i've built up a new openSUSE server on a mobo: ASUS M3A78-CM, BIOS r1903 cpu: AMD 2.8GHz Phenom II X4 920 (Black) @ BIOS, i've overclocked the CPU by 33% from 2.8Hz -> 1.33 x 2.*8 = 3.7GHz. booting to OS, the reported(/available) CPU freq is NOT that which the BIOS reports. questions: (1) is this a bug, or expected behavior for OC'ing? (2) if a bug, is it in kernel, or BIOS? (3) if not a bug, how does one monitor _actual_ CPU speed in openSUSE? details ... uname -a Linux server 2.6.27.25-0.1-default #1 SMP 2009-07-01 15:37:09 +0200 x86_64 x86_64 x86_64 GNU/Linux checking, cpufreq-info cpufrequtils 004: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to http://bugs.opensuse.org, please. analyzing CPU 0: driver: powernow-k8 CPUs which need to switch frequency at the same time: 0 hardware limits: 800 MHz - 2.80 GHz available frequency steps: 2.80 GHz, 2.10 GHz, 1.60 GHz, 800 MHz available cpufreq governors: conservative, userspace, powersave, ondemand, performance current policy: frequency should be within 800 MHz and 2.80 GHz.
