how do i find out how much ram my box has

Hello everyone,

I have a quick question for you all. On Windows, I can right click on my computer > properites and see how much ram a pc has.

How would i find out how much ram my pc has on linux? I am running Fedora Core 2.

Thank

try

Code:

free

hope this helps. look at the man pages for the format of output.

oh, should have specified. that is a command. issue it from a console.

That is the output of free -m

Code:

            total      used      free    shared    buffers    cached

Mem:          187        183          3          0          9        70

-/+ buffers/cache:        103        84

Swap:          383          0        383

I have 2 pc ram sticks in the box one is a 256 and one is 128 the total would be 384 right .

as you can see on the Swap output is says 383 is that the total of ram in the pc

Thanks

Just a thought, but when you turn on your computer, doesn't it tell you how much RAM you have?

Hi,

All your memory related details will be inside in the file /proc/meminfo. Please issue this command in the shell prompt.
#cat /proc/meminfo

Actually Swap is the amount of disk space allocated for use when memory is getting low.
I think your free -m output shows 187mB of system RAM* so it looks like something is wrong somewhere if you are sure about the memory sticks you have installed.

* I could be wrong about this so perhaps wait for a more experienced poster to comment before doing anything drastic :)

this is the output of cat/proc/meminfo

Can you tell me what line is my ram according to my calculations i should have 384 of ram

The MemTotal line indicates how much RAM you have (in kilobytes). From what your system is telling you, either:[list=1][*]Something is wrong with your memory[*]You actually have a 128 MB stick and a 64 MB stick (128 + 64 = 192)[/list=1]

I would doubt #1 because if the memory was bad or failing, then your computer would crash and burn all the time. In addition to that, memory sticks are not sold as 192 MB in size. What I'm getting at by that is, if one of your sticks was bad (as in completely broken/dead),the computer would only see one memory stick and report its capacity. So, since 192 is not a standard memory size, the computer sees and recognizes more than one memory stick. So if you are positive you have two (and only two) memory sticks in the machine, then the computer is seeing and recognizing both.

I would bet lots of money that it's just a case of mistaken capacity and that you actually have a 128 MB and a 64 MB stick. If you're dual booting with Windows, and Windows reports something else, make sure that number doesn't include virtual memory or anything along those lines.
