Hi, my cpu is 2.8GHz, but anyone know why cat /proc/cpuinfo shows that its only 800MHz? Thanks. processor : 0 vendor_id : AuthenticAMD cpu family : 16 model : 6 model name : AMD Athlon(tm) II X2 240 Processor stepping : 2 microcode : 0x100009f cpu MHz : 800.000 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nopl nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt hw_pstate npt lbrv svm_lock nrip_save vmmcall bogomips : 5625.44 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 48 bits physical, 48 bits virtual power management: ts ttp tm stc 100mhzsteps hwpstate processor : 1 vendor_id : AuthenticAMD cpu family : 16 model : 6 model name : AMD Athlon(tm) II X2 240 Processor stepping : 2 microcode : 0x100009f cpu MHz : 800.000 cache size : 1024 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 1 initial apicid : 1

This is the speed the CPU is running at the moment
you can run the following command:
cpupower frequency-info
you may see something like
Total States: 7
Pstate-Pb0: 4100MHz (boost state)
Pstate-Pb1: 3800MHz (boost state)
Pstate-P0: 3500MHz
Pstate-P1: 3500MHz
Pstate-P2: 3500MHz
Pstate-P3: 3500MHz
Pstate-P4: 1400MHz
If you change your CPU cpufreq governor you may get another idle CPU
frequency and in most cases with the demand on the system the frequency
should go up.
