Im using voltage control on ICS 4.0.3 Im not overclocked, anyone done any experimentation with the UV settings? Im wondering how low i can go without causing a reboot. Let me know what settings you are all using. If it helps Im using Nelsons new kernal. Thanks everyone!
I guess you could try the chart on glitch kernels thread.
Though it might be completely different since diff kernel but you can use it as a guideline
remember to check off set on boot when messing with voltages and only set on boot after you test for like a day without issue

Each vibrant cpu is different. Thats why some can overclock to 1.7 and others cant OC at all.
Back it off a bit and run it while a while - if its good try a little more.
As mentioned above, all vibrant are different so there is no copy/paste answer to this.
However, I will tell you what my settings are, and maybe they can serve as a starting point for your own experimentation.
1000 -50 (sometimes 25 depending on the rom/kernel)
800 -75
400 -125
200 -150
100 -175
Try different settings out, a day at a time...if you make it through a day with no freezes/ reboots....maybe try 25 lower. if you experience a freeze, try locating the problem setting and increasing it. Good luck

Thank you, a starting point is exactly what I was looking for. My phone does overclock to 1.4 without issue, but I never run it that high.

A couple weeks ago, I flashed the stock 2.3.6 rom using Mobile Odin Pro to retain root. Immediately afterward, I used CWM to flash Entropy's DD kernel. Then I did some undervolting with SetCPU. These are the voltages I have set right now:
1200 - 1175mv
1000 - 1100mv
800 - 1050mv
500 - 950mv
200 - 850mv
They're well within the suggested minimums from several threads.
Anyway, my phone has been freezing about once a day since then. It always happens the same way: the screen and capacitive buttons become unresponsive, and after a few seconds the phone reboots. Could the undervolting be causing it? Is there something else you guys can think of that might be causing it?
EDIT: Also, every time this happens, I lose quite a bit of battery charge. Like, if my battery was at 50% before the reboot, it'll be somewhere around 10% afterwards. Is that normal? I've attached a screenshot.

Have you set the voltages back to stock for a few days and seen if the freezing stops? That would be the first thing I would try Not all chips can handle the oc/uv

WHY DO YOU THINK THE DEVICE WASN'T SOLD WITH THESE VOLTAGES? What part of "every device is different" didn't you understand? What part of:
USE AT YOUR OWN RISK. DO NOT REPORT BUGS OR PROBLEMS IF YOU ARE OVERCLOCKING OR UNDERVOLTING. IF YOU EXPERIENCE ANY STABILITY PROBLEMS, DISABLE ALL OC/UV in BIG GIANT RED LETTERS in one of the first four posts of my kernel thread didn't you understand?
I have ZERO tolerance for someone who flashes **** and clearly didn't even bother reading ANY part of the thread.

Well if you would read a little (as entropy clearly stated) not all chips are the same, some can handle oc/uv and some can't. Seems like you are one of the ones that can't.

Wow, ok. I understood the risks to undervolting, and I realize I'll probably have to stop doing it. I was just hoping that this problem could be from some other cause so I wouldn't have to.
By the way, I read your entire thread, all 109 pages of it, before I flashed.
Sorry for being a noob guys. Go ahead and close this thread I guess.

I think we should make some stipulations that users cant download attachments until they hit 25 posts, that way they have been around long enough to know how to read and search.
So far I've just been using SetCPU for over/underclocking but have never messed with undervolting. I was wondering what most people use if your main priority is undervolting for better battery life. I'm running Siyah 2.6.7 with SHOstock ROM. Any help/feedback is appreciated.

Well, undervolting is very tricky. Each CPU differs in its ability to undervolt, so settings that work for one may not work for others. You'd have to do some testing. I recommend either a.) undervolting one tick and run AnTuTu benchmark multiple times as well as a demanding game/app (Run them for a long time), or b.) undervolting one tick and using your phone normally as per your current usage and if by the next morning it's still running as normal, repeat one tick.
Do NOT set "Set on Boot" to on until you've run these tests and have had no issues.
Hope this helps a little.
Do not worry about 1400,1600 mhz till later since that's when your overclocking.
Bump everything else down by 25mv, run the stress test and a few intensive programs like benchmarks/games.
Keep doing that till you start to notice problems and then revert to the best setting you had. (make sure to backup or not set on boot)
Once you go through all that then you can do it for individual mhz and see which can still be lowered.
This should keep you busy for a hour or so.
I'll share what I posted in another thread. Doing stress tests are fine, but if you test throughout the course of a day or more, you have the opportunity to come across situations you might not think of during testing.
Simba501 said:
Ouch....I think the best way to experiment with undervolting is to use Voltage Control. Save the stock settings as your boot settings (it saves everything - governor, frequencies, etc; so, make sure those are what you want them to be as well), then undervolt (at the beginning of the day). If you make it to the end of the day with typical usage, you can save those as your new boot settings. Undervolt further at the beginning of another day, etc. Once you make it to the point where you get locked up, voltage control will set the previous values at boot and you'll know that those are your limits.
EDIT: If you want to play it extra safe, run values for more than one day.

