You should share what speed and voltages you are running at, I figured it would be helpful to give other people ideas of where to begin trying their voltages at for undervolting purposes. So, what's your lowest voltages at the highest clock speeds?
I'm using SetCPU's standard voltages. 1.8/.38 normal, .87/.38 screen off and over 130F, 1.2/.38 battery less than 50%, 1.8/1.2 plugged in. Getting 4-5 more hours per charge!

Here's the values I've currently got in my Permatemp Root .bat file (thanks Eugene!): scpll_l_val=24 vdd_uv=1060000
That gives me 1.296 ghz at 1.06 volts. I know 1.3 ghz isn't much of an overclock, but this phone is already so fast (especially compared to my old Hero, lol) that I'm not really craving any more speed ... what I'm most interested in is undervolting for max battery life. From what I've read the stock voltage at 1.2 ghz is 1.18 volts, so I'm a little under that right now. I tried 1.00 and 1.03 volts and got reboots every time, but 1.06 volts runs rock-solid reliable for me at 1.3 ghz.
is that really even noticable? the LCD draw most of the power typically

Someone in the OC topic was asking about UV at stock speeds. You're close enough to stock that you should qualify. You should go post your results in that thread too. They'd be happy to see them.
I'm running @ 1.78GHz with a vdd of 1300000. I'm going to try and go lower... maybe 12800000.
I have it overclock to 1728mhz but dint know where to adjust the voltage. Does setcpu does this or i need a different program to read voltage/change voltage?

You adjust the voltage when you type the ADB command to OC. If you're using a script that does it for you, you will need to edit that script and look for the vdd_uv= line.

What do you mean by "is that really even noticable"? It's certainly calculatable ... it's an 11.3 percent improvement in battery usage by the CPU. If you're saying that's not very much, well, it's all relative. If you're saying you're not interested in saving a little battery when it won't cost you anything to do so, that's fine with me. If you're saying that no power-saving effort is worth any consideration because the LCD is the biggest power draw of all and that's the only one that matters, then why did Qualcomm bother to develop asynchronous cores and low-power audio modules and low-power GPS modules? I mean, hey, the screen is all that matters, right?
Or did I misread your statement?
Edit: Sorry for coming across as so argumentative, I just don't understand why you're taking the position you are.

+1! Would have thanked you, except I'm at my limit.
I'm at 35 @1450000. I know I can go lower, but if I overclock, I want stability not battery life
On another note: I can't wait until we have source, custom kernels, and I finish up the viperMOD app to get support for the E3D. Will be one awesome beast undervolted!
I'm at 1.56ghz and 120000 voltage.
Runs stable, get a nice speed boost without killing my battery. Am going to try a lower voltage. I've read the could will default to stock speed if you go too low though. Guess I'll find out.

I am currently testing scpll_l_val=22 vdd_uv=1010000 for undervolting purposes, 1000000 caused a reboot, 1010000 has been holding up well under stress tests..
If one of you guys who are overclocking could test this video clip and either diceplayer or the diceplayer free trial in the market - I would appreciate it:

Supposedly - the Samsung Galaxy S2 can play 1080P + AC3 MKV's smoothly. But the Evo3D and Sensation lag a bit according to the developer. I tested this file with my evo3D and it looked like my Evo3D stuttered every 3 seconds or so. I'm just wondering if an overclock would smooth out playback - but I haven't installed temproot.
For those of you overclocking just for battery savings, I am currently testing
adb shell insmod /data/local/tmp/8x60_oc.ko scpll_l_val=22 vdd_uv=1003100 and have been stable so far, this is the absolute lowest I can push it at 1.2Ghz on my phone, can anyone else match this or go lower? I think it will be helpful to start establishing these values now so kernel makers will have some ideas of how far they can push our phones.

Speed = 1.5GHz.
The default gallery player plays it perfectly, but there's no sound.
RockPlayer plays it very choppily, but has sound.
Dice player plays somewhat smoothly and has sound, but there are lag moments every 3-6 seconds as you said.
It's a software issue.

Right noe I'm sitting at 29 (1.56ghz) with a UV of 1170000. Tried 1150000 but phone immediately restarted. And 1160000 restarted after a while. This seems stable so far. Haven't totally stressed it yet though.

