To Improve ur computer performance is add RAM. Installing new RAM is quite straightforward for most PC owners, but if you’re not confident of your abilities, have a store technician do the work.
Find out how much memory your computer has. Here’s how:
In windows xp click on Start, then Control Panel, then Performance and Maintenance, then System. In other versions of Windows, double-click on My Computer, then double-click on Control Panel, then double-click on System.
In MAC find the Applications folder, double-click on the Utilities folder, and double-click on Apple System Profiler. In Mac OS 9 or earlier, select the Apple System Profiler (usually found in the Apple menu).
Check your manual or manufacturer’s Web site to determine whether there are open memory slots on the motherboard. Also see what the maximum amount of memory your computer can take, as well as the type, category and speed of memory it uses. For example, PC2100 DDR 133 MHz RAM means PC2100 is the type, DDR is the category, and 133 MHz is the speed in megahertz.
Compare your current memory with the maximum. You have two choices: Add new memory in open slots; or, if all slots are full, replace the existing memory with new, greater-capacity modules.
Modern memory modules are integrated onto circuit boards. In SIMMs the circuits appear on one side of the board, and in Dual Inline Memory Modules (DIMMs) they appear on both sides. SIMMs must be used in pairs, but DIMMs can be used singly. There are small electrical contacts on the bottom of the modules. These plug into small motherboard slots or “banks” so that the memory can communicate with the CPU.
PC RAM types include Synchronous Dynamic RAM (SDRAM), Double Data Rate Synchronous Dynamic RAM (DDR SDRAM) and Rambus RAM (RDRAM.) SDRAM and DDR SDRAM are the most common types. DDR memory has about double the bandwidth of single rate SDRAM. Designed by Intel, Rambus RAM comes in Rambus Inline Memory Modules (RIMMs.) While it can be up to 10 times faster than SDRAM, it is expensive and can only be installed on a motherboard with Rambus sockets. Memory also comes in Error Correction Code (ECC) and Non-Error Correction Code (Non-ECC). ECC memory can correct errors which occur during the transmission of data; Non-ECC cannot.