I'm at work right now trying not to get easily distracted by xda since I keep checking whether or not an ICS leak has been ported or something. Thanks guys for your much appreciated input. I've been running with all voltage values knocked down by 50mV with the exception of 1.4 and 1.6 GHz. Those I kept stock since I'm not overclocking. So far so good actually with sio/ondemand and Max 500 Mhz. It's surprisingly smooth and battery of course is doing exceptionally well at these settings. Switched over to voltage control for now.

I personally have become very fond of voltage control where as I'd previously been using set-cpu for nearly ever since the H1 and mytouch days. Voltage controls just allows more freedom and tweakability.

That's the post I was thinking of, I just honestly couldn't figure out where I saw it or who wrote it.
I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?
Just try clearing app data rebooting and reinstalling the app. That problem has happened to me every once in a blue moon and that fixed it for me.

Thanks, I'll try reinstalling the kernel.
Which app are you referring to? because I had this problem no matter which app I used to change the governor (Extweaks, voltage control, setcpu).

Hi Guys,
My first post here. I am total noob. I rooted and installed the newest ShoStock2 on my at&t galaxy s2. Everything works perfectly. I couldn't be happier. I also went bought the setCPU for overclocking it. That too seem to be working fine.
My question is. I didn't set up any voltage requirements. The only thing I did was to set it to 1600 MHZ and 200 min and change the governor on the bottom to Lulzcrative. Will this work? Do I need to actually do something with the voltage? am I really on 1600 right now? I cannot tell.
I ran a quad test (I now it is meaningless in real world) it came 2818 yesterday. I ran it again this morning ..... It froze and took my battery from 45 to 9 in less than 3 mins!!!!!! The phone got really hot. I took out the battery right of way. The battery life showed 23 percent this time.
I got little afraid of the quadrant testing ... The phone seems to run good without that but I am not sure if it is set up how it is suppose to.
Could someone help me out please? I tried reading the forums and that is where I got the idea in the first place to overclock it.
So to summarize it, I guess phone is fine right now but I am not sure if I set up setcpu out properly.
I am on the newest shostock2. I have galaxy s2 on att. I am pretty good with computers and phones but not sure about voltage and other problems with relating to setCPU.
Thank you advance for helping me out.

Lots of questions there. Phone overclocking is the same and at the same time different than PC overclocking. I too bought SetCPU and due to bugs and problems have completely abandoned it. Honestly with the exception of running an epeen benchmark there is little incentive to overclock. Find a newer Kernel (I use NEAK which has no overclocking ability) and install it, performance is stellar. You really have to ask yourself, is my phone slow enough that I need more CPU power to make it faster?
To see what time your CPU is spending at a given clock speed, download CPUSpyhttps://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&feature=nav_result#?t=W251bGwsMSwyLDNd, you will be surprised to see your phone spend very little time at it's max clockspeed.
Due to the immaturity of the fab process for our CPU's (well SoC), what is a stable overclock for one person might not even load for another. These CPU's are not like an Intel Sandy Bridge, with 1Ghz of free overclocking, nearly guaranteed. You can certainly play with voltages to try and attain a higher overclock, but at the expense of CPU lifetime, as well as battery.
Additionally, it takes a new Kernel 3 or so full charge, discharge cycles on a phone to really 'settle in' and 'learn' a particular phones battery, while yours got hot, which to me indicates an endless loop of some kind running in the background.
My advice would be as follows: Choose a ROM you like, feel free to play with different Kernels, again, I use NEAK, which does not work for some folks, or crashes or whatever. Give it several days to 'settle in' and if your still not happy with performance or have stability problems, try a different governor/scheduler. You really need to establish a good, solid baseline of your phones performance and make small changes and give them long enough to establish any changes to your phones overall stability. Basically running cowboy through your phone and making changes will have a negative overall outcome. Make small, documented changes, test and see what overall effect this has to your phone's stability and battery life, and make another change.

