linux command ram type [closed]

Question

I'm trying to determine the currently installed ram type of my linux machine by running the command 'dmidecode' but there must be an error because the ram type and other things are still unknown!?

# dmidecode 2.11
SMBIOS 2.4 present.

Handle 0x001A, DMI type 17, 27 bytes

    Array Handle: 0x0019
    Error Information Handle: Not Provided
