Check Free Ram Slots Linux
This is our sixth post on getting hardware information. In this post we will see how to get RAM details such as size, speed, make, maximum capacity allowed RAM etc. We already covered some hardware related stuff in this series so far as given below.
Get BIOS, Firmware, Hardware And Drivers Details in Linux/Unix
Example1: Find RAM size(Total, available, used) in Linux. We can use below five methods to get details.

A lot of different parts make up a good casino site, and there’s even more to get right for a great one. Some of the things we look for include functionality, game selection, Linux Checking Ram Slots live casino options, a reliable customer service, bonuses, availability and trustworthiness. Method-1: Using free Command. Free displays the total amount of free and used physical and swap memory in the system, as well as the buffers and caches used by the kernel. The information is gathered by parsing /proc/meminfo. Suggested Read: free – A Standard Command to Check Memory Usage Statistics (Free & Used) in Linux.

Here is the quick guide to identify your ram, the number of slots and how much it will cost. We are assuming you have downloaded CPU-Z from their website. The trick with CPU-Z is not to look in the Memory tab but use the SPD tab. You can see how many RAM slots your computer has by using the 'Slot 1' drop down list.

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.
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.

If we want to see complete RAM details we can use -t memory option to get the details. Note this is a combination of 16 and 17 options

Some of the valid keywords/types you can use and find different details are as follows.
bios
system
baseboard
chassis
processor
memory
cache
connector

We can even use lshw command to get RAM/Memory details as well Cache details such as L1, L2 and L3 levels.
