Overclock kernel #31
Comments
你好,那个您可否方便发布一下安装方法? |
Hello, can you release the installation method conveniently? |
Because I found it didn't work when I installed it, I wrote the image on the MAC system. |
It seems there's a new tool and update here 👍 https://github.com/ophub/amlogic-s9xxx-armbian/tree/main/compile-kernel I am trying to follow these steps to create a kernel now.. old amlogic-armbian tree 👍 new tree 👍 Seems like kernel was compiled 👍
Building module: root@King:/usr/src/5.15.4# ls $ uname -a |
When Compile under the armbian system of your box. After the compilation is completed, the newly compiled kernel file will be cleaned up without changing the current system. |
I found the freq table here 👍 the missing freqs are added with patch from here |
// SPDX-License-Identifier: (GPL-2.0+ OR MIT)
#include "meson-g12b.dtsi" / {
}; |
Try to adjust and compile. |
https://browser.geekbench.com/v5/cpu/11129236 and before the modification: |
You can write a tutorial about your modification plan, and everyone can refer to it. You can customize the signature of the compiled kernel. If you want to share it, you can publish it. I will put it in the kernel library for friends who need it. |
i have uploaded the kernel here : https://vp5.net/king/ I also enabled 2.4Ghz support and 2Ghz on A53 cores, but I guess the -oc dtb file does not support those yet. |
uname -a I compiled latest ZEN kernel with Freq patches, you can get it from |
I am using Dell 2.5K monitor with native res of 2560x1440, screenshot with patches applied, kernel is uploaded to same dir as above (zen-pulp) |
linux-5.14.21.tjz is my patched kernel src. |
Thanks for sharing, I have recorded to armbian pioneer list. |
So, as we now have 2.2Ghz and its working properly.. I have extracted dts from gtking-oc.gtb, and here are freq settings:
and for A73 : ` opp-table-1 {
` |
CONVERT dtb to dtsdtc -I dtb -O dts /boot/dtb.img -o /boot/current.dts EDIT dtsnano /boot/current.dts CONVERT (BACK) dts to dtbdtc -I dts -O dtb /boot/current.dts -o /boot/dtb.img reboot |
So, i have rebuilt dtb file and it loads successfully |
I uploaded my modified dts and dtb file as gtking-current for now still the same : |
I also uploaded the kernel : -GT |
I found these new values from odroid n2+ dtb 👍
0xfde80 equals 1040000 :) |
We are getting somewhere 100000 250000 500000 667000 1000000 1200000 1398000 1512000 1608000 1704000 1800000 1908000 2016000 |
kernel : 5.15.5-low both files uploaded. As regulator does not support 1.4v , it is currently undervolted and overclocked. |
Yes, it feels snappier! |

Ok funny enough, i could overclock further . |
