Na początku dodam, że skalowanie jest ustawione na profil "Performance".
Standardowo procesor jest taktowany częstotliwością 2,7GHz (13.5x200), Debian wykrywa to prawidłowo. Kiedy podkręcę go (w BIOS-ie oczywiście) na 3.3 (11x300), podczas startu BIOS-u pokazuje wszystko poprawnie, natomiast polecenie:

PS
Jeśli to ważne, to dodam, że używam Debiana Wheezy z KDE.
PS2
Przy częstotliwości 3.0GHz (10x300) Debian "widzi" z tego tylko 2.8.
