Galaxy S3 overclocking

Hello guys. I just want to take information that there are many tweaks to overclock galaxy s3 to max 1.8 ghz. If we set to maximum overclocking then is there any risk for damage hardware? Because 2 months before i had nokia n8 & i set this device to overclock & it damaged all board,now its totally destroyed. According to my point of view,sometime i think that nokia n8 has only 680 ghz & due to overclock it run on higher clock speed & so that due to low processor it could not manage or handle the higher clock speed & it ran on heavy clock speed continuesly then overload of processor it got damaged. It is my fear for s3. And i think for s3 that it has higher processor with 1.4 ghz,if i set it to 1.8 ghz then there is no risk bcoz of there are cpu governor. With this,the s3 does not run continues on 1.8 ghz higher speed, governor takes control over the cpu to run on higher clock speed according to their high usage like 200 ghz, 500ghz, 800 ghz, 1.4ghz & so on. So i think i can overclock my galaxy s3 with kernel but I'm still confused & I'm not expert. So plz suggest me to do overclock without any damage fear. Thanx a lot.

If i don't but you know then u can tell me about any risk.

NOTHING is without risk, but a good place to start is just to install the latest Siyah S3 Kernel and run it it at 1.6ghz for the CPU and default settings for the GPU. I tried running my CPU at 1.7 and 1.8 and the it wasn't 100% stable and the temps were to high for my liking. Be moderate in your settings and you shouln't encounter any issues.
http://www.gokhanmoral.com/ latest version is 1.7rc1
That will give you a good performance bump with the minimum of risk (in my opinion).
Other than that installing a bloatware free ROM will also give a nice bump. I personally run Omega V29 with the above 1.6 overclock settings and it lightning fast. :good:

There is always a risk involved in overclocking.
1.8ghz isn't stable for most people but 1.7 is quite stable.
How well your device handles overclocking depends on the quality of the chip you got.
This is down to the manufacturing process, you may get a good chip from the middle of the wafer or a not so good one from nearer the edge.
if you want to reduce heat them you should undervolt the CPU, less current means less heat.
Obviously it isn't good for the hardware in the long run but that's what you gotta take into account when you overclock, I've overclocked every phone I've ever had and haven't had any problems but YMMV.

could u plz tell me that what is the process of undervolt if i undervolt the cpu then it is related to only heat or performence also?

If you use siyah kernel then in the stweaks app that comes with it you can choose how much you want to undervolt.
I suggest starting with -25mv or -50mv and check stability.
I use -100mv without problems but like in said earlier YMMV.
It doesn't give a performance boost per se, but less heat in the chip will mean that it doesn't hit the temperature throttle threshold as easily and that means more performance.
The CPU will begin to throttle (limit clock speed) at around 75c until the temp drops and the CPU is allowed to run at max clock speed again.
Usually you will only hit the temp throttle threshold under very heavy loads, for example repeated benchmarks.

1.7ghz should be alright for a 32nm chip like the exynos 4412 on our s3. HTC has had their One S (with a 45 nm chip) clocked at 1.7 ghz. The lower the nanoneter, the more ambitious you can be with clock speeds. Try 1.6 or 1.7 ghz with default voltage settings and see how that goes

You are using -100 undervolt, that mean its high current & mean if i select 25 to 50 then its less current than 100??? & is there any battery improvement if i select less current mean less heat.?

I am using -100mv, as in minus 100mv, 100mv less than stock.
Less current is less heat and *maybe* battery savings.
-100mv is less current than -50mv.

Antutu and Quadrant, all are just bull****. Just to see their manipulated scores, overclocking does not make any sense.
At ground level, applications do not run anything faster as overclocking alone does not work here. Even if you get milli milli milli second improvement which is just nothing against damage of CPU.
Got it?? now start using your phone as it should be and made for.

Before overclocking you should ask yourself Why you want to overclock. If it's because the phone have some lags there is other(safer) way to solve this problem. Honestly I overclock mine for a while (just because I'm a tester) but the S3 is fast enough for everything. You should see my S3. The app drawer appears (almost) instantaneously. Any games play smoothly etc...
On this phone overclocking is possible but useless. If you want to learn how to overclock just to learn how, search in the stickies for the overclocking guide.

