DDR2 SDRAM Memory
DDR2 SDRAM stands for double data rate synchronous dynamic random access memory; it is the component in your personal computer system responsible for many basic but integral operations happening in the background. Computer processors are extremely fast in terms of data processing, and data storage components like hard drives are extremely slow in comparison. RAM or random access memory is the middleman that allows these components to work well together. It is a place where data is temporarily stored, which is fast to read and write from. Without RAM, having a fast processor will mean nothing; your computer won't even boot up
How do I Install SDRAM memory?
You motherboard will have at least two SDRAM slots next to each other. These are typically located near the processor slot in your motherboard or the one with the fan and heatsink assembly protruding outward from the motherboard. SDRAM has a 'key' in the copper array at the bottom of the component, also called the terminals, which ensures you can never insert a RAM stick the wrong way. The same goes for laptop memory slots.
What do I check before buying RAM?
First of all, check the spec sheet for your motherboard and determine whether it takes DD2 SDRAM. Motherboards are neither forward nor backward compatible with newer or older standards, so ensure you are using one that will accept your RAM. This is also relevant to notebook RAM. This is good precaution because while newer versions of DDR RAM have the key in different places to keep you from using incompatible RAM with your motherboard, if you neglect to check for compatibility before buying one, you will end up with a RAM stick that you cannot use on your system.
How do I install DDR2 SO-DIMM RAM sticks?
SO-DIMM stands for small outline dual in-line memory module, and is the standard type of computer memory for notebooks and other small computers and devices like all-in-one computers and network routers. Similar to normal SDRAM, these sticks have notches or keys distinct from other versions. To replace or install a SO-DIMM RAM stick, push the two thin metal fasteners outwards to allow the RAM to be ejected upward and pull out the stick. Install the new stick by pressing the stick in completely until you cannot see the terminals, and clip the fasteners by pushing the stick down to secure the installation.