Thanks for the check! I was wondering if there would still be lag with an overclock - that's disappointing. Supposedly the SGS2 handles files like it with no problem.
OC Script
Here is a batch file I created to make it easier to OC. Basically just the Rooting script with a menu to select the speed with delays built in.
Rename from oc.txt to oc.bat if you wish to run the file.
You will most likely need to change the voltages to match your phone. My phone has been very OC friendly.
Currently running 1188mhz @ .97 Volts with no issues. I have been able to OC up to 1890mhz @ 1.32 volts.
Have not tried to go lower on the voltage at 1188mhz yet...

I installed the webtop over hdmi mod on my Atrix and while testing it out, it got very warm in my hand. I opened the setcpu app and noticed that while overclocked to 1.3GHz, the CPU was running at 75C! I lowered it back down to the stock 1GHz and the temp slowly went down and settled at 63C.
It seems that while in webtop mode, the CPU is taxed at 100% all the time so I'm wondering if it's safe to stay overclocked when using webtop.
Everyone has different opinions of what is too hot around here.
IMO the cooler the better. IMI No Atrix should have a temp above 60c and I'm not even comfortable with above 50c either...

I have experienced the same problem and worried that something may fry.... I have had mine overclocked at 1.45 using debian linux and all of a suddent he phone freezes and restarts.... Since it did it to me the second time I have kept my phone at 1Ghz... I am new at this so please don't beat me up too bad for being a noob... Just want to see if maybe undervolting it a little might help or hurt it?
Thanks in advance
Here are some tips I can offer
1.Try re-flashing your custom kernel and see if that fixes the web-top thing and over heating
Whenever the phone is plugged to the web-top it will naturally overheat so it's kinda expected remember now it's gotta work harder since its displaying on lap-dock or TV,but if you can cook an egg on it it might be too hot...lol
2.Set profile for temperature on setcpu so this way once you reach for example 100F your phone will clock down a little and so it might help the heat issue.You can set even more than one temp profile so this way when it reaches 96 it goes down a little then when it reaches 100 it will clock down a little more and such.
3.If that doesn't help,which in my situation it did.Flash a different kernel mayb it's just the one you're using that is causing funny stuff to happen.
Edit: not sure but i think undervolting helps battery but causes more heat,I myself don't undervolt I just created litterally a bunch of setcpu profiles for battery level,screen off,incall,charging,temp,and time and I'm getting 13 hour days at 1.3Ghz and temp profiles have been helping by clocking down when it's too hot therefore saving battery and drastic overheating.I dontlike my phone going anything over 104F it gets me paranoid,but that's just me.
I tried reflashing the kernel but it didn't change anything. I'm using Faux's 1.3GHz overclock kernel for Gingerbread (2.6.32.9). Is there something else I should be using?

Do what sktrix said in rest of his post.
I use the stopgap 1.0GHz kernel, and UV does lower temperatures. I would definitely try UV'ing a wee bit. You don't need to go crazy. I am using the following with great results for both temp and battery life:
-50
-50
-75
-75
-75
-100
-100
My setcpu profile clocks it back if I reach 60C, (I idle in the low to mid 30's). Under heavy load I reach around 52C max which is quite acceptable.
Now, granted I am not using Webtop, but the end result for UV should be the same. Lower temps and better battery life. You may also want to try just using 1.0GHz when on Webtop. The phone has more than enough power at this clock speed.
There is a bug with faux's kernel that causes the webtop to clock the phone at max speeds until restart.
Sent from my MB860 using xda premium
I know I'm straying from my correct forums here, however I have an LG Optimus 2X which like the Atrix, is a Tegra 2 CPU.
Our phones get VERY hot, I have had my CPU up to 86C before I decided to back off the stress test. CPUs are very good at handling high temperatures, and IMO you will see no ill effects from doing so, I am unsure of whether or not the Tegra 2 has thermal throttling/shut down, but in my experience they should be fine to around 80C.
The only issue I can forsee is the battery, batteries HATE high temperatures and it is awful for their life span, this is why your laptop batteries turn to crap after 1-2 years, even if low charge cycles, because they are always hot.
I would not be concerned about anything in the 70C realm, at all.

