[INFO]Understanding overclocking.

Hello XDA community,
I have been on a break from the whole Android development thing for quite a while , I came back to XDA and some mediatek chipset tweaking a week ago or so , and I have noticed several people shouting about overclocking their CPUs and GPUs to gain performance Blah Blah Blah.... If you Don't want all the technical stuff , here's the short answer:
Overclocking has a 50-50 chance to give you better or worse performance
Now for those who still want how to know how overclocking works and affects the performance , Get a cup of coffee or something.So I will start with the most basic question ,
What is Overclocking?
Overclocking is the act of increasing the frequency at which a CPU operates , so it runs faster and hopefully gives us better performance.
For example , Let's take the Mediatek's MT6589 chipset , It has max frequency seen of 1209 MHz (@stock setting).
This means that the CPU can transmit 1200 0s and 1s in a second, to simplify things , lets use an imaginary runner here , the runner has to run on a 100 foot track , when he reaches either end , the CPU registers a 0 or a 1 , the only 2 numbers which our CPU industry works upon , now , at stock un-overclocked frequencies , the runner is easily able to run , 1200 times , in mt6589's case , this is the speed at which your CPU can think , or process , when we increase the frequency , we are telling the runner to increase the times it has to run to and fro from a 0 to a 1 , or vice versa , which in turn increases our hardware's processing power , but , this does not mean , you can go on increasing the frequency as long the device is under operatable temperatures , there are certain factors which matter while increasing the frequency , which leads us to the next topic ,
Voltages , and Overvolting
Voltage is the ingredient that grants greater stable MHz potential to our transistor based computer hardware. Our RAM, processors, video cards, and motherboard chipsets all see gains from overvoltage.
But what does voltage actually do? How much is really too much? What are some dangers to Overvolting? Are there numbers set in stone, or is each piece of hardware different? How can we accurately and safely determine safe overvoltage limits for our expensive hardware, without killing it?If you aren't interested in all the 'how it works' stuff ,feel free to skip this part.
So , to start , let's clear this doubt , overvolting DOES NOT provide extra current , or more juice to accomplish higher overclocks , it just increases the strength of the signal inside the CPU/GPU.
All of todays computers use two binary digits , as told earlier , 0 and 1 , these 0s and 1s occur , or get registered and processed through voltages , voltage high , for a 1 , and voltage low , for a 0 , 0v typically represents a voltage low , or VSS ,Voltage high , or VCORE , is variable for each processor , there aren't any details I could find about voltages of mobile processors , but most of the 28 nm based CPUs have anywhere around 1.2v to 1.5v , but what we need to know is that when our CPU sees a voltage NEAR to the VCORE , it registers it as a 1 , yes , a voltage NEAR to the VCORE , exact VCORE voltages are rarely seen , the part which determines how much near the voltage needs to be is the tolerance , lets say that a processor has a VCORE voltage of 1.4v , with a tolerance of 5% , so , if the voltage reaches 1.35v , the signal will be regarded as a 1 , because the tolerance allows for a 5% loss of voltage , the min. voltage to be seen as a 1 would be 1.33v. BUT , as soon as the voltage exceeds the tolerance threshold , our CPU starts to mess things up , For instance , if the voltage is not able to reach a minimum of 1.33v ,Our CPU will register it as a 0 , the signal strength , which we talked about earlier is not powerful/good enough to reach the VCORE , this is what is known as an unstable CPU. This is the part where you need to play around with voltages. But , wait , why do we need to do that ? , the answer is , if you are at stock speeds , you don't ,the SoC manufacturers have enough brains to set the right voltage for the frequency , and you don't need to do it unless you are seeing the symptoms of an unstable CPU , which includes FCs , failed benchmarks , anything abnormal. So to make things even easier , Let's go back to the runner example again :
