Compile your information like this, if we can get 50+ voltage tables from users we should have enough to create some decent starting voltages that should work for most people.
Being an insane computer geek, and overclocking my PC's like mad, I can tell you that your not all going to be able to use the same settings. Use these as a starting point if you wish, from what I have seen though, I have a great SoC for overclocking. I wouldn't expect to get those voltages with certainty. Phones are ridiculously easy to overclock though, the voltages adds a nice kick to the whole idea though. It's very easy to figure out what kind of overclock/voltage ratio your phone CPU has....
You can see it clearly in my table of voltages there. 1.0ghz and 800mhz seem to be the weakest, they require more voltage than any other high end frequency. So I knew that once I isolated those voltages I had an inkling where I would be in the end with all the other frequencies. Sure enough I couldn't get 1.0ghz to run -125mv. But it stopped there, 1.1,1.2 and 1.3ghz run @ -125mv. I suspect the voltage is already so high as it is you can adjust it a bit more. It only takes another 75mv to get to 1.1 and then another 100mv per 100mhz jump as per usual. Followed that all the way up and ended up with 1175mv for 1.3ghz and she's stable.
Going to let it run for awhile, best to get some results, and test them out real world for awhile. I would try -50mv first on all frequencies to start. I cannot see much chance of instability doing this.
1.3ghz = (-50mv)
1.2ghz = (-75mv)
1.1ghz = (-75mv)
1.0ghz = (-75mv) (-100 was definitely not stable and had lots of freezes/reboots)
800mhz = (-175mv)
456mhz = (-225mv)
216mhz = (-250mv)

I have only overclocked to 1.2ghz because I have no need for anything more and probably don't even need that sort of overclock. My undervolt settings are heavily tested for 1gz and down but barely tested above that.

Oh I totally left out the different tegraparts, nice reminder hehe. Looks like you have a really nice SoC there. Best one I have seen yet. Just tried your lower end settings for 456 and 216, no reboots yet.
I was trying to come up with a way to test each individual clockspeed. Came up with this.
Charge your phone up to 100% (gets her nice and hot) then set a profile for anything below 99% battery to lock at 216mhz, 456mhz, 800mhz, and so on. Then test using the stress test inside SetCPU, make sure to set your screen time out to "never" as well.
I am quite sure this will work. I will test and re post.
Can SOMEBODY PLEASE tell me how to overclock this phone? I've looked all over kingdom come for a tut but can't find anything except the 1.4GHz kernel module that doesn't even work. Help would be much appreciated

That 1.4ghz kernel never worked.
In order to overclock you need a kernel that supports it, there is one available in the dev section. Its made by faux.

Does nobody read the N00B Guide any more.
To clarify the -100mV thing..... does this -100mV range apply to reduction values or to the actual voltages all remaining within 100mV of eachother?

Not all phones will end up being able to handle the same undervolting or overclocking.
These are guidelines only and it looks like my phone is very capable of extreme undervolting down low. I actually think I'm going to back these off just a little bit even though my phone remains stable just for peace of mind.

Why is that?
And is there a way to check the current voltage?
There is a 100 mv limit between steps. I.e. from one step is -75 the next step can't be more than -175. But as I mentioned faux might've overcome that. If not, then your low end voltages are only 100 less than lowest voltage above that.

[Q] Best SetCPU Settings for CM7 with Bali
I am currently running CM7 with the Bali kernel. I just recently installed setCPU and wanted to know what the best settings are for having decent battery life without taking away to much from performance. I'm pretty new to OC/UV so any pointers would be greatly appreciated.
anybody? any help would be great? I've been trying to search for settings but havent gotten to far.

