[Q] A question about overclocking the x8.

Hi, im having some problems with overclocking my phone.
Im using doixanh guide called "[Module] X8Overclock | v004 - Multiple freq | X8 | X10 mini | X10 mini pro | 11-04-11".
when I add the code
Code:
"insmod /system/lib/modules/x8oc.ko # x8 overclock"
in the file hw_config.sh and then push it back in the phone and then restart it, the phone is overclocked 110 MHz. And when i put
Code:
# x8 overclock
insmod /system/lib/modules/x8oc.ko
sleep 2
echo xAB > /proc/x8oc
the MHz wont change even if i write "echo x27/28 and higher. He wrote in his guide that u can change the freq. from 614MHz to 826MHz but it wont work for me, so how do i get it to work. Thanks for help and sorry for my bad english!
in v004, change frequency with setcpu or similar. enable "set on boot" option and remove echo xAB line. it should work that way.
also, you might want to insmod in chargemon instead of hw_config because it's executed at beginning of boot sequence.

You should also be able to set the CPU min/man frequencies and governor at the CM Performance settings menu.

Sorry for hijacking the thread but i didnt wanna start another about X8 OC. nobodyAtall posted this in the miniCM thread. Set Cpu worked for me but I dont see anything when i open the min/max freq in CM Performance settings. Just the "cancel" and nothing else. Just like before the X8oc.ko push
try to download the newest x8oc.ko do as the instruction. install setcpu and reboot. i do it in MiniCM and now i apply it on stock ROM. it works. setcpu shows that i have max freq : 825,6 MHZ and Min Freq : 122,88 Mhz. i run ae 748 (ondemand) and still good in stock ROM.

[Q] Defy+ Moto Ice Gun Edition V.1.0 won't overclock??!

I have problems with the CPU settings:
1) Bootloader: 300/20 700/40 1200/60, governor " boosted "
2) On the rom the max frequency is shown as 1000 and the governor is " ondemand "
3) I turn on setVsel my phone reboot,
4) I then use CPU SPY and it reads 300/33 600/48 1000/58 with " ondemand " governor
I tried to fix permissions but i had no success in getting the same values both in the bootloader and in the rom itself ...
thanks in advance
Defy+ Moto Ice Gun Edition V.1.0

Complete LG G3 CAT 6 F460 Tweaks and Recoveries

For all F460 variants recovery can be downloaded from here https://drive.google.com/file/d/0B4A...ew?usp=sharing this is for who having Lollipop v20c not kitkat.
The above recovery is a permanent recovery which is CWM(Clock Work Mod) recovery.
If you want touch enabled TWRP recovery flash this zip from the CWM recovery https://drive.google.com/file/d/0BwN...ew?usp=sharing
Our stock firmware locked with 389 GPU speed to unlock to 600mhz max GPU speed. Flash the below thermal mod which i modified it will boost up the CPU AND GPU Performance as well as Battery. This thermal mod makes the CPU and GPU locked at stable frequencies.
https://drive.google.com/file/d/0BwN...ew?usp=sharing
If you want further tweaks download L speed v2.2 from the below link and flash this zip file from recovery
https://drive.google.com/folder/d/0B...F0WVdsOHc/edit
But to make this work first you need to enable the init.d support, terminal emulator, root explorer and busybox.
Refer this link how to enable init.d support for rooted devices http://forum.xda-developers.com/show....php?t=1710980
After you enabled init.d
Flash the L speed v2.2 zip file from recovery and
Open Terminal emulator app and type (case sensitive)
su
boost
If you want to go LSpeed wizard type
su
LS
Where you can find alot of options unser LS Wizard to tune your android device. Like cpu tuner, Ram management, Seeder, Cleaner, Buil.prop tweaks. CPU governor tweaks, Zip align, VM tweaks, Net tweaks, Io tweaks, SD tweaks, Kernel tweaks etc., Our LG G3 supports all of them(Lucky atleast here)
If you want to increase the performance to MAXIMUM further you can download any Kernel control app like Device control, Trickster mod Kernel tweak from playstore and put the cpu governor in CONSERVATIVE mode and Read head buffer size 1024kb. That's it.
Credits to Robshr, JZ shimer, Lam Haong, Paget96
Update: Found that mobile performs smooth and less heat when setting up the CPU frequency min 300 and max 1574 and CPU governor in conservative mode.
Putting Batter Saver ON will reduce the heat produced by the screen.
Hit thanks if i helped you. All the best :good:
all of your links are dead bro

[OOS] [ROOT] Increase performance in Oxygen OS without flashing a custom kernel

This is a very simple guide to increase performance in Oxygen os (any version) for those of you who are sick of the lagfest sometimes experienced in OOS (i know i am). Many people just flash a custom kernel, which is a good way to fix performance. For those of you who dont want to mess around with flashing kernels (and are rooted), just download kernel adiutor (https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=pt_PT) from play store and edit the values to these ones:
- Open kernel adiutor, give it root access, and go into cpu section and do the following changes:
Change MAX cpu freq to 1958Mhz.
Scroll down to the end and change input boost from 960Mhz to 1497Mhz.
Make sure interactive governor is selected and go into governor settings.
Change the following parameters:
Above_hispeed_delay: 20000 1400000:40000 1700000:20000
Hispeed_freq: 1190400
min_sample_time: 80000
sampling_down_factor: 0
target_loads: 85 300000:40 700000:45 900000:55 1200000:65 1500000:75
Dont forget to hit apply at boot on the cpu section of kernel adiutor, otherwise once you reboot it will revert back all the changes you made
Changed first post based on experimentation and better results with the above settings

SM_T230NU: GPU Frequency is only listed as 0MHz?

Been tweaking the tablet for a bit to make it not run so badly, and I noticed something odd: the GPU is listed as running at 0MHz on any kernel-tweaking apps I try (Kernel Aduitor, Device Control, etc.)
I flashed stock kernel as well as the 3 custom kernel available but the issue remains. I even went into the GPU frequency files located in /sys/devices/platform/galcore/gpu/gpu0/gpufreq for 3d and /sys/devices/platform/galcore/gpu/gpu1/gpufreq for 2d, with files such as "gpuinfo_min_freq" and "scaling_max_freq" following the available listed frequencies in the file named "scaling_available_frequencies" for both GPU folder, but none of the changes I make affect anything.
The files listed always say that the that the lowest GPU frequency is 156000 (in KHz, or 156MHz), but changing the values and saving the files doesn't affect anything, even with Root & Mount Writable privileges.
