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?
BIOS: Both this
available frequency steps: 2.80 GHz, 2.10 GHz, 1.60 GHz, 800 MHz
and (presumably, as you didn't show it) /var/log/messages would confirm this. The identifiers for the corresponding frequencies are stored in ACPI tables and/or MSRs, so if the BIOS "supported" overclocking, it would have to update these tables/registers (the actual frequencies get calculated from these identifiers). The value /proc/cpuinfo reports is simply one of the frequencies reported as available.
