Listar carácteristicas de la memoria RAM física usada por tu PC

En linux , podemos verificar las características de la memoria RAM, no solo el tamaño sino también la velocidad y el slot que ocupa en nuestro board.

Para ello hacemos uso del comando lshw seguido de una serie de opciones.

Si no lo tienes instalado en tu linux, procedes a instalarlo de la siguiente forma. La instalación aquí descrita es en un Centos 7.

┌─[11:31:06] [localhost ~]
└─>  ¯\_(ツ)_/¯  sudo yum install lshw