Experienced this countless times. More with the latest 1.45Ghz, but it did happen on the previous release. When I dopped the mhz with setcpu, it wont scale but stay at max cpu. It even did it a few times without using the webtop.

So which overclocked kernel is best for webtop? I too have noticed where the CPU hangs at 100% at 1.45Ghz for a while when disconnected but it is always there when im in webtop mode.... How is Faux 1.3Ghz kernel with webtop?

It will still hang at 1.3ghz, though it's a known bug. I just stick with the 1.0 enhanced, there's no noticeable real-world difference from going over 1.0ghz anyway, it's just a benchmark gimmick. Right now, the software that's out there is optimized to run on existing hardware w/o overclocks. I've run Shadowgun at 1.45ghz and didn't see any difference over the 1.0 enhanced.
Now, if we were trying to run games that were coded specifically or faster-paced chipsets then we'd need overclocking to catch up much like you would in the PC arena. That, however, is not happening in the cell phone market just yet.

Read the history at the following:
http://forum.xda-developers.com/showpost.php?p=15387385&postcount=1
You will see a lot more optimization than just upping the clock speed. One of the reasons the 1.0GHz kernel works much better than the stock kernel. Also, the ability to undervolt saving battery life.
IMO there is no need for 1.3GHz or 1.45GHz in everyday use of a phone. The only benefit is for OC'ing bragging rights. Until we can control phone temperatures better, it's pointless to risk the substantial heat increase on ALL internal components for extended periods of time which results from much increased CPU temperatures.

I see... guess that explains why the phone doesn't really feel any faster when it's overclocked. I'll flash the 1GHz kernel then.
Thanks for the info.
Not sure if this is the same with phones but normally a CPU should stay at 40C idle and 50C load. Maximum would be 60C while benching or something.
If it goes above that I would definitely underclock/undervolt.

also has other fixes besides overclocking you can go read them in the kernel threads
First I am aware that overclocking is not "safe" and all that kind of stuff
However for some reason I am unable to OC my SGS2 and run the phone on a steady way.
I have tried several ROMs (stock and custom) with different kernels and OCing apps with no avail.
I am not even able to run at 1.4Ghz or 1.6Ghz without having my phone reboot or hard lock on me.
Is there a particular or recommended setting (most successful combination) that anyone out there can suggest me trying?
Sometimes it will hang under heavy gaming but sometimes even browsing app and regular stuff will cause the phone to reboot or lock. If I work with no OCing at all then everything is fine and dandy.
Thanks, you can see my current configuration @ my signature.
Sounds like a very temperamental cpu. Currently I have the same setup you do and have never had issue with 1400mhz or 1600mhz. Though I usually leave mine at 1200mhz. What app are you running when it hangs?
And just as important, do you have alot running in the background? The modified touchwiz launcher unnamed comes with can be enabled to show a red dot next to the apps that have been opened and are in the background.
If you could list the apps with the red dots.

Not all CPUs can overclock - there's a reason it was sold as a 1.2 GHz chip.
Well as I've mentioned before, it could even hand when browsing through my apps menu, browsing the gallery, playing a game (non in particular) and the funny part is that the phone is not even hot to touch.
What I know for sure if that if no OC = no hangs, no reboots.
I do have the App monitor widget that comes with the stock ROM and currently using it on UnNamed 1.3.1 and I only have Widget Locker App. However I have try closing it and still will happen.
Not sure if maybe this CPU is somehow having an issue that makes it unstable as soon as I OC it.

