[mdlug] lshw and memory capabilities

[Carl T. Miller]

I'm not aware of dmidecode giving false readings, but anything
is possible.  Usually I trust that dmidecode is accurate and have
never run into any issues.  If the original documentation for the
device (motherboard or component) disagree with dmidecode,
I'd refer to the first paragraph of the man page, included below.

c


dmidecode  is a tool for dumping a computer's DMI (some say SMBIOS) ta‐
ble contents in a human-readable format. This table contains a descrip‐
tion  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.
