Je me suis fait aider pour overclocker le cpu en modifiant des paramètres dans le bios.

Cela a fonctionné pour cette configuration pour Ubuntu et Windows

Dans le bios -> AI Tweater

CPU Ratio Setting : [23.0]

Intel (R) SpeedStep (TM) Tech : [Disabled]

Xtreme Phase Full Power Mode : [Enabled]

BCLK Frequency : [160]
 
PCIE Frequency : [100]

CPU Voltage Mode [Manual]

Fixed Voltage [1.25000]

Current CPU Core Voltage [1.248V]

Ubuntu 18.04 et Windows 10 démarrent sans difficulté

J'ai essayé de monter le "CPU Ratio Setting : [23.0]" à 24.0 mais le bios n'accepte pas cette modification et passe directement à 25.0

de même le "Fixed Voltage [1.25000]" a été augmenté à 1.3

Ubuntu 18.04 arrive jusqu'au gestionnaire de démarrage GRUB. Mais ensuite un kernel panic défile sur l'écran.

Existe-t-il des actions à faire sur Ubuntu pour faciliter, favoriser l'overclocking ?

Merci d'avance ;0)
