So i just installed a dualboot setup on my SGS3. I use primary rom the latest cyanogen mod 10.1 nightly and for the secondary rom latest omega rom 4.1.2. For kernel i use the latest one from Siyah. The omega rom i use for intense gaming, multimedia, pictures, music, comunications and so on, and the cyanogen mod rom i use for daily calling/texting use. The omega rom i left untouched in terms of undervolting/underclocking as i need the power (but i really don't see any reason to OC my cpu/gpu as it runs perfectly smooth). But i heavily undervolted/underclocked my CPU/GPU in cyanogen rom for battery life as the following:
1. CPU: running only 2 cores at minimum of 200mhz and maximum of 1000mhz with -100mV undervolting
2. CPU undervolting steps i left untouched
3. my GPU runs at the following steps:
108mhz - 800mV
160mhz - 800mV
266mhz - 825mV
350mhz - 850mV
400mhz - 875mV
My system is perfectly stable even after heavy benchmarking, i reduced it to a galaxy nexus level of performance. For daily use in telephony/texting/social media is more than enaugh. I am now doing a full charge and run only on cyanogen mod with average use and auto brightness (2 mail clients, watsapp, facebook mess, yahoo mess, hangouts, 3G allways on) and i will report back with the battery stats after a full discharge. Here are some screenshots for my under voltage/clocking setup:

But i must say the idea With dualrom is perfect. I think i will do this with revolt Rom for gaming and cm 10.1 for battery.

I did pretty much the same thing yesterday underclocking to 1.2 GHz and deactivated 2 cores. it didn't help at all though unsurprisingly, since the phone runs on low MHz most of the time (when doing some reading or other undemanding stuff).

try this one and let me know as i have undervolted a lot and my settings doesnt have any lag,
siyah kernel is really gr8. i have undervolted my cpu to -100mv and by checking cpu spy and analysing at which frequency cpu is working more, i have undervolted that frequency to -125mv
and gpu setting is
266mhz - 850
350mhz - 875
440mhz - 900
533mhz - 950
600mhz - 975
Touch boost - 600mhz

i find it out to be optimal good performance and better battery life.
You have lowered your GPU and CPU frequency to get better battery life compromising performance and i think by your settings u wud get max of more half an hour battery. I am getting nearly 5hr screen on time with my settings
Undervolting doesn't produce any noticeable battery gain. Your battery gains are probably from the fact that you use Siyah kernel.

i don't know exactly but i have set cpu freq to 1500mhz and gpu to 600mhz both of which are overclocked and undervolted producing bettery battery results. what i think and have read if u undervolt and overclock u might get better battery life with same performance.
and buddy i am regularly following ur post " Awesome Underrated Mods/Tweaks (24+ Battery Life) "
both adam kernel and boeffla kernel ( using zzmove governor) gives gud battery life results but my setting is overclocked and gpu to which would produce good result in 3d or heavy graphics gaming also.
i am not saying anything against but these are my thoughts and review.
I would like to know what u think. i am really a starter trying many things and need this community's support.

Thanks for the kind words. The most important factor in gaining battery life is the governor. Right now, zzmoove is the best. Boeffla, Googy, Siyah, Adam and Devil kernel all offer the zzmoove governor. As for undervolting or underclocking, it's not going to make a big difference so don't worry too much about it.
1500MHZ and 600MHZ is good.

You might have already figured out that HD2 can be overclocked as high as 1.5 GHz on its powerful Qualcomm SnapDragon Processor. Many people run their devices on default clock speed, but there are few of us who overclock their devices to get max out of it. So i have started this thread to know what your max clock speed is and what governer are you using. Post replies below. Also, don't forget to mention your Phone's Temperature if available.
Mine: 1.2 GHz On SmartAss Governer , Temperature Usually Around 95F

