I did not test this one I see what msi is doing now every time there is a new amd code they screw up the bios .

 

[jankmail15af02e1]

Bios A75 error , dont use it
1. cannot upgrade dbx on Secure boot.
2. after save configuration bios, reboot detect code 15 after that become code 00 and then frozen everything same like old bios A23.
Revert back to A65 everything back normal. Using A64 sometime error using memory KLEVV CRAS V RGB 2x32GB 4 slot.

The BIOS is removed now lol. Also since many BIOSes, the EXPO indicator seems to be bugged. Is this just a visual bug or something deeper is bugged?

See attachment. EXPO is not lighting up. When EXPO is selected it should get highlighted with pink/purple right?

My memory is A-XMP compatible, and it does light up when selected. It correctly reads the two available profiles and works without issues on my Corsair Titanium 7200. However, I prefer to run this kit at 6400 + 2200 + UCLK=MCLK, CL32, and all previous BIOS versions had no issues, until this one. I was able to select a close profile, "TRY ME," in all previous BIOS and it worked fine. However, with this BIOS, the system won't boot, and I get the 3-beep error tone, indicating memory not detected. Even if I set 6000+2000 or any other profile in between, nothing works except the DEFAULT and A-XMP profiles.
So, I manually entered all my timings, and I got it to work 6400+2200+UCLK=MCLK as desired. Another thing is that it auto-enabled CPU GAME BOOST, and I don't know why, even after CMOS clear.
I also noticed the BIOS feels very sluggish with the mouse, which I have never experienced before. However, once I set up everything, the system works pretty well with no issues whatsoever. As it is stable and performs well, I won't be flashing back to A64, which was the best BIOS in my experience and the BIOS I updated from.

Just to clarify - This bug happens when you re-enter BIOS after saving EXPO enabled setting. It doesn't light up.

I installed A75 and had no issues. Windows 11, version 25H2, 2025-11 Preview Update (KB5070311) (26200.7309).

So why was it pulled from download page? What kind of issues? Is it harmful to hardware? MSI should say something.

You can't expect MSI to ever say that every new AMD implementation of Agesa is crap.
It seems they quietly pulled out that bios 1.2.8.0 for all motherboards after what was posted everywhere, everywhere, starting with GURU & TPU, it should be something wrong with that UEFI version

AMD AGESA v1.2.8.0 May Prevent BIOS Entry and Crash Systems

AMD is gradually releasing the AGESA PI 1.2.8.0 BIOS update, which primarily aims to enhance memory compatibility. However, users who have installed this BIOS version are reportedly facing issues. A member of the Chiphell forum installed the latest AGESA PI 1.2.8.0, hoping for improved system...

As a matter of fact I do expect them to say something when they pull a bad BIOS version that people have already downloaded. What sort of logic is yours? [***CENSORED***] them?

Yeah, something like "Be aware if you flash it do it on your own risk, might be lack of improvement & stability" would be nice to hear from MSI being ironically.
Same withdraw was happened already with 1.2.0.3g version, is not the first time for them

All I know is that BIOS A75 is wonky. After all the strange issues I experienced and a deeper investigation, including the pages mentioned here, I decided it's safer to revert to A64. Good thing in all this fckry, I reverted without issues.

 

[sgmwright]

im on 75 and its actually more stable for me than 70, every bios before even 64 i would get random crashes

Good for you, but with these strange issues reported and my own experience with my hardware, the BIOS isn’t setting things up as it should, especially on the memory side. So just to be safe, I reverted back to A64.
As I wrote before, after setting almost everything manually and getting the settings that usually always work, the system performed very well. In fact, I got slightly higher single-core CPU results but lower multi-core results, while on 64 it’s the opposite, though the margin is small and doesn’t affect anything either way.

Hey chill out guys, all fine and don't worries if it's already working for you, be patience, it seems to be a memory compatibility issues for X870E Carbon & B850M Mortar only with some of chinese manufacters like Kingbank, KLEVV, Gloway or OLOY PCB modules on latest Bios 1.2.8.0 so far, pretty sure they will fix it & putting back on Official support site for all mobos soon
Brand New DDR BUS config section with custom Group A & B values are in developing from Tech engineers related departament, we shall see it implemented on all MSI boards, hope to see it working great 8400GearOFF with 6000C26 A-Die sticks in same compatibility GroupB like for AYW

not entirely true I had major issues with my Corsair Titanium 7200 48GB DDR5 and this is the very first BIOS I ever encounter such issues with that kit

Not fully understand what issues you have had with Corsair 48gb on Agesa 1.2.8.0 pretty sure not the same, those mentioned memory kits simply doesn't boot, no Bios screen shown up even after CMOS, did you have it?
Those are major issues encountered i was speaking about, some enthusiast finally ended on booting with only one memory stick after CMOS just to reverted back previous stable UEFI.
Keep in mind 2x24gb memory kits don't need custom GroupB inserted in DDR BUS config to run 8000+ GearOFF frequencies anw, so upgrading to 1.2.8.0 seems pointless to me at this point, unless you aren't stable enough.
Once your system is stable, there is no need to update the BIOS for more headaches ended with no benefits. This is a phrase I often tell my clients, some time they listen, most time they don't and they flash UEFI by themself in vain, just to reverted back

It's not as drastic for me, but I mentioned it in a few posts above if you're interested. The BIOS is definitely wonky. In the meantime, I switched to Kingston Fury Renegade LE 8000 CL36 48GB but reverted back to A64, which works amazingly.

 

[rand_1152702d9]

Possibly an issue for someone, saw it mentioned that this newer AGESA correctly applies trfc2 & trfcsb timings. So if you have low timings there, or autoapplied from whatever profile, it's probably gonna mess something up.

Which BIOS version is currently the best? A64?
I need to update my BIOS because of some GPU issues and I hope this will fix them. My current BIOS is still from November 2024.

btw, is there any BIOS version that has fixed the PCIe speed issue, or is this still common in the current BIOS versions?

I'm on A64 and so far so good. I would recommend you to update to this one for now

A64 here works best on my system and settings no issues with my Kingston Fury Renegade LE CL36 8000 @ 8000
