Battery is dead after 4 hours of gaming/browsing or standby?? Use Performance Control to set up the kernel right Android 4+ uses virtual ram taht may slow down the performance. Set swappiness in vm settings to 30. Keep in mind that zRam should be not more than 25% of the physical ram. Set sdcard read value to 512kb or 2048kb. Try different combinations of scheduler/governour. Don't overclock the cpu/gpu if the device already becomes hot.
In many cases the presetted kernel config is just kinda crappy and you can gain a lot by matching it to your needs

[Q] Having some trouble overclocking gpu

Hi, I am running slimbean 4.3.1 and the blackhawk kernel on my p5113. I have successfully oc'd the CPU (its in the settings so it was easy). However, I don't see where I can set the GPU to a certain frequency. I have done a lot of searching, but without results.
Could someone please help me out with this? Thanks!

brother you can only overclock cpu not gpu
only what you can do regarding gpu is that you can check force gpu rendering settings in developer options

I disagree with you partially, you can oc gpu too. You can do it by changing manually which i did last time months ago because i have been using TricksterMOD, but it seems like after 2.1.5(?) update to kernel you can't do it anymore with it, so i use older version of next kernel what op is using.
EDIT: Actually i solved the problems and now it works with latest version using TricksterMOD!
Btw im on Cm 10.2 as you can see.

Best performance on HTC PICO

Hi. How get maximum performance on Pico? I mean fastest ROM and OC kernel (safe, with partition sdcard). I want Cm 10.x and @878MHz (this no needed, i only like ant want it but if you have something with better performance, i will get it )
Don't Compare ROMS!
No offense but, You don't ask which rom is better. I've seen many threads closed due to that kind of question. Developers try very hard to develop a stable rom for our pico & all you do is ask about only the best one without even giving others a try..you should try & decide yourself, it's not that difficult..anyways, using pll2 overclock kernel boosts the performance..there's no other way to improve performance that much.
But some roms is faster and some slower. Some kernels (with pll2 overclocking) giving more performance. I'm asking with which rom and which kernel i will get highest performance. I'm not asking which rom is better
Example:
minimilised rom is faster than unofficial cm 10.2 . Aries kernel on 844MHz giving more performance than pandora @878MHz.
You understand me?

Kernels, must have a ROM ?

So, do you need a specific ROM for specific kernels? Or can you download kernels without a ROM?

If possible to download kernels, can someone link me to a list of them if that's how it works.

I know I am sounding like a total noob right now, I've flashed ROMs many times but don't know much about kernels
@jongonzalez716705
Of course you can flash a kernel without a rom.
Make sure that the kernel is compatible with your current rom.
Profits about a kernel;
+ Some kernels let your overlock your processors
+ faster boot time
+ some kernels have some other advantages.
Which phone do you have?

I currently have a Samsung Galaxy S 5 SM-G900T. I'm currently running XtreStolite ROM but currently running through some issues like wallpaper picker keeps force closing when I choose one, Setup for Fingerprint says to restart, I do, and still nothing, and tried downloading MyFiles but when ever I do an action, it force closes.

I know but I've downloaded a ROM before that had its own custom kernel. Had fun overclocking but spent more time underclocking. Is there somewhere where I can download certain kernels?
Yes,you can flash Kernels.
Why are custom kernels android useful?
Ans:Kernels are the brain of your Android device and communicate between software and hardware. Therefore, they are responsible for managing things like CPU / GPU clocking speed, screen sensitivity / colors or voltage. By using a custom kernel you can not only improve battery life, but also increase system performance.
Many custom ROMs already come with their own kernels. This is done to implement software communication of the custom ROM with the hardware of the device and also to ensure a better performance. Nevertheless, you are often also able to flash custom kernels to custom ROMs. If you decided to stick to a rooted version of stock Android, flashing a new kernel can offer you additional performance with the convenience of a stock OS.
Always make sure to check compatibility of the kernel with your ROM and device, because flashing a wrong kernel can brick your phone!
You can use this apk called as Franco.kernel. The app is available in playstore.

