Ciao a tutti,
ho da poco acquistato un notebook hp che monta il processore Intel Celeron Dual Core
Ho configurato quasi tutto, quello che mi manca è il throttling del processore dal momento che per linux ancora non ci sono i driver.

Su windows (solo win7) ho notato che la gestione del throttling viene effettuata (la frequenza cambia in relazione al profilo energetico scelto), ma i core restano sempre alla stessa temperatura (la stessa rilevata anche su linux) ed il voltaggio non cambia.

Quello che mi chiedo è in quali rischi posso imbattermi utilizzando il processore sempre alla massima frequenza, più precisamente:
- Possono verificarsi danni al sistema?
- Possono verificarsi danni alla batteria?
- Dal momento che anche su windows il voltaggio e la temperatura non cambiano, l'unica differenza è il throttling, si ridurrebbe parecchio la durata della batteria usando linux?

Ciao

Ciao

Sei sicuro che sia un Celeron e non un Atom che appunto non ha il frequency scaling??

Puoi fornire il modello esatto di CPU installato?? (cpuinfo)

Hai verificato che il demone cpufreqd e relativi moduli siano installati??

Di rischi, per il momento, non ne corri tanti ma certo con la prossima estate potresti avere qualche problema di surriscaldamento.

Ciao Ciao, Moreno

Mi scuso per il ritardo della risposta ma è stato un periodo un pò impegnato.

- eseguito sensors-detect per ricerca moduli
- temp sempre superiore ai 40° (con punte di 45,46)
- frequenza sempre 1200
- il throttling è possibile in quanto su windows funziona
PS: possibile che su internet non si trovano info su questa cpu??...bah!
