I have seen some talk about Voltage control in the dev thread and I am a little confused as to what it is they are doing. I do understand they are using the Voltage Control app and that you can set the min and max. When they start referring to under volting to 125 I am not seeing how they do that.
How are they setting it for 125? I have a feeling I am just looking at the surface and not seeing anything past that.

They minus (undervolt) each frequency by 125. It's in the Voltage section of the app. It will list the frequencies in there from 100-1200 or to 1600if the kernel supports it. So basically undervolting will use less battery when it hits those frequencies.

If you're going to try it, read up on it, you can have random reboots if set wrong. People say to stress test before leaving a setting.

Awesome! I thought it was something super simple I just wasnt putting 2 and 2 together so to speak. I am going to give it a whirl.
If you have tinkered with VC, what are the settings that have worked best for you?
I'm OC to 1.6, and UV's at -100 across the board, and running great!

It all depends per device. For example, my settings may not work well with your device. Really test it out first before you save the settings on boot. I'll link you the thread that explains it more.

Just wondering if anyone is using Set CPU now that we have root. I have it my phone but other than using auto settings im a little bit lost. Im just wondering if anyone has suggestions for the custom settings. Maybe some options for performance settings in particular. I want this thing to run like a rocket ship!

I dint seem to have much luck to be honest. considering the benchmark test somewhere on esato my marks were decent in the first 3 areas except for last area, FS, which ended up bad!!
I just got rid of alot of the in built apps and its running really smooth (4 now)
Sent from my X10i using XDA App
I made a profile with condition: screen off and max to 384 but, when the phone is locked, and I unlock it, it becomes laggy for a moment before getting the full 1ghz. I kinda didnt like it so changed the max to 576 and now it working properly.
But Im not sure whether its saving my battery juice or not ..
I cant remember where but i think in this forum there is another post about increasing bat life with setcpu. It has the profiles i was looking for. My phone seems to be working great with them. Im not at my pc but ill look later to see if i can find it and then post the link. Cheers

Bingo! That is it. My settings match these almost exactly, exception of my low bat is set to <20%, and my phone works great.

was poking around in the init scripts on stock system, and found that cpu scaling is already done in the stock environment

thank you wingz85 for link been lookin everywhere for settings guide
So I found a kernel on the Fascinate forums that was built off of our EC10 froyo source that was from nemesis2all and I saw that he had added the ability to overclock and undervolt from within the ROM so I installed it just trying (backed up of course) and found that it does indeed work.
I then got the Voltage control app from the market and started playing around doing Quadrant scores throughout after each change. I found that at 1200 mhz I was getting 1600s instead of 1400s and the phone ran great. But when I tried 1400 mhz the phone froze up and restarted while doing the CPU section of the Quadrant test so I reverted back.
My question is, what would be safe to stay at for general use?
Second question, how do you use the voltage app to undervolt I see the settings but I don't know what to set them too.
Here is the link to the kernel
1200 has proven to be the most stable overclock, any higher and it will freeze up eventually.
With voltage control, the way it works is that you set the max clock and then it will give you increments that the phone will automatically clock to within the guidelines you give it. Then for each increment you can set the voltage it will use. Just look around and experiment with voltages, see how low you can go without having issues and never set it to apply at boot unless you know that's what you want, other than that go crazy and a reboot will fix it if you have a problem.
I recommend keeping setCPU installed along with it, that way you can still force it to underclock or overclock or whatever. It all depends on how much you use the phone and what for.

H'm, I tried going up to 1.3 and it would freeze up after 5 or 10 minutes every time.
Like I said, 1.2 is the only one that has proven to be safe for everybody... not each phone is exactly the same and if akellars CPU has a soldering that is done a little bit different than mine, it might allow him to clock a little higher. who knows
Sent from my MIUI SCH-i500
I've been running it for a week @ 1400 -25 undervolted and haven't had any issues. The new 1.6 gives me trouble. I don't think there's enough overvolting in that one to make it stable for pretty much anyone. I use the 1400, 800, 400, 200 steps all undervolted @50 except 1400 which as mentioned is -25. Battery life is good because during sleep it doesnt really hit the high end and by not having the other steps its snappy when in use. Fastest this phone has been by far. I don't use setcpu because I think it and the voltage app conflict. That was nemisis's instruction to install it.

Yup I'm just lucky 1.4 worked for me too but I didn't see much of a performance difference so I didn't see the need to stress the cpu out anymore than I already was. battery life had been awesome for me with my setup as well.

SetCPU master coolbho3000 has updated his app to include support for the Tegra 2. It's available at all the familiar places.
2.2.0 - Added an "In Call" profile. Improved the Set on Boot safemode function by including a flashable zip that toggles SetCPU's safemode. Press menu on the main tab for more details. Added autodetect support for all Tegra 2 fakeShmoo kernels (ie. G2x). Added a "Voltage" tab for undervolting the CPU on fakeShmoo kernels, some custom Galaxy S kernels, and some Nexus S kernels. This is a full-fledged interface for undervolting these devices, and includes backing up and restoring and a Set on Boot checkbox. Improved the way SetCPU initially requests root. Various miscellaneous bugfixes.
Undervolting in SetCPU, now that's fantastic. By far the best purchase I've made on the market.

