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!

I started experiencing TPM related issues after upgrading to 1603. Gonna revert soon I think!

No issues at all here.

Seems something related to the voltage control: undervolting a bit the SoC and the processor core, is stable like in the previous version.
