I was going to say that I am on the latest BIOS, but then I noticed a new one out on the 15th, so will patch that when I get back to the office. Am working remotely a lot at the moment, so cant tweak much. I ended up putting an IP controlld power supply under y dsk to I can hard reboot it remotely if it locks up. Which works nicely, but would rather it was stable :-) Will see about downclocking the RAM too when I am physically in front of it. Nice to see that someone has had no problems at all with 12 on this. did run some Epyc machines in the cloud under both 11 and 12 for a time and never got those to lockup, so I know it not that Zen is unstable in general. Just have had a few issues with this machine spevificly. -pete.
