Overclocking Kernels for the TF701t

Hi, does anyone know of any kernels available for the tf701 so we can overclock/underclock the processor better? I still am kind of new to this forum. I want to do this for overall battery life improvement and also performance improvements as a bonus. thanks for your help!!

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

with the trickster mod, would I be able to set profiles for it when I do things like turn off the screen? thanks for the suggestion!!

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.

Custom roms, or stock rom modification?

Hi,
im on stock rom, with bootloader unlocked and root installed. my deivce is still very hot even after system configurations, so id like some advice on how to tweak the kernel or improve performance, make it not overheat, install custom roms or delete system apps and so on.
Ive tried uninstaller system applications or bloatware, tweaking the kernel with CPU Tuner, installing and configuring the L Speed app, who i was someone had awesome resaults with here: http://forum.xda-developers.com/xperia-z4/themes-apps/one-to-tweak-apps-l-speed-t3350288
i only get around 2 hrs of screen on time with my deice, and a lot of heat, i saw it over 80 degrees yesterday...
id like some good optimization and battery life for the device, as im not able to do so now...
thanks in advanced

Ive been using that firmware sins the day it released (a weak ago almost)? but no change there...
what i have done now is done some heavy modifications to the kernel and some CPU governors.
I flashed this Kernel: http://forum.xda-developers.com/xperia-z4/development/kernel-andropluskernel-t3392772
the kernel works like a dream after under-clocking it with this program: https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=no
Used the "alucard" governor, CPU is sitting around 60 degrees when using the camera, and its a bit laggy, but much more survivable that it was before...

This Kernel is the best you can do, perhaps you can try to deactivate one or two of the big cores.

I never tweaked anything but mine is only hot when I play heavy games and record video for more than 20 mins (720p)
Anyway your lag is too much or just a little bit???
And one thing I use stamina mode whenever I'm about to do something CPUy
So try it without tweaks and tell me what's the result.

I get the stamina thing, id do that too if i did not need the screen brightness
The laggs are not small, im talking CPU om 80 degrees an so hot that i can not touch top backside of the phone
and thats withou any tweaks on MM .244 with everything stock. Ive also tried it with root, but really that does not make any differense, i need to edit the kernel to be able to use the camera, or else it will shut down when recording in 720p.
Anyways, underclocking the device for me, actualle made it faster in my case, i have no idea why makes no sense, but there is no throtteling and cpu struggles when underclocking it, so now it relly smooth, a lot smoother than on stock .244 MM,
Hope it help!

Well it gets hot but I don't mind about the heat, I'll throw it in a glass of water or inside the refrigerator if it's too hot [emoji48] . And I didn't underclock it. It's still running stock governor.

Supertweak for amazing performance b383 b386

Hey guys after long research i finally found how to solve forever the gaming smoothness and all performance with our p9
You just st have to be rooted and paste and replace those 3 files inside the . zip to this directory
/product/etc/hwpg
I could play all games, chain lots of benchmark without any lag
You can look at the screenshot to see my performance on antutu before my scores goes to 97000 to 83000 after 3 test.
I can also say i'm able to play modern combat 5, gt racing 2 without any lag at all
Test and tell me how your P9 look like a P10 now

On this screenshot you can see all improvement you'll get in front of stock P9 with really better scores on games

I think thats the max huawei allows, there can be more if a custom kernel or sources exist.

To be honest i have to test one fully day but it seems very good cause i just modded thermal configuration to haven't this huawei's disaster throttling.. So, task are done faster with higher cpu frequencies but with shorter time... I did some game and i can see my battery stay very good!
Plus when i saw configuration of those thermal files i could see it started throttling at 44 degrees.... So it was very low
If you want i can post a screenshot of my cpu temp with this mod but it's also very good a'd nit very high

I was test it now on antutu... Original settings: 3D score 10641/total 86541 and text "game performance is mid-level". With this supertweak: 3D score 20399/total 99597 and text"run smoothly for 3D games in mid-quality mode" it's better and faster, but only thing: is this safe to use this tweak ?

For me it's safe i just disable the hard throttling part made by huawei and if you have kernel adiutor or cpu z to control your temp you will see it's not so hot, plus i'm sure always throttling and playing with cpu and gpu freq so much finally eat battery.
Attached a screenshot of my cpu temp

Id either throttling big and work more with little to save battery.

With Geekbench There is no difference between orginal and Supertweak, with AnTuTu I got 98200 Total with Tweak and 94820 without.

Yes if phone is cold but if you do 3 or 4 bench you will see score with tweak will stay same and without tweak score will decrease to 80000

So i am really not good at these sort of things, can someone explain me detail by detail how to do this ? I'm afraid of messing things up, please help me

daily use
Is less heat throttling useful for everyday use without gaming?

For now after three days i can say there is no overheating at all with this tweak, it's super stable and i'm happy with battery now, i just plugged in my phone to charger now since i plugged it off yesterday at 6pm,i played a lot with clash royale and watched some video on youtube and doing facebook

First you must have a rooted phone and replace those files in the good folder with an app like root explorer and after it's done you just have to reboot your phone

Well I'm using kernel auditor. Do I need to disable the tweaks on this first?

Hello,
What's the diffence with setcpu for exemple....?

With setcpu or other cpu manager app, you can change governor etc, but you can't disable the throttling made by huawei and then without this tweak your phone will slow down even if you put freq to max or governor to performance or not

[EXPERIMENTAL] Throttling and it's caveats

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!

theres currently 2 thermalmod magisk module for our device, one is jthermal and the other is thermalx, currently using thermalx and it essentially removes thermal throttling, highest temp i got was 48°c playing pubg at smooth+extreme settings at noon.

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)

-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!
