Bonjour,
pour reprendre le titre, j'ai un Macbook pro 13" de mi-2009.
J'ai voulu lui redonner un petit coup de fraicheur en passant de 4Go (2x2Go) d'origine à 8Go (2x4Go). J'ai donc passé commande pour de la corsair, seulement dès lors que j'installe ces nouvelles barrettes, mon système (Lion 10.7.4) devient instable.
J'ai fait des tests sur la RAM avec memtest et il s'est avéré qu'il y avait des erreurs.
J'ai renvoyé les barrettes.
Les nouvelles sont revenues, et rebelotte, système instable/test de la mémoire/erreurs.
Donc j'ai peur que le problème ne vienne d'ailleurs. Pourtant aucun problème avec les barrettes d'origine.
Est ce que je peux faire quelque chose? C'est SAV obligatoire?
Voilà ce que me donne memtest pour 2 passages:
