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.

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.
