Rookie question for Mint 9 amd64 main RAM

[cultural deviant]

Like the title says I'm running Mint 9 amd64 main on a dual-core Pentium D 2.8GHz. I have 5GB of RAM installed but the System Monitor says that I only have 3.4GB. What's the problem here, and how do I fix it.
I am a linux rookie by all means so please be kind to my stupidity.

Are you sure you have the 64bit version installed?

There have been reports of people downloading and installing iso images that were marked 64 bit but were actually 32 bit.

Run this in a terminal.

Code: Select all

uname -a

I am running the 64 bit version the results are as follows when I run uname -a.

Code: Select all

jason@jasons-laptop ~ $ uname -a
Linux jasons-laptop 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux

If you don't see x86_64 GNU/Linux than you got bunked.

If you did inadvertently install the 32 bit version you 2 options.
1. Redownload and install the 64 bit version.
OR
2. install the PAE Kernel from the package manager.

@ cultural deviant

Where did you get these supposed 'get-deb' files?

They are not repository source files.
A repository doesn't end in "gz, bz2 or gpg"

You should probably go to the main 'Get-Deb' site and find the correct source repositories for what you want to do.

And why do you need a 'Get-Deb' repository anyway? Doesn't the Ubuntu/Mint repositories have what you need?

Get-Deb repositories should look something like these.

Found this at the Get-Deb website >>

removed is a website which comes with a repository for easily installing lots of Ubuntu applications which are not available in the official Ubuntu repositories (mostly updates).

Both the removed.net and removed.net websites are currently down but if you want to use the repositories, there is a mirror you can use instead of the original removed / removed repository.

My 64-bit install "uname -a" ... looks like this >> Linux cbx-vrkalak 2.6.33-5-amd64 #1 SMP Tue Mar 9 09:25:39 UTC 2010 x86_64 GNU/Linux

vrkalak- The removed repo is available in Mint 9 by default it can be enabled in the other software sections. (Although it's useless at the moment as removed is down right now)

Well cultural deviant you're running 64bit alright. I don't know what to tell you about that.

You're getting the removed errors because the site is down, has been for about a week now.
To fix that go to the package manager> Settings> Repositories> Other Software and uncheck the box in front of http://archive.removed/ubuntu.....

The Medibuntu repo does that to me sometimes check back later it'll probably clear it's self up.

So you have no idea why my system says that I only have 3.4 GB of RAM? For the record, the BIOS shows that I have 5GB installed.

Its just a reporting problem from the last edition, if it helps it did not seem to degraded performance in Mint 8. Don't worry be happy.

Help!! Linux ate my RAM!! >> http://www.linuxatemyram.com/

My RAM is being eaten. >> http://www.linuxforums.org/forum/linux- ... eaten.html

These are just a few of the responses to this question ... taken from 'other' Linux distro Forums.
So obviously, this is not an isolated problem.

Search through this Forum, as well as, the Ubuntu Forums for many more topic threads about this issue.

[cultural deviant]

I'm stupid. Please explain this. BIOS says 5GB. Linux system manager says 3.4GB. Terminal says
free -m
total used free shared buffers cached
Mem: 3522 3498 24 0 24 2699
-/+ buffers/cache: 774 2747
Swap: 10315 0 10315

So do I have full use of my 5GB of RAM or not?

Linux isn't eating my RAM, it's not seeing it.

Look at the tab in System Monitor that shows how your resources are being used, there are pie chart type diagrams for RAM and swap usage.
Unless you are maxed out on RAM use and using swap it really doesn't matter if it can't see your missing 1.6gb
