This question already has an answer here:

I found that into the directory /sys/block I can list the block devices

[root@srv block]# ls
loop0  loop3  loop6  ram1   ram12  ram15  ram4  ram7  sda
loop1  loop4  loop7  ram10  ram13  ram2   ram5  ram8
loop2  loop5  ram0   ram11  ram14  ram3   ram6  ram9

But is this the real number of the RAM sticks installed on the server?

When I navigate to one ram* folder and list the file size I get this value:

[root@srvram1]# cat size

Can you give me some information about this directory and how to get the size of the RAM stick?

    The ram-devices (/dev/ram*) are just possible ramdisks. – jofel Aug 1 '14 at 10:18
  • I'm using Center 6.2. Is there any text file where I can see this information. – Peter Penzov Aug 1 '14 at 11:12
  • @jofel is right -- those are ramdisks, some systems create them by default at boot. They don't have anything to do with the number of sticks or amount of physical RAM, etc. – goldilocks Aug 1 '14 at 11:59