Also has a cool feature that allows you to extract a zip file to your sdcard in case you've set it to 1.5/1.5 and your phone freaks out. You can just boot into recovery, flash the zip and it resets setcpu.
I must say, SetCPU 2.20 is quite amazing... worth every penny
Note to ppl who upgraded from existing setcpu...re-detect your cpu speeds from the main screen. Otherwise, voltage tab will force close on you.
What would you set "in-call" to?

I have 400/400 for screen off. I set in call to slightly higher at 400/500.
I'll need to test it tomorrow during calls and see if the screen wakes up quicker after a call ends.
For benching, I set it at 1500/1500 at 1300mV with no profile set for maximum power, and I'm getting much lower benchmarks in Smartbench 2011, than I was with pimpmycpu. Why do you think that would be?

I did the same, but unfroze SETCPU and FROZE pimpmycpu.
In the transition, the battery got drained quite a bit over a few minutes, and heated up pretty fast when initially recharging. I had rebooted in between, but there may still have been some residual conflicts between the apps.
It froze at one point, but after a battery pull, it settled down. Overnight battery drain (with screen-off profile set pretty low) was only 4% over 8 hours. This is on EB 1.0.2 and faux stock kernel. Quadrent "only" around 4000, but everything works and this has apparently improved battery life.
A note on pimpmycpu - I thought scaling to min had stuck, but apparently not. Battery consumption was 12-15 % overnight compared to the above.
Thanks OP! I severely dislike pimpmycpu...

I have not seen that, although compared to Quadrent, I had not seen the very high scores that some had. I doubt SETCPU would impact you OC'd performance at max setting (although pimp had scheduler settings and SETCPU does not).
Could some give me a quick rundown on undervolting a kernel. I'm using faux's 0.4.2 oc/uv cm7 kernel. From my understanding its already undervolted but I'm confused about whether I should/can adjust those settings for better results or if I should leave them alone.
Info greatly appreciated.

Each chip is built differently, so you have to experiment on that yourself. That kernel may already be undervolted but it may not be right for you. I say adjust until you hit instability and then go from there.

Yes anytime you make you phone do something it didn't do from the factory there is a chance you could damage your device..its thx to all the great devs and people that test that make it easier and less likely also the more you read and understand what it is you are actually doing to the device helps alot!
If you have a kernel able to be overclocked/undervolted yes just use set CPU to adjust the settings.
All chips are different just cause a specific setting is working for someone else means it will work the same for you!
That being said I use:
Trigger 8/22 rom with faux123'a 0.4.2 kernel.
My settings:
Max-1408mhz
Min-389mhz
And have 1.1 GHz down to 389 mhz undervolted by 50 and no undervolt above 1.1
also have different profiles set for screen off and in call..
Good luck how this helps..

Thank you for such a detailed explanation! I'll be more weary of fooling around with settings. I'll probably set mine similar to yours.
Thanks everyone. I understood that setcpu would be used for the changes I was more wondering what the changes would do. Like undervolting by 50 for instance, what does that give as far as battery life? Im a moderate to heavy user and I only get roughly 8 hours off the charger before it needs to be back on, great signal all day too.
I suppose I'll just have to tinker with it till I get crashes then adjust from there.

How do u get the undervoltage adjustment? i have set cpu and when i try the voltage button on set cpu, i got forced closed. Thanks in advance.
Sounds like a bad install, try uninstalling setcpu then re-installing it or fix permissions in CWM or terminal
su
fix permissions
Used to have that issue too. Try the setcpu available here on the forums, I think that's the one the worked for me.

I guess you can consider this thread part survey and part for my knowledge so I know how far I can push this phone. I am at 1728MHz max with the interactive governor and cfq scheduler. Not sure if I'm going to do any undervolting, I can get through the day with about 40% remaining, and I have profiles set up for low battery and such. I am running CM10 with the 747 (I think that's what its called..) kernel and can push it to 2.1GHz. Is it stable at that high of a clockspeed? I can assume it turns your pretty Galaxy S3 into a convenient portable stove
By the way, sorry if this is the wrong section.

It really depends on your phone, I had mine at 2100 and it was stable. However it can very I had,a, Droid charge that ran the 1440 no problem, had it replaced and the new one could go above 1300 without hot boots. Some phones just hold up better

Stock. I've had it clocked to 1.9. But can't tell a difference with real day to day function except for worse battery drain and phone hotter.
Sent from a SYNERGIZED GalaxySIII
I have run the KT747 AOSP kernel at 2.1 ghz for a day or more and had no noticeable increase in heat, or decrease in battery life. (lulzactive or smartass v2 with either cfq or sio scheduler, no voltage changes in KT tweaker) I also saw very little or no gain in real world performance increase, and the benchmarking apps seemed to back that up. Typically run mine at 1.809 currently. Every phone cpu is different in terms of top speed, and voltage settings. Best thing to do, is to test them and see what works best for you. These 2 links, courtesy of the Ktoonez thread, provide some great info on kernel governor and scheduler settings. Given the number of options in KT Tweaker, these helped me a great deal in terms of making changes.
