With >>Forum UEFI Shell Flash Tool<< you can copy the hash of the BIOS file quickly for checking,
by loading the BIOS and click over BIOS-SHA256 on the bottom:
2.jpg
then in this topic do press CTRL+F to paste it to check if will match it.

Aside from this you can check AGESA version,
and / or let the tool prepare the USB key for flashing either by the tool by booting from USB key or by M-Flash.
While doing USB key preparation it will ensure the BIOS integrity on the USB key both checksum and SHA256.

Don't tell me "no problems here" or "it's working great"—I've used BIOS versions a95, a99, and 1AA1, and I've consistently run into the 0D error.
BIOS versions a95, a99, and 1AA1 still trigger the 0D error, though it happens less frequently than before. Dealing with the 0D error today has been a real headache. I’m hoping the issue won't appear in AGESA version 1.3.0.1b.

maybe memory compatibility problem?

It's due to RAM compatibility issues. I had that error with Corsair 6000 MHz RAM... luckily I had 7200 MHz RAM, and I haven't had any more "0D" errors since. There should be better RAM compatibility.

It's also an issue with running multiple conflicting hardware monitors at the same time (or at least it was). When AM5 first released, you couldn't run iCue and HWinfo at the same time or you would get 0d upon trying to restart. I think HWinfo fixed that in one of the latest releases though.

Yes, perfectly normal, as you can’t run 4x Gen4x4 plus VGAx16 in this configuration. You can only run VGA x8 since one of the M.2 ports shares lanes with VGA namely M2_2. You can run 3x NVMe while keeping VGA x 16, but you still have to pay close attention to which NVMe ports you populate to avoid lane sharing.
No BIOS update will ever change that as it is hardware limitation of the chipset and board.
Check this link to see LANE configurations for Carbon Wifi to avoid lane sharing:

Thank you so if I understand corectly if I buy lets say 5090 will work on gen 5 but only x8 more, so genaration will change because of the gpu ?

I wonder which BIOS is newer, 1AA0 or 1AA1?

Svet, maybe there's an even newer beta?
Click to expand...
I would think 1AA1 is newer and that they just took a really long time to certify and release A0.

Also, why is MSI always so freaking behind on AGESA versions? Seems every other MB maker already had 1.3.0.1 out a month and half ago or more and ASUS already has 1.3.0.1b. If we're lucky we'll see that one in like 6 months.

Unfortunately, yes in a 4x NVMe configuration, any 5th gen VGA will run at 5x8. To avoid this and maintain x16, you’ll need to sacrifice one NVMe drive and keep the M2_2 port empty, as well as the PCIe-2 slot empty. IIf you place any add-on card in that slot, no matter the generation of the device, it will reduce the VGA to x8 again.

It's being abandoned/de-prioritized now that the Carbon Max and the rest of the Max line is out seems like.
Click to expand...
Not entirely, but we will see less frequent updates as it’s lower in the stack priority. This has happened with every board I’ve owned over the past 20+ years with, mostly ACE and then ACE MAX. I noticed that once the MAX was released, the vanilla board received updates less often, and the between BIOS releases became much longer.

Ps. The system shows that A0 is newer than A1?
Click to expand...
MSI used to version their BIOSes with the 0 being the current release, and all other numbers at the end were beta or major bugfix versions. Maybe they're moving back to that pattern?

AA0 - Current release
AA1, AA2, AA3 - Betas/major hotfixes
AB1, AB2 - Next major betas
AB0 - Next major release...

There's something wrong with the AA0 BIOS.
1. The AA0 BIOS can display error code 23 for only about a minute. When changing the settings "Read Preamble P0 4tCK->Auto and 6 options setting Prefetcher Enable ->Auto" after saving it, it reboots and detects code 15, then code 23 for 1 minute. I thought it was a hang error for 1 minute with code 23, after which it can boot normally.
2. After entering the BIOS, it sometimes won't exit the BIOS; you have to save the configuration before exiting the BIOS menu.
