what is Rambus Memory? Rambus is a chip to chip interface design that is system wide, allowing up to 800 MHz transfer rates. It allows data transfer through a simplified bus that operates in a high frequency range. Rambus uses a low voltage signal swing with data transfer on both edges of a synchronizing clock pulse. The Intel Pentium IV CPU is designed to take full advantage of this new, extremely fast memory design. What is DDR Memory? DDR memory, or Double Data Rate memory, is an evolutionary new memory technology that doubles the data through put to the processor, or CPU. It is an evolution of SDRAM, which leverages the existing production and environment to provide higher PC performance. What is meant by Registered memory? "Registered" is a means of "Buffering" the memory in SDRAM. This means that the clock signal is boosted across the entire array of memory chips so that the computer sees a clean sharp clock signal instead of a weakening clock signal as it progresses along the length of the memory path. Registered memory must be supported by the system board and cannot be mixed with "Unbuffered" modules. You must have only Registered memory to use Registered memory.

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.
