Se você quiser ver a listagem de bancos de memória e quais estão usados use:
# dmidecode -t memory | sed -ne '/Memory Device/,/Part Number/ { /Size:/h; /^[[:space:]]*Locator:/ {p;x;p}; /Speed:/p}' | paste - - - | tr -s '\t' | expand -t 1,20,50
É visualmente perfeito no que se refere a informação lógica (modelo e dimensão da memoria) e física (como ela esta na placa-mãe), reflete ate o posicionamento de como as memoria se encontra nos slots , o que me impressionou bastante .

Boa noite. Posso confiar noa informação retornada do comando "dmidecode --type memory"? Preciso fazer um upgrade de memória para meu note, que atualmente tem apenas 3GB de ram e gostaria de saber se posso confiar na resposta do comando que diz que a capacidade por slot é 8GB, totalizando 16GB. Posso mesmo comprar 2 pentes de 8GB? E se puder, devo escolher o 10600 (igual ao da minha memória atual) ou 12800? Desde já agradeço pela ajuda.
