[Mini-Tutorial] Enabliing 4 GB RAM in 32-bit Ubuntu.

I have seen and heard that 32 bit operating systems (linux) take only 3 gB of RAM even if more than 3 gB is installed. Here is my experience and solution to it.

I recently bought a 32-bit laptop with 2 gB of RAM. I had a spare 2 gB RAM with me, so I installed that 2 gB RAM in my laptop hoping that I will get 4 gB of RAM. The BIOS shows 4 gB of RAM installed, but OS shows only 3 gB. I was a bit shocked. Googled for a bit and found a simple solution.

Need to install PAE linux kernel header. My OS was ubuntu 10.04 Lucid Lynx. I fired up my terminal and typed:

aptitude install linux-generic-pae linux-headers-generic-pae


and bam it showd 4 gB. For more detailed info, go here. here.