1305MHz using interactive, temp alway @ 28°C even when phone get hot?? tho alway careful to let it cool down when it feels too hot.
I have underclocked ... to 720Mhz (interactive)
Performance is okay and saves battery live
Temperature is about 28 celcius.
1267, 768 when battery less than 30%, 422 when screen is off
On-demand w/screen on, conservative when <30% and screen off
Not great on battery, but good performance an no wake lag
CPU Load jump or whatever it is, set to 30%
Sent from my HTC HD2 using XDA App
Sticks with no overclock
using a rom which is fast enough and saves battery life, Dont see a point that needed to overclock CPU
Undervolted to 576mhz, for better battery life.
Runs smooth enough for all apps, including navigation and games
No overclock for me, don't need it, phone is fast enough as it is.
Clock speed: 998mhz (default), governor: ondemand, temp: n/a
Good enough for me sweet onough on may battery.
P.s. there seems to be no difference(performance wise) between rafpigna kernel oc'd @1.5ghz and tytung kernel oc'd @1.2ghz, when testing on linpack and/or other smarbench tools
Please share
1. your favorite governor (do you use any different governor on different profiles?)
2. your voltage parameters
3. Your benchmark using quadrant
Thanks
No one wants to play?
Maybe like me, they have no idea what you are talking about
What is a governor?
What voltage do you mean?
My quadrant score is 3900 ish
Thanks for the reply, I don't think I'm good enough to explain but, in a nutshell,
A governor is a a piece of code in the kernel that decides on the cpu speed. each kernel has multiple governors
voltage is where you can decide what voltage is delivered to your cpu at certain frequency. undervoltage will usually help you save battery. we have to pay attention not to go too low or it phone will freeze
download setcpu it will all become clearer
I will give this another bump before letting it die
Even I would be intrested in sharing this
currently I am using CF root with ondemand and its working all good
FM kernel with interactive. I find my phone snappier with this governor. I liked it the most with smartassv2 on Abysssomething (don't remember now) kernel, but too many teething problems with this one, had to revert to FM. I'll give it another shot soon though.

Have you tried InteractiveX? Or, better yet, know the differences between the two? I am currently using smartassv2, FM kernel and have no complaints but would be interested if there was something a bit snappier when opening an app (I still get a bit of lag if I quickly select an app after unlocking the phone).
Yes, I've tried InteractiveX and OndemandX - they're both absolute rubbish (at least from my point of view). Both responsiveness and benchmark results were dismal (2800-3300 quadrant advanced). These are governors for anally retentive battery life lovers. Nothing wrong with that itself but beats the purpose when buying state of the art top shelf performance smartphone IMO.
Good to know. I appreciate the advice. Does that mean you also tried smartassv2 with the FM kernel? Any discernible difference between that and interactive, if you have? And sorry for all the questions but it saves me the trouble of trying them!
I just flashed the 1.3 FM a moment ago. Now running 100-1704 smartassv2, haven't played with voltages yet. Responsiveness in terms of screen scolling, lags & stutters seems better than 200-1400 interactive. Performance in Quadrant Advanced and Nenamark2 seems a tiny bit worse (but I don't really care about that, I use benchmarks only to roughly estimate, smoothness is what I'm after). I can't give you direct sources because I don't remember, but having spent several hours digging last weekend I concluded that for people who put performance slighly over battery life governors to be considered are interactive, smartass(v2), savagedzed and performance. Funny enough - I'm getting consistently worse benchmarks on performance governor on all kernels. I wonder why?
Thanks again. I will play around with some of the governors and settings to find the right fit. I think I will try savagedzen next but I am pretty happy with smartassv2 and may just stick with it.

i share with you my SetCPU config, voltage ...
it's very stable for me. It's not performance oriented but battery friendly.
what you think ?
EDIT : I use AbyssNote Kernel 1.2
I'm getting nice results here on FM Kernel 1.3. 1704mHz (1375mV) - 100mHz (775mV), lulzactive governor. 5000-5872 in Quadrant advanced, 32-35 in Nenamark2. Battery life good with low to med usage, poor when playing games, running satnav etc. - hardly a surprise We'll see about stability but so far so good.
This thread is finally picking off ! thank you all
I am currently on FM 1.3 and preferring lulzactive
I don't use any over clocking I guess I don't dare. is it safe?
I think i'm pretty aggressive with under voltage i'm running 1175mv at 1400mhz and 775mv at 200mhz. For some reason my phone freezes any time I use the 100mhz no matter the voltage .
Can you share the whole voltage for a comparison ?
with all this I can hardly get a full day of use with my battery but I guess I'm a pretty heavy on usage. no gaming or anything extensive but wifi-browsing-emails-3g-bluetooth all day

I read on some other kernel thread that Samsung's implementation of the 100mhz step is incomplete/buggy. That's probably why it doesn't work properly.
If any of you have OCed/UVed the GPU of the note, I'd really like to know your settings.
Right now I only have lock on 267mhz with -100mah. I'm a afraid to push further because I haven't seen people that pushed the GPU more. It was always about CPU.
flash abyss note kernel it has built in overclock of gpu
160mhz--950mv
267mhz--1000mv
300mhz--1100mv
you dont need to overclock it then previousely it had 400mhz step instead of 300 but it makes fone quite hot while playing games and if you want to overclock gpu without flashin your kenel or remainin at your kernel m assuming u dont have the abyss note then you can try voltage control extreme or tegrak but they will not have the 300 mhz step from 267 to 400 mhz directly. ..

