PowerGaming by Snapdragon teaks


Assuming you have a custom recovery installed, simply download and flash the kernel zip. This kernel uses Anykernel 3 so no need to reflash magisk(if you use magisk) after installing it.

for Samsung Galaxy Note 9/S9/S9 plus Snapdragon only!

Introducing the POWERGAMING KERNEL for Samsung galaxy S9+/S9/N9!

Hello, Samsung SDM845! We're excited to bring you the latest development in enhancing your Android device experience - the POWERGAMING KERNEL, crafted by the talented @Elchanz3. This kernel introduces a range of optimizations and improvements to elevate your device's performance and efficiency.

Key Features:

GPU Overclocking: Experience a boost in graphical performance with stable GPU overclocking up to 820MHz.

GPU Underclocking: During idle moments, the GPU is smartly underclocked to 150MHz, conserving power without compromising performance.

GPU Undervoltage: Enjoy enhanced power efficiency with a significant 40mV reduction in GPU voltage.

Memory Power Savings: The kernel employs intelligent memory power-saving mechanisms, ensuring optimal performance during idle periods.

CPU Governors: Discover a variety of renowned CPU governors, incorporating a modded Schedutil by @Elchanz22 for seamless performance management.

I/O Schedulers: Seven new I/O schedulers are introduced, with Zen as the default, to enhance data handling and responsiveness.

Boot Time Optimization: Special bootloader command line arguments are integrated to minimize boot time and get you up and running faster.

Adreno Boost and Idler: Enjoy optimized Adreno GPU performance and power efficiency for extended battery life.

Thermal Modifications: The kernel incorporates thermal tweaks for effective device temperature management.

USB Fast Charging: Experience rapid charging capabilities with integrated USB fast charging support.

File System Support: Support for sdFAT file systems is now available, enhancing compatibility and data management.

Memory Management: Benefit from advanced memory management with ZRAM, vnswap, and zswap support.

Customization: Take control with additional features such as vibrator intensity control, LED management, and a devfreq boost driver.

Enhanced User Experience: The POWERGAMING KERNEL offers a comprehensive array of enhancements, placing a strong focus on performance, power efficiency, and customization options.

For detailed installation instructions and to access the latest updates, join our Kernel Channel and our dedicated Questions and Bug Reports Group.

Don't miss out on the opportunity to elevate your Android device's capabilities with the POWERGAMING KERNEL. Experience smoother performance, improved battery life, and a customizable device experience like never before!

To get started, simply follow the installation steps, and remember to restart your device to apply these exciting changes.

Kernel Source

Kernel Features:


PGK 1.0.7 changes:

Fixed both camera & NFC for OneUI

GPU Underclock to 150MHz

introduced wiregard vpn

kernel upstream to 4.9.200

significant storage driver optimizations

several changes under the hood

PGK v1.0.5 chages:

-introduce devfreq booster driver

-thermal mods

-re made GPU freq table based in SD888

-increase GPU voltages to be more stable

-converted some subsystems for performance

-GPU driver optmizations

-USB fast charging (enabled by default)

-Improve performance critical IRQ framework

-introduce boeffla_wl_blocker v1.1.0!

-CPU idle optmizations

-use BBR as default TCP Congest

-re-write CPU Hotplug for better performance

-Mark important kthreads as performance critical

-introduce CPU input boost

-clk-cpu-osm: Convert atomic delay into sleep

-mm: Boost when memory pressure becomes high

-disable a lot of debugs

-schedtune: Add boost retention to RT

-cpu-input-boost: Boost DDR Bus also on input boost


Klimbo v2.4 (OLD)

-kernel based on USA source FVB2

-add various optimization

-compiled with GCC linaro 6.5

-UC GPU up to 133MHz to save power

-GPU OC to 840MHz stable

-GPU uV -30mV

-reworked gpu frequency table for better performance


make a backup of the "boot" partition in your twrp/orangefox if you want to undo the oc (overclock).

because it is a USA version, your img is recognized as such, thus imposing.


use at your own risk, I am not responsible for the misuse of the kernel and major damage

For more informations and more builds :


Klimbo V1.0:
Linux 4.9.206

First relase Klimbo v1.0 for 9 series!

-added adreno boost (Mid boost enabled by default)

-Various optimizations and source code fixes for cleaner code

-slimbus OC

-Overclock SDM845 audio chip 25x192 > 48MHz (this grants 18x better audio quality)

-Schedutil tuned for better performance.

thats all for now. new update coming soon!

Hello I have the SM-N960u (ATT Note9 snapdragon) bootloader unlocked and rooted. I tried installing your kernel via recpvery. But got an error saying unsupported device. I understand not many folks have this phone unlock. Is there anyway I can get it to work?

hi, my kernel is for CHN variants only.. so USA models will not proceed instalation
