Outra opção é o comando lshw (man page) - ele fornece resultados sobre muitas coisas, incluindo os slots de RAM. A saída completa é muito longa, mas sudo lshw -short fornece um resumo incluindo uma linha por slot de RAM, independentemente de haver ou não RAM no slot. Ou para informações completas sobre RAM, mas omitindo tudo o mais que você poderia fazer sudo lshw -class memory .
A saída que recebo de sudo lshw -short é:
