[Q] Add custom CPU Frequencies to Kernel - Nexus 7 (2013) Q&A

Hi there
Is there any solution to add custom CPU frequencies to the kernel?
As the ElementalX Q port is locked up to 1512Mhz
I remember the original version can push up to 1.9Ghz something
Any solutions?

BUMP
we really need it, For good work on a12.1
But here you only need a custom kernel with a set of these frequencies. No way to add on your own (
also it would be nice to increase the frequency of the GPU

GPU can be overclocked to 550mhz. Just CPU is locked down. pity!

[Q] Overclocking GPU?

Hi,
Sorry if this has been posted before but I can't find an answer to this question
I am currently running AOKP and trinity kernel, 1344mhz (cpu) and 499mhz (gpu). After installing the kernel, I manually went into ROM control, and increased the CPU to 1344mhz - set on boot. That was the CPU overclocked
However, I can't figure out how to overclock the GPU? I have run a benchmark, and it seems to still be at stock, and not 499mhz - how do I set it to the 499mhz that the kernel allows?
Thanks

There is a command that you can run from terminal on your phone but I can't think of it right now. Also, a bit of searching seems that there is an app. I haven't tested to see if it works, but it says it OCs the CPU AND GPU. Look for Overclocking(GPU + CPU) in google.

That one apparently doesn't work.. have also tried Antutu CPU Master pro but it doesn't support GPU overclocking on the Galaxy Nexus...
Afaik, gpu oc is only available, if built-in the kernel. Userland controlled gpu oc must be supported by the kernel first, thats probably why antutu pro master or any other app still can't do it.

System or Kernel chages cpu frequencies itself!!?

Hey guys,
i got a problem adjusting the cpu frequencies on my Galaxy S4 mini GT9195.
For example, i change it to 162mhz minimum and 1026mhz maximum and the smartassV2 govenor. Then that changes ramdomly to some weird frequencies automaticly and out of a sudden. Like 1458mhz minimum and maximum.
I use the cyanogenmod11 M7 rom and the f4ktion 1.5.0 Kernel (the cyanogen kernel does the same btw)
As App for adjusting i use the Kernel Tweaker, but even if i do it in the System settings its doing the same...
I did some undervolting, this stays as i set it.
I hope you guys can help me its annoying to check it every houre and see that it changed again and drains my battery

Devices using a modern qualcomm cpu, relies on two userspace daemons (mpdecision and thermald) to manage frequency and thermal throttling. So mpdecision takes care of the frequencies and cpu hot-plugging (when to engage additional cores or not), and thermald lowers the frequency if the temperature gets too high, in order to protect the cpu from overheating. This is not compatible with the frequency settings in CM or any third party app with similar functionality, as they will always override whatever you set there.

I see.. Thanks for the answer mate, so there's no way to save battery like this? It just seems sometimes that it's stuck at some frequencies...
Well, you could make a custom boot image that disables those daemons, but it could cause more harm than good.

f4ktion kernel 1.5.0 is not designed for M7. For M7 use 1.4.5.
I'm right now with nightly 0703, kernel 1.5.0, mpdecision disable and MSM Hotplug enable (performance control). With this settings that bug disapeared. 162 mhz - 1728 mhz; smartassh3; ROW.
In M7, and 1.4.5 kernel, the only governor that works with 162 mhz and don't change to 1458 mhz is the Ondemand.

[LG D855] CPU Frequency doesn't stick

Why doesn't the max cpu remain constant in kernel audiutor??
I have cm 13 and I have tried flashing the Nebula kernel, used their modded kernel audiutor app and max frequency doesn't stick, after I put it at 2457 MHz and try out a benchmark I would get sh**ty scores and go back to Kernel Audiutor app to find out that my new max frequency was 800 MHz (or another, max frequency was totally random) , why??? I tried flashing the 777 Kernel (maybe the kernel was the issue?) and got the same result! Cpu frequency changes after a while, am I doing something wrong? I have disabled hotplug cpu and the thermal to see if it was the case, didnt work... Any solution?
Settings > Battery > Set mode to performance - you can set this in kernel audiutor i believe (sorry my spelling is crap) but i'm not sure what section it's in.
Still doesn't work
I just tried your suggestion after a little bit of googling and finding this thread. What else could I try? I see my CPU change instantly after applying the changes ..... My phone is really lagging so that's why I need to change this stupid setting.

You can use any custom overclocked kernel from forum and set cpu clocking frequency to stock i.e 2.1 ghz and overclock gpu frequency as per your need using kernel adiutor app. You may find app link on custom kernel thread page.

but that degraded my overall performance and increased heating:crying::crying:

Over clocking will always produce more heating. Usually Custom Kernel which allows OC comes with tweaks to thermal management to counter that as much as possible.

Question POCO F3 CPU min/max frequencies constantly changing by themselves

This is my first post on XDA. Recently, I got a POCO F3. Today, I tried various combinations of mods and custom firmwares and when I check in Franco Kernel Manager, my CPU min and max frequencies are chaging bby themselves. This is just with root and custom recovery installed. I thought a custom kernel may fix this, but it didn't (I tried Immensity-X, WildAngel Performance and NoGravity). As well as that, I'm finding that the GPU cannot handle an overclock or else the min and max frequencies will also fluctuate by themselves. The overclock I tried was to 682 MHz (my F3 isn't a silicon lottery winner). Does anyone have any idea as to what the issue might be?
you try flash last build NoGravity Kernel v1.0.1 + NGK App 6.1.1 (Hotfix) ?

Xiaomi does some crazy ass throttlings that limits cpu freq to 2.7k default and keeps changing with temperature 37*c, 39*c, 41*c and so on
same with gpu, gpu is not limited but it starts throttling at higher temperatures too but the problem with gpu throttling is that it doesnt revert back to highest when the temperature cools down, you'll have to revert it manually.
only way to fix this is if you edit the thermals yourself or use dynamic profile or flash thermal no junk

You can fix the freq. of both CPU and GPU to be max, and disable the mi_thermald. Try "extras/jitter-reducer.sh" in USB_SampleRate_Changer which has been developed for hi-fi audio use. But this can disable almost possible battery saving features, e.g., GPU power level, thermal throttling, doze, wireless connectivity optimization, etc., to avoid jitter distortion on all digital audio outputs.
Note: this is tested only on the STOCK kernel.
