What CPU Type for a Threadripper 7980X 64-Core?

[NuAngel]

I've got a Windows 11 machine that keeps bluescreening with nothing useful in the logs; in fact I have multiple. Windows 10 seems fine, but if the VM is "upgraded" to Windows 11, the issues seem to crop up. If there's something I can do to the guest OS, I'd love to -- but I've tried troubleshooting by changing the virtual hardware's CPU type.
I've tried x86-64-V2-AES (the default) and x86-64-V4 (compatible with this physical CPU), and I've tried setting it to "Host."

Host does seem to reduce the reboots / crashes, but nothing has fixed them. I'm wondering if changing to one of the "AMD" specific types ("EPYC" or EPYC-ROME or something?) if that might help, but I figured I would cut to the chase and just ask if anybody can recommend what I should set with my particular CPU?

Proxmox Virtual Environment 9.1.4

changing cpu type between those two will not make any difference for blue screening, you need to diagnose the blue screen

Good to know. But my question still remains, is there a specific "AMD" type CPU I should choose for these Threadrippers?

 

[gasherbrum]

if you are concerned about performance pick the correct AMD cpu type, x86-64xxxxx has the best compatibility

For best mitigations of vulnerabilities, and probably same performance as host, pick EPYC-Genoa(-v2), which is also Zen 4 based.

...pick the correct AMD cpu type...

Right, hence my question. Threadripper isn't a choice, so what should I pick? leesteken's answer is most helpful so far!