If we tell the runner to complete 1400 rounds , which is our frequency , instead of 1200 , on a 100 foot track , we keep increasing the frequency , until we reach a point where it is impossible for the runner to complete the 95 foot-mark , which is necessary for our CPU to register a 1 , and is called back when it hits the 90-foot already , that is when our CPU registers a 1 as a 0 , a VCORE as a VSS , and that is all that matters.when we increase frequency , we shorten the time given to the runner to reach the 95 foot-mark , and depending on the strength of the signal , or speed of the runner , it might or might not be able to complete it .
This problem is solved by overvolting , basically , overvolting means increasing the strength of the signal , or the speed of the runner ,let's take two scenarios here
In this example, the measurement ‘feet’ represents voltage signal strength, and the measurement ‘time’ represents the transition period between VSS and VCORE. Runner #1 can run 100 feet in 20 seconds (Stock VCORE), Runner #2 can run 110 feet in 20 seconds (VCORE overvolted by 10%). Runner #1 can run 5 feet per second. Runner #2 can run 5.5 feet per second. Our overvolted signal switches slightly faster than our stock signal, in the same time period, just as runner #2 can run further in the same time period. Please keep in mind that this is a simple example for explanation, and that signal switching speed is not so linear as "10% overvolt=10% signal switching speed increase".
At a stock frequency, we have 20 seconds to get within transistor tolerance, say it’s 5%, or 95 feet. Both runners make it. Now we overclock our frequency, and shorten the amount of time in which the runners have to get within our transistor tolerance of 95 feet. We increase the frequency, and shorten the transition time to 18 seconds. Runner #2, running at 5.5 feet per second, makes it to the 99 foot mark in 18 seconds, he is within tolerance, and his run is correctly counted as a 1. Runner #1 isn’t fast enough. He makes it to the 90 foot mark in 18 seconds, and is not within the tolerance. Runner #1’s run is incorrectly counted as a 0, and we have instability. In this manner, increasing signal switching speed to directly increase signal strength, overvolting allow us to increase our frequency (overclocking).
Silicon lottery
I wouldn't go stressing too much on this topic , basically , every CPU , even of the same model , manufactured at the same factory , with the same machine can vary greatly , The die inside CPU are made up of silicon , the silicon is extracted from inside the earth in big blocks , the part of silicon which is at the center will give you more overclocking potential and generate less heat , unfortunately , it depends on your luck which chip you get and what is it's potential , for example , I had a AMD FX8320 Desktop CPU , to my surprise , is overclocked to +1100 MHz with appropriate cooling , seeing the performance , I bought another one (exact same model)for one of my other systems , and sadly it overclocked max to +430 MHz , in short , My first chip had won the silicon lottery , while this one was not so good.
In the conclusion , it depends on you if you are willing to take the risk , System boards on Mobile devices have power phases which pretty much only supply the voltage the CPU will need @ max on stock clocks , and without overvoltage , you are pretty much restricted to anywhere from 10-80 MHz , even if magically you are getting stable performance at something around +120 MHz , you will run into issues like heating , potential bottlenecks , battery over-heating , if you consider overvolting , AFAIK there aren't much options for mobile CPUs.the System boards don't have .. ummmm.. good power phases , this is to reduce the battery usage because the CPU won't use more than what is specified by mediatek , qualcomm or whatever.Overvolting also has the effect of increasing the rate of electromigration within our hardware , you can google it to find out more , If you'd like to overclock , Find a Kernel that supports OCing for your device , flash it and then download something like SetCPU , start in increments of 10 MHz , run benchmarks , look for abnormalities and FCs , as soon as you notice one , take one step down , that is the best you are going to get.
NOTEon't just overclock your CPU/GPU to something someone might have accomplished , each chip is different , has a different overclocking headroom and heat generation.
I WILL NOT BE RESPONSIBLE FOR ANY KIND OF DAMAGE TO YOUR DEVICE.