Here is my settings on Voltage Control for Glitch. That may help you out a bit. Have you tried looking in the Bali thread to see if anyone posted any stable results? 1300: 1400mv -0mv = 1400 1200: 1350mv -0mv = 1350 1000: 1250mv -25mv = 1225 800: 1200mv -50mv = 1150 400: 1050mv -75mv = 975 200: 950mv -75mv = 875 100: 950mv -100mv = 850
[Q] Undervolting Problem
Been Undervolting on the Glitch Kernel, and trying different things. What I have set my UV to is just slightly too low I guess, because it keeps restarting.. Have never really Uv'd before and having troubles finding the Lowest possible.. These are my Settings ; 1500mhz - 0 = 1500mv 1440mhz - 25 = 1450mv 1400mhz - 25 = 1425mv 1300mhz - 25 = 1375mv 1200mhz - 25 = 1325mv 1000mhz - 50 = 1200mv 800mhz - 50 = 1150mv 400mhz - 50 = 1000mv 200mhz - 75 = 875mv 100mhz - 125 = 825mv Any of this Look wrong? Any Suggestions?
I dont belive you should UVing the OC... just makes sense that anything over 1ghz should stay with factory voltage settings. Could be part of the problem your having?

Your best Undervolting Result!?
I was just wondering what type of undervolt score you guys are getting from your Exynos CPU. Mine isn't too bad actually 1600 - 1300mV 1400 - 1200mV 1200 - 1100mV 1000 - 1000mV 800 - 925mV 500 - 825mV 200 - 800mV The ROM and Kernel im using are in my Signature! I would undervolt my GPU as well but I'd prefer something like Tegrak app but suitable for other Kernels! Anyways the question is whats your score?
[Q][Stats]What is your lowest stable undervolt?
Hey fellow SGS3 users. Several kernels have undervoltage capabilities for the Galaxy S III. With this poll I'm trying to get a statistical handle on what the lowest possible voltages are on an average S3 device. I am currently running at -100mV on all levels and I'm wondering if some people have already spent time testing the limits of the UV that is stable for their device. I haven't tried anymore that -100mV but since I have been running stable on that setting for more than a day, I am considering to decrease the voltage even further. So if you're using a flat UV on all frequencies, fill in the poll and add any info you think may be relevant. If you use a specific voltage for each frequency, vote for custom and post your values (and maybe how you reached/tested them) So for me: Max Freq: 1.4Ghz Min Freq: 100 Undervolt: Flat -100mV Kernel: SiyahKernel S3-1.2.6 Edit: Seems stock voltages are not necessarily fixed on the SGS3 so take these with 2 grains of salt. Stock Voltages in Siyah (in mV): 1400Mhz - 1287.5 1300Mhz - 1250 1200Mhz - 1187.5 1100Mhz - 1137.5 1000Mhz - 1087.5 900Mhz - 1037.5 800Mhz - 987.5 700Mhz - 975 600Mhz - 962.5 500Mhz - 937.5 400Mhz - 925 300Mhz - 900 200Mhz - 900 100Mhz - 900
These ones work for me: 1400Mhz : 1100 mV 1300MHz : 1050 mV 1200MHz : 1000 mV 1100MHz : 975 mV 1000MHz : 925 mV 900MHz : 900 mV 800MHz : 875 mV 700MHz : 850 mV 600MHz : 825 mV 500MHz : 800 mV 400MHz : 775 mV 300MHz : 775 mV 200MHz : 750 mV
Max Freq: 1200 Min Freq: 100 Undervolt: -100mV Kernel: S3-1.2.6 the limit in ExTweaks is -100, i have Voltage Control Extreme but im not comfortable going any further for now
my uv values are in my sig, though -25mv from the one in my sig worked its not that stable .
Right now I'm running stable with: 1400: 1287500 > 1187500 = -100mV 1300: 1250000 > 1137500 = -112.5mV 1200: 1187500 > 1112500 = -75mV 1100: 1137500 > 1075000 = -62.5mV 1000: 1087500 > 987500 = -100mV 900: 1037500 > 937500 = -100mV 800: 987500 > 900000 = -87.5mV 700: 975000 > 837500 = -137.5mV 600: 962500 > 825000 = -137.5mV 500: 937500 > 812500 = -125mV 400: 925000 > 750000 = -175mV 300: 900000 >737500 = -162.5mV 200: 900000 > 687500 = -212.5mV Although I might still be able to get one or two steps out of the upper middle frequencies, I spent several hours testing trying to find my voltages and it is annoying and tedious work, and I stopped at the above values. My chip is being attributed ASV5, so middle ground in terms of quality of the chip.
I tried to do -50 on all steps using ExTweaks and Siyah Kernel.. and my headset speaker stops working Works fine stock, but as soon as I reboot after a UV I have no headset speaker :/

