There is nothing like Zen+ or Zen2 board... There are AM4 motherboards based on different chipsets. All of them supports Zen, Zen+ and Zen2. If you want to install Zen2 in such board you must first ensure it has flashed BIOS that supports new CPU. The piece of software that includes CPU microcode is called AGESA. It is responsible for initializing CPU and memory at least. And it is redistributed as BIOS upgrade by motherboards manufacturers.
So if you want to install Zen2 CPU on AM4 motherboard, you need to make sure it has flashed BIOS with AGESA 1.0.0.1 that brings support for Zen2 CPUs. And that AGESA 1.0.0.1 is something newer than 1.0.0.7. It still supports Zen and Zen+, but since it is dedicated for Zen2, the versioning restarts from 1.0.0.0 what gets people confusing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690085 Title: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1690085/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
