If you have undervolted your Nexus 7 or any other tegra 3 based device please post the results here so I can throw them into a Excel sheet for development.
Using advanced mathematics and complex formulas I will make a undervolted kernel that's stable for everyone. For that, I need ideally 30 results or more. Less is ok but more or equal is better.

I also accept 1 frequency result. You don't have to undervolt everything. I favor the last known voltage that crashes as well if you can send this I am even more happy.

In order to use "advanced mathematics" and "complex formulas".. You might want to provide a format for "the results" you want people to provide.. Without a stream of formatted data to input your "complex formulas" and "advanced mathematics" is impossible..
"Advanced mathematics" and "complex formulas" sounds like you are doing an infomercial.
Pure waffle.

ha! good luck. considering some devices arent stable at all when undervolted just a tiny bit, and otbers are stable with a lot of undervolting, you have a tough road ahead of you.

Might as well be honest, set him on the right track early in his dev career rather than him rely on buzzwords and fud like some people do.
These are forums for android devices, not Apple devices, the reality distortion field doesn't work here, fancy marketing terms should be left at the door.

My Galaxy Nexus is proof of undervolting being unstable using software while being stable with manually programming the voltages. So I am going to give this a good shot anyway.
My Galaxy Nexus uses SmartReflex to undervolt.
Look at this table I made:
https://docs.google.com/spreadsheet/ccc?key=0AuqacKmGLKJ6dEdJZG5QTmNtQnoyYk0zbm5IanluMHc#gid=1
You see the core or gpu was already crashing at 974mV, which was the reason why I stopped undervolting using the thread. But don't give up, I tried again using SmartReflex because I felt I should be able to get lower. And now I am at 911mV but I did not try to get lower yet.
I plan on undervolting by actually programming it. I don't know how you guys undervolt for the Nexus 7, since I am fairly new with this device.

Using that I can calculate which voltage to take that will work for 90% of us or 99% of us or maybe 100% ?
For that I need some results. The more the better.
The only voltage settings that will work for 100% of people are stock voltages.
you will run into endless problems if you release an undervolted kernel because what works for 75% of people won't work for the rest.
If you adjust voltages to include more people the people that can handle the lower voltages aren't getting the full savings their device can handle. Which defeats the point of releasing an undervolted kernel to save battery.
Undervolting should be up to the individual, just release with stock voltages and make a guide showing people how to undervolt.

^^ Truth
I've done a bit of pc overclocking over the years and we'd always seek out the best steppings to find cpu batches that would give a better clock speed for less volts. What would work on one person's cpu wouldn't work on another sometimes even within the same stepping. (My current machine is getting long in the tooth but it's running a 33% OC below stock volts and stable as a rock.)
When the N7 cpu's are tested the stock voltage is the point where 100% of them will run without issue. Certainly there are many, maybe even most N7's that will run undervolted but until you try it you just won't know. Undervolting needs to be done on a case by case basis.
I uv by 100mv on every step on Franco kernel and I've never had a sod or reboot. Maybe you could release different versions like light, medium and heavy to cater to different users that have sets than can uv more or less. To address all these people naysaying I say just go for it, don't let these people dishearten you from what you want to do. I'm sure there will always be users who are willing to try
sorry to break the fun lol
Opened a thread with undervolting settings in different situation. For now i think its the lowest possible

That's exactly the same as what I have done. 100mV right across the board, and I have also never had a reboot or any other negative effect from doing it. Just a bit more battery life.
I too UV 100mv across the board. Never had an issue. And I OC up to 1.6ghz.

Same here, no issues with 100mv UV on stock speeds. What would happen if we went too low, would it fail to boot at all or is there some safety mechanism that would allow us to boot into boot loader?

