I know that I can check CPU info via cat /proc/cpuinfo and memory info via cat /proc/meminfo.

But cat /proc/meminfo yields results like the following:

I want to learn more about the clock speed of the memory (in Mhz?).

How do I get that information?

I think an answer is the dmidecode command :

dmidecode -t memory

Which output bios informations about memory on your computer.

The outoput is something like :

SMBIOS 2.5 present.

Handle 0x1000, DMI type 16, 15 bytes
Physical Memory Array
    Location: System Board Or Motherboard
    Use: System Memory
    Error Correction Type: Multi-bit ECC
    Maximum Capacity: 8 GB
    Error Information Handle: Not Provided
    Number Of Devices: 4

Handle 0x1100, DMI type 17, 27 bytes
Memory Device
    Array Handle: 0x1000
    Error Information Handle: No Error

  • Without being able to run a command as root, I don't know how you can found those informations.

you need to be a root user to get information about anything related to system
