RTX 4080 Laptop VBIOS values and editing

[SuperMG3]

Hello again.

 

I have an RTX 4080 MXM card. My laptop is a Clevo P570WM that can handle max to 115W of heat.

 

The MXM card can use up to 150W. On GPU-Z it says max 150W too. The max temperature before thermal throttling is 83C which is annoying.

 

I just wanted to know where I can find the value (inside the file) for the TARGET LIMIT of the TDP and the MAX THERMAL LIMIT in celsius.

 

I want to set the max target limit to 115W and the max thermal limit to 87C.

 

I can't flash any random 4080 laptop VBIOS because my card has MICRON VRAM chips. It means, every VBIOS available on the net only use Hynix/Samsung combo, no Micron available.

 

I know unsigned vBIOS without the correct checksum won't work. I do own a CH314A for flashing tho.

 

I just want to know if someone knows how to VBIOS mod the TDP limits and thermal limits. I know someone edited the vBIOS of an RTX 3060 Ti Ampère but he didn't explain how sadly...

 

So if any of you knows, please write it down.

 

Thanks.

I'm a little bit late.

 

Actually, the vBIOS is uploaded on techpowerup. It's the "X-Vsion 4080 12GB".