you didn't show how to overclock and modify a kernel, practice is more important than the warnings people often say. It's funny how many people just talk about overclocking and danger, then fear and prevention! But there is almost no presentation on how to guide overclocking!

Stock Kernel Optimisation

Hello M2 users, y'all probably wondering what did I mean by the thread title above so I'll get straight to the point nice and simple.
Using a stock kernel sucks, any CPU Tuner will go bonkers adjusting frequencies only to see it revert to stock again. So, while browsing for ways to optimise performance and battery in the Xperia, I came across this guide (now updated to this) on our Interactive governor. While it's on a different phone, the explanations are clear enough to tell anyone that yes, this can be adapted so long as you are rooted.
So read the whole post to give yourself an idea on the functions available for you. I use Kernel Adiutor for this as it seems most reliable.
But first, go into your build.prop files and edit this code:
Code:
ro.min_freq_0=300000
Set the frequency to 300000 (300Mhz) and restart or your phone will always be stuck on a higher frequency.
Also in the Kernel Samepage Merging, turn it off. There isn't much of an impact between battery and performance so this function is useless.
So now head into the CPU section, towards Tunables and add the following values according to the screenshot.

This gave me 50% battery usage over 26 hours, with 5 hours of Screen on Time used by chatting, gaming, and web surfing. Pretty good looking at all the times I've run the battery with less usage.
Anyhoo, I hope these settings are useful for y'all and if anyone has any modifications to these settings please do share it with your results. This may perhaps be the only guide where we control the governor on a deeper level rather than taking it as it is, so let's squeeze as much juice out of this phone as possible.
Update: These are the settings I've settled with, no negligible battery life and not much of an impact on performance. The voltage tables for the SD400 looks to be dynamic so you can't get an exact reading and anyone who looks at it will suggest you buy a new phone instead >.>

Right now you can only add multiples for above_hispeed_delay and target_load. Just tap the space bar each time you add in new values and the app will auto-arrange it for you. If it still doesn't work, what kernel are you using?

Can you repost the photo or write the values please?

I spent last week trying to study and understand those govenors.
Since yesterday, I was trying and tunning the stock interactive govenor
I didnt notice any major changes in performance but I was surprised by power consumption
Ex: I used to play Solitaire everyday more than 2 times a day, each time I spend like 1 hour and my battery drops like 10%
After tunning the interactive govenor my battery drops like 4-6%
Which means its much better than stock
I'm using EagleExperience rom which come with stock kernel
Anyway I just want to know your tunnables because the photo you posted is not opening
I want to compare them with my numbers
Thank you for this post and sorry for bad english
It's not my first lang.

These are my current settings, the 300Mhz and 787Mhz share the same voltage and any higher frequency has the same voltage too so it's more efficient to use Sony's settings. The only difference in here is I used Intelliplug to better control how they ramp up.

Is that config fine ? I tried semil's config its battery performance was great but i think it is slow config.

I try not to limit my frequencies since the point is to go high performance only when needed. I'm not sure about your config since I never turn off hotplugs.

How To Guide [TUTORIAL] how to set the screen refresh rate to 90 Hz

[Tutorial] How to set the screen refresh rate to 90 Hz
90 Hz is the best compromise between smooth experience and battery consumption, MIUI on poco x3 pro does not support the option to set 90 Hz by default.
How to do it
1) Go to settings -> about phone -> and click 7 times on "MIUI Version (for POCO)" until you see a message that you have become a developer
2. go back to the main settings menu, then into additional settings -> developer options and find the option "show refresh rate" and then click. Now you will see the current FPS number in the upper corner (60 or 120 depending on what you have chosen)
3. Go to apps -> manage apps and search "battery and performance", then select clear data of this app
4. Go to the google play store and download SetEdit (Settings Database Editor)
5. run the application, and at the bottom look for the option "user_refresh_rate"
6. click on this option and edit the value to 90, save the changes and then you can exit the application
Enjoy! When you exit the application, the FPS indicator should now show 90 instead of 60 or 120

I had to restart the phone afterwards to make the change take effect, just in case anyone else thinks the above hasn't worked.

