Comment savoir quel type de ram est utilisé
Imaginez que vous venez d’ajouter une barrette de RAM sur votre carte mère et que vous voulez vous assuré qu’elle a les même caractéristiques que l’ancienne, et bien pour ça aussi il existe une commande: il vous suffit d’utiliser lshw
(en précissant la class mémoire)
Exemple d’utilisation (Attention, il faut l’utiliser avec les droits administrateurs) :
1 |
sudo lshw -C memory |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 |

sudo dmidecode -t memory |
