Hello all!
Since bios 307 or 308 (cant remember at all) i lost the possibility to undervolt my CPU (i7-9750h) either with ThrottleStop or Intel XTU. I want a modded bios that let me undervolt again my cpu to reduce temps. I upload my dump bios (I think is from Windows Update firmware) and the last official bios from asus in the zip file just in case it was necessary. I can update my bios to the 311 official, i saw here that can be problems updating unlocked bios from the windows downloaded bios.

Any way, is there any more mods to apply on this bios? I will be so happy just with the undervolt option unlock, but want to know if there is other options.
I have upgrade my bios to the 311 asus original, seems to be same as before.

Thanks in advance!

@Xphectro

Make a bios dump with this tool then attach the file. (Run dump.bat as administrator.)

Hello guys,

I have a Zephyrus GX701GWR (i7-9750h) and I have been dealing with high temps since I updated the BIOS (at some point, between BIOS v307 or 308 they removed the undervolt option due to a vulnerability on this CPU).

I have BIOS v311 installed, which is the last one that ASUS provided. I have been trying to get an older version with undervolt unlocked but its almost impossible. They retired them from the support page and I have not had luck on forums as well.

The CPU is reaching 96º degrees every time I start a game or a bunch of heavy apps, causing thermal throttling.

I was wondering if there is a possibility to custom this v311 BIOS in order to get the undervolt option back.

Thanks in advance.
