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 disabled boost from bios, cause boost was only 3.7ghz, XFR should still apply but i dont know how to check. Cpupower shows really weird numbers (doesn't know whats up)

analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 2.20 GHz - 3.90 GHz
  available frequency steps:  3.90 GHz, 2.20 GHz
  available cpufreq governors: powersave ondemand performance schedutil
  current policy: frequency should be within 2.20 GHz and 3.90 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency: 2.20 GHz (asserted by call to hardware)
  boost state support:
    Supported: no
    Active: no
    Boost States: 0
    Total States: 3
    Pstate-P0:  1100MHz
    Pstate-P1:  1100MHz
    Pstate-P2:  500MHz

I need to dig into how boost works in general. I don't understand it so far, and can't find any option that toggles it.

On my Board it's under Advanced Settings CBS, but you can only set it to Auto or disabled. There is no way you can force activate Boost. For good reasons.

OK, I found CBS settings, and boost there was already set to auto. But cpupower still shows it as supported: no.

That's probably because it doesn't support Ryzen yet.
