En indeterminadas ocasiones es necesario aumentarle o cambiarle la memoria ram a nuestra pc, a veces no hay problema con tan solo comprarla y ponerla en la tarjeta madre y listo, sin embargo, algunos modelos anteriores a las CI o Amd, es necesario ver qué tanta memoria es capaz de redireccionar el procesador de la pc.
Uno de los comandos que he usado para esto, es:
dmidecodeSu uso normal es el siguiente:
sudo dmidecode
El cuál arrojará toda la información de hardware de la pc, parecido al siguiente código:
# dmidecode 2.12
SMBIOS 2.7 present.

Ahora sí quieren saber el máximo de memoria ram soportada de manera directa, entonces el comandos es:
sudo midecode |grep -i "Maximum Capacity:" | uniqLa salida será:
Maximum Capacity: 32 GB
Y eso sería todo. Muchas gracias por visitar.
