It seems that MSI removed last bios update for motherboards with b450 chipsets and i see on some b450 mobos they added it back with same changelog but with a different version id as BETA (as far as i remember last 1.2.0.7 bios was released as stable), seem that it was probably bugged. ex. is missing from B450 tomahawk max , maybe for other chipsets too but this is the only one ive checked.

Removed Bios:
B450 TOMAHAWK MAX (MS-7C02) V3.E BIOS Release
2. This BIOS fixes the following problem of the previous version:
- Update to AGESA ComboAm4v2PI 1.2.0.7.
- Change the default setting of Secure Boot.
Release Date: i think it was 2022-06 or 05

New bios they just added (that replaced the other bios)
B450 TOMAHAWK MAX (MS-7C02) V3.F1 BIOS Release - (Beta version)
2. This BIOS fixes the following problem of the previous version:
- Update to AGESA ComboAm4v2PI 1.2.0.7.
- Change the default setting of Secure Boot.
Release Date: 2022-07-05

I am guessing, as i said in the other post, that the first bios had some bugs so they just replaced it , im still using the older one and i dont have any problems so far but maybe this will help some other people with b450 / x470 boards that have instability issues.
 
Agesa 1.2.0.7 solves some crucial bugs, yes. TPM module stutter which is used with Windows 11.

Yes , but the idea for my post was that the first bios with ComboAm4v2PI 1.2.0.7 ( V3.E) that was released a month ago or so (as stable) was bugged and they removed it then they released new one ( V3.F1) as BETA a few days ago (basically same bios with some fixes i guess?) , i think some people had problems with RAM on b450 / x470 because they didnt do it only for TOMAHAWK MAX , they did it for all motherboards with those chipsets (in stealth :D).

1.2.0.7 added new CPU's as well, but broke PBO for a lot of users as well.

I assume another update is coming, sooner or later.
 
So I won't have to D/L a specific bios when I get a 5700X/5800X?
 
Erm, 1 sec...

Bios 2.GO but I'm on Mortar MAX.
 
I dont like the fact he MSI changed the default bootup option to UEFI and did not leave it on CSM.

How do they expect people with older GPUs to go into the BIOS and change that!

Anyway rant over. Im running 1.2.0.7 on a B450M Mortar Max and its been problem free and performance seems better than 1.2.0.6C

Do you use the updated bios from few days ago or the first release (1.2.0.7)? You can get into bios even you have an older GPU as far as i know.
 
1.2.0.7 V2
 
CSM / UEFI doesn’t prevent pc from starting into bios, just windows can be faulty.

ofc all new Ryzen run with this bios.

I am using the first release. On the day it was released.

I have tested it and when you do a reset BIOS with 1.2.0.7 it defaults to UEFI and the BIOS wont load but windows will once its starts up.
So you cant make any changes in the BIOS if you running a non UEFI BIOS GPU when its on UEFI mode. Older versions defaulted to CSM when you
reseted the BIOS.

Just something to be on the lookout for if you are running an older GPU.

Maybe this has been fixed in the new version? Will check it out now.

Afaik windows has a function to reset into bios. Use that. Fixed

I thought, being a noob, that you had to download a specific bios for a specific chip. Of course.

Well, one bios always supports multiple chips. Usually a lot of different CPUs. You can see the table if you go into the support page of your mainboard.

I own the board and have tested this out.

I used my RX 480 which has a UEFI BIOS and switch it to CSM so that my 5570 can work.

It worked great until I had to reset the BIOS which defaulted back to UEFI.

In this mode there is no display when you press DEL and enter the BIOS.

The only solution was to put my rx480 back in and change it back to CSM.

So you cant go into the BIOS but once windows loads GPU driver the display shows.

WIth BIOS version 1.2.0.3C and 1.2.0.6C when you do a reset BIOS it defaults to CSM.

What i was getting at is msi really doesn't care. But from what you just said it now defaults to CSM, which is Good.

The AsRock B550 Steel Legend I believe defaults to CSM out of the bix
 
I have b450m pro-vdh plus and lastest bios is missing in website. fTPM not working with 7A38v9D (Agesa 1.2.0.7 update) version. This version have bugs. Maybe that's why MSI canceled it.
 
May bios 1.2.0.7 Agesa for MSI B450m Pro A Max has also been pulled, I suspect there was a slight problem with some of the early 1.2.0.7 Bios' and MSI have pulled them and will release an update soon, I'm sure they have done something similar not so long ago, I have the removed BIOS update and have no issues that I can perceive...
 
B450 Tomahawk Max II here. Downloaded & flashed the 1.2.0.7 AGESA BIOS before it was taken down. I prefer it over previous BIOSes, it doesn't delete all BIOS profiles when I clear CMOS.

However it's interesting a replacement BIOS for this board has not been published yet by MSI, only 1.2.0.6c AGESA is currently live.

Anecdotally, I did not find any critical bugs during a 1600AF OC session. As others have said I'd expect replacement BIOSes soon.

Situation is at least a bit better than ASRock, which for example hasn't published anything past 1.2.0.6b for the B450 Pro4 r2.0 (March 2022 date).
 
TBF, as good as this B450 has served me for 2-3 years I will likely go B550 very soon for PCI-E 4 and hopes of higher RAM speeds, currently I seem to be limited to 3800, though as the Ryzen 5500 is practically the same silicon as the 5600g without IGP, I was hoping for 4000+ still can't complain at the amount of support they have given for 3/4 years
