I have a ZenFone Max Pro M1, with custom PBH kernel (4.4.198, EAS, OC). After a while of finding how to overclock GOU, i figured out it is not needed, just decrease GPU pwrlevel to get more performance because higher value = less clock speed. Look in kernel source, i found default value is 3, and speed (not clock) is 6500000, if i change to 2, value is 6750000, 1 is 7000000 and 0 is 7500000. I want change to 1 but every time i change it, it automatically return to default value, 3. I tried many software with no luck. Pls help.
Note: The kernel's developer is inactively. If anyone can help me, post a reply.

Help about GPU Power Level. I have a ZenFone Max Pro M1, with custom PBH kernel (4.4.
try to set any manger to AUTOSTART form setting
So I put my GPU power level to 0 and I got my maximum initial GPU performance with is 650mhz, and when put to 6 I get 133MHz; So my question is what's then the difference between initial and max-min GPU performance....I can set my GPU governor to performance and I will get 650mhz all the time so what's the use of this initial GPU performance boost? If I increase the number can I in fact lower the tdp of my GPU and have better thermal performance. Some help will be appreciated, I couldn't get any clear explanation anywhere....I can't add a picture cuz I didn't post 10 post on XDA platform:crying:

I have the same question. Have you found any answer?

just wondering, there's so much talk about overclocking CPU.
why no discussion on overclocking for GPU? is it possible?
i think if the higher GPU clockspeed improve performance even more than CPU clock speed, doesn't it?
if i understand correctly, galaxy nexus GPU is the same as galaxy S1. but with much higher clock speed. So the GPU speed can be made higher right?
Some kernel, as Siyah allows you (with extweaks) to overclock gpu up to 400 mhz, but I think this is useless, no app need more than 200-267 mhz.
A good idea can be downclock gpu and cpu frequency and decrease voltages to save battery.

I think (coz i saw this about a week ago haha)there are two GPU states low 200Mhz and High 267Mhz..
Please, anyone correct me if I'm wrong..

Gpu steps are 3. According to information provided by extweaks default frequency values are 160, 267, 267, but you can set as you want.

That is the "Performace" setting of siyah(160, 267, 267). Or maybe it is the default but siyah considers it as a performance setting

I'm using CM9 RC1 on a Note right now and the default settings are 200 Mhz min and 1.4 Ghz max.
Is there any benefit to using a higher min like 500 Mhz or is it just a waste of power? I'd assume it would be slightly faster upon wake up.
You can always try, as long as you know what you're doing. Are you familiar with overclocking, and how to test higher clock speeds without having them set on boot until you have tested for stability. 200MHz seems a bit low for echo 0, but you can try to start bumping up echo table 0 values slowly and at small incremental increases. For instance, from 200MHz, go to 220MHz and test, then if stable bump up to 240MHz and so on. Jumping from 200MHz to 500MHz may not be the best idea without a "seasoning" of the CPU at echo table 0...

I've overclocked on PCs before but I'm not overclocking. I just want to know if there's any benefit to setting a higher min speed.
It probably will not yield any performance increase to clock your lowest frequently scaling higher, since likely your device's governor (I'm assuming) is set to mot_hotplug.
Unless you're using a governor setting of "performance" or the like, your CPU's governor will step down through the kernel's frequently tables as determined by the load. Again, unless you're running a governor setting that does anything but what is similarly done with mot_hotplug the CPU's core(s) will be turned off when not demanded.

Ive been using android overclock. On demand. and staying at 350 to 1420 and its been working really well as far as battery usage
I´ve been using ondemand-noop min 245, max 1024
Ok. That was 2012. Now is 2020. Updates to minimum and maximum for Android 8/9???

Just to have said it: CPU speed affects performance of Android device, doesn't depend on Android version. The more a processor is stressed the more the battery is drained. IMHO CPU speeds matter less than they did in the past, thanks to the advent of multi-core processors as they installed in ( most ) modern phones. Multi-core processors always have a "mixed speed": Not all cores are stressed the same way. Also, note how these multi-cores processors are designed: Octa-cores for example aren't using all 8 cores at once. Octa-cores use 4 high speed cores and 4 low speed power efficient cores. An Octa-core uses the 4 power efficient cores most of the time, but switches to the higher speed cores as needed for power intensive tasks.
I don't think there is a way to configure each cpu-core's max /min speed separately. BTW: Even today most Android apps/games make use of 2 cores only.
Hello,
I'm writing this thread to know which processor options would be optimal in our minis. The best settings, which give me the best performance/battery, I've found are:
CPU Governor: SMARTASSV2 (Default)
Min Freq: 19MHz
Max Freq: 748MHz
Undervolt: TRUE
I'm also using Apex Launcher. Which settings are you using?
Note: This are just my results, be careful when you change your processor settings.

