MSI Z890-P - New Bios but MSI Center Live update find nothing

[msie15e602e8]

Hello,

My card : MSI Z890-P WI FI (MS-7E34)

If i read ;
https://www.msi.com/Motherboard/PRO-Z890-P-WIFI/support

There is a new BIOS : 7E34v1AC1 2026-03-10

But Live Update find nothing...

This bios is important for anticheat EA JAVELIN : "- Implemented the anti-cheat mechanism."
(TPM 2.0B)

Any problèms with this new BIOS ?

I remember having the same problem in January... But one day it was offered as a solution.
However, the January update lasted over 15 minutes with... a black screen (I don't know if it's due to RAM calibration, but it seems abnormally long).

--------------------------------

Windows 11 PRO up to date

Actual bios : 7E34v1AC0 2026-01-15

Overclocking with Intel 200S is active (And XMP for the RAM) and no problems

- Corsair Vengeance RGB DDR5 32 Go (2 x 16 Go) 6000 MHz CL38 1.35V (QVL List))

Well, use M-Flash to update it, no need to wait MSI Center or LiveUpdate.

 

[plutomate]

MSI Center only supports BIOS update for those BIOS ends with 0 in its name (ex. 1AC0 if available).

 

[pandaz]

just use Mflash to update will be faster：）

Thanks for these answers

If I understand... AC1 is a beta ?
And If I understand correctly, if I don't use M-Flash, I have to wait for an AC0 version?

 

[laportein151f02d0]

If I understand... AC1 is a beta ?

Yes

And If I understand correctly, if I don't use M-Flash, I have to wait for an AC0 version?

No, you do not wait for AC0 because it already exists.
If you want to use MSI Center, as per plutomate's post, you have to wait for AD0.

 

[msie15e602e8]

Thank you for these details
I don't know MSI, and this is new to me For the moment I have no other updates for live update, other than the December update in ACO

I've seen : ABO, AAO, ACO, AC1.... (ADO.... I don't see) It's complex if you don't have the decoding key

 

[laportein151f02d0]

To be clear: you are not able to update your bios chip to 7E34v1AC1 using MSI Center Live update because this is a beta version as plutomate wrote.
7E34v1AC1 is the lastest bios version so far, there is no AD0 yet.
Svet and pandaz wrote to use mflash. You can update your bios to AC1 using Click Bios X and MFlash which is located on the top row, center right.
here is an MSI youtube video showing how

you can download the file from
https://www.msi.com/Motherboard/PRO-Z890-P-WIFI/supportyou can copy it directly to your properly formated USB drive and extract the zip file on the USB drive.
restart your PC and press the DEL key on a wired keyboard until you enter Click Bios X where you will see the M Flash icon on the top row center right.
Good Luck.

I don't know MSI, and this is new to me

Welcome to MSI then

I've seen : ABO, AAO, ACO, AC1.... (ADO.... I don't see) It's complex if you don't have the decoding key

I will try to be your decoder

1st a few corrections:
* It's not "O" but "0"
* the [ ABO, AAO, ACO, AC1....] are actually [1AB0, 1AA0, 1AC0, 1AC1....]
etc. they are 4 chars, not 3 chars after the "." (beside the "O" & "0" correction)
This is important because of the next explanation:

With introduction of Intel 8xx series,
MSI changed the BIOS naming system.
Intel 8xx series: .xxxy [now has 4 chars after "."]
Intel Older series: .xxx [has 3 chars after "."]

Those who has 4 chars after "." scale differently from those who has 3 chars after "."

If I understand... AC1 is a beta ?

FYI:
Any MSI BIOS that do not ends with "0" is a beta. (or some test version, or something else but not Official)
No matter if it's has 4 chars or 3 chars after "."

And Windows msi auto update apps can provide only Non Betas versions.
(etc. only "official" versions, etc. only those who ends with "0")

How they 3chars(older) vs 4 chars(newer) scale differently?

3 chars examples:
Betas: progression from older to newer versions:
1A1... 1A9, 1A9, 1AA, 1AB... until of rest of English alphabet 1AZ
where the latest (and official in the same time)
version s of 1A* would be 1A0
like:
exmp1: 1A1, 1A3, 1A4, 1A0
exmp2: 1A3, 1AC, 1A0
1A0 is always the latest one from any other 1A* versions before that.

Numbers are increasing progressive from older to newer.
Letters are also increasing progressive [A-Z], from older to newer.

Where 1st are counted the numbers from 1-9 (without 0)
(it start from 1, not from 0)
then after 9 continues with letters from A-Z


With 4chars after the "." this behaviour has changed.
They are now follows more "natural" human's expectations versions changing.

