NVflash "EEPROM unkown" on 1050ti laptop

[sebaskitty]

hello good day.

i've been trying to backup the 1050ti vbios of my laptop's gpu.

so i can take a more in-depth look into some of the limits and maybe raise it a small bit.

the device does not overheat so i've been trying to overclock it a bit further,

but everytime i try to use nvflash (version 5.660.0)
i get the following message


"
C:\Users\sebas\Desktop\1>nvflash64.exe -b 1050.rom
NVIDIA Firmware Update Utility (Version 5.660.0)
Copyright (C) 1993-2020, NVIDIA Corporation. All rights reserved.


Adapter: GeForce GTX 1050 Ti (10DE,1C8C,17AA,39D0) H:--:NRM S:00,B:01,D:00,F:00


EEPROM ID (00,0000) : Unknown

Adapter not accessible or supported EEPROM not found, skipping"


is there anything that could be done?

or are the vbios of laptop systems integrated into the laptop's own bios?

Yes, that's the case with most low end to midrange laptops.
Sometimes you can still dump the VBIOS, but you cannot flash it back with NVFlash.

Does GPU-Z -> advanced -> BIOS work properly at least?

thats the first thing i've tried.

it says something along the lines of "bios reading not supported on this device"

i opened the laptop.

and i found 2 winbond chips. which are usually bios chips iirc..

If you run nvflash w/o parameters and hit enter button a dozen times, there is a list of supported EEPROMs

alright.. i wil try to get a flash programmer so i can read the bios chips and dig some deeper
