FEATURES RAM comes in the form of a chip, and to increase memory, you simply plug additional chips in to slots on your computer''s main board. The capacity of a RAM chip is measured in megabytes, or millions of bytes. Most systems now come with 48MB of RAM and up. You should have at least 32MB of RAM for running Windows, but with the ever-growing demand for memory, 64 MB or higher is ideal. BUYING TIPS Before buying additional memory for your computer, consult the hardware manual that came with your computer. The manual will tell you what kind of memory is required for your system. It is also important to check the number of RAM slots in your computer, as there is a limited number on the main board for installing memory (anywhere from two to eight). You can only install as many memory modules as you have slots, so plan ahead. If you want to add or upgrade to 128MB of RAM, for instance, get a single 128MB RAM chip, not two 64MB modules. This will save you one RAM slot for future expansion.

What is These are common Bus speeds used in today''s PC''s. runs at 66 MHz, the clock speed of the bus between the CPU and the memory , or Front-Side Bus as it is called. is a faster main memory bus, transferring data at 100MHz. Up until recently, the fastest common PC bus speed has been 66MHz, so PC-100 represents about a 50% theoretical improvement in speed. Tests have shown a typical speed increase of over 20%. PC-133 runs at the bus speed of 133MHz giving an even more pronounced increase in speed. why did my computer slow down after I installed more RAM? In most cases additional RAM improves system performance. However, there are a few rare times when additional RAM actually makes the system slower. The most common reason for the problem is that the system doesn''t have enough cache to handle the addressing for the additional RAM. If this is your case, the only solution is to upgrade your system or motherboard, as cache cannot be upgraded.

MEMORY BASICS One of the best ways to increase the performance of your computer system is by adding more memory. With additional memory, you can have more programs running at the same time, and work on larger business files like spreadsheets and databases. Easily installed, RAM chips can speed up graphics applications, multimedia and, especially, games. HOW IT WORKS Before information can be processed by a computer, it must first be transferred to a special data storage area called RAM (Random Access Memory). RAM is connected directly to the processor by high speed data pathways. As long as your data is in RAM, the computer''s processor has almost instantaneous access to it. When the processor needs information that is not currently in RAM, it must be loaded from the hard drive and placed in RAM, a much slower process. So the more RAM you have, the higher your system''s overall performance.
