Hi there,
I want to get the most performance out of my old galaxy s but i have a slight problem with 4.4.
I came from Slimbean android 4.3 on 1.2ghz because it worked really slow and gave me alot of problems.
I first flashed (After full wipe) to Mackay 4.4 rom but whatever govenor or sheduler i am using it crashes everytime after a minute or so doing some simple tasks from the slightest overclock (1.1 ghz).
So i flashed to CyanAOSP (full wipe) to see if it would fix the problem but the problem still exist on this rom :c
Is there something wrong with my device?
Greetings,
- Merlin
Taking the phone to pieces and applying thermal compound to the chips gave me another 100Mhz. (rock solid at 1200Mhz when 3D gaming etc). There are 2 chips underneath the motherboard, and if you remove the sim tray from the board there are another few under there. I did them all. Be very careful if you're using Arctic Silver. I would have preferred to use the cheap white stuff but I didn't have any. There is a thread if you search for it with instructions on how to do this if you need it.
And with overclocking there's an element of luck. There are variations in the manufacturing of the chips themselves which can make your particular phone good (or useless) for overclocking.

But why could it do 1.3 ghz on android 4.3 easily? I think it has nothing to do with heat atm.
Because sometimes i can run antutu for 2 times in a row before it crashes. But sometimes it crashes instantly when i press the start button.

It's kernel related issues. I managed to clock in at 1.6Ghz rock stable on CM 10.2 but likewise, a 1.2Ghz overclock on 4.4 is giving me very rear soft reboots

Ah ok now that i know that, its probably going to get fixed sooner or later
Interesting. Mine is stable at 1.2Ghz on 4.4, so I'll be trying to push it a bit more when I get new kernels. I put Arctic Silver on all the chips the other day, even the ones under the sim card tray so hopefully that will help it. It has defo done something because my phone was unstable at 1.2Ghz before I did it.

I just flashed to semaphore kernel on mackay rom and it is fully stable on 1.3 ghz atm.
Is there a 4.4 semaphore kernel?
Sent from my GT-I9000 using Tapatalk
Guys , every kernel has its own custom voltages for over clocking . just use an app that controls the voltage (you can find one in play store ) and increase the voltage step by step until your phone is stable. For example : on Mackay I can't over clock not even to 1100 MHz with stock voltages without the phone rebooting after a few seconds but on Semaphore I can oc with stock voltages up to 1200MHz and its stable . on Mackay I messed around with higher voltages until I found the ones that my phone is happy with and I could oc up to 1300 MHz stable after that.

Yes there is , check the Semaphore thread for 3.4.0

I didn't realise that voltages were set in a kernel. Thanks
Do you know what voltages I should be using for a 1300 or 1400 overclock? I'm sitting stable at 1200 at the moment, how much do you think I should raise the voltage to keep it stable with another 100 or 200 MHz increase?
Edit: I'll try the 4.4 semaphore kernel
Sent from my GT-I9000 using Tapatalk
I personally use these settings:
Frequency - CPU - Int
1000MHz - 1225 - 1100
1200MHz - 1300 - 1100
1300MHz - 1350 - 1100
1400MHz - I've never got stable 1400MHz OC :/ (I think 1400 1150 should be right for most devices)
Optional:
1100MHz - 1250 - 1100 (some kernels have this step)
Thanks again, that's me running rock stable even under gaming at 1.3Ghz. Not tried 1.4.......yet lol
Why is there two voltage values you gave for each clock speed though?
I used setcpu, and set the first value. I'm not sure what the other value you gave is? GPU voltage?? Thx

Second value is internal voltage (mostly used with LiveOC to stabilize as it gives voltage to GPU and RAM). With normal OC it should be at stock (1100mV). Some apps, like NSTools gives you opportunity to change those.
Normal OC affects CPU, and liveOC CPU, GPU, RAM, so it's more likely to be unstable. I can't reach 1100 on LiveOC, but on normal I have 1300 easily.

Heh there are no two same devices. One overclocks better and one at all. There are devices which can't be overclocked. It's just luck you have with your hardware.

What CPU speed and voltage suits you the best?
-100mv on all clocks, 1.2ghz max. No lag.

I am currently tsvz111 der Kernel Trinity at 1400 and I am not very undervolted. I highly recommend Trinity - if you want more power get a96 which is 1600 max i believe. a96 and other builds might max at 1700 I forget which. Also the inexpensive Trinity Tool kit app.
I was coming to ask what stock voltages are because I have reboots when too under voltage.

Refer to the system tuner app for recommended voltages
here's a question. I am running trinity a96 i believe; and I'm trying to keep my device running at minimum 500mhz up to 1.5ghz. However, everytime I turn the device off and back on, it goes back to stock clock speeds. Anyone know how to fix this?

