je serais bien tenté de voir ce que ça donnerait avec un autre cpu s775 plus light en 45 nm

tu geres ca comment cpufreq ? faudrait que je regarde aussi

j'ai installé et c'est tout, les 4 cores sont passés de 2400 à 1600 mhz quand c'est au repos

bah il tourne à fond là oui

Bitman · « **Réponse #14248 le:** 25/02/13 22:42 »

j'ai tenté les cpufreq-set -g conservative ondemand etc ca change rien

t'as bien le speedstep d'activé dans le bios ?
