How to Use more than 3GB RAM on 32-bit Ubuntu

I only have 2 gigs of ram so I have not tried this myself. It looks pretty interesting though, and I figured someone here might benefit from it.

How to Use more than 3GB RAM on 32-bit Ubuntu

Posted by admin on September 23rd, 2008 Email This Post Email This Post

Currently It seems that the current 32 bit editions of Ubuntu can only take advantage of 3GB (sometimes a little more) of physical memory. Desktops and gaming rigs using 6 and 8 GB of RAM are ubiquitous now.I am having a ubuntu desktop with 5GB RAM and i want to use all the available memory for gaming.

Procedure to follow

You need to install the following packages and restart your PC

Code: Select all
sudo apt-get install linux-restricted-modules-server


Code: Select all
sudo apt-get install linux-headers-server


Code: Select all
sudo apt-get install linux-image-server linux-server


That’s it after rebooting you should be able to see all the memory available in your system.

I guess I should have checked before posting this. I didn't realize someone else had done so already. Of particular interest I found were the comments listed at that site under the article. Apparently there are drawbacks to this idea as well. In any case it's always nice to know one's options.

Come to think of it it may have been in the blog after an announcement :)
It's good to have such posts
I have 4 GB paired DDR2 memory laying around - but no mobo for DDR2 :(
