Motherboard BIOS update breaks Afterburner GPU overclock?

I tried running Timespy Extreme on my system today and noticed that my graphics score had gone down from ~10700 to ~9900.

I use MSI Afterburner to undervolt my 3090FE and when I checked the settings it showed that my GPU was running at stock and no profiles were defined.

I then checked the Profiles folder within the Afterburner install and noticed that there was a new ".cfg" file with a slightly different name which contained no profiles.

The name of the new "empty" config file was:

VEN_10DE&DEV_2204&SUBSYS_147D10DE&REV_A1&BUS_11&DEV_0&FN_0.cfg

and there was another older and larger config file called:

VEN_10DE&DEV_2204&SUBSYS_147D10DE&REV_A1&BUS_7&DEV_0&FN_0.cfg

When I opened the older config file in wordpad I could see my profiles.

I then tried renaming the older config file to the name of the new config file (by changing "BUS_7" to "BUS_11") and restarted Afterburner and all my profiles were back and so was my Timespy score.

The date on the older config file (before I renamed it) was from Thursday which just happened to be the day I updated the BIOS on my Aorus B550i Pro AX. It looks like when I updated the BIOS it changed the PCIE BUS identifier which is returned for my GPU and that stopped Afterburner from recognising it.

I don't remember ever having to do this before with my previous Intel setups. Is it normal for a motherboard BIOS update to change the PCIE BUS ID?

What does the BIOS release notes say - also was it one BIOS update version or did you need to update it through several ? eg F10 to F11 or were you on F10 and went to F15.

I went from BIOS F13 to F14.

There aren't any release notes in the BIOS download, only some bullet points in the description on the website:

  1. Checksum: 2CB5
  2. Update AGESA ComboV2 1.2.0.4 A
  3. Change default status of AMD PSP fTPM to Enabled for addressing basic Windows 11 requirements

I updated mine to 14c a while ago, i've had no issues, but 14c was the 14 BETA BIOS.

It should not change the PCIe ID. i don't see why the BIOS would do that.

Now on Windows 11, updated BIOS while on Windows 10.

If i update my BIOS soon i'll let you know how it goes, its just a time thing for me, i have everything set up just so so i would want to do it when i have time to set it up again and test it.
 
anything's possible with gigabyte bios's, i run a x570 auros pro with 4 sticks of 8gb 3200hz which requires a cmos reset and a stick of ram unplugging now after every update when 4 sticks or ram are plugged in. i then have to put the settings back in and replug the 4th stick back in...prior to f32 this was not required. might help if they had more programmers and testers in the board bios department...
 
Sorry to resurrect an old thread but I just updated my BIOS from F15 to F16a and it's changed the PCIE BUS identifier for my 3090 again.

Once again it meant that my Afterburner settings were missing until I renamed the config file to have the correct BUS ID in the name and restarted.

Definitely something to watch out for if you update your BIOS and think your GPU performance has dropped.
