Since i've installed the new rom release 502 seems that CPU Z is reporting all cores to be stuck at a minimum of 800mhz per core. I could have tried in the past to change to noop and interact with CPU adjust. Now it doesnt work, i want the cores to sleep and keep one of them to 200mhz when full idle.
Any suggestions?

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.
Hello!
as I finaly rooted my TF (after a year of stock ) I have already hit few obstacles while making it perfect. Now i have a question regarding overclocking.
My device: ARHD Rom with guevors kernel 21.4
I use my TF at 1,6ghz via SetCPU. In CPUStats it says it doesnt use 1,4ghz and 1.5ghz freqs at all as the time at those freqs is zero. But when I clock it up to 1.4 or 1.5, it does use them (note: when set to 1.5ghz, 1.4ghz freq is still not used). What could be the reason for that?
Thank you for your answers

Looking at cpu histories it usually defaults to the lower stuff except when you do complex calculations, in which it uses as much as it can until it's done. That's why it doesn't use those middle freqs as much, if that makes any sense.
I agree with Thing o Doom. A lot depends on what the processor/software decides it needs or wants.
I stopped using a wide range of frequency like 216-1200 and stuck with a straight 1200MHz only on the min and max.
Depending on the CPU load will determine whether it even hits a certain frequency and also based on the type of governor.
If you have a governor that is set for performance and your range is 1400 - 1600, the governor interacts with the rest of the system and may ramp straight up to 1600 without every hitting 1500.
Hope that expands on Doom's answer.
I use interactive gov. and usualy cpu clocks scale at every cpu freq described in kernels scaling. I use 216-1400 now and cpu uses all clocks in that range (depends on the need ofc). But if i use 216-1600 then not all of the freqs are used. I meant to say if u scale it to 216-1600 there should be some point where cpu would use 1400mhz freq, but mine doesnt at all. So the scaling goes from 1200 directly to 1600 and no in between resulting the cpu to be more time at higher clocks when not actualy needed (when it could just use 1400 or 1500mhz).
Anyway, i now use scale of 216-1400mhz and seems to be working great dunno why I even bothered with 1600, but this one thing not scaling at those two freqs did scare me as I thought there is smth wrong with my tf
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.
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.
My Lenovo tablet (TB-J716F) has an issue with its clockrates. It refuses to clock the Snapdragon 870 CPU cores over 1ghz and the Adreno-GPU stays at 300mhz locked, even tho temperatures do not exceed 40C, unless it detects that a benchmark is running. I found something to manually adjust CPU clocks on my rooted device. Is there such a thing for the GPU?
Any help would be greatly appreciated!
