I recently installed teamhacksung's ICS Build 15 with Glitch v14b1 kernel and noticed that you can't undervolt like you did in cm7/gb anymore but also can undervolt the internal voltage. I took me some time but now I think I got some good undervolt settings, which I want to share with you:
arm voltage (in mhz)
100: 775 mV
200: 800 mV
400: 950 mV
800: 1125 mV
1000: 1225 mV
1152: 1300 mV
int voltage (also in mhz)
100: 975 mV
200: 1050 mV
400: 1050 mV
800: 1050 mV
1000: 1075 mV
1152: 1100 mV
this ones are working good for me. hope I could help you.

i guess so. if the kernel's for cm9 and onecosmics build also work with it you should give it a try.

yap... i tried it on drzMIUIv4 rom...
its work & stable...
like to ask, if we undervolt the voltage, can we increase our battery life ?
i tried ur setting, but my battery life still same with stock voltage...
3G mode : less than 8 hours on moderate use
Thanks for the information and I will give it a try.
Phone restarts........ may be this is not for me....... by the way...... how is its effect in battery backup ?
Thank you for your information ^^
Will try it tonight
Hi @all,
everyone is invited to post
1. ROM
2. Kernel
3. Kernel settings
4. UV settings
independently of ROM or Kernel used.
It might be a good starting point to compare other user´s experience.
Before using the settings postet in this thread please keep in mind that each device is different. Good settings for device A might produce freezes on device B.
So share your and enjoy other´s experience´s ...
here are my stable settings:
ROM: CheckROM RevoHD v6
Kernel: N.E.A.K. 1.4x
CPU Gorvernor: conservative (with all tweaks over CWM recovery enabled)
I/O Sched: sio
200 Mhz - 1200 Mhz
Voltages:
100 Mhz - 850 mV (... can´t go lower for testing with voltage control )
200 Mhz - 850 mV (... can´t go lower for testing with voltage control )
500 Mhz - 875 mV
800 Mhz - 975 mV
1000 Mhz - 1075 mV
1200 Mhz - 1175 mv
GPU settings:
Low: 133 Mhz - 800 mV
High: 133 Mhz - 800 mV
I am not a gamer and this settings are solid stable for my device. I use the phone mainly for (heavy) phone call´s (I know its old fashion ) and @home for surfing via WIFI. I enable my mobile data connection only when I need it.
This setting´s give me 3 - 4 days battery life.
I use lulzactive governor and vr I/O sched before and I feel NO difference in performance compared with the above settings (regarding scrolling through menus, starting apps ...), but the above settings gives me better battery.
Regards
Antonio
Update: I have to mention that I have the 2000 mAh Samsung battery.
OROM: Stock 2.3.5
Kernel: N.E.A.K 1.3.3.x
Voltage controls: All default.
100-800mhz
Lulzactive, VR
I usually get 1 & a half days battery, with an average of 7 hours screen time. The phone still runs beautifully while playing games and such so I have no problems in that category.
Edit:
Wifi on 80% of the time, a few hours of XDA. Skype on 100% while wifi is on. A few hours of games (dolphin, mc3, cut the rope, etc.), hours of Internet browsing, etc.

A last note:
Posting your settings and your battery charge cycle, please also mention the way you using your phone during the day to make your post more comparable ...
have fun

My battery last 2 days with push Exchange connectivity, gmail pushing too, some gaming (no more than 1h x day), 1h voice calls x day, normal texting activity (30-50 daily text messages) and automatic brightness customized to be darker than default.
Battery last longer if you do not let fully discharge it (plug it at night if you can, no matter the charge left).
@Floodland
I usually don´t let the battery go down below 15% - 20%, then I start a new charge ... I break this rule only in case on an emergency when no charger is near by me
I´ll try your 1000 MHz and 1200 MHz voltage setting´s, will post back if they work on my phone