Now that is new to me, I thought that all of them were OCable. Is there anyway to identify which can be or not OCed?
nope.. just by testing. it does have to do a little bit with the kernel and rom. the roms didnt originally have stable OC. i would assume that all of them do now. one thing you might try is giving them a little more voltage (just a little) at the higher clocks, but be careful. if you increase the voltage that means that you will sink more enery through the cpu and it will get hot quick. make sure you watch the temp.
i find that setcpu is less stable than the built in cm7 oc menu but cm7 doesnt have a voltage menu.
but on the same token... why OC? i can and i did but i dont need to... everything is like butter and i didnt see that huge a gain by OCing it anyways

have you ever overclocked PC CPUs? if you have spent much time doing that, then you would know that not every chip, even within the same model/family, will clock the same. take 2 CPUs, from the same batch, same model, with identical hardware tied to them. you will probably find that one clocks higher stable speeds than the other.
its very likely the proc in your phone just cannot handle the overclocks that the next person's could.
Like pirate said, no two pieces of hardware are identical. Sort of shows how much variance there can be in a manufacturing process. Id guess theres a few chips that come off the same line that arent stable at 1.2 ghz, but they dont make it to the devices, whereas one that can handle a higher clock will. (No sense tossing one that exceeds minimum requirements, thatd just be throwing good hardware away)
You could try nudgin the voltage up and seeing how it behaves, just use caution.

To get mine to overclock to 1.4 and 1.6Ghz I had to actually INCREASE the voltage settings via Voltage control app. So my settings are: 1.6Ghz= 1475mV and 1.4Ghz=1325mV
Try those out and see if is better for you. I tried undervolting the higher voltages and would either lockup or reboot instantly until I tried adding voltages. So you may need to play with your settings to get it to work for you.

Yup, or if they want to sell a "premium" device with a higher clock rate, they will take the parts that test well at 1.4 and sell them as such - meaning parts rated 1.2 will be LESS likely to be overclockable if a device comes out with CPUs rated at 1.4 - like the Galaxy Note did.
Before, anything that could meet the requirements of stable at 1.2 was sold to any Galaxy S II - but now, the premium parts are going into the Note.

I am having the same issue as the original poster on my new GS2. I will have to try the settings you mention but would it be possible to do this and also apply /UV to the remaining lower (1000ghz to 200ghz) processor speeds and maintain stability?
So I overclocked my GSII to 1.6Ghz, and ran benchmarks and it was blazing fast. So what's the point of overclocking other than running benchmarks? I'd rather not have my processor running at 1.6Ghz all the time and draining battery power. I actually prefer underclocking to save power. So my question is - how else can I benefit from overclocking my device?
yo whyd you put this in the dev section? get flame suit on brotha.
miui+siyah = beast
Well its obviously to have your device performance better. Honestly it's not really practical to run higher than 1.2 ghz though.
You also put this in the wrong section. Prepare your anus.

But in what ways other than benchmarks? Am I really going to notice a difference if I kick it up to 1.4 or 1.6Ghz when browsing the web or playing Angry birds or something?
where is the download link and what does it do?
Some serious development going on here.. [\sarcasm\]
OP even if you crank it up to 1.6GHz, unless your isolating that step, your phones not using that clock speed unless your doing sh*t on your phone. It will increase how fast apps or menu's open navagating throughout the phone. Your making the CPU think faster so your phone ends up doing its tasks little and big ...faster

The benefits of overclocking you ask? Let me tell you just a few.
1. For every overclocked phone, one dollar is anonymously donated to poor and starving children, families, and college students across the world [citation needed].
2. Overclocking your phone emits a low frequency gamma wave inhibitor which in some cases, tested by prestigious scientists, has proven to protect you from harmful UV rays from the sun, nuclear fallout, increases neural synapse action in the brain, lowers bad cholesterol AND blood pressure, increases lifespan up to a minimum of three years, and is a natural antimicrobial agent that also interacts with your white blood cells to not only increase output and strength, but also breaks down the DNA rebuilding process by inhibiting protein synthesis in a wide variety of foreign microbes in your body.
3. Overclocking has been used to successfully treat sever depression, obesity, dementia, and AIDS.
4. With an overclocked phone, it's been observed waiting times for and inside elevators is severely decreased.
5. Bad driver? Accident prone? Overclocking has been shown to heighten driver awareness and overall skill.
6. It speeds up your phone on a day to day basis, with some, but not terribly noticeable battery drain [citation needed].
Sent from my SAMSUNG-SGH-I777 using xda premium
Overclocking is entertaining. But I'm running the Unnamed rom on my device and have it UNDER clocked to 800mhz. Crazy good battery life and zero lag.
Overclocking is pointless as it runs everything great already. I'm waiting to overclock until my phone is outdated and my contracts about to expire.
While its rather easy to do there really isn't any benefit to overclocking the SGSII. Yes, it'll run a little faster and your Angry Birds might run smoother (really? ), but it'll also mean a little more heat and more battery drain all to accomplish something you really won't be able to get any real advantage from.