The difference is that 0 is no longer the latest version,
but become 1st version.
I.e. 0 is no longer higher than 9, higher than "Z"
0 become from the latest (newer possible) to the 1st (older possible)

4chars example:
exmp1: 1A40, 1A44, 1A51, 1A60, 1A61
exmp2: 1AC0, 1AC4, 1ACD, 1AD0, 1AD1, 1AD6, 1AD8, 1AD9, 1AE0, 1AE8, 1AEF

0 is now counted and scaled like you expect in mathematics.
etc: 0 is the 1st number unlike with 3 chars.

MSI Center only supports BIOS update for those BIOS ends with 0 in its name (ex. 1AC0 if available).

Yes and No.
Yes to:

MSI Center only supports BIOS update for those BIOS ends with 0 in its name

No to:

(ex. 1AC0 if available).

1AC0 is already available,
and this is older version than 1AC1
and 1AC0 do not contain changes from 1AC1

The correct waiting for official update that would contain changes from 1AC1 would be 1AD0.
[like laportein151f02d0 wrote]

And If I understand correctly, if I don't use M-Flash, I have to wait for an AC0 version?

No, plutomate probably have a typo, means to say 1AD0.

But as everyone said, no need to wait for official versions.
Betas usually are also very reliable like official one.

Also better flash it with M-Flash and avoid Windows flashing.
(with regardless what BIOS you are going to flash, official or beta)
It's more reliable.

@svt

- Actually, I've been using MSI "Gaming" graphics cards since the 970, then the 1660, and the 3060, but I've used MSI laptops (high-end models) in the past.No problems.

Laptops... That's ancient history (Back then I used my Amiga computer). I no longer use ASUS or Gigabyte motherboards (too many problems), and my last one was an ASRock (no problems with Intel).
This one is a pre-built PC with an MSI motherboard (it was cheaper than building it myself with the rising price of RAM)


- Thanks for the additional details... Now I know everything

- I've known about M-Flash for a long time, but I'm going to wait a bit because there have been issues with the EA Javelin anti-cheat program recently, and there's a fix in the update, but I don't know if EA Javelin will actually use it..... or not, and I wouldn't want him to consider me a cheater (This happened with the latest EA JAVELIN update with error 95 which they fixed (thankfully)

(Sorry for the google translate)

A concrete example
New update today (picture)



As a reminder

1A0 is always the latest one (...)
Letters are also increasing progressive [A-Z], from older to newer.

so

1AD0 is already available,
and this is older version than 1AC1
and 1AD0 do not contain changes from 1AC1

So I'm going to wait (currently I have no problems with the computer) because what interests me is

- Implemented the anti-cheat mechanism.

which is not in the last update

Nope, you got it wrong.

To clarify:

1A0 is always the latest one (...)

and 1AD0 do not contain changes from 1AC1

No! This explanation was only for those BIOSes who has 3 chars after the "."
Your board BIOSe's has 4 chars [1AD0], not 3 chars.

So those do not apply for your board.
You should check for your board the 4chars case not the 3 chars case.

1AD0 is already available,
and this is older version than 1AC1
and 1AD0 do not contain changes from 1AC1

1AD0 is the latest and newer that 1AC1.
1AD0 contain all changes from any other older BIOSes. (in 99% of cases, sometimes some changes are pulled back or downgrade if they are causing some issue)

The new BIOS only list the newest additional changes,
it doesn't repeat all the changes from older versions.

which is not in the last update

Go for "7E34v1AD0" it's the latest update.

 

[pandaz]

1AD0 is newer than 1AC1 so just try it out

 

[msie15e602e8]

So...

1AD0 contain all changes from any other older BIOSes. (in 99% of cases, sometimes some changes are pulled back or downgrade if they are causing some issue)

With "Implemented the anti-cheat mechanism." (who disappeared)

If this function no longer appears in the new BIOS version, it's because it... was causing a problem (?) (for the moment ?)
Therefore, we can conclude that it's wiser and more reasonable to use LIVE Update instead of M-Flash, if I understand correctly.

With "Implemented the anti-cheat mechanism." (who disappeared)

It's not disappeared, just the changes from older BIOS versions are not repeated over the new BIOSes.
They only list what's new compared to prevision BIOS version.

Therefore, we can conclude that it's wiser and more reasonable to use LIVE Update instead of M-Flash, if I understand correctly.

As I told before in my opinion best use M-Flash in any cases,
with regardless what BIOS version you are flashing.
