Where is RAM listed?

9nine9 · 11-27-2007, 12:16 PM

In Fedora 8 which program do I use to see how much RAM I have?

I installed what I think is a 256MB stick next to an existing 256MB stick but I just want to be sure.

Code:

cat /proc/meminfo

You can also use the command "free".

Looks like I've only got 254236 kB

Which means the computer isn't even recognizing the other stick I put in. But it's not having any problem booting up like it did when I installed a brand new stick the other day, which turned out to be defective. The one I put in today came out of another computer and I know the stick is good.

I wonder what the deal is here.

use dmidecode or lshw to see how much memory the system sees, what type of memory it is and what slot it is installed in..

Code:

it-etch:~# lshw -C memory

  *-memory
       description: System Memory
       physical id: 1000
       slot: System board or motherboard
       size: 1GB
       capacity: 2GB
     *-bank:0
          description: DIMM DDR Synchronous 533 MHz (1.9 ns)
          product: KHU006-QIA
          vendor: 7F98000000000000
          physical id: 0
          serial: A036F583
          slot: DIMM_1
          size: 1GB
          width: 64 bits
          clock: 533MHz (1.9ns)
     *-bank:1

          vendor: FFFFFFFFFFFFFFFF
          physical id: 1
          serial: FFFFFFFF
          slot: DIMM_3
          width: 64 bits
          clock: 533MHz (1.9ns)

Are these programs part of the Fedora 8 Live CD installation or will I need to install them?

farslayer · 11-28-2007, 07:02 AM

I don't know if they are on the live CD or not.. if they are not available you would need to install them.

Only one way to find out... try the commands

Ok, lshw wasn't installed on my system so I did

Code:

yum install lshw

It appeared to install, the last 2 lines of the readout in the terminal window being

Code:

Installed: lshw.i386 0:B.02.12.01-1.fc8
Complete!

But when I try to run it in the terminal window, I get 'command not found'.

What am I doing wrong?

I know it got installed because when I do 'whereis lshw', I get

lshw: /usr/sbin/lshw /usr/share/lshw /usr/share/man/man1/lshw.1.gz

And if I do 'man lshw', I get the man page.

try (as root) /usr/sbin/lshw -C memory

IIRC, /usr/sbin isn't in the path.

reddazz · 11-28-2007, 05:42 PM

You need to switch to root using "su -" or enter the full path of the command.

9nine9 · 11-29-2007, 07:08 AM

Yep, that did the trick. And I should have known enough to do that but I've forgotten a lot of stuff since the last time I used Linux (Red Hat 8.0)

Thanks for the help.
