Persistent VM instability with Ryzen 9 9950X3D and Proxmox 8/9

Well, after bios update, 10 hours without VM reboots and counting. Lets see how long this goes...
Hopefully..... I'm now on this path, after further testing, and getting a replacement set of dimms sent out from Amazon, it looks like I may have been in the sub 1% club and have got faulty dimms, as the replacement dimms so far in the stress tests seem to not be having issues...

How have your VMs held up any reboot? Or has the BIOS update helped?
 
Yep, there is clearly a substancial change in stability after this bios update. Now going over the CPU Type, testing X86-64-v3 (from v4) to see if I can make them completely stable. Will report back.
 
I’ve been running stably with the ram at 4800mhz for 4 days now, even with upping the tick rate on the SCUM server I’m running to 128 just to see and had no issues, my Minecraft server that’s pretty heavily modded has been absolutely fine aswell. The BIOS update just came out a couple of days ago for my board, so I’ve just updated Proxmox, and just in the process of updating the board, and then hoping I can run EXPO at 5800Mhz… will report back
