I have tested and submit score with an tutu benchmark and I saw a venue phone which has cpu frequency was 1190 MHZ but I don't know whose was it.
Who had this rom...please share it ...
my total score is 2528
cpu frequency: 998mhz

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 :/

How did you find your chip number and how do you know about its quality? Cheers!

A stupid and simple way to do it is to check your default voltages and compare them to the ASV table.

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.

This was a good starting point to get rid of my -100 blanket UV, but using that as a firm base.

Seems stable so far. 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

How did you work out your setup?
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

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.

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?

I use setCPU. All we are doing is setting a voltage for each clock frequency. Set CPU has a voltages tab.
doi its fine

thanks for the reply and screenshot, what version are you using of setcpu? i don't seem to have the voltages tab there.. My only tabs are: Main|Profiles|Governor|Info|About.
maybe i'll see if I can update my version maybe...
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

Undervolting cpu means less performance? I Undervolted with a option from my kernel. Seems to get same quadrant score. Shoild i do other tests? Is it ok? I Undervolted just 25mv. I want good performance and good battery. Already removed a bunch of após with alot of wake up and wavelock. It Seems its much better

Undervolting results are fairly different because it depends on the usage.. if your.phone get lags or random shut downs or random reboots, then your phone cannot handle the UV.. but as what you have described, your phone seems fine

Undervolting doesn't effect performance, underclocking does.
However as already pointed out if you undervolt too much your phone can freeze or reboot.
25mv undervolting is fine

Undervolting can be hit and miss. You just have to spend time tweaking and testing and find the best values for each frequency
I use an app called voltage control it's a great tool.

I have been uv many times on different kernels. Still can't say if that really save more juice. You know, in theory it does. But there are plenty of other things that do. Starting from less brightness and being carefull what apps you install... I recommend GSam Battery Monitor to watch them.
How about gpu? Is bad to undervolt? Thanks again

Ehhh. Don't Undervolt GPU. You will get constant freezes especially when you are playing games.
However Undervolting CPU by 25-50mv is fine.
Kernel configuration was:
200 Mhz - 950mV
300 Mhz - 975mV
400 Mhz - 975mV
500 Mhz - 975mV
600 Mhz - 1000mV
700 Mhz - 1025mV
800 Mhz - 1075mV
900 Mhz - 1125mV
1000 Mhz - 1200mV
1100 Mhz - 1250mV
1200 Mhz - 1300mV
Made a Manual configuration:
200 Mhz - 875mV
300 Mhz - 900mV
400 Mhz - 925mV
500 Mhz - 925mV
600 Mhz - 950mV
700 Mhz - 975mV
800 Mhz - 1025mV
900 Mhz - 1075mV
1000 Mhz - 1175mV
1100 Mhz - 1200mV
1200 Mhz - 1250mV
Seemed to be stable this way. On 1000 Mhz i couldnt undervolt -50 for some reason, gave imediate freeze. I've made 30 secound stress test on each frequency. Seems to be working fine

Good post, very best working on 5.1.1 dity unicorns
Hi there XDA Community! I'm new here ... but readed some topics. I hope this is in the right category.
I first want to say thanks for al devs and for their Tutorials, Kernels, Roms, Themes, Scripts and others
So, I made this post for anyone who would want to do OC to his Xperia Mini ST15i ( Smultron ).
I have here some results, with details ... but a question too.
Kernel: Panic Kernel with addons + 3D JB Adreno Drivers
ROM: HyperbeamCream 3.0 + Some Pimp My Rom tweaks
I did some benchmarks with different OCs... but also with different Kernel and... actually ... ROM:
Kernel: Mini Kernel that came with Ginger Extreme ( I think ... EDIT: I think it was Rage Kernel ... but not sure ) ... Which support OC at Max 2GHZ and Voltage settings ( Now, I thinks this is a must )
ROM: GingerExtreme ( Tweaked with Pimp My Rom and Supremacy Script v3 )
1200 mAh
1017 Mhz ~ near 1400 Score in AnTuTu Benchmark ( Only CPU and RAM )
RAM: 362 points
CPU Integer: 732 points
CPU float-points: 322 points
1200 mAh
1113 Mhz
RAM: 380 points
CPU Integer: 781 points
CPU float-points: 339 points
1200 mAh
1209 Mhz
RAM: 413 points
CPU Integer: 864 points
CPU float-points: 374 points
1200 mAh
1305 Mhz
RAM: 456 points
CPU Integer: 918 points
CPU float-points: 400 points
1200 mAh
1401 Mhz
RAM: 483 points
CPU Integer: 969 points
CPU float-points: 429 points
1250 mAh ( Don't know why ... even if I modified the value, it still was stuck at 1250 )
1516 Mhz ~ Over 2000 points in AnTuTu Benchmark ( Onlu CPU and RAM )
RAM: 512 points
CPU Integer: 1064 points
CPU float-points: 437
Now, I also did some OC with this ROM and Kernel ... was different ( in some ways .. but, at 1.6 Ghz I got scared... in 3D Benchmark the screen got a green color ... :-? , still, no damage on my phone, and I think it wasn't overheated ... )
Panic Kernel + HyperbeamCream ( as said at begin )
???? mAh
1401 Mhz
RAM: 526 points
CPU Integer: 1030 points
CPU float-points: 437 points
Also got near 83 FPS in 2D Graphics and 60 FPS in 3D
Then ... after the problem with 3D Test ( Now I think it was a misunderstanding but still ... )
???? mAh
1612 Mhz - 2197 AnTuTu Score ( Only CPU and RAM )
RAM:574 points
CPU Integer: 1137 points
CPU float-points: 486 points
Now ... Got some questions ... I think my battery is 1200 mAh ... it would cause damage to run an OC with more than 1200 mAh? I'm not sure about this ...
Anyone Knows there an ICS ROM that support voltage modification ?
I searched on Google, Youtube, XDA, and Didn't found very much documentation on Xperia Mini ST15i Overclocking ... so I'm posting these here for anyone interested ... even, a general topic about that, would be good.
Also played NFS Most Wanted 2 on my 1.5 OC GingerExtreme, it was running very smooth ... I think it had around 30 FPS ... even when I was near opponents, the FPS didn't drop!
