[Kernel-packages] [Bug 379873] Re: CPU Frequency Scaling Monitor reports incorrect CPU speeds when overclocked
I found a solution with 'acpi=off'. Now show the correct cpu MHz but doesn't work Frequency Scaling. :~$ sudo dmidecode -t processor | grep Speed Max Speed: 2700 MHz Current Speed: 3051 MHz :~$ dmesg | grep MHz [0.00] tsc: Detected 3033.877 MHz processor vagrale@vagrale-desktop:~$ lscpu | grep MHz CPU MHz: 3033.877 :~$ cpupower -c all frequency-info analyzing CPU 0: no or unknown cpufreq driver is active on this CPU CPUs which run at the same hardware frequency: Not Available CPUs which need to have their frequency coordinated by software: Not Available maximum transition latency: Cannot determine or is not supported. hardware limits: Not Available available cpufreq governors: Not Available Unable to determine current policy current CPU frequency: Unable to call hardware current CPU frequency: Unable to call to kernel boost state support: Supported: no Active: no analyzing CPU 1: no or unknown cpufreq driver is active on this CPU CPUs which run at the same hardware frequency: Not Available CPUs which need to have their frequency coordinated by software: Not Available maximum transition latency: Cannot determine or is not supported. hardware limits: Not Available available cpufreq governors: Not Available Unable to determine current policy current CPU frequency: Unable to call hardware current CPU frequency: Unable to call to kernel boost state support: Supported: no Active: no :~$ cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 16 model : 6 model name : AMD Athlon(tm) X2 215 Processor stepping: 2 microcode : 0x1c7 cpu MHz : 3033.877 cache size : 512 KB physical id : 0 siblings: 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fdiv_bug: no f00f_bug: no coma_bug: no 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 nonstop_tsc extd_apicid eagerfpu pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt hw_pstate vmmcall npt lbrv svm_lock nrip_save bugs: tlb_mmatch apic_c1e fxsave_leak sysret_ss_attrs bogomips: 6067.75 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) X2 215 Processor stepping: 2 microcode : 0x1c7 cpu MHz : 3033.877 cache size : 512 KB physical id : 0 siblings: 2 core id : 1 cpu cores : 2 apicid : 1 initial apicid : 1 fdiv_bug: no f00f_bug: no coma_bug: no 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 nonstop_tsc extd_apicid eagerfpu pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt hw_pstate vmmcall npt lbrv svm_lock nrip_save bugs: tlb_mmatch apic_c1e fxsave_leak sysret_ss_attrs bogomips: 6067.75 clflush size: 64 cache_alignment : 64 address sizes : 48 bits physical, 48 bits virtual power management: ts ttp tm stc 100mhzsteps hwpstate -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/379873 Title: CPU Frequency Scaling Monitor reports incorrect CPU speeds when overclocked Status in linux package in Ubuntu: Expired Bug description: The reported frequencies of an overclocked Core 2 Duo are incorrect. Benchmarking and performance testing can confirm that the CPU is running at the overclocked speeds, but the values reported through cpuinfo are the standard stock speeds. CPU has been overclocked from stock 3.00GHz to 3.60GHz. This can be confirmed through dmidecode (output attached). The issue is that cpuinfo (and related utilities) all report the stock CPU speeds instead. This is only a visual/reporting issue. The CPU is still throttling correctly, and the speed is correct as per the overclocking ratio. i.e. (tested and confirmed in benchmarks & Bogomips) Reported 2.00Ghz = (3.6/3.0 * 2.0) = 2.40GHz True Clock Speed Reported 3.00Ghz = (3.6/3.0 * 3.0) = 3.60GHz True Clock Speed There are a few reports of
