I'm curious as to which voltages people are using who choose to undervolt their device. I know I've seen some scattered posts around but am yet to see a thread, if I'm wrong feel free to close this one and direct me to the thread.
Mine are:
1200 mHz
1200 mV
1000 mHz
1100 mV
800 mHz
1000 mV
500 mHz
900 mV
200 mHz
900 mV
I made very small drops over stock as I'm pretty new to it so I didn't want to risk going to low.
I'm on UnNamed 2.2.1 with Entropy 12/08/2011 and CPU set to 1200-200 mHz on demand.
I'm trying to get an idea for what people run for the best mix of battery life and performance.
1700Mhz @ 1500mV
1400Mhz @ 1275mV
1200Mhz @ 1175mV
1000Mhz @ 1075mV
800Mhz @ 975mV
500Mhz @ 875mV
200Mhz @ 850mV
I havent done a whole lot of tweaking to find my optimal settings. Im hoping to have time to play with Zep's 3g turbocharger to see what i can squeeze out of my data with different modems. Im also about to move to UnNamed 2.2.1

I'm thinking I could go another -25mv across the board still.
There isn't a thread because you are supposed to figure out the settings yourself. EVERY DEVICE IS DIFFERENT. What works great for one person may crash another's device, what is just barely stable on one person's device may be far from optimal on another.
If every device were the same, THE STOCK VOLTAGES WOULD BE LOWER.
I was about to say the same thing ^^

These values provide a baseline for others to start from. I never guessed I could go down to 825mv until I saw another thread on the i9100 section. But I understand your point of view as well.

I tried undervolting even minimally and my phone crashes, regardless of the values
I'm perfectly willing to accept that I may have one of those unlucky devices that just can't handle it, however I just realized I've been mixing the too apps....could this potentially be causing CPU confusion, ultimately leading to crashes?

i would only recommend using 1 or the other.. (voltage app is best)
and -25ma across the board what do you mean?
1200
1120
1000
800
400
200
100?
your -25 on all of them?
cause if you read the threads supporting voltage app you will see to only change 5-7 profiles meaning...... dont do all of them... i keep only 4 of them under stock voltage.... as listed below (some phones cant handle the actual under volting NOT the over clocking.... and some cant do either)
1200: -25mv
1120: -25mv
1000: -25mv
800: -25mv
400: stock mv
200: stock mv
100: stock mv
i have been over clocking sense we got the kernels to do so... (i9000 kernels)
so if you need anymore help just pm me and i can help with a really good oc/uv set up or in your case just use setCPU its alot easier!
voltage app
which is the best governor for voltage app?
I had the same problem using both and thought it was my phone not liking oc with no uv but then I figured out by removing setcpu and only using voltage app that my phone was stable up to 1400. I have read many threads that state not to uv all freq's and not to use more than 5 states in the drawer. Also try to create the least voltage steps as possible and not to touch 800 cause thats where the phone us set to go to sleep and wake at which is critical. I think that set cpu and voltage asp conflict each other with scheduling, but I am not a dev so could not be sure.
Sent from my GT-I9000 using XDA App
I have used both. Set CPU sleep profile works beautifully paired with voltage control app.
Can someone post all available frequencies(the voltage for lower than 600MHz and how much battery will it take comparing to the lower frequencies, eg 864 takes "x" battery more than 844)
Is there safe to use 864, and does it take to much battery, or not?
Thanks a lot
Sent from my LG-P500 using XDA App
frequencies below 600: 122, 245, 320, 480 (all of these use the same voltage)
frequencies above 600: 652, 672, 691, 710, 729, 748, 768, 787, 806 (the difference in battery varies depending on your governor and usage but generally, the higher the frequency the more battery it eats)
stability-wise, the only thing that can go wrong when you oc to 864 is a kernel panic. other than that it should be safe to use. however, in the long run i think it can harm your cpu (and yes it does use a lot of battery)
this is my understanding. if someone does not agree, feel free to point out what you believe is wrong
yep sweetnsour is right ...
All that can be added to what sweetnsour said is that there are three more frequencies over 600: 825, 844 and 864 MHz. But the chances for our CPU to be stable at any frequency above 806 MHz are very low.
Another notable side-effect to the overclock, beside quick battery depleting, is CPU overheating. I found my CPU to be stable at 806, but I went back to 729 just because the phone warmed up so much faster. At 729, I sense no difference compared to 600 MHz.

