DO NOT FLASH the new AGESA 1.2.0.3e (beta) bios unless you're brave

[vivek.ra155702d8]

New AGESA 1.2.0.3e bios out for X870e Tomahawk too
Removed Link to Broken BIOS

IMPORTANT heads up - DO NOT FLASH this new bios if you overclock Memory, or care about getting back to an older bios easily:
-Had a stable daily 7800 36-45 profile at 1.43V that would not even run with this bios at 38-48 at way looser timings AND way higher voltages, all with GearDown disabled only at Nitro 1-3-1. No, I’m not interested in enabling GearDown mode, or relaxing Nitro to 2-3-1. It has never been required at 7800 on this board with my CPU sample and 3 different 2x24GB kits
-Boots way too quickly than before, I suspect it's not training long enough, and couldn't extend the training duration despite playing with Robust training, Increasing RX and TX taps, setting Nitro to 8x/8x, etc. Tried every trick in the book
-Max stable on my setup was only 7600 MHz, which is ridiculous
-CPU PBO with curve optimiser was fine in general, found no difference in CPU perf

Tried to flash back the older A52 bios I was on, and it wouldn't even enter M-Flash, kept hanging at 0d, which has never happened before. Did the same after clear CMOS followed by M-flash, clear CMOS followed by restore defaults-> save/exit-> followed by M-flash. Once entering M-flash failed, it wouldn't even post anymore, hanging at Ab, 0d, 97 etc randomly.

This is just nonsense, what kind of QA/testing do they even do before releasing a bios? Having been with MSI for a while, I know if there is an additional digit after the primary bios # (the 3 after the 7 in this case), it is a Beta bios and needs to be taken with a pinch of salt, but not having tested the ability to let users get back to an older bios is inexcusable.

Had to resort to Bios flashback to get back to A6 which seems the same as A52 and perfectly stable so far.

You can check it with this tool

ZenTimings v1.36 Beta Download

ZenTimings is an easy to use, lightweight, Windows application that can read and monitor the memory timings of AMD Ryzen processors on the AM4 platfo

www.techpowerup.com

Not sure if it's shown in BIOS Setup.



No, it will works fine in any cases.

After downgrading everytime I try to boot I get a message saying that my device will shutdown due to USB overvoltage detected, never seen this message before, and guess what, if I unplug all usb, including the wifi/bt antena and ethernet cable it still deploys the message and don’t let me boot.

This is a joke, never seen a BIOS break a system like this just because I decided to update and the diwngrade gets me this, neat. Now I have to wait for a RMA. Im legit losing it

First de power the system by unplugging the PSU, and hold down the power button on PC for 15 seconds. Plug in the PSU and boot should be good to go if not

Unplug your monitor USB as well keyboard and Mouse

I have latest bios flashed to my system,no problems this time,but MSI,wake THE [***CENSORED***] UP PLEASE,people paying lots of money to get those boards,it can't be that people flashing a bios and have to rma or have a ton of problems,this is UNACCEPTABLE for the price tag alone for the board,fix this crap PLEASE.

Do you have the same for B850M Mortar WiFi? 7E61.
And could you please provide some info about what was wrong - is it Agesa related or MSI issue? Afaiu memory training was not working as it is supposed to do?

 

[f.meyer156202e5]

I have a msi x870E gaming pro carbon,the latest bios updates worked fine here,but still i can't believe wat the hell is goin on with those bios updates,too many problems for people,i have a mobo that i payed over 500euro,then i may expect that it works,luckily i know this stuff,but how many people out there didn't have a clue about bios updates,they all must go back to the store where they buy it,thats not done,msi need todo better their best with their updates,or they update less and bring the bios when its safe,or they use us as beta tester,but then THISis the last time i buy msi,they just have todo their JOBS,nothing more or less.

Legit, I regret the day I thought i’ll be set goong with MSI, stutter issues with thow the designed the LAN ports in the 870E carbon Wifi and now this to put the cherry on the top. RMAing this absolute crap and never looking back to be a customer for them, goddam this awful

 

[f.meyer156202e5]

Big problem is that with other vendors also have their problems.
Its something that plague this gen and not alone motherboards,look @ nvidia with the 50 series.
To be honest i can't call this normal anymore,luckily my msi ventus 5090 works flawless to the day,but waited also a month or 2 to buy one.
But those company's have to think twice,it are strange and bad times,everywhere,inflation-war,so if they keep bring products like this on the market,big possibility many people keep their wallet closed,and then its a problem for THEM.
I think wat we ask is good support on products we buy and test more before bring it out,if people their stuff brake cause of bios updates,then something is serious wrong cause i never had it here,it are electronics,but it aint the procedure that a bios update kills a mobo.

As I said I unplugged all USB devices and it won’t boot, tried your suggestion and it sadly didn’t work with the PSU instructions.

Insanity that I have to go through this because of an update lol, guess ill RMA and just switch brands because god save me from having to go through a RMA thanks to a BIOS update, end user is the beta tester, good job MSI!

MSI's highest priority is to provide the newest AGESA version as soon as possible, regardless of the consequences.
So as long as people continue to pay lots of money, why should MSI do things differently?

I ask to not be a betatester when I paid 550€ for a X870e carbon wifi, how about that? Releasing a bios that bricks my pc and be like: ups, we’re aware of the issue! Be patient guys!

The fck is wrong w them? Do i have to be grateful that a BIOS update bricked the mobo and all they had to say was be patient? What a joke

I’m rmaing this piece of junk and putting a nail in the coffin for this brand. Dont know if Steve from GN would be interested in covering this [***CENSORED***] but oh well, if my report gets to him and hes interested to cover this that would be huge, at least that way people would be aware of this brand to avoid it

Do not install a beta version if you don't want to be a beta tester

Funnily enough, MSI has removed the Beta tag from the download area of AMD 800 series motherboards, so all those BIOS versions are considered as non-Beta (I would not call them stable). But you can tell from the numbering scheme which version is beta:

2A1​

2A2 ​

2A3 ​

2A31 -> Beta​

2A33 -> Beta​

2A4​

2A5 (was removed from the download area - because it was unstable)​

2A52 -> Beta​

2A6 ​

2A73 -> Beta​

2A75 -> Beta​

It did not say it was a beta version, MSI MPG X870E Carbon Wifi

What msi is doing is release a stable bios and then if there are issues are release a beta bios in the forum . At least that's what they're doing with the carbon Wi-Fi.Look like they only releasing stable bios on their main website.

 

[f.meyer156202e5]

Must say that the latest 2 bios is better,but i had also troubles in the begin,and those weren't beta bios.
They must think not every person is a pro with a computer.
I'm 49 and busy with computers from my 17,so lots of expirience.
But if people brake their stuff cause of an update,i can't call that bios as STABLE.
And then they take that bios of the main website,nice testing.

 

[vivek.ra155702d8]

Yep
I mean, It was pretty obvious that this BIOS had something wrong, there was no need to even test it... people don't pay attention.
The file size was noticeably smaller than previous BIOSes, and there was no reason for that haha, as soon as I saw it I got suspicious and didn't download it

Huh? did you look at the size of the bios file inside the archive? it's the same. We're not stupid, been doing this for far too long

MSI does not either - no single BIOS version is labeled as "stable" on the site.

 

[dlomond]

I am just waiting for the carbon bios
