Undervolting Help [BIOS 309] [ASUS GU502GU]

Abn0n
Level 8
I have a Asus Zephyrus M GU502GU. My CPU temps in armoury crate have been hitting 95 the moment it goes on turbo (high performance mode) and my laptop has been overheating a lot. I have cleaned the fans and stuff and the problem still persists. And now I realized along with GPU overclock that is missing from my armoury crate (I have posted a seperate thread for help on that issue as well) I am unable to undervolt using XTU. I really would like to undervolt this system as I have heard it does create a difference in CPU temps. I think it is locked in the BIOS 309. Is there a way to go back to a previous BIOS to enable it? I have downloaded the bioz zip file from the support page but I am not sure how to go about it, and if its safe to. Really appreciate any help regarding this!

Hello Abn0n,
You may downgrade BIOS by EZ flash, the same way you upgrade BIOS.
Thank you.

Hello

Can we do this also for Zephyrus M GU502LV with i7-10750H CPU with BIOS version 309?

BIOS version 307 is unlocked? Can we flash it wit the EZ utility?

Thank you
