Thank you Mira for pointed out, that the regex is not strict enough on your
system. Originally, I limited the strictness as a trade-off to the command
length. However, by slightly modifying the output, the command line can be
shortened and a higher level of strictness can be achieved:

dmidecode -t16,17 | grep -P "^\t(Max[^:]*city|Size|Part)" | sed -Ez "s/\n(\tP[^\n]*)/\1/g" | sort
