Finding RAM size details in Linux for a System admin is very easy task. We can use free command to check how much RAM is present in our system. But when you want to find how many RAM/Memory sa lots are present in your system is bit tricky one. One way to do open your system and check what sa lots are there and how much RAM. Instead of doing this as a Hardware engineer we can use a command to check which sa lot is having below details.

• How much RAM
• Speed of the RAM
• Maximum RAM supported by that machine
• RAM location etc.

As you are already aware of dmidecode command to get all the system hardware info. We will use the same command for getting our RAM details.

• How do I check physical memory on Linux? 4 ways to check size of physical memory (RAM) in Linux. Using free command. First command is free. Using /proc/meminfo file. Another way is to read memory info from proc filesystem. Using top command. Famous top command also lists physical memory information in very clear way.

Jan 27, 2013 Finding RAM size details in Linux for a System admin is very easy task. We can use free command to check how much RAM is present in our system. But when you want to find how many RAM/Memory sa lots are present in your system is bit tricky one. One way to do open your system and check what sa lots are there and how much RAM. Check RAM on Linux using free. The most popular command in order to check your RAM on Linux is to use the “free” command. $ free total used free shared buff/cache available Mem: 40216 16 480 Swap: 0 0 0.

To Find RAM details like maximum RAM, location of RAM etc we can use -t option with dmidecode as shown below

dmidecode -t 16

Output:

# dmidecode 2.11
SMBIOS 2.7 present.

Handle 0x000F, DMI type 16, 23 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: None
Maximum Capacity: 16 GB
Error Information Handle: No Error
Number Of Devices: 2

If you see the above output we can figure it out how much maximum RAM this machine support, number of RAM devices and location etc.

To get actual RAM details such as how many sa lots, actual RAM present etc, use -t 17 option in dmidecode command

dmidecode -t 17

Output:

# dmidecode 2.11
SMBIOS 2.7 present.
