They do use a little more memory, but with 4GB of RAM, I think it is not pragmatic to worry about every 16 bits of memory used. Also if you use graphic tools like blender, the performance on 64 bit systems is often better. > In the terminal: > > sudo yum install linux-server > sudo yum install linux-image-server > sudo yum install linux-headers-server > > After a reboot, 'free-m' displayed 4 GB RAM.. > If anyone can tell me more about these packages, it will be really > helpful.. I'm not sure how these packages brought about the change.. Well, I am quite sure the server packages are compiled for the kernel. So the kernel must have been configured with support for bigmem. These will support till 64 GB of RAM afaik. --- Ashok `ScriptDevil` Gautham _______________________________________________ To unsubscribe, email [email protected] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
