и много много еще интересного. Используя опции фильтруем вывод по интересующему меня разделу:
# dmidecode --type memory
В выоде идет описание всех слотов и модулей, при чем не только ОЗУ, также о материнской плате, процессоре и всей прочей требухе. Вот и наш пациент:
Handle 0x001C, DMI type 17, 27 bytes

Формфактор - DIMM. Вот и ответ на вопрос. Полистал, посмотрел в каких слотах стоят планки, какие частоты, объемы. Ок. Нашел то что искал. Далее уже для утоления жажды любопытства и интереса.
Раз уж добрались до таких недр, давай проверим как звать материнку и что из нее еще можно сделать. Набор опций в мануалах описан.
$ dmidecode -t
dmidecode: option requires an argument -- 't'
Type number or keyword expected
Valid type keywords are:
bios
system
baseboard
chassis
processor
memory
cache
connector
slot
Выбираем нужную опцию и смотрим:
# dmidecode --type baseboard
# dmidecode 2.11
SMBIOS 2.3 present.
Handle 0x0002, DMI type 2, 8 bytes
Base Board Information
Manufacturer: Gigabyte Technology Co., Ltd.
Product Name: 8I915PL-G
Version: x.x
Serial Number:
Далее просто гуглим модель материнки и смотрим ттх. Например nix.ru
А процессор тут такой:
# dmidecode --type processor
# dmidecode 2.11
SMBIOS 2.3 present.
