Win11 VM opening many tabs at once crashes proxmox host

I think mine crashed when I stressed the RAM paging heavily but at least it does not crash on every single browser load now.

I just had my first crash with this custom CPU we made. Yep, it's way less often, but the issue still exists.
 
maybe a dumb question, but did either of you run a memtest already? maybe it's just bad ram?
 
otherwise there could be some fault in the cpu too, so current microcode + bios upgrade could also help

current bios is v1.09 (latest @ https://www.minisforum.com/new/support?lang=en#/support/page/download/79), but there have been known to be BIOS issues in the past for this chipset (not just this particular minipc model).

I looked up the microcode files to make sure there are no updates:

Code:
# grep microcode /proc/cpuinfo | uniq
microcode       : 0xa704104

root@SnuUM780:/# cat /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 25
model           : 116
model name      : AMD Ryzen 7 7840HS w/ Radeon 780M Graphics
stepping        : 1
microcode       : 0xa704104

- `vendor_id`: AuthenticAMD / 0x8
- `cpu family`: 25 / 0x19
- `model`: 116 / 0x74
- `stepping`: 0x1

there is no file named "xxx74F01" so there is currently no available microupdate for the 7840 cpu. (following https://github.com/platomav/CPUMicrocodes/tree/master/AMD from https://www.reddit.com/r/linux/comments/15xvpfg/updating_your_amd_microcode_in_linux/)

That is why when installing amd64-microcode (via wget http://ftp.us.debian.org/debian/pool/non-free-firmware/a/amd64-microcode/amd64-microcode_3.20231019.1_amd64.deb) there is no entry in dmesg saying that the microcode has loaded, because there is no firmwire file for this model, i.e. there are no updates even after following https://cyrusyip.org/en/post/2023/01/31/install-microcode-on-proxmox/ .

Maybe there will be a microcode update in the future, but I don't see one for now.

I just had my first crash with this custom CPU we made. Yep, it's way less often, but the issue still exists.
hopefully with software updates in the future it can become more stable, I'm considering reverting back to a custom CPU of x86-64-v4 base + svm
