Bug ID: 419598
Summary: Ksysguard shows wrong CPU frequency from Ryzen 7 3700X
Product: ksysguard
Version: 5.17.5
Platform: RedHat RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: ---
SUMMARY
Ksysguard shows wrong CPU frequency from Ryzen 7 3700X
OBSERVED RESULT
Because Ksysguard reads the CPU speed from /proc/cpuinfo, the maximum frequency
is always displayed. Wich makes this sensor useless. I'm not sure
If Ksysguard would read the frequency from
/sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq
it would display correct values, and at the same time the average values would
be displayed as nice integers.
EXPECTED RESULT
Correct values for CPU frequencies
