Bonjour,
J'ai un Asus X555BA, avec 4Gb de RAM installés , sur tous les sites présentant ce portable, il est dit que l'on peut monter à 12 Gb de RAM. Mais en tapant :
sudo dmidecode -t memory
ça me donne:
# dmidecode 3.0
Getting SMBIOS data from sysfs.
SMBIOS 3.0.0 present.

je n'ai donc qu'une capacité totale de 4Gb ?
merci de votre aide, j'ai un peu l'impression de m'être fait avoir...
en outre la barrette installée peut tourner à 2133 MHz, mais elle est configurée à 1866MHz??
