Bonjour à tous!
J’ai récemment ajouté de la ram au pc de travail de mon frère passant de 4Go à 16. (on s’est dit que comme ça il aurait le temps de voir venir.). C’est de la ram DDR4.
On s’est aperçu que seul le channel A semble être détecté, et que le B ne reconnais que 64MB de ram, malgré le fait qu’il semble être affiché 32Go pour le maximum.
Voici ce que me donne dmicode -t memory

et memconf (utilisé parceque je n’était pas sûr de comprendre le fait qu’il y aie 4 entrées):

Ce que je ne comprends pas, ce le fait qu’il semble être considéré qu’il y a 3 sockets mémoire (alors que sur la carte, il y en a bien que 2). Et le fait que seul 64MB du second slot soit reconnu (et ça concerne toujours ce slot, même si j’échange les barrettes).
Est-ce un problème de ce solt? Y a-t-il des solutions pour diagnostiquer mieux ce soucis?
Merci de vos réponses!
