[OnePlus 9] xlinux_:
This is a short how to guide on how to successfully over clock GPU past its original clock speeds without changing any other settings

-------------------------------------------------------

Warning USE AT YOUR OWN RISK ! This will void your warranty. Do not use this method if you don't understand the risks involved of overclocking. Nobody besides you is responsible for your device this includes bricking the device, dead SD cards, loss of data that is all on you!!

--------------------------------------------------

make sure to make a backup of your Vendor_boot.img store it on a separate drive like a pc or laptop, so you have a back up that way you don't have to worry if you mess up!!

IF you fail to boot for whatever reason :

------------------------------------------------------

reboot to fastboot mode

TO FLASH BACKUP- in cmd type:

fastboot flash vendor_boot vendor_boot.img

What you need -

You must have either magisk or kernelsu Installed and root working.

The guide -

First off don't do this if you're using your phone as a daily driver it can impact the devices lifespan so please be careful with any type of overclocking. I have made sure there are plenty of warnings before proceeding please consider that this is only for testing purposes. And may not align with your daily usage. Especially consider what mods you download online always be safe!!

-----------------------------------------------------------------

Within the app you'll be approached by selecting the model of your Snapdragon chipset module each device may have a different chip set but generally its under the first selection (0) so for example

: snapdragon 888 (0) \>

Tip : Do not go over 855mhz you have been Warned!!

Next--

----------------------

Edit the first three numbers of the frequency you're currently modifying

" 840"

So for example :

"840000000" (6 zeros at the end of 840)

And put the value you desire don't delete the zeros at the end of the three digits.

I tend to stick around "845"

for example :

"845000000"

Probably don't mess with any of the other settings if you don't know what they do.

--------------------__________________________---------------------

Be sure to save the table backup your original vendor_boot.IMG as mentioned earlier this should have already been done.

Flash the table within the app.

reboot and success!

Hint: you can also add different frequencies incrementally to find what your devices Max is. I find my device only can handle "845" for example.

This is nothing special just thought I'd share in case others didn't realise you could do this :).

I know a lot of enthusiasts would enjoy this method please full credits to libxzr for creating this app

TIP: you can also undervolt the gpu which will improve battery and not impact performance to much., especially if you're a enthusiast like myself its great to see how far you can go before losing any performance as well as increase those battery percentages, possibly keep the device cooler

And last longer. I tend to do this more often, over clocking does improve gaming performance though..

I'm not a developer this is just a guide!.
