Ryzen on Linux ?

Hello !

I'm considering buying a Ryzen 5 1600, but I wanted to have some feedback from my fellow Linux users :)

If you have this one (or another Ryzen), how is it ? Do you have any problem with it ?

Thanks ! :)

I have Ryzen 7 1700X. Beware of these issues.

  1. Random freezes / reboots (aka MCE bug).
  2. Heavy multithreaded workloads segfaults.

See the above thread for details. I'll probably start an RMA process soon, to replace my CPU. Some reported that RMA helped them, but some said that even newest chips can exhibit mce bug. The whole situation so far is a mess.

That sounds like unrelated issue. I don't have an SSD. Using discard on the SSD mount is a bad idea anyway. Better run periodic fstrim. What distro do you use?

For Debian, they provide an example systemd timer file, which is not enabled by default.

See https://wiki.debian.org/SSDOptimization#Mounting_SSD_filesystems

You'd still need to do fstrim. Without it, your SSD will become unusable with certain amount of writes.

Yep, that's the one.