[KERNEL][NOUGAT] AKLU Kernel

Praise God! The AKLU kernel has arrived on the Galaxy Note Edge in the flavor of NOUGAT!
NOTE: I highly recommend turning off THERMAL CORE CONTROL! Use THERMAL TEMPERATURE THROTTLE instead. Thermal core control has been known to cause random reboots on this kernel before when gaming or during heavy use. You can use Kernel Adiutor to adjust these settings.
TBLTE AKLU KERNEL for AOKP 7.1.2!
MAY work for other LineageOS based roms, e.g., RR, PAC,AOKP, LineageOS, etc.
Download:
http://www.mediafire.com/file/pcownjeat1o2oub/AKLU-TBLTE-AOKP-N-20170427_kexec.zip
TBLTE AKLU KERNEL for SLIM 7.1.1!
MAY work for other AOSP based roms, e.g., OmniRom, LiquidDark, SlimRoms, AOSP, etc.
Download:
http://www.mediafire.com/file/cl0ahc00zmxcai2/AKLU-TBLTE-SLIM-N-20170224.zip
Logs and features:
Modified TBLTE kernel. Modified by the Alaskalinuxuser.
https://thealaskalinuxuser.wordpress.com
20170427
- Updated kernel to include kexec hardboot for MultiRom support.
20170316
-Update for OMS support.
20170217
- Fix WiFi hot spot error for Nougat.
- Overclocked the GPU from 600MHz to 633MHz
- Overclocked the CPU from 2649MHz to 2688MHz
- Added governors: Bioshock, Lionheart, Nightmare, Darkness
- Removed input boost, use cpu boost instead
- Added I/O schedulers: FIOPS, ZEN
I haven't loaded up AOKP yet but this kernel is working beautifully with RR and the data fix. You rock man.

In theory it should work with any nougat rom based on LineageOS, but I have not proved that personally. Thanks for confirming that for RR and providing the feedback!

Thanks for the thought, but I do not accept donations. I just tinker for fun, and have my own rewards. Besides, guys like @Mickey387 did all the heavy lifting, I just try to put the device trees and vendor blobs to good use, with a few edits here and there. Glad to know that my work is appreciated, though.
The slim 7 aklu kernel appears to be slightly unstable at this time. Please use with caution.
EDIT: Updated the kernel and fixed a few bugs that I missed in the first build. SHOULD be better now. Please turn off thermal core control for best performance!
Also, if you flashed superSU in Slim to root it, you need to flash the kernel, then immidiately flash superSU, then reboot.

I have noticed that many of these processors on the note4/edge are of a good bin.. Mine can run about 45mv off from stock..

Thanks afbcamero, those are kind words.
On my MM kernels I did implement UV, but the way I did it in MM fails to pass in the N kernel. Not because it doesn't work, but rather that new build standards don't allow it. With the recent birth of my son, I have not had time yet to go back to it and figure out what was wrong yet. Are you familiar with kernel work? You could look at my github and my kernel source, perhaps you could show me where I went wrong?
If I can get passed that, I can implement the UV again. I also have the same problem for GPU voltage control, which I used to put on my MM kernels as well.
Perhaps when life slows down a bit, I can look back into it.

Oh I see, i honestly never looked at the structure of Nougat kernels. Any time I want to implement a change somebody does it better and beats me to the punch.. I will look at it just in case I see something..
On another note, these things however fun (development) not being trully important, may your family be blessed by the big guy.
Thanks! I'm always open to ideas on kernel improvement.

Should I update from CM13

It's been a solid year since I've updated my tab 10.1's rom, and it's slowed down a bit (mainly because of RAM), so I wanted to ask the community should I update from CM13?
I'm looking for a rom with these qualities:

- Themes
- Fast and light
- Can be OC'd
- Compatible w/ Xposed

There is no working OC Kernel anymore.
You can use some 2 years old device specific builds with old OC Kernel only.
UA doesn't have a theme manager - it's almost pure AOSP and won't have any extras added in future (maybe an integrated Updater only).
