analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 2.40 GHz - 3.40 GHz
available frequency steps: 3.40 GHz, 2.40 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 2.40 GHz and 3.40 GHz. The governor "ondemand" may decide which speed to use within this range.
current CPU frequency is 2.40 GHz.
cpufreq stats: 3.40 GHz:1.29%, 2.40 GHz:98.71% (107)
the same for CPU 1-3. Obviously the hardware limits are recognozed wrong from kernel.
same to me: I've an OC Q9550 3.6GHz (FSB 425 x 6 resp. 8.5 => 2.55GHz resp. 3.613GHz). CPU-Z on Windows shows all correct.