Only reason in my opinion lol...

For this phone, it's pretty much useless. The phone runs great without the faster clock speeds.
On the other hand, if it was a snapdragon processor, you'd need 1.5 GHz just to be marketable next to this phone (and 1.8GHz to perform as well in day to day usage.)
One reason could be... Because we can!

So I overclocked my GSII to 1.6Ghz, and ran benchmarks and it was blazing fast. So what's the point of overclocking other than running benchmarks? I'd rather not have my processor running at 1.6Ghz all the time and draining battery power. I actually prefer underclocking to save power. So my question is - how else can I benefit from overclocking my device?

Most people overclock for a smoother/snappier experience. I notice that roughly 20% increase in scrolling/tabbing around. Also you can think of it like this:
1.4ghz will finish tasks faster then 1.2, that way taking less battery. You could also undervolt that 1.4 to 1.2 (1275mV), so your finishing tasks quicker while draining no more then stock.
I switch between 1.4 and 1.0 every other day it seems. 2 months later, still looking for the right one for me. 1.6 should only be for benchmarking imo, epeen.

It's not that simple.
There are dozens of bottlenecks in these devices (and any other computer), and 9 times out of 10, it's NOT the processor. Persistant storage, RAM, bus speeds, etc - all those things will ensure that a 10% bump in processor speed will NOT give you a 10% decrease in run time for a given typical application. In many cases, you'll see no speed increase at all, as it takes the same amount of time to flush to persistant storage no matter how fast the write cache fills.
I'm not suggesting that a person shouldn't O/C, but don't be surprised when going from 1200MHz to 1400MHz makes no visible difference other than the battery draining slightly quicker.
I know someone is going to respond that the processor will bump back down to a slower speed and therefore it runs at the higher speed for less time, etc. However, unless you have the governor set to poll for usage so often that the governer is driving your clocks up to max, it's not going to poll often enough to make much (if any) difference.
Think of it this way: We both own a mustang, but mine is a V6 at 220HP and yours is a V8 at 300HP. In theory, yours can accel faster and maintain a higher top speed. In reality, neither one of us can go faster than the car in front of us (but you'll burn more gas doing it.) (Of course, you'll have more fun in yours.)
I hope this helps with a very common misconception.
Take care

Very true. Also I am guessing in gaming, that OC will drain your battery quite well.
Consider I mostly do Web browsing on my phone (I need a tablet), 1.4 is a much better browser experience imo. Worth the 100mV.

While for now Overclocking is mainly just done for fun im hoping that closer to my upgrade time that i will be overclocking for more actical reasons. That is the way it was for my Captivate. I enjoy trying to push my hardware to its limits. Ive gotten my GSII so far to a stable 1700mhz but i think i can squeak out a little more speed especially with the gpu down clocked a little. I run it at 1400MHZ Though with the gpu forced at 267mhz.
Hey fellow XDAers
I'm currently running LeeDroids awesome GSM Rom, with his Kernel and a lot of others the stock speeds are 384mhz - 1.51ghz (using LagFree governor).
I'm just wondering is there any point of having it boosted from 1.18ghz to 1.51ghz or is it just overkill? I can see the Sense UI is slightly smoother, but I'm not really sure how the battery life is affected by the OC.
If I wanted to save battery life, would it be best to reduce it back to 1.18ghz or use a different governor (and what one?)
Thanks in advance,
Louis
Gsm and cdma processors default speeds are different?

Yes i read overclocking do take a toll on ur battery just like an engine more horsepower/cylinder more gas lol if u really need the extra speed try juce defender or something to help save you your battery while over clocking. Hope this helps
I keep mine at 1.2ghz max as it is fast enough like that, and makes the battery last longer.
Yeah point off overclocking is that we don't need buy an new device to get some extra speed. But I think on 1.2 it runs fine to.
No sorry, I think I worded that incorrectly. I mean with custom Kernels they usually are 1.51ghz by default.

