How to find memory slots, DIMM info in linux from dmidecode

Run the DMIDECODE command and look for the data where the word “Physical Memory Array” starts and go through each line to get detailed information. In some new systems you can also use the command dmidecode –s memory and dmidecode –t 17 , where “s” means string and “t” means type. Let’s just use dmidecode here for now.
Summary of the memory data
——————————————————————————————-
Maximum memory that the ON BOARD memory slots can accept is = 8GB
Type of memory = DDR
Error Correction Type: Single-bit ECC
Size of each DIMM = 1024 MB (1GB)
DIMM Speed = 333 MHz (3.0 ns)
Number of DIMM slots = Total 4 DIMM slots and only 2 DIMM slots are filled with 1GB memory each
Note: where ever the Memory module is not installed the “Size” would show as “Size: No Module Installed”
