Hello, xyzbird.
May I ask if you are having trouble confirming which version is the latest when updating the BIOS of the ROG STRIX Z370-G GAMING (WI-FI AC)?
What adjustments have you made that need you to update the BIOS?
The latest BIOS version for this model is 3005, released on November 22, 2021.
In order to optimize the user experience, ASUS is still adjusting the format to display the update time corresponding to the software utilities uploaded onto the official website. It is expected that the display of the corresponding update time of the software utilities uploaded will be added in the next update of official website.
We apologize for any inconvenience this may cause.
Thank you.
