Ryzen 7 3700X on archlinux

This post will document problem(s) I may or may have encountered running the 3700X on archlinux and the fix that I might have applied

Geekbench score

The score is OK for 3700X AFAIK, but I haven’t test with sustain load yet: https://browser.geekbench.com/v4/cpu/13909162

The sound card

The very first problem after booting was static and crackling noise from the sound card:

0b:00.4 Audio device: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller

A quick googling lead me to a very old questions on askubuntu.com: https://askubuntu.com/questions/405071/static-and-crackling-in-my-hdmi-audio. Seem like it has been a common problem on ATI card but I haven’t got a chance to experience it, archwiki also got some line about the fix: https://wiki.archlinux.org/index.php/ATI#HDMI_audio

In short, edit


append the prameter tsched=0 will resolve the problem.

load-module module-udev-detect tsched=0

Thermal sensors

The second problem I encounter was no thermal sensors working, lm_sensors report 0 RPM Fan speed and no temperature of any kind:

$ sensors
Adapter: ISA adapter
cpu_fan:        0 RPM

Luckily, archwiki have a note for my exact case: https://wiki.archlinux.org/index.php/Lm_sensors#Asus_B450_motherboards_with_Ryzen_CPU . After installing the AUR package and append the kernel parameter and reboot, the sensors was fine.
