J'ai acheté et installé 4x32GB de RAM ( OWC2666DR4S128S ) dans mon iMac (Retina 5K, 27 pouces 2020) RAM. Cela fonctionne.
J'ai remarqué que ni le fabricant ni le numéro de pièce ne sont détectés lors de l'inspection et je me suis demandé si c'était une fonction de mon installation ou du OWC2666DR4S128S ou simplement de MacOSX.
MacOSX devrait-il être capable d'identifier le fabricant et le numéro de pièce à partir de OWC2666DR4S128S ?
Et dois-je réinstaller la mémoire si elle indique qu'elle n'est pas bien faite ?
J'ai également exécuté ceci (selon la réponse de @pion)
ioreg -p IODeviceTree -n memory -r
et a renvoyé
+-o memory <class IOService, id 0x100000162, !registered, !matched, active, busy 0, retain 4>