New voltages ...
Hi @all,
here are my settings after new tests. The stability was testet by three sequential cycles of the N.E.A.K tester in each (fix) frequency:
100 Mhz - 850 mV
200 Mhz - 850 mV
500 Mhz - 850 mV
800 Mhz - 950 mV
1000 Mhz - 1050 mV
1200 Mhz - 1150 mv
Will test in next bettery cycle if they are stable in daily use, and report. Fell quite secure cause i´m not a heavy user...
Will test the settings starting tomorrow with the new N.E.A.K 1.4.1x kernel (simone told in his thread that the kernel should be released this afternoon).

normally working from 100mhz-800mhz.
i managed to get lower mv for the cpu and stable but it was the limit. so i added 25mv more for more stable results.
Who dares trying my extreme UV values ?
My UV stable table (Mhz/mA) :

Works perfect for me. Always heavy usage and get nearly 24hours with standard battery. Screen on time 4 hours. With siyah I had nearly the half of the uptime.
Wifi always on. Sync on. I mean this is what it was made for

Hello there,
many threads here in General and in QA,are asking about the best ROM,the best Kernel,or the best combo to get the highest performance and a lag free experience,i was also trying of finding the best combination,but i decided to do it the hard way,i started flashing and flashing,tweaking kernel settings trying to achieve the greatest performance.
at the end i achieved a combo that's making my nexus s run super smoothly with full trebuchet animations and good game experience (running N.O.V.A 3 without any lag ) anyway here is what i tried,it's pretty stable with me and offer a great performance (though battery isn't that good well that's the price of performance)

KERNEL
Matr1x BFS

and a big thank for the great devs offering us all those roms and kernels really thank you for your hard work
Hi all,
I've made a video about undervolting following the guide that omniwolf made.
It's nothing more than me talking (too much) about it and actually doing it, I'm really not adding anything to the guide itself besides the fact that you can watch me making a fool of myself, think that if I can do it, anybody can... So it's more an encouragement than anything else
The voltages I got are:
100 MHz - 675 mV
200 MHz - 700 mV
300 MHz - 725 mV
400 MHz - 750 mV
500 MHz - 800 mV
600 MHz - 825 mV
700 MHz - 850 mV
800 MHz - 900 mV
900 MHz - 925 mV
1000 MHz - 950 mV
1.1 GHz - 950 mV
1.2 GHz - 950 mV
1.3 GHz - 1000 mV
1.4 GHz - 1050 mV
1.5 GHz - 1075 mV
1.6 GHz - 1150 mV
Please don't just copy them, every CPU is different and they may not work for you. I also raised them all by 25 mV to avoid instabilities.
I don't have results and probably I will never have them... So I can't actually tell how much this affects battery life and temperature. I'm not convinced it makes a lot of sense to undervolt a tablet, since the screen is pretty much going to be the main drainer anyway, that's why I'm not focusing on collecting data to support the usefulness of the process
Did anyone else try undervolting the Note 8 (old thread about it here)? Also I'd be glad to hear the opinion of someone who's more qualified than me (basically anybody) about the subject in general and about undervolting this specific device
Cheers
Hi,
I have used Tegrak Overclock Ultimate to overclock my Galaxy Note 1 (N7000) at stock kernel. It works with Cyanogenmod11 (Kitkat 4.4.4.). This are my settings:
1748 mhz: 1500 mV - 1300 mV (+200 mV) (stock is 1400 mhz)
1200 mhz: 1100 mV - 1275 mV(-175 mV)
1000 mhz: 1000 mV - 1175 mV (-175 mV)
800 mhz: 950 mV - 1100 mV (-150 mV)
500 mhz: 900 mV - 1000 mV (-100 mV)
200 mhz: 850 mV - 975 mV (-125 mV)
I have also underclocked my GPU, but I don't remember the stock voltages:
267 mhz: 900 mV -
160 mhz: 850 mV -
134 mhz: 850 mV -
I hope this could help you!