I already know about abyss settings.
Anyway, I'm building for best battery life / performance. So I flashed Speedmod on Rocketrom. While overclocked to 1600mhz - 1300mah with 500mhz -800mah as lowest possible cpu power.
I think I'll try out 300mhz on GPU. How hot was 400mhz?
EDIT;
I can't seem to get 300mhz on tegrak. That sucks. Is 400mhz safe at all? I mean, I can understand it being hot but is it safe?

Nice, anyway. Is that lock on 400mhz? or not?
if not, are you on 267-400mhz?
setcpu does GPU oC/uv ? or do we have to use tegrak ? any issues if we use them both togather ?
@ clairenix
was little but not too much as you cant even touch but it eats up a lot battery if u not uv it .. while i been using rocket v22 with 3.7 abyss my battery is like m using some nokia fone its hell lot superb than ever before however i feel that rocket v21 together wid abyss 3.6 or 3.7 also gives best battery with superb performance and again its up to you but i feel abyss note has better battery life and hell lot better performance than speedmod
@hackerboi no dude as much i know set cpu does not perform gpu oc or uv nothing wid gpu only cpu oc uv profiles and governors .... how ever tegrak does all same ++ it can also oc/uv cpu but it has only 400mhz step after 267 nothing in between
no issues using together but y would u use both together ..i like tegrak more and voltage control extreme the most the app for oc or uv cpu and gpu
I'm already using SetCPU and have undervolted quite a bit. I want an app to play with the GPU settings
im running abyss 3.6c on performance at 1.4ghz no UV and i clear 20 hours a day easy on battery life, darkyrom 3.1 and i do use my phone thats not idle time

After more mods I just cleared about 10+ hours on dataplan browsing non-stop and games on the side @ 500mhz-1700mhz @ full brightness while using Rocketrom v22 + abyss 3.7. That says alot about performance/battery life you could get with enough fidling around.
That's pretty much enough for what I need but I wanted to experiment since I read that speedmod consumes less battery.
I gave up with gpu undervolting and speedmod for now. Since I don't have time for stress testing.
@ HACKERBOI try tegrak ultimate or voltage control

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.

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.
Hope this helps.
Thank to @DooMLoRD, we have a powerful customized kernel allowing to improve the user experience with our Z2.
Current version: DooMKernel (v11)
This is the place to share and to discuss about our settings (allowed by DooMKernel). Please don't flood the kernel thread with such information, the right place is here.
First, it must be emphasized that the best tools to enable and tune the settings allowed by DooMKernel are:
- Fauxclock
- FauxSound
However, you can use others tools (such as Pimp my Z1, ...) and your feedback using these alternate tools will be welcome.
Currently, I use these Fauxclock settings (Updated sections in red - 13 Oct 2014):
- CPU Clock:
Min freq.: 300 MHz
Max freq.: 2.458 GHz (overclocked, see FAQ in post #2 for enabling overclocking permanently)
Governor: Intelliactive
- CPU Hotplug: Intelliplug - Profile: balanced - Touch boost enabled, or mpdecision for better perf. (see FAQ in post #2)
Intelliactive + Intelliplug = good performances +, very good battery life +++
Intelliactive + mpdecision = good performances ++, good battery life ++
Lagfree + mpdecision = very good performances +++, good battery life +
- Voltage tuning: -12 mV
Beyond this value, my device crashes (not necessarily the same for all devices). Stability can be tested with StabilityTest or Antutu benchmark.
Reducing the Votage is interesting for power saving and thermal management.
From a few reports, you could be 100% stable up to -48 mV.
- Thermal manager: Intellithermal (recommended by Faux)
Better than Thermald for 4K recording (look at my tests here)
Temperature threshold freq.: 70°C (158°F)
Temperature threshold core: 80°C (176°F)
- GPU manager: msm-adreno-tz - 578 MHz
Try these settings for great GPU performance!! And please give feedback.
- Sheduler I/O (eMMC & SDCard): row
- Readahead size (eMMC & SDCard): eMMC: 2048 - SD: 4096
- Colour / Gamma: not tested
- Memory manager:
VFS cache enabled
Automatic mode for writeback delay: enabled
- Same Page Merge: Intelli-KSM enabled
- FastCharge:
Battery Temperature Throttling: on
Battery throttle cpu frequency: 2457600
Fastcharge options: disabled - not tested
Currently, I use these FauxSound settings:
- Preset Profile: Quality
- Speaker gain: does not work
That's all. All is working perfect for me.
Compared to stock settings, about 2000 points are won on the Antutu Benchmark Score.
These settings will be updated and discussed in this post from your future reports.
FAQ:
- How to enable CPU overclocking permanently ?
Open Fauxclock,
go to fastcharge,
enable "Battery temperature throttling"
search "Battery throttle cpu frequency" & set it there up to "2457600",
activate "set on boot",
go back to cpu/hotplug,
set cpu at max,
and reboot.
Thanks to @MysticEnforcer for this tip.
- You experience lags listening eXistenZ modded Walman+sound enhancements ?
Use CPU hotplug mpdecision.
I find my phone freezes on boot when I use the intelliactive governor with sio.