When either OCing or UVing, you should ALWAYS test out the changes prior to saving them as a persistent boot state. This way, if you set something too high/low and it proves to be unstable, if you restart the device it will revert back to normal.
In the event that you OC/UV too much, yes, you would see signs of instability. In some cases it could show up as soon as you applied to change, in other cases it could take a while to notice. For example, some games or other high processing powered activities could FC/crash. Or your tablet might freeze or reboot. But again, as long as you didn't save your changes as a boot setting, it will be fine once it reboots.
In the event that you did save it, and the settings were unstable for your device, you could boot up into recovery and then manually erase them from taking effect. Recovery doesn't use those settings, as it's technically a different OS. But that can be complicated a process for some. So test test test save. Or don't save and just apply them manually.
Two other points:
Yes, most (all?) devices do have safeguards to protect itself against permanent hardware damage from OC/UVing. If it gets too hot, they will often shut down to protect themselves.
And just because one device can handle being OC'd or UV'd to a certain level doesn't mean they all can. Very minor differences in each component can impact one devices ability from another. The manufacturers only test to see if they can handle the published speeds/etc., but in many cases they can go higher if set to. In others, not so much.
Thanks for that phonic. Given the range of ROMs and kernel's available and the improvements already built in, under volting may not help a lot but every bit helps. Eg this screen on time is pretty good.Close to six hours screen on time with iirc 35% battery remaining.
Paranoid android with motley kernel. I don't over clock the nexus 7 as its fast enough. In fact I under clocked it to 1000 MHz max before and it was still fast but the screenshots are at stock volts and speeds.
it's actually plain simple. If everyone posts results. I can make a kernel with voltages that work for 75% of all people or maybe for 95% of all Nexus 7 owners.
It's called mathematics. But to do that I need as much results as possible.
Easy to do if you know what you are doing, right ?

There are none currently.
Not sure the device really needs it either. It's very fast as it and would only generate more heat and worse battery on an already hot device.
Tweaking the kernel and rom are much better options (CROMi-X )

I essentially wanted to use SetCPU in order to dramatically underclock the processor during sleep and slightly underclock it while its screen is on (because who needs all this processing power really?). This could possibly stretch out my battery life by another day. Do you think that will be possible to do when I install a different ROM on the tablet? (like yours for example)
Ah ok - download trickster mod and set the min and max freq there. SetCPU is years old and won't work with our device

Nope - it just sets the min and max.
I wonder why it gets hot though. I thought these are SoC's and aren't supposed to get hot. The tf101 didnt get hot at all. But if you overclocked it to 1.6 it started to get warm.
Does anyone know if this happens as regularly on cm11 or another aosp ROM? Also, what's a good max level to clock it at so I don't constantly worry about the heat issue?

What exactly are you worried about? You can't clock it past 1.9GHz anyway which while it might get toasty it won't fry an egg or anything.

If the app doesnt tell you, Wipe data on the app and reboot. Stock voltages are applied every reboot, until the app applies custom.

Undervolting isn't going to do much of anything for long term battery life. CPU's are very minimal battery users for most day-to-day operations, so your actual battery life gains are going to be minimal, <5%, if you notice anything at all.

I'd say even less than 5%, more along the lines of less than 1%. but its decent for lowering temps slightly as well. me, I dont undervolt at all, yet see from 5.5-6.5 hours screen on.

Because you sir, are a wizard.
Hello guys I got some huge problems here.
I recently switched from my Z2 to the Z3+ and actually like the phone but the overheating is insane and especially kills Pokemon Go through CPU throttling, which runs smoothly on my old Z2 .
So far I am on 253, cleaned it up and tried a self modified and the zach beta9 Kernel and and runs quite bad on both. Is heating a lesser issue of 224? I actually do not want to reflash the whole system to 224 just to find out it doesn't get better.
Also is there a way to undervolt/underclock? I can change settings in Kernel Aduitor but I have the feeling the phone doesn't really care.
Help much appreciated - thanks!
Try Zach beta 8 kernel. Limit max cpu frequency by kernel auditor.
Still it's only your Goodluck if your device cools down. It's a bitter truth about this model.

but do underclock and tell us the results!

Thank you for the replies!
Tested zach beta8, didn't help. Now I am testing http://forum.xda-developers.com/xperia-z4/orig-development/kernel-om5z-kernel-t3421630/ as suggested and if that doesn't help much also with http://forum.xda-developers.com/xperia-z4/general/kill-overheating-flash-zip-t3421782.
And Stamina Mode helps at least a bit.
Statusreport: It always runs bad. But best at the moment with root patched Stock Kernel (253) and that underclocking zip. Although I think that underclocking doesn't really help at all.

What are your temps? When does it start to throttle? Done any thermal-conf configuration to allow more heat?
---------- Post added at 21:03 ---------- Previous post was at 20:58 ----------
I know that @Trilliard has a very good and stable cpu governor where he has disabled two of the little and two of the big cores, this helps a lot if you underclock the remaining 4

Thats what i thought as well i have my own here, its based on another persos post, but i dont remember where...
Anyways, his camera mod worked, but cpu throttle was not tampered with, and it caused a very unbalanced throttling... Ok yay i can use the camera linger and fluently, but when i exit the camera app, i cant use the phone couse its runnig at 348 mhz...
So i i did some modifications to it cpu never get under 840 for little cores, so your phones menues end web browsing are always safe from performance drops.
I made it to be able to play Pokemon go, and achieved a lot better resault than without any changes.. still prefer playing on my shield tablet, but if i dont have it around when theres a lot od pokestops nearby, then this will work for me.
While playing Pokemon go it does not go over 80 degrees, but using snapshat it can get to 85, so dont use snap for to long
Let me know if it worked for you!