Fruktsallad said: How did you find your chip number and how do you know about its quality? Cheers! Click to expand... Click to collapse I'm curious about that as well. I find Kevin's values to be completely stable so far. I'm impressed with the UV potential on the SGS3. On the SGS2 I rarely managed to take 100mV off the stock voltage while Kevin's values are significantly lower than 100mV off the stock. I'll put the stock voltages in the OP to make comparison easier.

Its always those bottom 3 which I have as a screen off profile that worries me. I can ascertain the other frequencies by using the device, but these 3, the only real test is whether it falls over when Idle. Are any of today's kernels using AXI does anyone know? Not seen it mentioned in any of the threads.
I am at: GHZ mV 1.4 = 1100 1.3 = 1050 1.2 = 1000 1.1 = 975 1.0 = 925 0.9 = 900 0.8 = 875 0.7 = 850 0.6 = 825 0.5 = 800 0.4 = 775 0.3 = 775 0.2 = 750 I can't believe how far the s3 can under volt. I haven't had any problems with these voltages all day. I haven't and don't dare go any lower
Currently running these frequencies and everything is perfectly stable, no a single lockup or crash so far. Basically dropped all the frequencies by 100 mV then pushed 200mhz down as far as i dared as i figure undervolting is most useful for extending standby time. From other peoples settings it looks like I can lower most of these a lot more without any problems. Freq - mV 1500 - 1200 1400 - 1150 1300 - 1137 1200 - 1100 1100 - 1050 1000 - 1000 900 - 950 800 - 900 700 - 875 600 - 862 500 - 850 400 - 850 300 - 825 200 - 720

Seems that my UV is not stable and I had 2-3 SOD. This is what I did: undervolted the cpu step, then kept stuck the cpu on that step and tried for a while. I did this for every passage, and tested untill the phone freezed. So for exemple, I started from 900 mv, then went down 875-850 etc. If my phone dies on 825, I setup 850, or the previous valid voltage step. I did this for every cpu step, from 1400 to 200, but when I stopped keeping the cpu stuck on a single step and let it go between 200 and 1400, I started to have loads of reboots etc. Any hints? Since I've just spent like 2 hours of my life for nothing

Since I've just spent like 2 hours of my life for nothing Click to expand... Click to collapse I went through this same procedure and the same thing happened. Unstable as hell, wasted hours of time... I ended up just using extweaks to undervolt all clocks to -50mv by default and that seems to save me a decent amount of power. Also set sleep clock to 100mhz. Saves even more during sleep. Getting runs of 30 hours with moderate useage, browsing texting calling photos etc. Sent from my GT-I9300 using xda premium
I think the higher steps don't all undervolt quite as well as lower ones. To get 1.6 stable on mine needs quite a lot of juice and then it heats up a bit and benchmark scores drop so I guess there's some thermal throttling. I'll just keep it at 100-1400MHz 725-1200mv.
What app/program are you guys using to undervolt this? you wouldn't happen to be using setcpu right? This seems much more advanced than what setcpu offers?

Hello everybody. Just wondering if my Cpu downvolt has became in a performance improvement, especially in games. After downvolting cpu (gpu was already overvolted for overclocking to 400 mhz) I noticed an incredible improvement on games like nova 3 and asphalt 7. Could you tell my what are the stock cpu voltages for... 200mhz, 400mhz, 600mhz, 1000 mhz and 1200 mhz clocks? Thanks