1.18ghz /10char
If you want insane speed is what you gain tho you don't gain better battery life More speed the less life... . Both cores running all the time will eat it up.
If you push it too high you can burn it up.. Depends on what you want outta things...
Well the second core isn't so active as far as I know. It has been more designed to jump in when needed.
But reason most custom roms include an overclock off 1.51Ghz is because the cpu was designed for it, HTC just under clocked it, but in the HTC Sensation XE they not underclocked it.

Ah, I see now. I get what you're saying now. Overclocking is good, but becomes detrimental when the freq starts sucking the life out the battery.
Aren't we underclocked from the jump. I though Chad Goodman said the actual processor speed is 1.5 by default. Per Qualcomm specs at least.

In short, yes.
OC'ing makes your phone much faster and, also helps out with benchmarks. However, battery saving is not an issue either. Most CPU control apps will allow you to set a different frequency when the phone is closed so it saves batter. For example, I'm on zr3d right now and my normal profile is 1.7x ghz. When the screen is off, it scales conservatively from 192 to 540 mhz. Gives better performance and better battery.

Lol That will save you life when your screen is off but not when your running a game or hammerin away at stuff
OC beyond Quallcoms spec 1.53ghz is pointless and good for nothing but killing your battery. There are a great many here who gush over high benchmarks but that means absolutely nothing in "real world" performance no matter how much they tell themselves that it does. Just sayin....
Thanks for all your reply's
But for the average use (browsing, video streaming, bit of gaming, messaging) what should I set as my max OC as? And what is the best governor for battery + performance.

Nope.jpeg. I was playing canabalt the other day at 1.5X ghz. It was the tiniest bit choppy so I upclocked to 1.7. Perfect performance and, also real world performance I believe(actually it's a game so its not real life).
Best settings I'd say would be 1.5 ghz on interactive/intellianthrax guvner while screenon and .5 or .3 ghz conservative/powersave while screen off. Or, for heavy stuff, go all the way up to 1.7/1.8 ghz.

Opinions from people who really know? I can't imagine that overclocking increases battery life.
It doesn't. At least from my understanding. In fact as I understand it running at higher clock speeds would decrease your battery life no? I usually under clock, so...

The theory is that overclocking allows you to complete processes quicker, which in turn allows the processor to go back to a idle/deep sleep faster. In practice it doesn't really work that way though.

doesn't the increase in voltage also come into effect?
They did talk a little about undervolting to increase battery life. Personally I don't worry about it. I'm not using my phone to sort out heavy algorithims at the moment, so running how it does is fast enough for what I use it at. Just found the article interesting.

They say the undervolting on lower clocks should balance out the higher voltage on overclocks.

Undervolting rarely makes a difference on mobile SoC's, but on the desktop/laptop CPUs you can really save a ton of power with undervolting and underclocking.
Why to overclock and understand it?
Here is a good reason to know what you are doing..
and the battery avg's lasting at least through the day, but most of the time, I have a charger near me...

The article says its not the actual overclocking that is saving battery life. When you put SetCPU on your phone not only can you overlock but you can underclock and set different voltages. I'm not 100% sure how the voltages play into it but you can set the processor to run at really low speeds during certain acts ei. when the screen is off, or any other time you don't necessarily need alot of power. That's and I changed all the voltages (I got them from a post where the guy knew what he was doing and tested them). I get almost 2 days moderate browsing, apps and text. If I talk alot or use my hotspot I only get 1.5 days. It is a little time consuming to get everything just right but when you do you really see it.

This isn't a SetCpu feature there are other programs that can do this as well. It just so happens SetCpu has it built into the program. I bought SetCpu back in my Atrix days and loved it so it does work great for a simple tuning program.

I'm running a kernerl and a custom ROM that allows me to underclock and overclock.
I tried it out both ways and the battery lasted for almost the same amount as on the stock option. As I tend to play games a lot on my phone, the underclocking ran into some issues with stuttering and sometimes force close of a couple of games.
Personally, I've never been a big fan of either .
