My current CPU speed is (1253.029MHZ) less than the minimum (1400MHZ)? It's a new computer, is there something wrong with it?

  • Mine reports minimum of 500MHz but can't go below 800MHz. I just assumed that the hardware reports the wrong value. Dec 16, 2020 at 16:07

If there is something wrong can't be judged by the output of lscpu. I've never seen the current frequency to be much lower than minimum frequency but considering how complex CPU's are it is not a surprise either. The Power Governor can through ACPI States either increase for extra performance or decrease or throttle the clock to reduce power and heat for each CPU core individually. It can also insert STOPCLOCK's where CPU's can skip heartbeats. AMD has Cool'n'Quiet and PowerNow! that can affect voltage and frequencies. The motherboard has an influence and maybe even the powersupply. But especially look at the temperatures of the CPU cores.

Linux exposes details about the frequencies through the /sys interface. lscpu uses these for it's summerization. But look at the kernel parameters directly if you suspect you have issue, especially when the system is under load.

find /sys -name freq

The Kernel description on cpu frequency is documented here Linux Kernel CPUFREQ
