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 Complementos cargados:fastestmirror, langpacks centos-sclo-rh | 3.0 kB 00:00:00 centos-sclo-sclo | 2.9 kB 00:00:00 Loading mirror speeds from cached hostfile * base: mirror.unimagdalena.edu.co * epel: mirror.espoch.edu.ec * extras: mirror.unimagdalena.edu.co * nux-dextop: mirror.li.nux.ro * updates: mirror.unimagdalena.edu.co * webtatic: us-east.repo.webtatic.com Resolviendo dependencias --> Ejecutando prueba de transacción ---> Paquete lshw.x86_64 0:B.02.18-7.el7 debe ser instalado --> Resolución de dependencias finalizada Dependencias resueltas =============================================================================================================== Package Arquitectura Versión Repositorio Tamaño =============================================================================================================== Instalando: lshw x86_64 B.02.18-7.el7 base 321 k Resumen de la transacción =============================================================================================================== Instalar 1 Paquete Tamaño total de la descarga: 321 k Tamaño instalado: 937 k Is this ok [y/d/N]: y Downloading packages: lshw-B.02.18-7.el7.x86_64.rpm | 321 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Instalando : lshw-B.02.18-7.el7.x86_64 1/1 Comprobando : lshw-B.02.18-7.el7.x86_64 1/1 Instalado: lshw.x86_64 0:B.02.18-7.el7 ¡Listo!
Una vez instalado el programa, procedemos a ejecutar el comando de la siguiente forma …