If I were to do this with a rooted phone, would this be under build.prop?

not working and then I restarted the phone but still not working.

it wont because guide is not complete(even though it is kanged). if you look at old x3 nfc's guides/TG groups, you will see proper steps. after setting the refresh rate by using "setedit" app or clearing data & cache of "battery and performance" app, you need to at least once open "recents" otherwise it wont take effect.

I tested it today on xiaomi.eu ROM and it doesn't work there

ArrowOS has the feature built-in:
Settings –> Display –> Device-specific settings (Refresh rate configuration) –> Minimum refresh rate

It work for me on MiuimiX ROM

If I'm not mistaken, I don't think so, you just need to set a constant refresh rate, e.g. 60,90,120 Hz

As easy as it comes, thanks for the input friend, 90hz is perfect

works in MIUI Global 12.0.6 stable. Thanks bro

How about battery consumption, better than 120hz adaptive?
And how about if i want back to normal again

Can we use this app to elevate de screen brightness Beyond 4095?

Good question. How to change refresh rate simply by editing value in default.prop?

It worked for me and i didnt do the "3. Go to apps -> manage apps and search "battery and performance", then select clear data of this app" part.

General [Update] Xiaomi 12S Ultra GPU OC w KonaBess (Root)

I was able to hit 900mhz on gpu cores
and basically one of the fastest android devices in the market...
If anyone else has rooted device, please share your oc results!
update: so I was able to hit 910mhz after all tweaks,
and seems like 14 is practically the max for bus speed.
I tested 16, but from 13 it start to make no difference
and I get 2849 with bus speed 13 and 2851 with 14.
from 15, its the same so I decided to play safe. Stock bus max is 11.
Stock 900mhz uses Turbo voltage, and I can finish benchmark without visual glitches with NOM, which is 4 step down from the Turbo voltage. So I'd call that a significant undervolt. Well havent tested for extended gaming sessions, but for benchmarking, this is as far as it would go.
Also lowered stock 220mhz to 150mhz and gave RETENTION(lowest voltage) from stock MIN_SVS, so it would save more battery during idle.
I have attached KonaBess config file below, txt file, but keep in mind these are my settings for my device, and yours will be different. so take it with a grain of salt and only view as a guide or reference.
I am confident to say that this is clearly the max it can go with vanilla stock.

seems like I would need a custom kernel to get stable past 900mhz.. no matter what I do, even though 900mhz runs fine on normal voltage, adding like 902mhz and applying turbo voltage causes stuttering during benchmark or any gpu utilization. so I am focusing more on undervolting atm. I mean, already one of the fastest devices on the market and simply undervolting it allows the device run cooler and stay longer on high frequencies

I just have limited access to pc atm (to monitor frequency) and I noticed android not using highest step all the time but using one two steps below(say I add 900, it uses 862, adding 910, 900 and 910 sometimes) based on kernel manager apps - which is not super accurate. I have no other ways to confirm if single 910mhz is fine. As I see no negative impact of using double steps, I just left it there to be sure.
If you can monitor gpu frequency and single step works fine for you, please let me know!

This mod isn't working correctly I don't think, I am attempting on putting together a magisk module for overclocking cpu cores 0-4 a tad amount to their max range on Walt governor, but I think konabess isnt correctly overclocking as /sys/class/kgsl/kgsl-3d0/max_pwrlevel and other parameters aren't changed

Please tell me if it is necessary to enter these commands through Windows CMD or is it enough to install the application and use your settings? For example, without these commands, after changing the frequency on the OnePlus 9 Pro, the phone stopped booting.