Sometimes the tegra 3 has a mind of its own. I had that problem with every kernel I tried before giving up. What you can do is set an init.d script to set the clock speeds
But I have Faux's 009es kernel, which comes at 1.2GHz and I have just left it. Tegra 3 does a good enough job at handling performance by itself imo
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.....

Hey there ,
so i wanted to share share my awsome Undervolting results with you
At first im running on Chasmodo's latest CM 10.1 i really appreciate his work ! I use the latest CM 10.1 Kernel.
With his rom and this voltages u find under this introduciton text i could get nearly a month with Standby time
(without doing anything , Wlan turned on , Data off) i attached a screenshot (29 Days and 5 Hours sorry for the German language)
Every day i plug my N7000 out from the Loading station its 5am on 3pm i lost 1%.
to change the Voltages i use SetCPU (full version)
1400 MHz
1200 mV (Stock: 1350mV)
1200 MHz
1100 mV (Stock: 1275mV)
1000 MHz
1000 mV (Stock: 1175mV)
800 MHz
925 mV (Stock: 1100mV)
500 MHz
900 mV (Stock 1000mV)
200 MHz
800 mV (Stock: 975mV)
So i dont know my Voltage group sorry guys , if this values are not working just go in 25mV steps lower from your stock voltage
until the CPU gets unstable or crashes than u know that u cant go lower just do this with every clocking !
I also used this voltages on XXLSC Ultimate Rom with the HydraCoreNirvana Kernel i had fantastic results too but not that good like i get with the Asylum CM 10.1.
PS: Just this Voltages wont give you very good Battery life if your Rom / Settings is/are eating your battery. If you get better results with
lower results (stable) just go ahead and post it but im sure this values are nearly the lowest stable u can get
Code:
Its [U]impossible [/U]to hard brick your device with Undervolting , you only could get a soft brick if you use (Set on Boot) and your voltages will crash your System after boot. thats easy to fix just after the phon booted up fast go into SuperSU and delete the root rights for your Undervolting tool.
Thanks for Reading and if i you liked this push the Thanks button =) !:victory:
Thanks man
I think you should say which Voltgroup (A, B or C) your note is. Because those freq are really low (I think too much low for my note, that's voltgroup B).
Do you remember which voltgroup has your note, when you installed hydracore kernel?
Better i would buy a spare battery rather than spoiling my devices performance. We arr not in 1000BC with no electricity. Sure every one can charge a spare and can switch it.

It's a feature of the hydracore kernel only I think, because its read a particular value (something about mainboard and/or cpu) and the kernel automatically apply dedicated undevolt values. You could see it in system information, where hydracore kernel is detected. Without it, I think you can't do anything :/
Anyway, sincerely I remember some time ago I tried to lower my already undervolted cpu voltages, and I got freezes. I will try to go lower a bit, hoping it will works. A very important thing, is not only the lower battery drain, but also the lower cpu temps.

never had any problems and just logical cpus could brick if you give them too mutch voltage , if you give them less voltage the system only can crash your sound could have been beacuse it crashed so really u cant hard brick your device with undervolting ... maybe a softbrick if your unstable voltage settings are on autostart.

Hey there , you cant uv with Philz kernel just read his thread check his FAQ there hes writing that hes not supporting
oc/uv its just a repacked stock kernel
use HydraCoreNirvana but when you download the kernel check that its the OC version if not than you cant change your voltage like with Philz kernel.

You can you can
Just use tegrak ultimate Overclock app. I bought it because I think it's the only who give you the possibility to Undervolt the gpu also. Initially, philz kernel wasn't supported, but now it is. I undervolted my cpu setting the values that I had using the hydracore kernel oc. And today I lowered them of another - 25mV also. Everything works nicely until now

Better i would buy a spare battery rather than spoiling my devices performance. We arr not in 1000BC with no electricity. Sure every one can charge a spare and can switch it.

Nice attitude you are showing there. Oh, there is plenty of power, let's waste.it! Really, that kind off attitude is definitely going to make the world a better place
What's more why do you think undervolting does influence the performance? It only influences the power consumtion and if you go too far it does render the phone unstable. But it certainly does not in-, or decrease the cpu's performance.

Yep tegrak definitely does the trick with PhilZ kernels. I have been using it for at least 8 months now and my phone is undervolted too. Only the highest cpu state is overvolted because I overclocked it to 1552 MHz instead of 1400.

I would love this kernel under ubls4 if it has a proper exfat support. Until this is not fixed like philz kernel, I can not test or try

Please explain why you overvolted AND overclocked the highest cpu state. Doesn't this shorten your batteries performance?
Did you changed cpu governor or something else (like screen off profile to reduce CPU) to achieve 1% battery loss at 3pm?
And was that with mobile data on?

