En voulant booster un peu mon laptop, j’ai d\u00e9cid\u00e9 de lui ajouter 8GB de RAM en plus des 4GB d’origine. Ceux d’origine \u00e9tant en 1066Mhz, je me suis dit que de prendre 8GB en 1333Mhz et profiter du dual channel serait judicieux…<\/p>\n

Seulement, une fois install\u00e9es, les deux barrettes n’\u00e9taient pas reconnues (toujours 4GB de Ram). La solution: fouiller dans la documentation en ligne de chez Lenovo. En effet, les canaux ne sont pas agenc\u00e9s par emplacement de slots, mais plut\u00f4t crois\u00e9s: canal 1: un slot sous le clavier, l’autre sous la machine, idem pour le canal 2. (source: support Lenovo en ligne<\/a>).
\nUne fois les canaux respect\u00e9s, tout roule: 8GB en 1333Mhz et 4GB en 1066Mhz en attendant de passer \u00e0 16GB. (Et oui, les VM \u00e7a bouffe pas mal de RAM).<\/p>\n

La commande sudo<\/span> dmidecode --type<\/span> 17<\/span><\/span><\/code> permet de v\u00e9rifier tout \u00e7a:<\/p>\n