Hmm. Still runs ****ty.
Can anyone give me a short guide how to edit thermal and governors?
According to my observations the phone gets hot and then cold. I think the throttle is more aggressive and needed and I want to make it less aggressive.
Update:
I made my own modifications to the thermal engine. It is pretty bad for battery I guess but I had a very good expierence playing Pokemon Go with it today. Yes the phone gets hot. Like it doesn't drop below 70°C while playing and regulary hits 80°C but it works good. No dark screen, no 0 CPUs downclocking. So far it's fine for me, maybe I get squeeze even more out of it.

Allright thanks i might try your conf if i cant get mine to work like I want
While being owner of my Redmi Note 7, which definitely has some issues, I started experimenting with it.
Throttling is a common term amongst electronics and such. It's a way to safe our precious silicon from eventually cooking under high temperatures. There're a lot of issues involved here. Let me explain:
Xiaomi's belief is maximizing battery life while forgetting about optimal device's performance. Here's the issue, though - neither of which are properly calibrated. For a battery of this size, you would expect something better, but it's not. Looking through system files, there are several thermal config files, which simply tells to the thermal-engine binary at what state device should throttle. Sounds like a good idea, right? Yeah, not quite.
Upon opening these exact config files you see several lines, which describe temperature thresholds and which frequency device should start to use under it's determined state. There's more to this - GPU gets less voltage when it's getting warmer, thus reducing the ability for GPU to reach higher power levels. Everything would be great, if the device wouldn't start to throttle it's clocks at 45° degrees, which is basically nothing.
After seeing device's guts it's safe to state, that our phone has proper cooling done to it. Sure, it's basic, but with that much space and the price this phone is built for, you couldn't ask for better cooling.
So, what can you do to it?
There're several solutions.
-Deleting thermal-engine entirely and forgetting about the problem. Here's the thing, though - it's really dangerous, because not only you lose the ability to monitor your battery's temperature, you could cook your phone while charging. Charging throttling is a thing too, when phone slows down pulling current from a wall as soon as you are doing something intensive. It's a dirty fix with a lot of risks involved.
-Modifying thermal config tables. This way you could ensure device's safety while having optimal device's performance.
-Mounting hugeass cooler at the back of your phone or better yet - mounting cooler straight to the cpu silicon. Jokes aside, this is not recommended at all, unless you're insane and don't care about sacrificing device's size.
I'm actually thinking about making completely custom thermal tables and make them compatible with Magisk. Even if Magisk method wouldn't ensure enough confidence, I will make flashable zip for recovery flashers. Everyone's happy.
FAQ
-But the device has kernel level throttling monitor. That one works too, right?
-Yes, but it does not do anything related to cpu clock management and such. All it does is turning off your device entirely when undesirable temperatures are reached. Thermal-engine is what's monitoring temperatures and adjusting clocks when necessary. Kernel level throttling is there for additional safety, in case thermal-engine is not working properly.
-My device runs great. Why bother modifying what Xiaomi did?
-It's up to you to do anything with your purchase. If you are happy, it's fine, leave it as it is.
-I noticed hugely increased benchmark scores and games working smoother after deleting thermal-engine. Is that normal?
-Exactly. Here's your answer to what thermal-engine actually does. It hampers our device too much.
-When are you going to research this modification?
-As soon as I'm free from doing routinal things: school, job, home and such.
BONUS TIME!
Gfxbench 3 Manhattan 1080p offscreen scores for your reference:
With thermal-engine running: 15fps
Without thermal-engine running: 23fps
REMEMBER, I'M IN NO WAY RECOMMENDING YOU TO DELETE THERMAL-ENGINE. IF YOU DO THIS, IT'S YOUR RESPONSIBILITY WHEN DEVICE STARTS COOKING OR CATCHING FIRE. THIS IS SORT OF MY OBSERVATION OF A PROBLEM OUR DEVICE HAS. EVERYTHING IS AT OUR OWN RISK!

but here is the link JThermal, I took the file I downloaded from telegram and uploaded it. To install use MAGISK!