I overcloked the highest cpu state from 1400 Mhz to 1552 Mhz because I want more performance. And because my phone became unstable with the 1552 Mhz and the standard voltage. So now my phone saves energy when the lower cpu states are active and it has a bit of extra power at the expense of battery life when it needs the most processing power. All in all that gives me better battery life than with stock settings and a snappier device when needed. For me this is the ideal solution.

Hi all,
I tried lots of combinations to OC my i9023, without any results.
I currently have CM10.1 Nighly + Marmite 7.3.1, which actually seems to be the fastest combination for me.
Btw, if I try to OC to 1096 or 1320 it starts rebooting.
Everyone said me to raise voltage.
I'm using NSTools and it appears that Marmite 7.3.1 already has higher voltage for 1096Mhz and 1320Mhz.
Furthermore, there are two settings: ARM Voltage and Interal Voltage. Should I increase both of them?
Are there other people with 9023 which overclocked it succesfully? If yes, with which tool and voltage settings?
Thank you
I have my i9023 Nexus s OC to 1512Mhz STABLE.. no random reboots or something.. my battery goes easily one day even with lots of gaming.. I use NSTools.. (my snapshots are from SetCPU.. ;p )

With that voltage @1500 you will probably burn the cpu fast...i think. Maybe someone with better knowledge can advise you. But i wouldn't keep such a high voltage on my phone

It really seems too much high...
Btw, which ROM and Kernel are you using?

On marmite i've never been stable on OCs, even with raised voltages. On matr1x kernel you can do 1320mhz without raising voltages.

I am using Hellybean (the latest 26/2/13) and my kernel is Devils's kernel NOT the latest but the 21/12/12 release.. this kernel is my favorite.. try it out.. works on 4.1.x, 4.2.x.

I really don't care about burning my cpu. I have my photos backed up with dropbox.. and I'm on contract with my carrier so I will get it fixed within a week..
Is there an official thread/page for Hellybean and for the kernel?

There is a thread on XDA for the ROM Here.. For the kernel there is also a thread on XDA Here, but I don't think that you will find that specific version, just download it from my attachment above..

I have tried it and set it at 1320 (with LIVE OC 110%) and it seems stable.
Why do you suggest that particular version? Have you tried new versions and they are not stable?

I have tried all the new Devil kernels and they are stable for every day use but not as fast and battery save as the older version.. This is my opinion.. I have my nexus clocked at 1400Mhz and then apply 108% LiveOC witch took me to 1512.. Stable..! (at max arm volt 1500 mV)
Currently looking into the process of OC'ing and UV'ing. It would be cool to see what results you guys have got and what difference in battery life you perceive!
Im currently at stock ?

I have the same PVS CPU than you with 0,9 Volt at 384Mhz and 1,05 Volt at 1,5GHz.
I could undervolt 50mV accross the board; undervolt the lowest frequenz (384Mhz) to 0,73 Volt and overclock the CPU to 2,0Ghz max.
Im running Cyanogenmod with Glitch Kernel and use Trickster Mod for OC and CPU UV.
With Glitch Kernel I can even undervolt the GPU 100mv accross the board with an increased max GPU of 450Mhz.
(More is possible, but I nearly dont play games with my tablet)
With this I get about 8 hours of SOD time with Surfing.
When I'm on a long business trip and use my N7 for (Kindle and pdf) offline book reading I reach something like 13-15hours SOD time.

I know a bit how i can get to know my cpu's pvs stepping, but since you have the same as me, what is it exactly? And is it considered a fast, normal or slow binned cpu?

Whats the best way to test stability? Ive got this app https://play.google.com/store/apps/details?id=com.into.stability but i dont seem to get any wiser... Anyone know what i should do?

yup, run that for like 30mins on classic test, should be fine if it doesn't crash

I did that, but with voltages that are stable there, antutu crashes. And with voltages that are antutu stable, my device crashes randomly. I can run the scaling test with very low voltages across the board for more than an hour and it doesnt crash.
With other apps it just crashes.
This is an experimental undervolt that rarely crashes when switching apps:
I dont know which clock speed and its corresponsing voltage is unstable because the clock speed ranges from 384 to 1512 mhz and i dont have a crash log.
So I added 12.5 mV across the board, and this hasnt crashed so far!
But, being the perfectionist that I am, I want the Ultimate Undervolt. Is there a way to see what frequency you are running when it crashes?

I achieve stable 700mV at 1026MHz...
30mins stress run on "stability test" app and on stress run on "setCpu"
At 1134MHz the tablet freezes for the first time when I switch to 7875mV
Isn't it weird??
I dont think the stability test app is working. I could undervolt 1512 mhz to 900mV and have it run stable, but everyday use stable is with 987.5mV

Will you post your voltage table?
What are the Kernel setup settings that you choose and have you ever OCed to 2.2 and still get good undervolting?
