When it comes to adding system memory, the general rule of thumb is the more, the better. On average, doubling the amount of memory in your system will give you ample "space" to work and make an obvious difference in overall speed, especially with today's memory-hungry applications, such as office programs and graphics-intensive games. You'll be able to run more programs at once, and your system will be less likely to lock up or behave strangely. You'll also find it easier and faster than ever to edit graphics and sound. The bottom line is that adding memory makes your computer more efficient and allows you to do more things at once. This memory module is compatible with all laptops incorporating the above spec.
