Timo,
dmidecode can show what RAM sockets are populated if your motherboard
supports retrieval of this information.
- From 'man dmidecode'
dmidecode is a tool for dumping a computer's DMI (some say SMBIOS)
table contents in a human-readable format. This table contains a
description of the system's hardware components, as well as other
useful pieces of information such as serial numbers and BIOS revision.
Thanks to this table, you can retrieve this information without
having to probe for the actual hardware. While this is a good point in
terms of report speed and safeness, this also makes the presented
information possibly unreliable.
