Linux view memory information, and other hardware information Dmidecode commands

Because want to change memory, want to look at the memory model, frequency, simple search the command can be viewed with the Dmidecode command.

DMIDECODE-T Memory

This command can view almost all the information in memory, including frequency size, etc.

In addition, this command is powerful to almost check any hardware information including BIOS CPU, should be only on the DMI bus can be checked

Dmidecode-t
Dmidecode:option requires an argument--' t '
Type number or keyword expected
Valid type keywords is:
Bios
System
Baseboard
Chassis
Processor
Memory
Cache
Connector
Slots

In addition Dmidecode This command is very powerful, almost can check all the hardware information

Dmidecode--help
Usage:dmidecode [OPTIONS]
Options are:
-D,--dev-mem file Read memory from device FILE (default:/dev/mem)
-H,--help Display this help text and exit
-Q,--quiet less verbose output
-S,--string KEYWORD only display the value of the given DMI string
-T,--type type only display the entries of given type
-U,--dump do not decode the entries
--dump-bin file dump the DMI data to a binary FILE
--from-dump file Read The DMI data from a binary FILE
--no-sysfs do not attempt to read DMI data from SYSFS files
--oem-string N only display the value of the given OEM string
-V,--version Display the version and exit

ExampleView server model: Dmidecode | grep ' Product Name ' to view the serial number of the motherboard: Dmidecode |grep ' Serial numbers 'View System serial number: Dmidecode-s system-serial-numberView memory information: Dmidecode-tView OEM Information: dmidecode-texecuting the dmidecode command without an option typically outputs all hardware information. The Dmidecode command has a useful option-T, which can output information by the specified type, and if you want to get information about the processor, you can do it:
