Possible downgrade in Bios version?

[piQmi]

Hello!

Here's the thing, I have a ROG STRIX B650-A GAMING WIFI motherboard and I updated the Bios to the latest version

Version 3042
Code:
"1.Updated to AMD AGESA PI 1.2.0.2.
2. Phase in AMD cTDP option to 105W for particular processors.
Before running the USB BIOS Flashback Tool, rename the BIOS file (SB650A.CAP) using BIOSRenamer.")

And now when I turn on the PC, sometimes (not always) I receive an error message, which can be seen in the image below:

Until before this update I never received this message, to resolve it, I just go to Bios, exit and then enter Windows.

Today I was playing Valorant and streaming at the same time and the PC crashes and restarts, no Blue Screen was displayed, but a Minidump was created which I also leave here so you can analyze it better. Minidump

Note - I only have EXPO turned on in the Bios and in the Curve Optimizer set to ALL Cores > Negative > -25 and this has never caused a problem.
Note 2 - I have Windows 11 24H2


Will it be possible to downgrade the Bios to the version I had before?

Looks like it has the flashback feature.

You should take the curve off if it has not been tested. I think that is why it crashed. I am on old Zen 3.. but the same thing happens.

Its trying to boost too hard with not enough power behind it.

But since I have the processor I have never had this problem.
It was exactly after updating the Bios, should this be like this?

I just go to Bios, exit and then enter Windows.

Why did you "update" (update is a more applicable word than "upgrade") the BIOS? I update with new builds, but once stable, I don't again unless the update addresses a problem I am having, or adds new features or support for new hardware I need. I never update the BIOS just because a new version is out there.

You could "rollback" (downgrade) to the previous stable version. Or, if you are just exiting the BIOS, you might try setting any timing or voltage changes to the default you made, then instead of simply exiting, select "Save and Exit". Then see if it boot properly.

Something in the new BIOS has changed and now your -25 offset is no longer stable. Maybe it never was and you just got lucky. So back it off to -20 and see if the instability goes away.

Yes it makes perfect sense.
Thanks

I understand! This is something that doesn't always happen, it's kind of random.
Thanks for the clarification.

That's exactly what I thought. Something changed with this latest update and now -25 is not so stable anymore.
Interestingly, in the Minidump that I left, it talks about something related to Valorant. (but I don't know how to parse Minidum)

But yesterday, I did a Stream, playing Resident Evil 4 Remake, with the settings at maximum and everything went so well.
