Has anyone successfully got an Epyc 7V13 processor working? If so, what motherboard do you have? I have a Tyan S8030 motherboard which works fine with a 7302 processor, but I'm needing more cores so I decided to try a 7V13 processor. I'm running the latest BIOS (4.02). When the system boots I get the Tyan logo and the bottom right corner shows code FFFF. I tried 4 sticks of RAM, 1 stick of RAM in different slots, and no RAM at all and I get the same thing.
