Linux: Ram Riegel/maximalen Ram auslesen

Oft steht man vor dem Problem, das ein RAM Riegel defekt ist oder man einfach nur den vorhandenen Speicher beim Server, Pc oder Laptop erweitern möchte. Nur wie findet man heraus, wieviele RAM Slots verfügbar sind bzw. wie diese belegt sind?

Unter Linux geht dies ganz einfach wie folgt:

dmidecode –type memory

Die Ausgabe sollte dann in etwa so aussehen (Daten sind von meinem recht alten Laptop):

SMBIOS 2.4 present.