I'm just going off what I've seen in the Siyah/NEAK threads. Most of the lock-ups/random reboots I've heard people having had used the cleaning script. Either that or its just coincidence.
I may be wrong but I think that using the kernel cleaning script actually solved most of the lockups. Perhaps I misunderstood the threads.

Many have complained about issues with the kernel in ICS. On any build, it is vital that you not use setcpu or any other cpu scaling app. Don't change the max/min freq, don't change the governer, nothing. Perflock will constantly reset any changes and cause the cpu to run at either full throttle or full min - no in between. Until we get kernel source and custom kernels, this will always be the case. It's something HTC does.
Many cpu monitor apps will do the same. The link in my sig has more info, and a link to a cpu monitor app that is safe to use with our kernel.
Actually when I was on the second ics leak, and setcpu worked fine. I know this because I benchmarked before and after setting frequencies
Sent from my ADR6425LVW using XDA
benchmarking doesn't mean it wasn't running at full tilt when you didn't need it to. unless your kernel magically doesn't include perflock, it was.
also, there are some combinations of setcpu and monitoring that will work. at one point if i used setcpu, cpu monitor, and one other which i forget now, it would work, kind of. definitely not recommended.
Thats why I deaded mine. Phone was constantly overheating

since i stop fighting with the kernel i've had nothing but great battery life and performance since the first ICS leak.
tsp, what i don't understand is why something like system panel, which shows you scaling (but doesn't let you change it) showed the proper correct scaling between 384 and 1512 and hardly EVER hit full throttle on GB, but on ICS, it's always showing full throttle.
then i installed your widget you showed me, and it showed constantly chagning like system panel used to on GB.

Agreed. I had set CPU try to disable perflock and limit to 1200mhz on conservative and it ended up being worse battery and slower overall.
You're exactly right I advise everyone I discuss the topic with to make sure and avoid trying to over ride perflock with a CPU management app. It causes a conflict in my opinion which is a huge battery drain and also causes excessive heat due to the process of fighting for its life.

the widget i posted is what you want. it should be scaling up and down, and settling eventually when nothing is really going on. the system panel that you tried clearly affected the perflock in some way. from what i understand, some apps/widgets look at the cpu itself, while others hit up the kernel for status. the ones that hit up the kernel are the issue. i'm not 100% on this, that's just what i've been told. all i know is my experience seems to match this.

Hmm, that's weird, cause I've been using setCPU with ICS on the Rezound for months and it works great! My CPU scales fine and hits all the frequencies its supposed to. The min and max frequencies do change around seemingly randomly, but anyone can see by watching the current frequency display that it is always somewhere in between the range I selected, and always appropriate for the system load.
I've always had CPU Master installed. I just removed it, we'll see how it goes.

No offense but if you can't figure out a slider, perhaps you shouldn't be undervolting.
Besides, most devs don't believe it saves battery anyway. After stopping undervolting recently myself, I'm inclined to agree

Nah, I finally learned how to do it using System Tuner. I was confused because when I moved the slider a bit, all the numbers changed and I couldn't figure out where the -25 was gonna be at. But I got it now.
Are you sure it doesn't attribute to battery life? I went a whole -100mV in general and for me it seems to have improved a bit. Not by much but it is noticeable.
Anything else you recommend? I'm completely new to the device, but I familiarize with tweaking very quickly.

You mean better stability after or during the undervolting? And what's your stand on OC? Do you also think UC saves battery as well?
Lol sorry, I just like asking people that know about these things before I try messing with them.
Yeah its more stable at stock voltages.
I recently stopped overclocking. I don't have any particular reason not to overclock. I was troubleshooting an issue and overclocking and undervolting should be the first to go when doing this. Just didn't have a need to re-overclock.
One thing I would say though... if you're overclocking, don't add more voltage than 1400 MHz is set as stock... that adds heat. Heat + clock = damage

Yeah its more stable at stock voltages.
I recently stopped overclocking. I don't have any particular reason not to overclock. I was troubleshooting an issue and overclocking and undervolting should be the first to go when doing this. Just didn't have a need to re-overclock.

I see. Thank you very much for all this.
But I ran into a problem. Screen flickering. When the screen is off and I press the home button, a bright flash appears then the lock screen turns on. That's the only problem I've been having and it's scaring me like crazy. I've seen some flickering issues but none like this one. Do you think it has to do with the volting? I've restored normal voltages and hasn't happened so far. It's happened twice since last night and today. Both after undervoltage. I hope that was the cause.

No, it doesn't have anything to do with undervolting. It just happened again. I really can't tell what it is.
