Неправильное определение частоты CPU при разгоне. [SOLVED]

Проц Core2Duo E6320 1,86GHz.
В биосе путём повышения fsb догнал его до 2,8. При загрузке биоса всё правильно пишет! А в /proc/cpuinfo всевремя 2333 выдает! причем до каких бы не гнал! что до 2,6 или 2,4 всеравно 2,3 показывает!
зы! может в ядре что не так поставил? в dmesg аот это смущает:
mtrr: your CPUs had inconsistent variable MTRR settings
mtrr: probably your BIOS does not setup all CPUs.
mtrr: corrected configuration.

Загрузился с лайв сиди винды ХР и запустил там cpu-z! всё правильно определяет! Куда всётаки копать?