That's strange... What rom do you use?

Update of my settings: voltage tuning set from -48 mV to -24 mV for stability issues. Seems stable at -24 mV but needs confirmation.
Antutu benchmark is a good test to verify stability.

for me initially -72 mV was working but not stable... for now -60 mV is mostly stable, with a rare random reboot here or there

I was nearly stable at -36 mV with a rare random reboot here or there. Now, it's seems I'm 100% stable at -24 mV and I saw elsewhere that another user was stable at -48 mV. No luck for me... Anyway, all that confirms that each device behaves differently.
Stable at - 36

If you want to get rid of micro stutter, try using one of the following cpu governors:
Lagfree, Smartass V2 or Lionheart
Games, launchers, Chrome etc. became much more responsive since I've switched.

have you done any specific governor tweaks?
can you share them with us?

No, didn't modify them.
There are laggy governors like: Ondemand, Interactive, Conservative, Intellidemand etc. and fast ones: Performance (no good solution), Lionheart, Smartass V2, Lagfree.
Just try it. Made my phone fly. Games like Temple Run Oz and Asphalt 8, which were unplayable before are working fine since I've using another governor (currently Lionheart). Feels like a Nexus 5 or HTC M8 now. Much better than stock!
Thanks for your great work!

I think I'll share my settings. This is not for those who expect ultimate power from their Z2's. I'm not a gamer, so this settings are for browsing the web and focused on battery performance.
Here we go:
Underclocked to 1728 ghz, governor intelliactive
CPU Hotplug: mpdecision (there's nothing we can do about that )
Voltage: -24 mV
Thermal: Intellithermal, frequency throttle 70 C, Core throttle: 65 C, all cores throttled
GPU: msm-adreno-tz 578 mhz, gpu rendering: on
I/O Schedulers: SIO for internal and external, cache 1024
Memory manager: Clear VFS cache after boot, rest on stock
Same Page merge: Intelli-KSM enabled
Low Memory Kill: why do i need those with 3gigs of ram?
FastCharge: Battery throttling: throttle at 50 C of bettery - throttle to 1267200
Battery lasts from 7am to 10pm with heavy use - 40% left. Stamina mode on all the time. Screen with auto brightness.
I'm using fauxClock. Smooth UI, fast browsing, no stuttering, fullhd camera works like charm. I'm not using 4k recoding and I haven't tested it.
Stable at -60 mv..

Is it better to turn mpdecision on or leave it off? I read somewhere that mpdecision overwrites the cpu governor settings.

It's better to turn it on as there is no alternate manager for the moment.

How you turn on the GPU Rendering?
From Developer Options? Force GPU Rendering?

In your opinion, what advantage is there in turning on GPU rendering?
I had tried it with my old Xperia T, but I hadn't noticed any difference...

@DooMLoRD
I've done several tests comparing different governors in term of power consumption. My screen was off and I was listening to music with Walkman.
Results (discharging rates):
Intelliactive: -2%/h
Lagfree: -3%/h
Lionheart: -4%/h
Smartass v2: -12%/h (big issue: freq. always at max)
So, Lagfree and Lionheart are probably more performant than Intelliactive (based on Ondemand) and more suitable for gamers but they are far more power hungry. So, this must be considered before choosing a governor.
There is patently an issue with Smartass v2.

Have seen the same, Smartass V2 is buggy and keeps the frequency at maximum (just like performance governor does).
Lagfree seems to be the best compromise, it works pretty well in games.

I think that Interactive should be good for games and not too power hungry. However, presently, it seems incorrectly parametirized: using it, I can hear few scratching noises listening to music in Walkman (and also with Ondemand)!! I'll see what I can do.
