Memory


I'm going to update the memory on my Linux box. It is dragging and very slow, being an old machine and not a lot of memory in it. Does Linux, I'm using Fedora 9, tell you that memory has been added? How do I find out if it has been added?

It should see the memory just fine. You may need to make a modification if you go over 4GB.

type

free

It should show the memory stats there.

With the older machine, can I even go over 2 GB. It takes PC2100, 184 pin. Not sure what the processor is, but like I said, the machine is old.

When you boot up, the memory will be displayed as part of the BIOS self-test. That info then gets passed to the OS.

The BIOS may tell you.. you could try checking with lshw.

Code:
it-lenny:~# lshw -C memory

  *-memory
       description: System Memory
       physical id: 1000
       slot: System board or motherboard
       size: 1GiB
       capacity: 2GiB
     *-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: 1GiB
          width: 64 bits
          clock: 533MHz (1.9ns)
     *-bank:1
          description: DIMM DDR Synchronous 533 MHz (1.9 ns) [empty]
          vendor: FFFFFFFFFFFFFFFF
          physical id: 1
          serial: FFFFFFFF
          slot: DIMM_3
          width: 64 bits
          clock: 533MHz (1.9ns)
As you can see the system I am currently on will accept a maximum of 2GB of RAM I currently have 1GB of RAM installed.

Thank you very much for that command. I've been trying to figure that one out. I found the lshw, but didn't know how to use it. I will try that when I get home tonight. Thanks again.

lshw

You may not have lshw, but it is easy to find and install and is very useful. As ever, google man lshw and find.

http://linux.die.net/man/1/lshw

You might just run "lshw" as su to see how much it sees, that is a lot. It should show your processor right on top.

Where I live, it is easy to find 128MB PC2100 RAM sticks, but more difficult to find, or find cheaply, 256MB, with 512MB more difficult still. Few mother boards from the era have more than two, or at most, three RAM slots, and many have but one. I believe that you can use faster RAM with the same standard, such as PC2700, if you can find it.
