Linux Check Ram Speed and Type Commands

Linux check ram speed and type commands

The procedure is as follows:

1. Open the terminal application or log in using ssh command.
2. Type the “sudo dmidecode --type 17” command.
3. Look out for “Type:” line in the output for ram type and “Speed:” for ram speed.

Let us see all examples and commands in details.

Installation

Use the apt command/apt-get command to install dmidecode on a Debian or Ubuntu Linux:
sudo apt install dmidecode
Fedora Linux user, type the following dnf command:
sudo dnf install dmidecode
CentOS/RHEL/Oracle Linux user, run the following yum command:
sudo yum install dmidecode
SUSE/OpenSUSE user, run the following zypper command:
sudo zypper install dmidecode

How to check ram speed and type on Linux or Unix-like system

Open a shell prompt and type the following command as root user:
$ sudo dmidecode --type 17
OR
$ sudo dmidecode --type 17 | more
Sample output:

# dmidecode 2.9
SMBIOS 2.4 present.

You can just grep speed (see grep command) and skip all other the details using the following syntax:

dmidecode --type 17
sudo dmidecode -t memory | grep -i speed
dmidecode --type 17  | grep -i speed

Sample outputs:

	Speed: 1333 MHz (0.8 ns)
	Speed: 1333 MHz (0.8 ns)

Say hello to lshw

You can use the following command too:
$ sudo lshw -short -C memory
Sample outputs:

/0/0                            memory         64KiB BIOS
/0/55/45                        memory         1MiB L2 cache
/0/55/46                        memory         256KiB L1 cache
/0/55/47                        memory         8MiB L3 cache
