Adding random access memory (RAM) to your system is the cheapest and most effective way to make it run faster.

For example, you can add PC800 modules to a system that was designed for modules, but the memory will run at the speed. How much memory do I need? Ask us and we will tell you every ounce and then a megabyte to spare. The answer really depends on how much and for what your system is used. Upgrading is easy and cost effective. RAM is used every time you open an application, download, play a game or simply turn on your computer. Additionally if you work with or plan to work with digital audio and video more ram is a necessity. The amount of memory you need depends upon how you use your computer. Most applications recommend a minimum of 64MB, and most users desire more than the minimum requirement. Novice User / Administrative If you use your computer to send and receive email, do a little word processing, and are starting to surf the Web, you can get by with 64MB. However, you would benefit from going to at least 128MB of memory. Basic User / Student If you are spending more time surfing the internet, sending and receiving email, and doing word processing along with other applications, you can get by with 128MB, but would benefit from going to 256MB.

You can think of RAM as an incredibly fast hard drive that stores information temporarily instead of permanently. When you start a program it is loaded from the hard drive into RAM. When a program is running in RAM it can run hundreds to thousands of times faster than it can if run directly from the hard drive. The problem is that the capacity of a standard hard drive is many times the size of a computer''s RAM size, meaning it is possible to load so many programs that the RAM can no longer hold them. When that happens, your computer''s virtual memory kicks in, and that''s bad. Virtual memory is simply your hard drive trying to act like a RAM chip. Since the hard drive is so much slower than real memory, programs stutter and sometimes crash when the hard drive has to do a job it was never designed for. There are only two solutions to this problem: close some programs until virtual memory is no longer needed, or add more physical memory. If you can afford it (and current memory prices are low enough that practically anyone should be able to), the latter solution is always preferable.
