Ubuntu: How to make Ubuntu 32 bit read my 4GB RAM on a Acer Travelmate 3210 notebook?


I have Acer Travelmate 3210 notebook with 4GB RAM, but after I install Ubuntu 32bit Desktop, Ubuntu says my RAM is only 2GB.

How to make Ubuntu use all my RAM? My notebook doesn't seem to support Ubuntu 64 bit.


You can try to enable or install PAE enabled kernel. If you are running Ubuntu 12.04, it should have automatically installed the pae kernel, if it has detected more than 3gb of RAM.

You can also enable it manually, please follow the instructions from this Ubuntu community page.


According to Acer's website, the maximum amount of memory supported by your model is 2GB:

RAM / Max RAM: 256Mb or 512MB / 2GB DDR2-533
