This outputs total, used, free, shared, buffer/cache, and available memory in a human-readable format.

For detailed hardware information, use `dmidecode` (requires root privileges):

“`bash
sudo dmidecode –type memory
“`

This displays comprehensive details about each memory module, including size, speed, manufacturer, and serial number.

Another useful command is:

“`bash
cat /proc/meminfo
“`

This file contains detailed information about system memory usage and configuration.

Tools like `htop` or `top` also display memory usage dynamically during system operation.

Understanding RAM Specifications

When examining your system RAM, several key specifications help define its performance and compatibility:

  • Capacity: The size of the RAM module, typically measured in gigabytes (GB).
  • Speed: Measured in megahertz (MHz), indicating how fast the memory operates.
  • Type: Common types include DDR3, DDR4, and the newer DDR5, each with different performance and power characteristics.
  • Form Factor: The physical size and shape, such as DIMM for desktops and SO-DIMM for laptops.
  • Number of Slots: Indicates how many RAM modules can be installed on the motherboard.

The following table summarizes common RAM types and their characteristics:

RAM Type Typical Speed (MHz) Voltage (V) Common Use Form Factor
DDR3 800 – 2133 1.5 Older desktops and laptops DIMM / SO-DIMM
DDR4 1600 – 3200 1.2 Modern desktops and laptops DIMM / SO-DIMM
DDR5 3200 – 8400+ 1.1 Latest desktops and laptops DIMM / SO-DIMM

Understanding these specifications will help you verify that your system RAM meets your performance needs and is compatible with your hardware.