This is highly subjective, no one can tell for sure, except maybe the manufacturer. Buy in theory you should be safe with any frequency at which your CPU is stable and does not overheat. You will sell or trash the phone long before the overclock will affect anything.
And remember: the CPU spends a fairly low amount of time at the high frequency; most of the time it will fall back to the minimum, as long as there are no tasks requiring high processing power.
As far as I could gather in the 10 months I spent on this forum, the community agreed that 729 MHz is the most convenient value.

I personally dont use Smartassv2 as it has some wakelock problems, so try different governors and find out which works best for you.

The hardware is the same.. However they phone is slightly different. Try 110% live oc and 1200 max step.. That's a pretty safe start.. If you crash try bumping init for 1000 and 1200 steps by the smallest amount i think it's quarter milivolt
Sent from my SCH-I500 using xda premium
Max freq: 800. (1000 effective)
Min: 100
Live oc range: 400-1000
Governor: conservative
Live oc: 24%
It's basically stock speeds with a 25% gpu boost on the higher steps. Conservative governor keeps it from crashing. ;-)
Sent from my SCH-I500 using xda premium
that doesnt crash your fascinate ?? as soon as i hit ok for 24% oc its an instant crash.
It will crash me on the 1000mhz step but not on the 800mhz step. Set 800 as max prior to setting the live oc. In fact, set everything else first and then set the live oc last.

Ya trying to copy other people's settings doesn't really work all the time, all our phones are different! Personally my stable settings are 1000Mhz with a 110% LiveOC - rock solid.
Most phones do 110% with no voltage tweaks, but not all. And remember with huge live oc you may need to bump arm voltages as well, specially on higher steps. Think about it, 120% your 1000mhz step becomes 1200. So logically use the default 1200mhz arm voltage for your 1000mhz step as a start.. This should be obvious. And stock voltages on init are medium or low leakage.
These are close to high leakage
100 1000
200 1050
400 1075
800 1100
1000 1125
1200 1150
These are what i use with 110% and 1200 max
Low target 800
High target 1500
I can go higher using just a little bit of common sense and some math.. I have had 125% but got about a reboot a day. But you need to use common sense in your arm voltages. Init are not quite as important

800 1200
400 1050
200 975
100 950 <---not that that one matters

1500 1200
1400 1175
1300 1175
1200 1175
1000 1150
800 1125
400 1125
200 1100
100 1000
This set up is more akin to a high leakage phone with a bit more voltage to compensate for the live OC.
Will def check this out. Thanks

Why do you want to raise the voltage? Usually you lower the voltage even when Overclocked, on mine it's OC'ed at 1.83 GHz and undervolted between -50 mV to -75 mV depending on the frequency steps. Any way, the hardware has a tendency to perform differently for each phone/user so you'll need to find what works well for your hardware.

If you run system tuner it starts with the default voltages, I beleive it's 1375mV at 1.89 GHz, 1350 at 1.83 GHz, with a 25 mV drop for each cpu down clock, I say "I beleive" because I haven't been at stock voltages or clocks for a long time.

Leave the speeds stock and undervolt. When undervolting don't ever check save for boot or whatever until you are certain those settings won't cause you problems. If you undervolt to low it will reboot your phone. Go to high and it could overheat but I doubt you will need to do that for any reason. I would start with a -50 uv and see if it is stable for a few hours. If you think its good -25 to all for a few more. I usually can't get below -75 across all voltages but every phone is different so some people can go -100.

Can I do this with setcpu?
Or would you recommend a different app?
Because when I started setcpu, it set me on 1036MHz max and 245MHz min. and the governor is set on lagfree, and then the scheduler is set on deadline.
Not really sure what to do here... lol.
Forgive me... like I said, I'm new to clocking.
I haven't touched anything since I started the app.. I was too concerned to.
It's not set on boot yet.
There's also a page for profiles and another for the governor... both of which are have me looking at them as if I were one of the three stooges looking at a supercomputer.

It's not giving me a 1024 max.
It jumps from 960000MHz to 1036800 MHz max. and then the min. is set to 245760MHz.
Next tab (SVS) has 850 in the box on the right all the way from 24576MHz to 245760MHz. Has 875 in the box beside 368640MHz, then 900 beside 768000MHz and so on.
Are you saying that in those small boxes on the right beside the xxx MHz I should lower that number by 50 all the way down to what I set the max to be?
Say from where it says 850 all the way from 24576MHz to 245760MHz, I should change that 850 to 800? And just -50 from every one all the way up the the MHz that I set as the max?