How To Guide Optimise Stock Kernel Scheduler & Governor Setting

So, after months of using Pixel 7 family, surely we all know that Tensor 2 is not exactly the best flagship SOC in term of raw power or energy usage, probably due to it's "Exynos Genetics Trait"
that being said, doesnt mean it's down bad. And with some optimisation, we can always try to make it run better. One of the example is by seeing how much better it run on custom kernel. But what about other stock kernel user ?
Well, fortunately, as long as we have root access, the stock kernel still allow us to play with some parameter. And here are some tunables parameters that i use to balance the energy usage and responsiveness of the device. (my aim is 10% battery for 1 Hour of SoT and ±0-1% decrease during 6-10hrs idle)
If you want to know more about each parameters, you can google a lot of linux kernel documentation (like here for example : https://access.redhat.com/solutions/177953)
but for now i'll just write down the change and my configurations. (I used EX Kernel Manager to change the parameters) :
CPU Section :
Switch governors for all CPU clusters from 'sched_pixel' to 'shedutil'
Open "Governor Options" and change the 'rate_limit_us' for all clusters from '10000' to '0'
Open "CPU scheduler options" and use bellow value for respected parameters :
sched_wakeup_granularity_ns : 10000000
sched_tunable_scaling : 1
sched_min_granulatity_ns : 2000000
sched_latency_ns : 12000000
Memory Section :
Disable "ZRAM"
That's it for now. Try and feedback if you find any improvement in your energy usage.
I've been using it for weeks, and pretty happy especially with idle drain. As for SoT, normally i end up with 5-6 Hrs screen time when i down to bed with ±30% battery remaining.

that being said, doesnt mean it's down bad. And with some optimisation, we can always try to make it run better. One of the example is by seeing how much better it run on custom kernel. But what about other stock kernel user ?
Well, fortunately, as long as we have root access, the stock kernel still allow us to play with some parameter. And here are some tunables parameters that i use to balance the energy usage and responsiveness of the device. (my aim is 10% battery for 1 Hour of SoT and ±0-1% decrease during 6-10hrs idle)
If you want to know more about each parameters, you can google a lot of linux kernel documentation (like here for example : https://access.redhat.com/solutions/177953)
but for now i'll just write down the change and my configurations. (I used EX Kernel Manager to change the parameters) :
CPU Section :
Switch governors for all CPU clusters from 'sched_pixel' to 'shedutil'
Open "Governor Options" and change the 'rate_limit_us' for all clusters from '10000' to '0'
Open "CPU scheduler options" and use bellow value for respected parameters :
sched_wakeup_granularity_ns : 10000000
sched_tunable_scaling : 1
sched_min_granulatity_ns : 2000000
sched_latency_ns : 12000000
Memory Section :
Disable "ZRAM"
That's it for now. Try and feedback if you find any improvement in your energy usage.
I've been using it for weeks, and pretty happy especially with idle drain. As for SoT, normally i end up with 5-6 Hrs screen time when i down to bed with ±30% battery remaining.

Someone said that it reverts back once you reboot?

In the Franco Kernel Manager, there's an option to "keep" the new settings on a reboot. (Not sure about the EX Kernel Manager.)

Right, it reverts back for CPU Governor (Cluster 3) after a reboot. (with EXKM)

Then I tried with FKM and problem is the same.
I will see after the night how is my battery drain.
But i can't complain because i loose only 2 or 3% during night (8h)
(Bluetooth and 5G on) No wifi because 5G signal is good.
No custom rom, rooted, january update.

It's expected that it reverts back to default because it's controlled by multiple things. People shouldn't change the governor. There is a write-up on this in Freak's kernel thread.

Actually you can change the CPU governor from the default one to one of the additional existing alternatives.
The issue is just that the frequency scaling driver for the affected CPU cluster(s) will break if the PowerHAL detects that the Sched_Pixel governor isn't "there" anymore for doing the job that it is supposed to do.

I never wrote you can't change it, I wrote people SHOULDN'T change it to avoid the issues you mentioned.

You say to try to deactivate zram. Is there any real benefit? Zram is useful?

You save CPU cycles at the expense of additional vRAM.

If you use smartpack kernel manager there's an option to apply all changes with a script on boot. That's the way I've always worked with kernels that won't allow changes to stick on boot
