Zenith II Extreme Alpha instability and restarts with BIOS 1603

[beastie]

My system has ben running perfectly stable with the following hardware:

MB: Zenith II Extreme Alpha
PROC: TR 3990X
RAM: 128GB G,Skill Trident Z 3600Mhz
GRAPH: EVGA RTX3090

I multiboot diferent OS's mainly Windows 11/ Proxmox 7.1 / VMware ESXi 7 and had been fine since I built the system almost two years ago and about 8 months with BIOS 1502.

Since the update to BIOS 1603 with AGESA 1.0.0.7 I'm having spontaneous shutdowns and restarts without any pattern and with any of the OS I boot, in Proxmox (Linux) I can see the following messages preceding the crash:

Apr 21 10:46:55 pve3 kernel: mce: [Hardware Error]: Machine check events logged
Apr 21 10:46:55 pve3 kernel: [Hardware Error]: Corrected error, no action required.

Reverting to BIOS 1502 makes the system rock solid and no unexpected shutdowns/restarts.

Someone have the same problem?

Is the any way to open a ticket with Asus to help in troubleshooting it?

Thanks!

Sent you an pm.

Hope Asus will release a fixed 1603 bios!
Or better: with new agesa 1.2.0.7

Thank you.

Hi Beastie and Mappi75,

Wow, I was about to quit and buy a new motherboard.

It started when I bought a new NVMe this week to install in my pc and install a fresh W11 Pro on it.

My pc:
MB: Zenith II Extreme NOT Alpha
PROC: TR 3970X
RAM: 64GB G,Skill Trident Z 3600Mhz
GRAPH: EVGA RTX3080TI
GRAPH: Asus STRIX 1080TI

At a moment I thought maybe it was the new NVMe or the RAM or even the Power Supply the problem, but it was not.

I was getting a lot of random errors during install.
Random errors I got durint the install of Windows 11 Pro.

• 0xc000000e
  
• 0x8007025d during Windows Install
  
• PC Reboot by itself randomly while installing Windows
  

Have removed a pair of the 4 x 16GB RAM and still the same problem.

I had reset to default the BIOS 1603 and set back my RAM to 3600MHz and got the same problem.

One thing got me curious is that if I don't set the RAM to 3600 and leave it to the default 2100Mhz, it was going fine for the install of the Windows.
But the memory was not at the good speed.

It's a that time I found you post and Oh yeah, I said to myself, why I didn't try to downgrade to 1502...

Thank you very much Beastie and Mappi75, after 7 hours of troubleshooting, you nailed it.

I have no more issue on BIOS 1502, stable memory, no random reboots and the NVMe goes find without any errors! :cool:

@micboule interesting that you have the problems too a non alpha board!

So bios 1603 is 100% faulty and asus should remove this bios from their website.
Before more people crash their systems!

Hello, I know this is an old thread, however I've had these issues forever as well and in my particular case, my motherboard 4-pin Molex Connector and cable were defective, effectively depriving my motherboard of some of it's PCI power usually going to the Videocard.  So make sure you are using one, and that it's connection / cable is good / solid.

I have the 3990X and a Asus 3090, but with the 3970X and a 1080TI it was also happening. I am using Windows.

EDIT: PS: To clarify, I was getting random motherboard resets as a symptom. Even sometimes when idle.

Just my 2 cents.  Hope it helps.
