Hi shiyab,

Thank you again for your help and patience. I have a few updates and questions regarding the EC chip:

Boardview version doubt:
The boardview I have seems to be for NM-B891 REV 1.0, not REV 2.0. I noticed this because the BIOS chip in the boardview does not match the one on my board (I have a W25Q80DV, but the boardview shows a different model). Additionally, some components and their positions do not align with what I see on my REV 2.0 board. Therefore, the MEC1663-WC_WFBGA144 shown in the boardview might not be the correct EC chip for my version.

is this? thanks...

The first thanks very very mucht

I look i have this MXIC MX25L25673G i thinking is this
thanks i go make this dump...

i thinking if posible:
GPU/VRAM overheats excessively
EC (IT5570) detects critical temperature
EC marks thermal flag in its own memory
EC orders VBIOS to "protect" the GPU
VBIOS modifies its tables:
- Reduces voltages (to generate less heat)
- Changes thermal limits
- Disables "problematic" memory channels
- Marks "hardware damaged" flag
VBIOS saves these modifications to W25Q
Next boot: VBIOS with "protection" configuration

GPU doesn't start normally, appears damaged
this...

From my tests and MODS logs, it seems like this could be a VRAM issue, but I’m not entirely sure:

3 × 2 GB chips installed → one might be completely dead, or it could be that the Falcon is not starting this channel because it detects errors in the other two chips; the other two show partial errors
1 empty slot → MODS reports it as “not initializing,” which could be normal

Falcon seems fine, but could it be affecting the slot/chips?

Would anyone with experience confirm if replacing the failing chips would be the right step, or if something else might be happening?...

yes thanks i go make this backup this weekend and i put you here, thanks thanks very much

Additional question: The Code 43 persists even with clean EC. I think the thermal flag is in the VBIOS (W25Q16 near GPU). If anyone has a dump of that chip for FA707NUR with RTX 4050 (SUBSYS 38E8), please share. I need a clean VBIOS to compare and fix my bricked GPU. Thanks!...

Thanks i study after i respond but the first thanks very much for your answer...

Hi, thanks for your answer.

The BIOS and EC firmware I’m using are the official ASUS releases, available directly from ASUS support website for the TUF Gaming A17 FA707NUR (2023).

The EC firmware version (for the ITE IT5570VG-256/CX) is R3.00 or R3.01, depending on the BIOS version (300 or 303).
I extracted the .CAP files and separated DXE and EC-related modules using UEFITool and IFRExtractor, but the EC binary region isn’t explicitly separated inside ASUS’s update packages — it’s flashed automatically by their EZFlash utility during the BIOS update....
