If u flash stock frimware with Odin without turning on bootloader ( OEM ) then your WARRANTY is STILL THERE  and will not trip Knox.
(Using download mode and official firmware from Samsung)

but 

if u turn on oem(or bootloader) or 
flash other funny things besides the stock firmware found on samsungs website (you will need to bear the slow speeds)
then u will void your warranty....

 so make sure to get your firmware with your correct region from  and

 if u know how to flash the stock rom do it or else follow tutorials on Youtube 


KNOX ?

imagine that Knox is like a "little copper wire" inside your phone which is controled by software. Once you install a custom rom or root, the Knox is tripped - in another words that little wire is cut in half. By doing that you ofcourse void your warranty and you can never undo it. I hope that clarifies it a bit.
 If you want, you can google "e-fuse" and find out more info about nature of knox...



- Wishing you Luck.

Don't even think about it. Exynos will not handle overclocking. Never try overclocking on midrangers because midrange processors always run on high power (because overall CPU output is low) So, no. Bad idea. If your phone is horribly slow, then try it.

nothing much to do bro...
i too face this issue on my S9...

nowdays the SOC's are heavily binned for optimal settings from the factory.

you could play the game in cooler environment to reduce throttling for some time..

you can check how your cpu is throttled by CPU Throttling Test in playstore


https://play.google.com/store/apps/details?id=skynet.cputhrottlingtest


if it gets too hot i think 30 to 50 % will be throttled

usually game booster delays the throttling in games...

remember
it will void your warranty and
you can't use few payment apps like Gpay Etc
also some other apps like banking apps and Snapchat etc...

you can fix that by masking your root privileges to them but those are extra steps