Thanks! I got a hold of the thermalX one. Registered on 4pda and downloaded it.
Install ACCA from magisk and you'll be able to control max temperature while charging

I have tested the jthermodv3 and my battery icon went red warning. I have disabled it instantly and restarted and now vibration doesnt work.
do not make the mistake i did. f*ck this ****.

Disable battery saver.
edit: where did u get v3? I'm using v2, I'd like to update.

Yesterday I flashed this module on latest xiaomi.eu beta and everything is working perfectly. Maybe it works only with MIUI based ROMs?

It "works" on any rom, but it is not recommended, it lets your phone get really hot, and it destroys the battery life

Yes, I know. Everything in life is a trade. I'm willing to lose some battery lifespan for performance. Not being able to play games @60fps is unacceptable.

Possible. I was at PE 10 Beta. Maybe it's because of the SDK differences.

Most of the custom roms reuse already available binaries and stuff from MIUI, unless dev is clever enough to transition fully to CAF, so it should work, I think.
From what I've seen, MIUI is not any different when it comes to thermal configurations. Both of them use the same binary and same configs (they might be changed, not sure)

While being owner of my Redmi Note 7, which definitely has some issues, I started experimenting with it.
Throttling is a common term amongst electronics and such. It's a way to safe our precious silicon from eventually cooking under high temperatures. There're a lot of issues involved here. Let me explain:
Xiaomi's belief is maximizing battery life while forgetting about optimal device's performance. Here's the issue, though - neither of which are properly calibrated. For a battery of this size, you would expect something better, but it's not. Looking through system files, there are several thermal config files, which simply tells to the thermal-engine binary at what state device should throttle. Sounds like a good idea, right? Yeah, not quite.
Upon opening these exact config files you see several lines, which describe temperature thresholds and which frequency device should start to use under it's determined state. There's more to this - GPU gets less voltage when it's getting warmer, thus reducing the ability for GPU to reach higher power levels. Everything would be great, if the device wouldn't start to throttle it's clocks at 45° degrees, which is basically nothing.
After seeing device's guts it's safe to state, that our phone has proper cooling done to it. Sure, it's basic, but with that much space and the price this phone is built for, you couldn't ask for better cooling.
So, what can you do to it?
There're several solutions.
-Deleting thermal-engine entirely and forgetting about the problem. Here's the thing, though - it's really dangerous, because not only you lose the ability to monitor your battery's temperature, you could cook your phone while charging. Charging throttling is a thing too, when phone slows down pulling current from a wall as soon as you are doing something intensive. It's a dirty fix with a lot of risks involved.
-Modifying thermal config tables. This way you could ensure device's safety while having optimal device's performance.
-Mounting hugeass cooler at the back of your phone or better yet - mounting cooler straight to the cpu silicon. Jokes aside, this is not recommended at all, unless you're insane and don't care about sacrificing device's size.
I'm actually thinking about making completely custom thermal tables and make them compatible with Magisk. Even if Magisk method wouldn't ensure enough confidence, I will make flashable zip for recovery flashers. Everyone's happy.
FAQ
-But the device has kernel level throttling monitor. That one works too, right?
-Yes, but it does not do anything related to cpu clock management and such. All it does is turning off your device entirely when undesirable temperatures are reached. Thermal-engine is what's monitoring temperatures and adjusting clocks when necessary. Kernel level throttling is there for additional safety, in case thermal-engine is not working properly.
-My device runs great. Why bother modifying what Xiaomi did?
-It's up to you to do anything with your purchase. If you are happy, it's fine, leave it as it is.
-I noticed hugely increased benchmark scores and games working smoother after deleting thermal-engine. Is that normal?
-Exactly. Here's your answer to what thermal-engine actually does. It hampers our device too much.
-When are you going to research this modification?
-As soon as I'm free from doing routinal things: school, job, home and such.
BONUS TIME!
Gfxbench 3 Manhattan 1080p offscreen scores for your reference:
With thermal-engine running: 15fps
Without thermal-engine running: 23fps
REMEMBER, I'M IN NO WAY RECOMMENDING YOU TO DELETE THERMAL-ENGINE. IF YOU DO THIS, IT'S YOUR RESPONSIBILITY WHEN DEVICE STARTS COOKING OR CATCHING FIRE. THIS IS SORT OF MY OBSERVATION OF A PROBLEM OUR DEVICE HAS. EVERYTHING IS AT OUR OWN RISK!

Can you tell me how to delete thermal engine please iam currently using redmi note 7 pro.Iam getting a lot of throttling please help
