Wczoraj wymieniłem procesor w swoim laptopie na T9600. Procesor działa w porzadku, lecz zastanawia dlaczego mam dostępne tylko 3 częstotliwości taktowania do wyboru poprzez cpufrequtils.

Jak widać dwukrotnie na liście występuje 2.8GHz. Czy to jest jakiś błąd? Z tego co widziałem to większość osób z tym prockiem ma jeszcze opcję 800MHz. Czy da się to jakoś włączyć programowo?

Może coś trzeba w biosie włączyć?
U mnie są 4 różne tryby:

Bios w moim laptopie ma bardzo ograniczone opcje konfiguracyjne. Czy ktoś z forumowiczów posiada procesor T9600? Jeżeli tak to czy mógłby podać jakie ma dostępne częstotliwości taktowania?