I have tried overclocking and undervolting for the last week now and I can say that overclocking has not made any visible difference to my S3. Overclocking seems to be a nice option to have, but the S3 does not need it. Undervolting on the other hand reduces lag considerably when playing games for long periods. Usually my S3 started to get laggy after about 1 hour of Asphalt, but now it does not get laggy at all. I have undervolted by (-)125.
Hope that helps.

When I play pokemon black 2 on nds4droid without overclocking it gives me 20 to 30 fps and when I overclock it to 1.7 GHz i get 28 to 35 fps

Firstly you need a kernel supporting overclocking... Secondly its fine if u wanna play around with your device... Lastly I would suggest u to overclock it to 1704 MHz max (avoiding any boot loops )....
I would recommend Siyah 1.9.1 (as your Kernel) and "Noop" as your I/O Scheduler... In case ure using Siyah as your Kernel, try using "Lulzactiveq" as your governer...
Furthermore u can tweak the governer if u want more juice out of it....
Try it.....

I have tried overclocking to1600, and although Quadrant stats are higher, I did not notice any difference in normal usage. I am a general usage text and phone calls and email user. Minimal game playing. I stick to 1400 now and everything seems just the same!!
At the moment I am running Sotmax rom and boeffla kernel.

Overclocking

Hey guys, just wondering what the maximum frequency our Snapdragon S4 Pro CPU's can handle??
Thanks peoples lol
Sent from my Nexus 4 using xda premium

What's the point in over clocking on the n4? Are the improvements actually noticeable for anything besides bench testing? Meaning is it noticeable when doing day to day activities? The reason i ask is because my phone has handled everything I've thrown at it with no issues so far.....just curious I guess

If you use trinity kernel, you will be able to oC to 1.8Ghz. It used to be able to OCable to 1.9 but I think there were substantial issues with that level. Overclocking will ruin the CPU life span. Overclocking is more suitable for computers. This phone is really quick and smooth out of box. Overclocking it is redundant.

Good question but, to answer the OP 1.94GHz is the max. More may be possible however, no one is foolish enough to risk 2Ghz+.

Okay let's set this straight:
More Overclock --> Faster speed --> Lower stability
Increasing Voltage --> More stability --> Higher temperature --> Dangerous
To be able to achieve a higher clock speed, you need to have a higher CPU voltage in order for it to be stable. If you don't increase the voltage, the CPU will churn out corrupted data, and in the worse case files will become corrupted as they are written into memory. But it WON'T damage your hardware. However, because you are increasing the voltage, you get more heat, which can damage your hardware. So it's actually the overvolting bit that is dangerous, not the overclocking.
As for maximum clockspeed, you might find this article interesting:
"Theoretically, your upper limit would be due to the propagation delay in sending electrons from one point to another, which would be the speed of electricity. Electricity travels close to the speed of light and light travels a foot in a femtosecond (10E-15 s) so the top speed is somewhere in the 10E22-10E23 Hz range. However, this limit will never be reached as this assumes no capacitance and no resistance in the wire."
- Source: Mu_Engineer (http://www.tomshardware.com/forum/250325-28-limit-clock-speed) -
1 GHz is 10E9 Hz, which is nowhere close to 10E22. Even taking into account the resistance of the circuitry, 10E9 is still very low. So 1.94 GHz is simply the maximum STABLE clockspeed you can normally achieve on a Nexus 4. In addition, developers might impose arbitary limitations on how much you can overclock your CPU, but that's just a software limitation.
In conclusion, the answer will depend on which of the following questions you actually want answered:
1) What is the highest stable clockspeed the XDA community has managed to achieve without external aid (i.e. liquid N2)?
2) What is the highest clockspeed allowed by currently available kernels?
3) What is the physical clockspeed limit of the Snapdragon S4 Pro assuming external aids are allowed? (E.g. connecting your CPU to a higher voltage source directly while keeping it cooled with liquid helium. Even then it would probably only lasts for a few seconds.)

Why don`t you overclock it yourself and post your findings here, overclocking the N4 is useless imo and only nice for those kicking on benchmarks.

I won't because at the moment I fail to see any reason why anyone would need to OC their Nexus 4. So yes I am agreeing with you.
However, OP asked for the highest clockspeed, not for opinions on whether OC is useful. Saying that OC is useless in response to his question is similar to telling someone that they should eat at Burger King instead when they ask you for directions to MacDonald's. It doesn't make your statement any less true, but you are not answering his question.

