hello, i haven't understand in deep how to set the maximum mhz on my poor cpu!

why kernel recognize 1.33Ghz if is 1.83Ghz?

what is real cpu freq???
according to lscpu -e=MHZ
     MHZ
1832.600
1832.600
1832.600
1583.356

but watch -n0 cat /sys/devices/system/cpu/cpufreq/policy0/scaling_cur_freq /sys/devices/system/cpu/cpufreq/policy1/scaling_cur_freq /sys/devices/system/cpu/cpufreq/policy2/scaling_cur_freq /sys/devices/system/cpu/cpufreq/policy3/scaling_cur_freq

say

1583440
1584049
1583409
1583533

what is the real mhz velocity?

i have lot of different tool for set and scal gov and mhz/ghz like

cpufreq-aperf            cpufreqd                 cpufreqd-set             cpufreq-set              cpu-info                 
cpufreqctl.auto-cpufreq  cpufreqd-get             cpufreq-info             cpuid-dump               cpupower 
x86_energy_perf_policy

what i need to use? and i can set manually it on /sys/?

thank you!
