Underclock or undervolt cpu - Huawei P20 Questions & Answers

Hello guys
How do we undervolt or underclock the cpu on the p20?
Another question ive noticed that the min freq for the Kirin 970 is 500mhz. Correct?

Which cpu freq are best?

Xperia X10 mini pro [MOD] FroyoComb v1.2
What is the best cpu frequency for stabile working, i use set cpu app for this.
I use 'coservative' scalling Min: 768 Mhz (when some problems i reduce to 748MHZ or 600Mhz when i dont need more performance) Max: 787 MHz or even 808 Mhz but this freq is too high. Is this scalling are good or use different (ondemand,performance)
Also i have question when my phone is blocked (screen is off) cpu freq back to normal low freq or still have the same freq like in set cpu app ?
No one can give specifics as even with one model of phone the quality of CPU changes so set frequencies differ.
EG: i'm using DHD with 1.6GHz OC "smartass" but some users top out on 1.3GHz, could OC more stable but don't need, regards underclock i've screen off "Powersave" lowest frequency 245MHz don't forget to set priority high.
There is more you can do with set CPU such as underclock on less battery so know get more for criticle phone usage, also temp based so again saving power.
Anyway best bet is to look for other users of x10 and see what they top etc.

M9701 - Allwinner A10 max cpu speed is 1008Mhz

Hi,
I have a baili-mostlike.com/product/22.html M9701 and all over the internet and even in system info apps say that the max cpu speed is 1.2Ghz. I installed setcpu and voltage control and both have the max cpu speed to 1.2ghz but looking at the historical cpu speed state it never reach the 1.2Ghz and the max is 1008mhz.
How can I increase it?
Thanks

[Q] Help with setting up kernel please.

I am having trouble regarding these: undervolt
maximum cpu frequency
maximum gpu frequency
cpu thermal throttling
So i downloaded kernel :Sultan-kernel-Pure-v1.7.0-Pyramid-Aroma.zip
6.5MB, which I think is the latest one. But i am not familiar with those because it is my frist time to flash my own rom and kernel. I've done everything right but can you help me set up the kernel? which is best? because there are numbers in it and i dont know what to choose. Also what is best setting for saving battery life? overclock, underclock, undervolt, cpu freq, gpu freq, thermal throttling., what are those
I also apologize for posting like 3 threads for this because im a newbie. I hope you consider. HELP me please.

for good battery life put these settings:
cpu freq: whatever freq you want but maximum at 1.5ghz
gpu freq:266mhz
undervolt:whatever value you want but maximum -50mv

Tnx. I did what you said. Hopefully it'll help with battery life.

[Q] Can some provide us with some advanced Geekbench 3 results?

You need root for this and probably need a way to disable the CPU clusters.
What is the Geekbench 3 results for the following?
Only A53 cluster with performance gov (locked 1.5 ghz)
Only A57 cluster with performance gov (locked 2.1 ghz)
You need to monitor CPU utilization in order to know that only the wanted CPU cluster is being used.
Core 1 - 4 is A53 cluster
Core 5 - 8 is A57 cluster
EDIT: when running Geekbench 3 normally, can someone check if all cores 1-8 are used by Geekbench 3 for the multicore result by monitoring utilization of all 8 cores during the benchmark. If all 8 cores are used there should be vey high % utilization on all 8 cores during some parts of the benchmark.
Thank you.

Why?
Short version
I'm interested in the CPU performance of both clusters separately because I manage my phone performance (Note 3) with the help of
Multicore CPU Control PRO, and SetCpu with profiles enabled on screen off/on and certain applications.
I don't find the stock settings responsive and smooth enough so I adjust them.

Why is cpu frequency only 1.3Ghz?

I'm using stock emui on android 4.4.2. I recently rooted my phone and noticed that the cpu frequencies are really weird. First of all all cpu over/underclocking apps showed max of 1.3 Ghz and min of 1.2 Ghz. Shouldn't max be 1.7 Ghz? Even more weird was i couldn't change the frequencies to anything else. I wanted to reduce the heat that 1.2 Ghz min frequency causes and thats why I rooted in first place. I managed to get frequencies stay by using Trickster mod's freq lock. But I'm still wondering if its normal for my phone to get hot and can I set max freq to 7.8 Ghz for gaming? And no, the power saving thing aka phone manager doesn't change anything else but increase battery life when I disable it.
That's for the A7 cluster. A15 cluster goes up to 1,7 GHz.

I just noticed in another cpu tweaking app that it showed only some of cores can go up to 1.7 Ghz and other only to 1.3 Ghz. This furthermore confirms it that only half of cores are cabable of 1.7 Ghz. http://www.devicespecifications.com/en/model-cpu/6dee2d53
Too bad this info isn't almost anywhere at all.
