I recently increased my desktop pc to 4GB RAM from 2GB but do not discover
any marked improvement. Do I need to do any configuration in order to
optimize the performance? Your advice is highly appreciated.
Despite the number of people who repeat "the more RAM, the better,"
that statement is *not" literally true. More RAM helps you only up to
a point, and for most people 2GB is at (or sometimes even past) that
point.
Beyond that point, more memory doesn't hurt, but it doesn't help
either. More memory helps only when what you are running causes you to
use the page file instead of RAM. If you're in that situation, adding
RAM reduces (or eliminates) page file use, and speeds up performance.
If you're not in that situation, the RAM does next to nothing for you.
Unless you use particularly memory-hungry applications, for example,
applications that do video- or photo-editing, 2GB is enough for almost
everyone running Vista. Sorry to tell you that you probably wasted
your money by upgrading the RAM.
