All is in the title, I advice people with the same config as me NOT to update bios to the last A23 version. I've got a MSI X870E carbon wifi with Ryzen 7 9800 X3D and for RAM: Corsair Vengeance Black - 2 x 16 Go (32 Go) - DDR5 6000 MHz - CL30 - Ryzen Edition.
Using UEFI menu or MFlash with flash button and USB key for updating to Bios 7E49v1A23 resulted in a non bootable system, the MB restarting over and over before the POST message. Clear CMOS button didn't help. Fortunately I could get my system back by flashing boas to Bios A21.

Hope this info can prevent problems and maybe help the MSI team to fix this

I had the same issue, reported over on gaming motherboards forum. Apparently MSI have reprod the issue (not everyone sees it) and awaiting a fix.
I was ok after flashing back to A21 though my Seasonic PSU went mental for a while and ran fan at 100% until I did a hard shutdown and restart.

There is no way MSI actually removed the (Beta Version) text from all their 870/850 BIOS versions from the site, released an untested BIOS version to the public that is now bricking the boards and then closed shop for Chinese New Year.

BE CAREFUL WITH 9800X3D AND AGESA 1.2.0.3 BIOS VERSIONS
LOTS OF REPORTS COMING FROM DIFFERENT MANUFACTURERS
IT'S DANGEROUS, STAY WITH 1.2.0.2

Also, to the moderators, if you time do some research and think if it's advisable to have a sticky post warning about the risk of this specific update for 9800X3D owners

EDIT: here's few links

Einige 9800X3D funktionieren nicht mit neueren AGESA Microcode

Hallo Community, es gibt immer mehr 9800X3D, die nach einem BIOS Update nicht mehr starten, dann bleibt nur noch ein Recovery auf das erste BIOS. Auch wenn man ganz neue Boards erhält, wo schon ein neuerer AGESA-Code vorinstalliert ist, passiert genau das gleiche und die CPU-LED bleibt ROT...

Strix x870E-E error code 00 after bios update

So last night I decided to update to 1001 bios version. Everything went great updated completed, restarts does some other update for couple seconds then blank screen and my fans continue to ramp up and down with a Q-code of 00. I let it sit there for couple hours and nothing. Since then I have...

@Alan J T Do you have the ability to contact SOS support? I understand that it is the lunar new year. It seems that 1.2.0.3a patch a really spoils processors. This applies to all manufacturers. Yesterday my friend encountered code 00 and only the first versions of BIOS 1.2.0.2 work for him. I had cyclic reboots and triple initialization of BIOS without code 00. This is very important and should be removed from the site. I hope that this is just a software malfunction and patches should be released urgently

Honestly, the X3D chips are most of the complaints with the Motherboards almost all that have problems have the X3D chips not all but Most

There is a very simple and non-technical reason for that: Look at the X3D sales numbers.
Despite launching two months after the Ryzen 9000 series, this CPU equipped with 3D V-Cache has already surpassed the combined sales of all Ryzen 9000 CPUs.

The X3D CPUs are selling like hot cakes and those who buy them are enthusiasts who will make themselves heard if things don't work the way they should.
So of course most of the complaints will be related to X3D CPUs.

I can confirm this also affects the 9900X. I fought for an hour and a half to get rolled back to A21. It is disappointing that they still have that A23 Bios posted for download.

Back USB Blue Port: EXTERNAL HDD WD Purple 8TB 7200/256M (WD82PURZ) with separate power connection.
Back USB Blue Port: EXTERNAL DAC/AMP FiiO K11 with separate power connection.

Issue: When a USB external hard drive or USB DAC/AMP is connected to the motherboard back panel, performing a CMOS clear causes booting issues.

* On A1G(unofficial) BIOS, No boot issue.
* On A2 BIOS, the system freezes at "Q-code: 00".
* On A24 BIOS, the system enters an infinite boot loop.

However, After a CMOS clear, if the external hard drive or DAC is unplugged before booting, the issue does not occur.
Once the system successfully boots for the first time, the issue no longer occurs, regardless of USB connections.

Boot loop with bios 7E51v1A24 with MAG x870 Tomahawk motherboard https://forum-en.msi.com/index.php?...870-tomahawk-motherboard.408662/#post-2315939



So, I been posting all my problems on this subreddit and slowly been able to fix one by one.

But now with the latest firmware there seems to be a boot loop that happens and it is because a certain USB device is plugged into the USB 5G port (at least in my experience this is what it was, and I think the middle one was the cause, if the location matters)

I believe the exact kind of wire it was a USB-A to USB-B 2.0 Cable - it looks like this: https://www.amazon.com/gp/product/B00BCWALHM?smid=ATVPDKIKX0DER&th=1 (not the exact brand I am using though)

Once I unplugged this completely it worked.

Never once had an issue with this bios till I placed in sleep mode once, then this boot loop started. Not sure if related, but that was the only thing I did different since I had this bios. I just went to sleep with my computer like two days ago or something and now this issue is happened.

BIOS A20 and earlier: The BIOS does not recognize USB hubs or any devices plugged into the hubs, but plain USB mouse and keyboard work fine. After Windows boots, all USB hubs are recognized and work.
BIOS A24: The system goes into a boot loop until the hubs are unplugged (the plain USB mouse and keyboard work). After Windows boots, all USB hubs and devices work fine.
My system build is in my sig.
