He comprado e instalado 4x32GB de RAM ( OWC2666DR4S128S ) en mi iMac (Retina 5K, 27 pulgadas 2020) RAM. Funciona.
Me he dado cuenta de que no se detectan ni el fabricante ni el número de pieza cuando inspecciono y me pregunto si esto es una función de mi instalación o del OWC2666DR4S128S o sólo de MacOSX.
¿Debe MacOSX ser capaz de identificar el fabricante y el número de pieza a partir de OWC2666DR4S128S ?
¿Y tengo que volver a instalar la memoria si indica que no está bien hecha?
También he comprobado esto (por respuesta de @pion)
ioreg -p IODeviceTree -n memory -r
y devuelto
