In computing terms, the more RAM that is on your computer, the more jobs it can process at once. More than any other PC component, the fastest and least expensive way of increasing the overall performance of your personal computer, make it faster, run easier and overall just behave better, is by adding more RAM (Random Access Memory).<click here>

ABOUT RAM: <click here> Memory: What Is It?
Memory is a type of temporary storage that holds the programs and data you are currently running. When you see the term "memory" by itself, it means the computer's main random-access memory (RAM), which is what this article covers.

RAM(Random Access Memory), generally is used to describe a computer's dynamic storage area, where raw data is made available to the CPU, and which serves as a conduit for processed data received from the CPU. Everything uses RAM and therefore everything from the Operating System to intensive 3D gaming benefits from the increased amount of RAM. The greater the memory, the better performance you'll experience when running multiple applications or working with larger files.

How Do You Know What's Good?
The primary factor with memory is its capacity or how much data it can hold.
Memory capacity is measured in megabytes (MB) or gigabytes (GB), with bigger being better.

It is fairly simple to view how much RAM your computer may have. To do this all you must do is go click on My Computer and then right click and select properties and system information.

Note: EDO, SDRAM, DDR1 and DDR2 memory can not be used on the same DIMM slots due to an alignment change in the PCB[/i]. The TYPE of RAM you will need is dependent on the socket found on your laptop

Different types of memory (SDRAM, DDR-SDRAM, and RDRAM) are distinguished mainly by the speeds they can handle.

Frequently Asked Questions:
What do terms like "PC2700" and "DDR333" mean?

These terms indicate a combination of memory type and memory speed. For a variety of reasons, they are not user-friendly terms. What's it all mean? The PC133, DDR333, and DDR400 numbers are the front side bus speeds at which the RAM can be accessed. This equals MHz per cycle.

Think about it as a speed limit on DDR's two-lane highway.
The DDR333 highway is designed to support combined traffic speeds up to 333MHz (2 lanes traveling at 166MHz). While DDR400 memory allows traffic speeds up to 400MHz (2 lanes at 200MHz).

But wait, the RAM says it is PC-2700. What's that? PC- is a new naming standard for the speed of DDR memory. It's equivalent to the theoretical speed of the RAM.
