Guide To Know How To Install RAM. It is usually sold in multiples of 16 megabytes: 16, 32, 64, 128, 256, 512, 1024. This means that if you currently have a system with 64 MB RAM and you want at least 100 MB RAM total, then you will probably need to add another 64 MB module.Once you know how much RAM you want, check to see what form factor (card type) you need to buy. You can find this in the manual that came with your computer, or you can contact the manufacturer. An important thing to realize is that your options will depend on the design of your computer.
Most computers sold today for normal home/office use have DIMM slots. High-end systems are moving to RIMM technology, which will eventually take over in standard desktop computers as well. Since DIMM and RIMM slots look a lot alike, be very careful to make sure you know which type your computer uses. Putting the wrong type of card in a slot can cause damage to your system and ruin the card.You will also need to know what type of RAM is required. Some computers require very specific types of RAM to operate. For example, your computer may only work with 60ns-70ns parity EDO RAM. Most computers are not quite that restrictive, but they do have limitations. For optimal performance, the RAM you add to your computer must also match the existing RAM in speed, parity and type. The most common type available today is SDRAM.
Additionally, some computers support Dual Channel RAM configuration either as an option or as a requirement. Dual Channel means that RAM modules are installed in matched pairs, so if there is a 512MB RAM card installed, there is another 512 MB card installed next to it. When Dual Channel is an optional configuration, installing RAM in matched pairs speeds up the performance of certain applications. When it's a requirement, as in computers with the Mac G5 chip(s), the computer will not function properly without matched pairs of RAM chips. Some manufacturers seal the case and request that the customer have an authorized technician install RAM. If you're set to open the case, turn off and unplug the computer. Ground yourself by using an anti-static pad or wrist strap to discharge any static electricity. Depending on your computer, you may need a screwdriver or nut-driver to open the case. Many systems sold today come in tool-less cases that use thumbscrews or a simple latch.
