    Hi All,

    I have created an account here to see if I may be able to get some assistance. I'm not sure if this is the correct thread to post in (sorry if its not) but I need some help with my 2019 Gigabyte Aorus 15 W9 laptop.

    I recently purchsed this laptop used. It has an i7 8750h processor and RTX 2060 gpu. The 2060 seems to be the version with an 80W TDP limit. During overclocking the 2060 with Afterburner (voltage/frequency curve method) I was constantly power limit throttled while temps were ok. Not satisfied, I foolishly tried to flash the video bios on the 2060 to the bios from a 2060 on the Asus ROG Strix Laptop (which has a 90W TDP limit). I used a version of Nvflash (with board id mismatch disabled) to flash bios. The screen went black immediately after flash. Unfortunately this appears to have bricked the laptop. It powers on, HD lights flash but the screen remains blank. No external display output either.

    I did save a copy of the vbios using nvflash before flashing the new rom. I can retrieve this from HD. I could also download the vbios it seems from the Techpowerup VGA bios collection.

    I need some help to identify the video bios chip on the laptop and then hopefully program it using an EEPROM programmer.

    I have ordered a CH341a USB programmer (including 1.8v adapter and 8 SOIC test clip). I am just not sure which chip on the motherboard is the video bios chip. The motherboard is integrated (CPU and GPU on same board, not a removable MXM GPU).

    I am including a picture of the front side of the motherboard:

    Here is a picture of a Macronix chip (mxic 25u8033e m1I-12g) on the front of the board next to ram slots and gpu:

    Here is the rear of motherboard:

    This is a Winbond chip (25q128jvsq 1830) on the rear:

    There are two unkown chips on the rear. Unknown rear chip 1:

    Rear unkown chip 2:

    Questions:
    1) Please help me to work out which is the bios chip and vbios chip?

    2) Will flashing just the vbios fix the problem?

    3) What would be the best method to flash the vbios chip back to stock?

    Thanks for any help and advice,
    Rift.
