Would this cause CPU freezing/crashing
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 doubt it I use both of tgem and nithing crashed maybe you phone cant handle overclock or ur settings try lowering them

ive tried as low as -25 across the board....it usually rides well for a while....but eventually leads 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.

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.

Yes a rooted with other tuning needs no oc, but what is thr highest that will not harm anything on a long term...
And does 122-480MHz really have same voltage?

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.
Btw, you are using the wrong kernel for your rom(6.5.8), you should be using fserve kernel or 4 Sept kernel by Franco (.32).
Yaa 480--729 is the perfect.Above 768 phone becomes unstable.

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

1200mhz - 1250mV
1000mhz - 1125mV
800mhz - 1025mV
500mhz - 900mV
200mhz - 850mV
100mhz - 825mV
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.

Sent from my MB860 using xda premium
I may have this wrong but I have read in earlier posts that the power managment on the tegra 2 is only set to work with the perfomace governor. It was tried with the power save governor but that had no effect and was actually more power hungry. I will try to find those refrences when I finish work.
Sent from my MB860 using XDA Premium HD app
thx!
Tegra 2 has a built in hardware governor which is pretty good so there is no need to install software governors, in fact, installing a governor other than performance will impede performance and/or battery life by interfering with the on chip governor.
I believe the Tegra 2 drivers control the CPU speed. It overrides the governor. Performance and powersave are the simplest governors.

In was just looking into this. I'm on neutrino, and no matter what kernel I seem to have, my CPU is locked to the max frequency. My battery life has been brutal and the phone gets too hot even after sending an email!
What is wrong?
Sorry for the ETA, and but I should be more clear..
When I open setcpu or antutu cpu master, and both report the highest selected cpu frequency constantly no matter what the conditions are.
Is the fact that I'm running a java application to control max frequency interfering with tegra 2's governor? Although I've see screen shots of atrix users in setcpu with the freq being not-the-max-freq.
Thanks for any help!
Note: I only ever have one over clock app installed at a time.

I think they're both great you can't go wrong with either kernel. It's like choosing a lamborgini or ferrari, they're both awesome but it truly comes down to preference.
I think I got better battery with faux 31 but I under clocked and undervolted so I can't do a fair battery life test.

I've noticed better battery life as well; not majorly, but noticeably. Although I feel it also has a little perfomance drop. Could just be me, though.

Sorry for a question within a question, but what does undervolting/overvolting do? I've only ever tampered with MHz frequencies.

Don't worry.
Undervolting is basically adjusting the voltages so the cpu uses less voltage aka electricity. It helps a little but it can make your phone unstable so watch out. Of you undervolt use the system tuner app on the market. You should definitely under clock if you want to save power too. When you undervolt be sure to underclock, and don't do it too low or your phone might freeze! That's why your shouldn't go so extreme on it.
Overvolting is basically adding more voltage to the cpu. There is no point in doing it for our amazes to be honest. It is already a battery hog. I guess it can help if you want to over clock a lot but there is absolutely no point in doing that.
In older legacy phones if you wanted to over clock because the cpu would be so weak, like 600mhz then you would have to overvolt to over clock to like 1ghz if you were lucky. Our devices are 1.5 ghz dual core and sense isn't THAT bad. There's no point in doing overvolt in this phone though.
PS, check out my rom in the development section.

I just saw it in Venom Tweaks and was curious. The most I underclock to is 1 GHz; cuts down the CPU maximum by a third and doesn't hinder performance to much. What voltage would you recommend at that clock speed?
P.S. I have I plan on flashing it to try it out when I get WiFi access. Trying to cut down data usage since I don't have WiFi at home.
