ASUS x670e Extreme bios update was interrupted but still updated?!

Level 7

Hello all,

Hope you are doing well.

Today I have updated my motherboard from 1303 to 1709 but the weird thing is after I started the update, got the "bios have been updated successfully system will reset" message from EZflash window, system restarted then a black screen with "don't turn off the system" message appeared, then system restarted again and I got stuck in code 77 and no screen for 20 min. I forced a shutdown tried to start the pc but the same error appeared then I unplugged everything except the mouse and keyboard  and started the pc then an "ami" labeled message appeared saying there was a problem with POST or something please press F1 to run setup I got into bios with the update 1709 and system and OS seems fine. what happened and was the bios update successful? I remember the first time I updated to 1303 it restarted a lot so what happened now? I still didn't test the system or enabled EXPO again. Should I be concerned? Can I check if the bios image not corrupted?

Note: I have amd ryzen 9 7950X and a msi 4090 suprim air cooled gpu

The BIOS has a checksum for verification of completeness and validity. You will get a serious warning if it is invalid at start up.
If you further have enabled UEFI BIOS, then it will check a signature ensuring that no one (hackers, vira etc) have tampered with your firmware, and if this test has been passed, it is close to impossible that your BIOS is invalid in any way.

Windows 11 requires UEFI to start. To check for UEFI in Windows 10 right click the Windows symbol and start disk management. Your Windows partition should be marked "EFI"

To check the BIOS version right click the Windows symbol and start powershell and type or paste:

wmic bios get smbiosbiosversion

Then hit enter and Windows will print the bios version.

When you update the firmware of the motherboard, then it is common that BIOS settings are resat to factory default at least at some level.
This could explain the unsuccessful restart.
Usually, errors are fixed automatically when you restart your system after an unsuccessful start up, or when you enter BIOS setup, but better check any custom overclocking, memory timing etc.

Hello, @Zero0Z0 

The latest BIOS 1807 for the ROG CROSSHAIR X670E EXTREME was released on December 15, 2023.
May I ask about the specific BIOS functionality requirements or hardware changes that necessitate updating to version 1709?
If you've successfully completed the BIOS update, cleared CMOS, and entered the system without encountering any issues currently, we recommend monitoring the system during usage to observe any potential changes or abnormalities.

Thank you.

Due to the ongoing regional holidays, my responses may be slightly delayed.
Thank you in advance for your patience.‌‌‌‌ 🙂
