So, I managed to undervolt my s3 to the point that I'm scared to do it further (freqs 1600-900 are final, 800MHz-200 still open). This settings are fully stable (2 days no reboots...yet). I was desperate to lower my batt temperature due to thermal throttling in order to play some heavy game on emulator, and well - didn't expect such results!

Guys, if you managed to go achieve similar results post it along with your chips' ASV level, the other threads seem dead

tegrak promised he was going to upgrade his tegrak overclock app to work with all kernels and it looks like he's delivered! (see http://forum.xda-developers.com/showthread.php?t=1101355
I'd installed the free version as tegrak suggested a couple months back to see if it would work with my phone. It didn't, but yesterday, it upgraded to version 0.6.0.9. I had a bullet kernel that allows OC to 1.2 ghz with no voltage adjustments. The free version doesn't OC but will let you know if the paid version will work with your phone.
The paid version ($2) works. At least on my phone it does. Maybe no need for special kernels anymore. I haven't tried it with a rom that doesn't support OCing and overvolting yet but I'm going to do that this weekend.
The higher speeds need overvolting and there's no directions on how to do it. tegrak overclock will officially only let you go to 1.3 ghz but if you select the fine "optimization" you can go way up beyond that. I immediately zoomed it up to 1600 mhz with no voltage adjustments and the phone locked up and started buzzing. I had to pull the battery and reboot. Don't do that! Go up a little at a time and then let the stability test run (pull down notification screen to see how many seconds are left.)
There are buttons to adjust by small amounts. You should be able to set it at 1.4 ghz with a little overvolting without too much trouble. Right now my phone is stable at 1524 mhz and core voltage of 1361 mv using an "on demand" profile of 100-1524mhz and it's not hot. Quadrant score at that setting was 3201. That's pretty good for a kernel that only supports OC to 1200 mhz.
I couldn't get to 1600 yet without locking up the phone -- needs more overvolting I figure.
If you have sgs overclock, after you up the speed, it will have the top speed bar at the bottom 100mhz and you will have to drag it up there. I don't know why this should make a difference but my quadrant score was in the 2700s before I did it.
Write down your figures 'cause if the phone locks up and you have to pull battery and reboot, the phone will ask you if you really want that speed that didn't work, and when you say "no" you'll be back at the beginning again.
There is more discussion in the 19000 forum on tegrak's 2.3.4 kernel (for I9000) and the OC app. according to tegrak's guide, the Galaxy S can be stably undervolted using his utility at various speeds and I guess save battery life:
speed standard core voltage undervolt
1000mhz 1275 mv 1225 mv
800mhz 1200 mv 1125 mv
400mhz 1050mv 950mv
200mhz 950mv 825mv
100mhz 950mv 800mv
There is a dialog in the app to set the voltage for each of these speeds in addition to setting the OC speed and voltage. I'm not sure whether tegrak has tested this on the various flavors of Galaxy S or whether he means the I9000. I'll just have to see.
here is his figure for a 1200mhz OC.
speed standard core voltage overvolt
1200mhz 1275 1310
Seems to be working good!

After some research, I've chosen to run -50 up to 1,000Mhz.
I've ran V.11 HL at -50 from 100 to 1000 with NO problems. Then I tried ML at -50 across the board with no problems and now I'm running LL at -50.
My question is whether anyone has compiled user settings into one location to find patterns. That is, does 100Mhz generally perform better at -25 or -250mv? How about 200, or 400...?
Has this been attempted?
My hope is to find a trend to aide in finding the 'best' settings based on many users.
ML Settings
I'll start.
Now running:

Phone did some funny things when attempting to fix brightness to high while outside. This was while using the above settings on the Low Leak platform. I am now reverting back to the High Leak to play around some more.
I've run -25 from 100-1,000Mhz for nearly 24hours without any problems.
Here's what I've had setup for a few weeks and I have zero problems whatsoever. Using Medium Leakage.

I would like to know what kind of battery life everyone's getting. With light use, my phone drains 5% an hour.
The new glitch 12 has some recommended setting in the op.

dblash,
From MIUI 1.8.26 to 1.9.16; from using Glitch to non Glitch, I average about 18 hours of battery life under 'normal' use. normal should be understood as about 30-45min heavy usage in the morning, about 15min over lunch, and about 1hr of heavy use in the evening. My screen brightness is usually set to full brightness too.
My settings are
1.4GHz / -50mV
1.3GHz / -50mV
1.2GHz / -50mV
1.0GHz / -50mV
800MHz / -75mV
400MHz / 75mV
200MHz / 100mV

Keep having little Glitches with the Newest Glitch kernel. Decided to remove it and troubles go away. I'm currently running stock (MIUI 1.9.16) settings without any kernel
What are the glitches your having?

pretty similar to this voltages, too lazy to type it out.

Most recent glitch was Google+ fc-ing 4 times when trying to type. Reflashed MIUI and fc goes away. There were several less critical issues as well.

Glitch updated last night and fixed all of the lag issues, things are working much much better now.
I was just wondering what type of undervolt score you guys are getting from your Exynos CPU. Mine isn't too bad actually
1600 - 1300mV
1400 - 1200mV
1200 - 1100mV
1000 - 1000mV
800 - 925mV
500 - 825mV
200 - 800mV
The ROM and Kernel im using are in my Signature!
I would undervolt my GPU as well but I'd prefer something like Tegrak app but suitable for other Kernels!
Anyways the question is whats your score?
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

Undervolting cpu means less performance? I Undervolted with a option from my kernel. Seems to get same quadrant score. Shoild i do other tests? Is it ok? I Undervolted just 25mv. I want good performance and good battery. Already removed a bunch of após with alot of wake up and wavelock. It Seems its much better

Undervolting results are fairly different because it depends on the usage.. if your.phone get lags or random shut downs or random reboots, then your phone cannot handle the UV.. but as what you have described, your phone seems fine

Undervolting doesn't effect performance, underclocking does.
However as already pointed out if you undervolt too much your phone can freeze or reboot.
25mv undervolting is fine

Undervolting can be hit and miss. You just have to spend time tweaking and testing and find the best values for each frequency
I use an app called voltage control it's a great tool.

I have been uv many times on different kernels. Still can't say if that really save more juice. You know, in theory it does. But there are plenty of other things that do. Starting from less brightness and being carefull what apps you install... I recommend GSam Battery Monitor to watch them.
How about gpu? Is bad to undervolt? Thanks again

Ehhh. Don't Undervolt GPU. You will get constant freezes especially when you are playing games.
However Undervolting CPU by 25-50mv is fine.
Kernel configuration was:
200 Mhz - 950mV
300 Mhz - 975mV
400 Mhz - 975mV
500 Mhz - 975mV
600 Mhz - 1000mV
700 Mhz - 1025mV
800 Mhz - 1075mV
900 Mhz - 1125mV
1000 Mhz - 1200mV
1100 Mhz - 1250mV
1200 Mhz - 1300mV
Made a Manual configuration:
200 Mhz - 875mV
300 Mhz - 900mV
400 Mhz - 925mV
500 Mhz - 925mV
600 Mhz - 950mV
700 Mhz - 975mV
800 Mhz - 1025mV
900 Mhz - 1075mV
1000 Mhz - 1175mV
1100 Mhz - 1200mV
1200 Mhz - 1250mV
Seemed to be stable this way. On 1000 Mhz i couldnt undervolt -50 for some reason, gave imediate freeze. I've made 30 secound stress test on each frequency. Seems to be working fine
