Hi,anyone knows the best settings "setspu" for Samsung Galaxy Ace with Stock Rom?
Regards
setcpu won't work
over n out
what is setspu
dude read all the threads before asking..!!
theres already a thread in which we have discussed about this topic ..
and we dnt have any overclock kernel so no use of changing setting..!
and why u have to change setting...u can only reduce ur processor..!
Yup you could reduce clock speed if you want to save battery but it's not very stable.
Also the processor runs originally at 600 mhz but was overclocked by Samsung.

That's not true. The processor is designed to run at 800 by Qualcomm, as it is the newer "turbo" version of msm7227.
so, SetCPU does not working?! But why? I have SetCPU and i have the profiles:
ALL CHARGING: min 254 max 800 prior 100
Screen off: min 122 max 245 prior 78
Battery < 25%: min 245 max 480 prior 75
00:00 - 10:00 min 122 max 245 prior 70
Temp > 50.0 min 245 max 480 prior 100
Battery < 10% min 122 max 245 prior 61
This is optimal settings with "system logic", and now my cell working for a 2 day with much loading information and intensive using.
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

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.

1600: 1225mV
1500: 1175mV
1400: 1150mV
1300: 1125mV

0800: 875mV
0700: 837mV
0600: 825mV
0500: 812mV
0400: 750mV
0300: 750mV
0200: 750mV
0100: 750mV
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
1200 - 1100
1100 - 1050
1000 - 1000
900 - 950
800 - 900
700 - 875
600 - 862
500 - 850
400 - 850
300 - 825
200 - 720

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

I don't think he can use 400 MHz because there is no VPLL. I might be wrong tho...
Sent from my GT-I9100 using 1st ROM
My gpu isnt stable at 400mhz unless i use 1200mv. 330mhz is stable at 1150mv not 1100 for me
Also 100mhz my phone requires 950 if i have any lower i get strange artifacts on the screen sometime

VPLL mode adds 330, 440 and 520 MHz steps, so for 400 there is no need to use vpll.
