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
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?

dragonmodz has undervolted the OC on his kernel i think so shouldnt matter but might do for some phones
Try 100mhz at 875 and if that doesn't work try 1225 on 1000mhz

Looks neat. I would try it but I am a complete noob at kernel clocking and voltage. Is there a guide for N1 volt changing?
I would give a try... looks nice GUI... emmm... does this same like SS4N1?

It's a lot of trial and error, you have to find the lowest voltages you can while still being stable and its different for all phones. Here is an example of a HAVS table that is stable on about 50% of dIncs (which share the same processor with the n1, so I'm guessing your voltages may be similar)
128000 850 875
245000 850 875
384000 875 900
422400 875 950

You can use these as a starting point. They may or may not be stable for you. If you're running an SVS kernel (only one set of voltages comes up when you start the app, use the voltages on the right of the table.

I'm unfamiliar with ss4n1, but this is an app that is used to adjust cpu voltages so that you may under or overvolt the cpu.

I'm new to undervolting background. I remember reading about havs before but forget most of what it is. .. . . .can I ask when setting the voltages what is the correspondance of havs voltage to normal voltage? It appears to be higher by most ppl, is there a set amount which it should be higher than original undervolt per frequency?

Most generally set the voltages lower than whatever undervolt is provided by the kernel. It takes a lot of trial and error to get the voltages as low as possible while still being stable. If you look above I posted an example table that you may use as a starting guide.

Thanks. I just realised my kernal doesn't support havs so its tab/settings are irrelvant anyway XD But I used your table but then found another table in a thread for a kernal for my phone with voltages much lower again and I adopted those values without any stability problems so far
EDiT:My second question has been answeres . .read changelog now that I kno I can restore my custom Voltage table through titanium backup this is now one my my favourite utilities
Wait . . .just realised that 'set on boot' isn't working for me :/
When I apply changes and click set on boot and restart my changes are lost and voltages are back to default! it does say 'boot settings found' though
And another question on a related note, let's say voltage at 122 is 800mv. . . .and voltage at 192 is also 800mv. Does this mean the battery drainage of running at 122 and 192 is identical?
(Because if this is the case it would mean by always setting the minumun frequencies at the highest voltage of a certain mv range you get the same battery drain but tasks get done faster so its being drained for less time . . .saving battery?)

Are you clicking set on boot and then clicking apply afterwards? You must check the box and then click apply. Try restoring defaults and trying again.
Also, a higher frequency running at the same voltage will draw more power than a lower frequency at the same voltage. While the voltage is the same, the current draw at a higher frequency is more = more drain.

Looks like the kernel dev made those frequencies usable. If you utilize them then you can adjust the voltages. If you don't use them then you can leave them. What kernel?

Ah ok, in that case because the frequency is so much lower I should be able to put the voltage wayyyy down am I right? Its already undervolted by about -50)

In theory you should be able to go pretty low on them. But it only matters if you actually use those frequencies. What is your minimum frequency set at?

Well I'm not using them atm because I was afraid they would cause instability on wake mode and in sleep mode I taught they would keep the phone out of om state for longer than what was worth the battery saving.
At the moment the minimum frequency for both screen on and screen on is 122880 @775mv
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 :/

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.

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:

1.4 = 1100
1.3 = 1050

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.

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?

Hi,
I make this thread like there is one for the Qualcomm S600 in the HTC One forum for example, or Nexus 4, Galaxy SIV, etc... (explanation here).
Turbotab said:
Each SoC Qualcomm produces is tested (binned), the closer it comes to the ideal the better, these superior chips are described as higher binned. A higher binned chip will requires less voltage, to achieve a certain frequency than a lower performing part.
This means that the 'superior' chips can be overclocked further or undervolted more aggressively, so this info is important for overclockers / modders.

You can see the binning of your SoC in the last_kmsg located in /proc/last_kmsg.
You can also found it in /sys/devices/system/soc0 and search for pvs_bin and speed_bin or /d/acpuclk.
It's the easiest method for me.
EDIT: can be found also from the hidden menu:

Settings-> version info under PVS bin.
Mine is:
pvs_bin 2
speed_bin 1
We can have pvs_bin 0/1/2/3/4/5/6 or slow/nominal/fast (it's the same thing but I don't know if, for example, slow correspond to 0, 1 or 2... ) for ours SoC if I'm not wrong.
My stock voltage:
CPU_KHz VDD_Core
300000 -> 775000
422400 -> 775000
652800 -> 795000

In this thread you can post your pvs_bin and speed_bin with your voltage table if different than mine to see the different binning of ours SoC.
The stock voltage table is located in /d/acpuclk/acpu_table (VDD_Core).
This can help for undervolt.
You can also check it in the service menu in settings-version info

300000 -> 800000
422400 -> 800000
652800 -> 810000
729600 -> 820000
883200 -> 840000
960000 -> 850000
1036800 -> 860000
1190400 -> 885000
1267200 -> 895000
1497600 -> 930000
1574400 -> 945000
1728000 -> 975000
1958400 -> 102000
2265600 -> 1075000
Pretty interesting that there are differences in retail devices.

Hi,
Ha ha LOL, I didn't know that you could see it in this menu (I used it to the "High Temperature Property Off")
Thanks for the tip

:good:
Yes, a pvs_bin 4 , thanks
We can compare the voltage between pvs_bin 1 and pvs_bin 4, -75mV... not too much.
For me it's the first time I have a Qualcomm SoC with such a low pvs_bin . But in any case I do not play too much with undervolt, so...

Hi,
Read te OP the quote from Turbotab... This is mainly for undervolt.

yes better cpu i meant..better undervolt and at stock it needs less energy
Screw you all - PVS 0 here, speed 1

I also can't go <800mV. It reverts back after reboot.

Mine is 1 and 1 also.But Snapdragon SOCs are hot as they are already,let alone overclocking them.Undervolt tho will be nice.Is there a program to change the volts without a modified kernel?

Hi,
Nope, you need a custom kernel that allows undervolting... After that you can use an app like Trickster Mod to undervolt. Without a custom kernel it's not possible, the ability to undervolt is "hardcoded" in the kernel and it's not possible with the stock kernel.
mine is the same as OP:
pvs_bin 2
speed_bin 1
D802 International, Software ver. D802b
4/1 here voltage take same as others with 4/1

Also got 2, but using the custom kernel by wootever here on XDA I can easily reach 975000 for 2265600, and all frequencies lowered by that difference accordingly.

Do you notice lower temps while gaming??