Whats the purpose of Undervolting when you have it's max frequency as overclock?

Because it undervolts on every frequency below 600, and his minimum is 19, so when the phone is idle or doesn't need all of the processing power he saves battery
The SmartAss governor is very good at picking the right frequencies for any given job, so it doesn't allways run on 748Mhz, not even when you're using the phone.

That is the same very purpose of SMARTASSV2 to undervolt your device when idle or on sleepmode and overclocks it when on process. So ticking the undervolt wont affect your device because the one that manage the frequency will be the COUgovernor.

The SmartAss Governor only governs the frequencies, not the voltage that the Processor uses. there is a difference between the speed the cpu runs on (Mhz) and the amount of Electricity (Volts) it gets fed
Say Qualcomm has said it needs 5 volts to run at the stock frequency of 600Mhz, then the processor will always get 5 Volts, no matter which frequency it uses.
Undervolting will feed it less than the 5Volts when the frequencies are lower, SmartAss won't do that, it will run the 19Mhz still on 5Volts.
(Voltages are examples, i don't know the exact values, but I know that running on 122 or less will be stable on less than half of the nominal power)

nice to see some piece of truth over here (not perfect, but well explained)
de-noobing is good from time to time
xda is overcrowded of false answers given by people thinking they know but don't
anywhere, at anytime, newbies asking get fake answers from people wanting to help but failing to do so , due to lack of knowledge.
as everyone, i might be one of these, but try not to be.
make sure you know what you are talking about before spreading your (incomplete or false) knowledge
this was my thought of the day

Hey, thanks a lot for all the replies. I had no idea why my settings worked like i wanted.
Hi Guys,
Little question. Have somebody experience how much you can underclocking the CPU?
I asking because I want to save battery and I don't need the 2,5 ghz in my daily use.
But I heard that phone doesn't wake up if you I set the CPU frequency too low.
I am using Carbon Rom 5.1 and have root access.
PS: I have testing a little bit. My frequencies are working (using the App CPU Tuner and the recommended minimum frequency seems to be 300mhz. So I take this frequenz for my minimum).
PPS: So the thread can be deleted
A great way to reduce heat generated on the xperia 1 iii/5 iii also gain bit more battery life.
There was a debate on why the snapdragon 888 heats up and the 2 reasons most told was ''Samsung's manufacturing process'' and that the "GPU was overclocked to 800+ Mhz to excel in benchmark"
I reduced the GPU freq to 491 Mhz, I had top temp 45 Celsius, before it went past 50 Celsius . So in the end reduced a bit of CPU and GPU and got good battery life and way less hot.
First root phone.
Then install
3c cpu manager - Android Apps on Google Play
Enjoy millions of the latest Android apps, games, music, movies, TV, books, magazines & more. Anytime, anywhere, across your devices.
play.google.com
Any settings from this application is temporary, as you restart the phone the frequency are back to default, only change maximum freq nothing else don't change the governors.
My settings:
CPU 1: Max freq = 998 Mhz
CPU 2: Max Freq = 1.2 Mhz
CPU 3: Max Freq = 1.3 Mhz
GPU : Max Freq = 419 Mhz
Try and post the experience and if any improvement (Mention with region model numbers)
:-Since rooted might want to try call recording , great app. Since native sony doesn't support call recording in many regions.

Yes it wont stick, untill you flash modified kernel it doesn't stick but if you dont reboot it wont go. Also after setting the frequency, wait for the phone to sleep once then temperature stays to a max and for me the battery life increased, without any performance degrade.
Yeah the issue is there is no modified kernel out there for our device. Kirisakura kernel does not fully support our xperia 1 iii. Sony haven't released their source code.
Try the application and if you dont like to keep the application you can remove it, still it keeps the frequency you set, till you restart the device. Main for heating up in phone is the GPU, as per what i learned, reducing its frequency itself , reduced heat a lot. Try and let know your SOT and heat temperature avg.
Yeah i have EXkernel manager it indeed lessen the heat specially when gaming.
Kirisakura kernel supports our device now..
