[Q] Change Default CPU Speed On Boot Permanently - CM7

Like the title says, I was just wondering if there was a way to change the default CPU speed on boot permanently? I know I can use SetCPU, but sometimes that hasn't held through a boot and I had to set the speed manually. So, I was hoping there was just some script somewhere I would have to change. But then I got to wondering, would that be possible from my phone? Would I have to build my own kernel? Or would I just be able to decompile the rom in dsixda's kitchen to change a kernel script? Any help is greatly appreciated!

I use ROM Toolbox. It has a ton of stuff including CPU Control and CPU Profiles (like to make it 691MHz max when the screen is off). And you get a lot of other stuff with ROM Toolbox. But you could say the CPU part is like Set CPU. Don't really know if this answered your question. Hope I helped though.

I'm pretty sure CM7 has a built in CPU setting feature in its Cyanogenmod Settings -> Performance menu. It gives you the option to set on boot as well. I've never played around with it so I'm not sure if it'll give you the same problems you're describing now, but it's worth a shot if you don't want the separate app.

Is your phone rooted?

[Q] System Tuner Settings

You can search all you want and still come up short, I'm trying to use system tuner to change the cpu and gpu settings and I cant find any help on how to use this app. Im running the latest Kaos Droid rom for 4.1.2, the latest Motley kernel and twrp, props to all developers:good:. Im looking for what the optimal settings are and how to use system tuner to change them. Can someone tell me or show me the right thread that can help? Im not sure what the min/max cpu settings should be and I cant seem to find where to change the gpu settings. We are all noobs at some point. I just want to beef my nexus up a little, nothing crazy.

aww for real?

I wouldn't use system tuner for this because it doesn't have the ability to change the GPU speed. I'd recommend TricksterMOD which is available here for free. Depending on your kernel (not sure if motley's kernel has configurable GPU now, it didn't when I used it) you can change different settings. It is personally up to you how you want to configure your device and change things depending on how it runs. Anyway, I'll give you an idea of my settings that I have changed.
CPU - Governor is Interactive (my kernels default but another alternative would be ondemand) running @ 102mhz min - 1600mhz max
IO - Governor is deadline (again default but imo the only one you should use) with cache at 1024.
GPU - 600mhz
VOLTAGES - My kernels defaults.
Make sure that you set the settings to be applied at boot (I use a delay of 1 because it didn't seem to apply without it) and also make sure your kernel has the powerHAL fix included, or else (in the case of trinity kernel) you will need to download this file (this is for Android 4.2.x). This will allow your CPU overclock to stick and not be reset to stock.
Hopefully this helps! But again, just play around with your frequency's and maybe look into voltage tweaking to get your personal balance between performance and power consumption. And if you are going for performance, I'd look at turning off fsync and using the ext4 mount script to boost your I/O dramatically (this will result in things such as faster app installs)

Nexus 4: Best ROM To Use As A Media Player?

Hi guys,
I own an Nexus 4 with parts of the screen not responding. I got a new phone now (Ecoo E04 Plus), now I want to build a iPod-alternative. Now to my question, whats the best ROM for that purpose? It needs a long battery life in airplane mode. Second question anyone nows an that changes ur homescreen to a nice media player? (I thought of Themer) And my third question is what kernel would you prefer? Thanks for your help.

PS: Sry for my bad english, I'm only english basic course.

i would suggest stock rom with a few mods or a custom rom. the important thing is custom kernel.
the way i would do it is:
1. stock with xposed framework+gravity box. that way you can enable volume keys to change track
2. chroma rom. ia currently use chroma rom an it is rock stable and it has tweaks built in one of them is volume keys to change track.
in both cases i would install a custom kernel f.e. franco kernel for better battery life. if you want to maximize the battery life you can undervolt/underclock/disable cores. my phone is always undervolted 150mV.
my advice is undervolt (undervolting to much will reboot your phone. my cpu undervolt limit is 150mV so keep that in mind)and disable two cores. two cores are already capable to handle everything. the cpu frequency should be 384mhz - 1.3ghz or 1.5 ghz. see what is good for you. know that the higher the mhz the more power you need
also remember to disable sync and, if you don't need, don't install google services for battery again.
for maximizing battery i don't know which android version is best. i would go to android 4.4.4 or 5.1.1
for home screen i would suggest a widget. also you can also make your player start automatically when android start. there a lot of app in playstore for that.
P.S. if you encourter any stuttering during music playback one reason could be the low frequency of the cpu. i had a problem like this some time ago that is no more on android5.1.1. the solution for me was to change the lower cpu frequency to 512mhz or 700mhz. this solved my problem.
P.S.2 for changing the kernel setting i use franco kernel app. it is a paid app and simple to use. the free franco kernel will flash the appropriate kernel for you. you can find a lot of apps in the store that are free one populare is synapse if i remember correctly.
if you need anything else feel free to ask. hope i helped

Increasing Performance

My phone is unrooted & my games (well one game need for speed no limits) lags after about 5 minutes of play; what can I do to remedy this?

I think if u want have a smooth rom
Root + delete some system app needen't
And try app kernel audiutor set cpu performance mode,

Phone slow after root

I rooted and am running tek s ROM. The phone has been super laggy and slow since I flashed that ROM. Any advice.

Have you switched the governor to interactive or on-demand? That's the most important piece. The below link has a bunch of tips (universal to qualcomm/US S7 and S7e) to improve performance.

Check the thread under Guides about common problems and fixes.

I did but I didn't see a fix for this. I did what another member told me to do and it worked.

Bug #1: Phone is laggy after rooting the phone/Battery is down the tank.
Fix: The phone is (partially) lagging because the ENG bootloader automatically sets the CPU governor to "Performance." While this is supposed to lock the CPU frequency at the maximum values, it does cause a lot of heat and possibly throttling. Additionally, the max core clocks are set to 1.593Ghz instead of their actual maximums. Not every CPU Tuner will allow you to set the big cores separately, so look around for one that does if you don't want to use Kernel Toolkit.
First, use Flashify to flash one of two zips provided by psouza4 on our sister Verizon Galaxy S7 (Edge) threads.
1. Kernel fixes & tweaks V15
2. Kernel fixes, tweaks, & Debloater
You need only flash one of these two zips. One additionally debloats the system, one does not. Choose whichever suits your needs.
What the zips do:

Next, install a CPU Tuner utility like Kernel Toolkit, then change the governor from "Performance" to "Interactive." Also change the max CPU frequency of the little cores to 1.593Ghz and the big cores to 2.150Ghz while you're at it. Leave the cores at their default minimum frequency. This will go a long way to improving the speed of the phone. Also make sure you that have the new settings to apply on boot. Every kernel manager should have this option somewhere.
Note: Although the max frequency in the settings screen will drop to some number, as long as you can see the CPU ramp up to the new settings in the information screen, then everything is fine. You can test the max frequency by turning the screen off and then back on.
Then, install sEFix and set entropy to "Ultra."
Lastly, install L Speed and:
Code:
-Main Tweaks: Turn on
-Battery Improvement
-OOM Killer
-Kernel Tweaks - "Light"
-CPU Tuner: Turn on
-CPU Optimizer
-LNET Optimizer: Turn on
-Google DNS
-Faster Streaming
-Faster Dormancy
-IO Tweaks: Turn on
-IO Boost
-Partition Remount
-RAM Manager
-Balanced
-Seeder
-Moderate
Literally the first bug and fix on the guide.
