpu to set certain programs to scale to 1.7 ghz.
For example webbrowsers benefit from 1.7 ghz in faster loading and smoothness.
overclocking for games i prefer to run cpu stock and have my gpu overclocked to 600 mhz.
stock gpu is 416 or 418 mhz.
cant overc to much during long gaming sessions since it get to hot and gpu oc give more than cpu.
when i used franco kernel r25 the power off thing happend to me too.
only 1 night during charging but i flashed a new kernel after that.

Ah I see I have done the same it works very well. However you mentioned overclocking the gpu to 600mhz how is this achieved? its not an option in setcpu, suppose the programe is called setgpu
I think I will stick with the the Trinity as the OTG restart is not that much of a issue really. I am sure derkernel will have an update soon.

yes you can OC the gpu for better gaming fps on some kernels.
for example Trinity kernel and Franco kernel allow this if you use franco.kernel.updater from google play store.
i have tested 700 mhz but but during long gaming sessions with games pushing the gpu hardware like spiderman it just get to hot.
484 and 520 mhz is considerd very safe from the information i gatherd.
600 should work even for longer gaming sessions but the device will be warmer.
650 i will test this but im sceptical about long gaming sessions.
750 some crazy people run this....
at the moment im using cpu gov ondemand in setcpu with value 50 in cpu scaling.
have you tried the elite kernel? 1.8 ghz cpu 650 mhz gpu..

Okay I see it comes full circle, I will give it a bash.
The elite was going to be my next kernel... only reason for using Trinity was, I was advised to do so as a first try. It might be the next step to get rid of the OTG restart and of course the 650 mhz gpu stock oc. Have you tried it or going to try it?

because trinity animation still showing after flash... but nexus isnt booting up.
no problem just boot into recovery and reflash trinity kernel or a cm10 rom.

prehaps reflash elite when you have updated to a 100% cm10 nightly installed.

Fix For Back Of Tablet Getting Hot (Still Overclocked)

I found when running Shadowrun Returns with the ElementalX 1.4 kernel http://forum.xda-developers.com/showthread.php?t=2389022 at 1.944 GHZ the back of the Nexus 7 gets hot. This worried me but I noticed when I installed the kernel was an option to use cool thermal throttling. I tried this and now the tablet does not heat up at all. You need to be rooted though to install the kerne of course not sure if ElementalX 1.4 works with stock though, I'm running the latest CM 10.2 nightly. It doesn't seem to affect the performance of either Shadowrun Returns or Wild Blood, the two games I'm playing at the moment, I still have the GPU overclocked to 487 and the Dalvik etc overclocked at the moderate ElementalX setting. . I think being able to run at 1.944 GHZ on my tablet with the cooler thermal throttling is better then running at stock and I believe that even some running at stock have that issue.
Hope this helps others that have this problem.

That's a good sign as you know the heat is being distributed effectively away from the internals. You don't need to be rooted to flash custom kernel. And setting different governors will have a major impact on your CPU.

You might be right about not needing to root to install a custom kernel though I couldn't find a definitive answer in the Nexus 7 2013 forums. I assumed it was needed from using custom kernels on other devices.
My device gets hot while gaming. When you are doing intense gaming like I am I'm sure pretty much any governor will max out the CPU. I know Intellidemand which I use does for sure.
When overclocking, heat is the enemy and it can damage, crash CPUs and even affect the performance of them. I believe if you are concerned about your Nexus 7 heating up (mine does for a good area between the logo and the camera when not using the ElementalX cool thermal throttling) then my advice is good.
Peace.
P.S. How the heck have you done 675 posts since June 2013?

Kernel is flashed separately from the ROM. Rooting is only for running apps like Trickster Mod to configure to kernel. Otherwise you can have stock 4.3 ROM with any kernel you want. Heating up will obvious affect performance due to thermal throttling but I was not concerned of damage even when the CPU of my 2012 Nexus 7 got to 80 degrees celsius from running overclocked performance stress test under direct sunlight in a case. If your CPU crashes then it's likely not overclocked correctly. Otherwise if it remains stable under artificial stress test, it will handle any game no problem.

I would really appreciate if someone explain me how exactly this function works?
I mean, tablet don't have fan, so how it keeps the cpu cool, and also what this option does to my nexus in order to keep it cooler?

I would not over clock this device. It us more than fast enough for any Android game.
Throttling does just what the word describes. In basic terms your cpu will be slowed down when getting hot and this defeats the purpose of over clocking.
I won't mention the instability that can be caused or the possibility of doing damage.
Just my thoughts.. To each how own and I do have my I7 pc cpu over clocked big time but it has a huge fan.
Sent from my shiny new(bought last Nov), scratch less Nexus 4!

I agreed, throttling and over clock doesn't make sense but this CPU is underclocked and it is designed to go higher like the one on the galaxy s4 and the GPU is meant to go higher but due to battery life Google underclock it

Well , its not under clocked by Google, this is underclocked cheap from the factory , its just a lower bin s600 that has been rebranded as S4 Pro .. If it was regular s600 it wouldn't be underclocked .

When the CPU reaches a certain temperature threshold it begins to cycle down the CPU speed in order to cool down the processor. It makes the CPU start running at lower frequencies to keep it cool.

Exactly, so a quick oc and u got a better processor without worries of damaging the chip

Trickster Mod Thermal Throttling Settings
Hey,
If your CPU is getting hot (especially if it's overclocked and hitting 80 C or near to it) At 1944 the back of my case would get noticeably hot. I still say it isn't good for the CPU. From what I know about overclocking if any CPU gets too hot it can damage the CPU or degrade it over time. I definitely wouldn't want it even getting to 80C before it throttles but I found in Trickster Mod, even the free version, you can set the throttling to custom settings if you are rooted. Custom kernels set their voltages to scale depending on the clock speed which means lower clock speeds, less voltages, less heat. I'd rather keep the temps lower on the CPU then risk damaging the device or degrading it over time. Also you can undervolt the CPU at the kernel different clock speeds so it heats up less. You can run the free AnTuTu Benchmark stability test to see if your clock speed voltages are stable and will not crash your device. I have my CPU overclocked to 1944, thermal throttling down clocks the CPU to 1836 at 73 C, 1620 at 75 C, 1512 at 77 C and 1134 at 80 C. My voltages I lowered and are stable at 1944 - 1087500, 1890 - 1062500, 1836 - 1035000, 1728 - 1025000, 1620 - 1000000, 1512 - 987500. The lower voltages are undervolted as well but not going to list them all here.
Peace,

P.S. When it was posted in this thread you can install custom kernels without rooting it is correct, I recall reading that at one point. Like it was said to use Trickster Mod, change governors or custom throttling settings you need to be rooted.

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.

Hello,
What do you mean by ex kernel?

He means the app, EX kernel manager.

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..