With some Kernel like Faux you can OC up 1.94Ghz (Turbo Boost Ultimate) but not all CPU hold this frequency.
I think 1.83Ghz (Turbo Boost Mainline) is more reasonable.
Both Kernel just mentioned also OC GPU to 487Mhz.
Personally i don't Think we need to OC our Nexus 4, I've never seen a phone so fast

[Q] Questions about undervolting Nexus 4.

Hello!
I heard about the term "UnderVolting" and I heard it would give me better battery life.
I want to do it but I have few questions before.
1. Is undervolting affects the CPU , GPU or Battery?
2. Can It damage the device?
3. Can it decrease the device performance?
Thanks!

1. It effects the cpu. When you undervolt you are reducing the amount of power that is supplied to the cpu depending on what speed the cpu is running at.
2. It is unlikely to damage the device physically but if you undervolt too far the cpu can start failing actions resulting in corruption, but the most common symptom is that it will reboot itself if you go too low.
3. Undervolting can reduce performance but going down -100 mv across the board is usually stable for most.

Is it recommended to undervolt?
I just want a better battery and around the same performance as it now.

You are confusing undervolt with underclock. UC is a proven way to increase battery, but it directly makes the CPU run slower. UV will make the CPU/GPU/RAM receive less milivolts, and it will only increase battery, and not decrease performance. The thing with UV is that if the CPU at any given time does not get enough power, it can't perform a given task, and your phone will reboot.
Sent from my LG-P760 using xda app-developers app

In a nutshell UV will not destroy your phone and is it recommended? If you are in xda then you know the risks or at least should read up on the risks. I would say 90% of the custom kernels are undervolted out the box and yes its a great help. I have been UV, UC and sometimes even OC for years now with no negative effects. Give it a shot and if you are worried start slow like -25.
Try mathkids kernel(JSS roms only) which is undervolted -100 and if you read the thread its never been an issue for anyone. I have heard that UV may cause some issues with Maps locking fast

I'm not Confusing undervolt with underclock.
Undervolting can and does reduce performance if you go too far. (Not far enough to cause reboots)
Underclocking is not a proven way to increase battery, in fact it's quite controversial.
It's called race to idle.
Pretty much all processors have great power savings at idle speeds.
By lowering the clock speed common tasks and background processes take longer to perform. Thus keeping the cpu at a higher clock rate (using more mv) for longer and overall using more battery than what it would have done at a higher speed.
From my own tests -150 mv undervolt resulted in slower and sometimes even laggy performance. -100 is great
Underclocking to 1ghz shortened my average daily battery life by nearly 2 hrs compared to running at stock 1.5
Say what you like about stats but these are the results I found from actual usage

UV will reduce how hot your phone gets.. and if your phone gets too hot thermal throttling will reduce the cpu speed.. and thus if u UV it will reduce thermal throttling and will increase performance..

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.

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.

Bump bump

is there any rom or kernel to under volt?

just bought a Le Pro 3 and couldn't find any kernel or rom that could under volt. is there any rom or kernel to under volt?. Thx

To undervolt you mean to make the cpu frequencies lower? I am doing that with a program called Kernel Tuner. You can set the CPU and GPU speed and set the CPU governor from there.
The phone it has to be rooted.

what i mean is to lower the CPU or GPU voltage.

I don't know how to do that. As I said, I use Kernel Tuner to set the maximum cpu/gpu speed the phone can go. It's not the same thing. But is better than nothing. The phone works really good even with lower frequencies and I don't need top speed except some greedy games. Now I can reach a sot of over 6 hours with 4-5 hours of heavy gaming.
If you can find a way do undervolt please post it.

No kernels offer access to the voltage table yet. UV isn't available and I don't think it'll come.

thanks for confirming, time to return the pro 3 or sell it at a loss. was just hoping that out there somewhere there would be a kernel that has the feature to undervolt.

I still don't see the point of undervolting the CPU/GPU on a phone. As long as it works fine and the battery last long enough (and honestly this phone have plenty of battery, I recharge every 2 or 3 days), why?

Because he used to do that on older device, and thinks this is some kind of a must function lol. I also have no clue why on earth you would need to underclock pro 3, it doesnt overheat, and it has probably best battery life of all snapdragon 821 devices. Undervolting this device would gain you absolutely nothing, nonsense.
