May 18, 20206 yr I have just upgraded my unraid server to an AMD Ryzen 9 3900x. The problem I am having is that I power up the PC, unraid starts to load and within seconds I get a black screen and the hardware resets and starts all over again. This is an endless loop. Prior to this I was running an AMD Ryzen 7 2700 on the same motherboard and it was working fine. The motherboard is an MSI B450 Gaming Plus motherboard and has the latest 7B86v1D Bios that supports the 3000 series CPUs If I remove the Ryzen 9 3900x and reinstall the Ryzen 7 2700, unraid boots just fine. Below is a link to the video of the bootup process, at attached is a still screenshot of the last thing I see before the hardware resets. https://youtu.be/Fr7Bm8Ijzao Has anyone had seen this before and know of a possible cause. Do I have a faulty CPU, or maybe the motherboard, although up to date, doesn't support the CPU correctly. Edited May 18, 20206 yr by mayhem2408

According to MSIs website, BIOS V19 and higher support the Ryzen 9 3900x. I am running the latest V1D. I have not tried another OS but will see what I can do. This PC has no DVD drive so OS from USB only. I'll try Ubuntu Live tonight.
