I have an ASUS TUF 3080 10GB, the sub ID is [1043 87C4]. I am having trouble with Enabling Re-Sizeable BAR. None of the BIOS from ASUS site allows me to update it. My current bios version is 94.02.42.40.63 and according to the BIOS read out it's 94.02.42.00.AS31 with a BIOS build date of 2020-11-26 00:00:00. I have been unpacking the BIOS upgrade utility and have not see any that seems to go with this particular sub version of the card.

Any suggestions on finding the right BIOS so I can get the Re-Sizeable BAR working?

Gigabyte X570-i AUORUS ITX, BIOS F34. I just recently flashed it and haven't even touched anything besides 4G and CSM disabled and setting Re-Sizeable BAR to AUTO (only AUTO or Disable)

Just a quick update. I was able to resolve my issue. It turns out it WAS because of the old vBIOS and something is wrong with Gigabyte BIOS as well.

I moved my ASUS TUF 3080 prior to the vBIOS upgrade to a MSI B450 Gaming AC motherboard for a test and it was able to turn on Resizable BAR. However it required additional "work" to get it going on the Gigabyte X570 I Aorus mobo. I also needed to upgrade the vBIOS.

I was able to resolve my issue by the "unconventional" means.

  1. Figure out which BIOS I needed that is later than 12/11/2020. My card came with BIOS 94.02.42.40.63. Device ID 10DE 2206 - 1043 87C4. I was able to find 94.02.42.40.64 with the same Device ID 10DE 2206 - 1043 87C4 on TechPowerUp
  2. download the bios from Techpowerup.
  3. manually using NVFlash and flash the bios.

Gigabyte quality is a oxymoron
