What is SDRAM? SDRAM is an acronym for Synchronous Dynamic Random Access Memory. The term "Synchronous" means that the clock cycle of the memory is exactly synchronized with the clock cycle of the bus. Every calculation and operation a PC performs is timed according to a clock ticking millions of times each second, its clock cycle or megahertz rating. If the memory clock cycle is not in sync with the bus clock cycle, system problems will occur. What is Cache Memory? Cache, pronounced "cash", is a high-speed memory designed to supply the processor with the most frequently requested data and instructions. The information located in the cache memory can be accessed many times faster than information in the system''s main memory. The more information your system can retrieve from the cache memory, the more efficient the system will run. Level 1 (L1) cache, also referred to as Primary Cache, is normally located inside the CPU chip. Level 2 (L2) cache, also referred to as Secondary Cache, was normally located on the system board near the CPU in the past. In today''s systems, both are physically located within the CPU and as a result are not upgradable.
What You Need to Know Adding random access memory (RAM) to your system is the cheapest and most effective way to make it run faster. With the addition of more RAM, you''ll be able to keep more programs open at once, speed up program launches, and experience fewer system crashes. Plus, it''s a pretty easy upgrade to make, requiring little technical expertise. Your computer uses RAM to temporarily store the data that will be processed by the central processing unit (CPU). Information from a word-processing document, or spreadsheet must first be held in RAM before the CPU can process it. So the more RAM you have, the more data is available for the CPU to work with at one time.
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.
