Updating notebook VGA BIOS

[palimad]

Hi guys, I have this BIOS on my card:

Lenovo RTX 3080 Mobile VBIOS

16 GB GDDR6, 585 MHz GPU, 1750 MHz Memory

www.techpowerup.com

Problem is, that the TDP is quite limited and I am tempted to try BIOS with higher TDP. Mine has 80W and max is 100W, so I was wondering about flashing this one for start:

MSI RTX 3080 Ti VBIOS

16 GB GDDR6, 585 MHz GPU, 1750 MHz Memory

www.techpowerup.com

Do you think that it would be safe and I can use backup flash file if something goes wrong? I am expecting, that if new BIOS on nVidia card won't work, I could still use Intel card in Windows. Would it be worth it considering it would get me 5% more gain in limit TDP? If my thermals are fine, could I be perhaps watching also for BIOSes from here that are around 100W like this one: https://www.techpowerup.com/vgabios/251148/251148?

Let me know your thoughts, thanks

Probably you can only use BIOS'es from Lenovo, specific for your laptop since these days the GPU is mostly integrated in the mainboard and so is the GPU BIOS most likely integrated in the laptop main BIOS.

This guy did something similar in a previous version of X1 notebook: https://www.reddit.com/r/thinkpad/s/MHGdoK4wmM

Its simple my friend, if GPU-Z cant dump then the vbios is main bios integrated, dont mess with it, my advice only.
Thats why that X1 user could play with it, because its a descrete GPU
We dont know your Lenovo model as you didn't provide any.

I was able to dump BIOS, it's the one from this link as I mentioned in first post, I uploaded it:

Lenovo RTX 3080 Mobile VBIOS

16 GB GDDR6, 585 MHz GPU, 1750 MHz Memory

www.techpowerup.com

My notebook model is Lenovo X1 Extreme Gen 5 model 21DE001EUS

Well... still i can't advise such actions to unexperienced users and no advanced knowledge of recovery a death system board/gpu vbios.
Of course... if the user can afford the risks, that's their own choice.
And you can't never ask such things as "Is it safe...." a lot could go wrong and each case /system is different... but for 5% i wouldn't for sure against risks.
Good luck

Different GPUs here. Yours is a 3080, the MSI is a 3080Ti.

At the end I was able to experiment with multiple VGA BIOSes and all went kind of well. The only downside is, that it did not help to flash BIOS with higher TDP as games started to stutter. Seems like drivers or something throttle down the clock extensively if temperature exceeds 80-85 degrees celsius. This happened even if I tried BIOSes with 115W target TDP (there are ones also with 150W). I put high hopes into this BIOS: https://www.techpowerup.com/vgabios/251148/251148 as it had 90W target TDP, only 10Watts more than my original one, but this one was the only one I tried and did not work at all (I was able to revert though, if someone is going to try this, remember to keep hybrid graphics on in BIOS otherwise you can brick your device if discrete graphics won't start). I kept this BIOS flashed at the end, as it at has higher TDP limit at least: https://www.techpowerup.com/vgabios/251362/251362 (and same target TDP). To flash I had to used this nvflash https://github.com/notfromstatefarm/nvflashk as the original nvflash did not let me flash different IDs of device. Thanks for help.
